How to use
- 01
Pick a mode: choose Add VAT when your price is net (before tax), or Remove VAT when the price already includes tax and you want the reverse calculation that pulls the VAT back out.
- 02
Enter the price and the VAT or GST rate. Open Advanced options to price several units, take a flat discount off before VAT, or add a shipping or service fee and say whether VAT applies to it.
- 03
Read the VAT amount, the net and gross totals, the effective rate and the VAT share of the price — then compare the same base across other rates, or save the figures as a scenario to weigh against another.
Formula
VAT is a percentage charged on the value of a supply. Everything below uses the rate r written as a decimal — a 20% rate is r = 0.20. Adding VAT (your price is net, tax-exclusive): • VAT = net × r • Gross = net + VAT = net × (1 + r) Removing VAT (your price is gross, tax-inclusive — the reverse calculation): • Net = gross ÷ (1 + r) • VAT = gross − net = gross × r ÷ (1 + r) The trap is the reverse direction: the VAT inside a tax-inclusive price is NOT the rate times the gross. At 20% the tax is 20 ÷ 120 = one sixth of the gross, about 16.67%, not 20%. Taking 20% of the gross overstates the tax every time. With the extras (Add-VAT mode): the calculator multiplies the unit price by the quantity, takes a flat discount off that net subtotal before any tax, then adds taxable fees to the base while leaving VAT-exempt fees out of it. VAT = taxable base × r, the net total is the net-after-discount plus all fees, and the gross is the net total plus VAT. The effective rate is VAT ÷ net total: it equals the headline rate unless a VAT-exempt fee dilutes it.
Example
Start simple. Take a net price of 1,000 at a 20% VAT rate. The VAT is 1,000 × 0.20 = 200, so the gross (the price a customer pays) is 1,000 + 200 = 1,200. Now run it backwards in Remove VAT mode: enter 1,200 as a tax-inclusive price and the calculator divides by 1.20 to recover a net of 1,000, leaving 200 of VAT inside the price. Note that 200 is not 20% of 1,200 — that would be 240. The VAT baked into a 20% gross price is 20 ÷ 120, one sixth of it, about 16.67%. Now use the advanced fields (Add VAT mode). Price three units at 1,200 each: the net subtotal is 3,600. Take a 200 discount off before VAT and the net falls to 3,400. Add a 60 shipping fee marked VAT-exempt: it joins the order but is not taxed, so the VAT base stays 3,400. The VAT is 3,400 × 0.20 = 680, the net total is 3,400 + 60 = 3,460, and the gross is 3,460 + 680 = 4,140. Because the exempt shipping dilutes the tax, the effective rate is 680 ÷ 3,460 ≈ 19.65%, a little below the 20% headline. These figures are estimates for pricing — confirm the rules that apply to your supply with your tax authority or accountant.
Definitions
- VAT (value-added tax)
- A consumption tax charged as a percentage of the value of goods and services at each stage of the supply chain. Businesses collect it on sales and reclaim it on purchases, so only the value they add is effectively taxed. Called GST in many countries.
- Net price (VAT-exclusive)
- The price before VAT is added — the figure a business records as its own income. In Add VAT mode this is what you enter.
- Gross price (VAT-inclusive)
- The price with VAT already inside it — the total a consumer actually pays. In Remove VAT mode this is what you enter.
- VAT amount
- The tax itself: the gap between the net and gross prices. Added on top in Add VAT mode, or extracted from within the price in Remove VAT mode.
- Output VAT
- The VAT a registered business charges its customers on sales. It is collected on behalf of the tax authority, not kept as income.
- Input VAT
- The VAT a business pays on its own purchases and expenses. On a VAT return it is set against output VAT, so the business pays only the difference.
- Reverse VAT
- Working backwards from a tax-inclusive price to find the net and the VAT inside it. Done by dividing by one plus the rate — never by taking the rate off the gross.
- Effective VAT rate
- VAT measured as a share of the net total. It equals the headline rate unless a VAT-exempt charge such as exempt shipping is in the order, which pulls it below the nominal rate.
- VAT share of the total
- VAT as a fraction of the gross price. Always below the nominal rate — at a 20% rate the VAT is one sixth, about 16.67%, of the gross.
- Standard, reduced and zero rates
- Most systems have a standard rate, one or more lower reduced rates for essentials, and a zero rate on certain goods. Enter whichever applies to your supply.
- Zero-rated vs exempt
- Zero-rated supplies are taxed at 0% and the seller can still reclaim input VAT; exempt supplies carry no VAT but block input-VAT recovery. They look identical on a receipt but differ sharply for a business.
- Taxable base
- The amount VAT is calculated on: the net after any discount, plus fees that are themselves taxable. Discounts and VAT-exempt fees are excluded from it.
Good to know
What value-added tax actually is
Value-added tax, known as VAT in most of the world and as GST in places like Australia, Canada, India and New Zealand, is a tax on consumption. It is levied as a percentage of what goods and services sell for, and although a business hands the money to the government, the burden is designed to land on the final consumer. The clever part is in the name: tax is collected in slices, on the value added at each step of a supply chain, rather than all at once at the end. A timber merchant, a furniture maker and a shop each charge VAT on what they sell and reclaim the VAT on what they buy, so each effectively pays tax only on the margin it adds. By the time a table reaches a customer the full tax has been collected, but it has been gathered piece by piece along the way. This staged design is what makes VAT so widely used: it is hard to evade, because every business in the chain has a paper trail and an incentive to demand proper invoices from its suppliers, and it raises large, steady revenue without taxing income or savings directly. More than 170 countries now operate a VAT or GST, which is why a calculator that simply adds or removes the tax at any rate you choose is useful almost everywhere.
Net, gross and the VAT in between
Every taxed price can be read three ways, and confusing them is the most common source of error. The net price, also called the VAT-exclusive price, is the figure before tax — the amount a business counts as its own income. The gross price, or VAT-inclusive price, is the net plus the tax, and it is the total a customer actually pays. The VAT amount is simply the difference between the two. Which figure you start from depends on the setting. Prices quoted between businesses are usually net, because the buyer will reclaim the VAT and cares about the pre-tax cost; prices on a shop shelf or a consumer website are usually gross, because that is what the shopper will be charged at the till. Many countries legally require consumer prices to be shown gross for exactly this reason. The calculator's two modes mirror the two starting points: Add VAT begins from a net price and builds up to the gross, while Remove VAT begins from a gross price and works back down to the net. Get into the habit of asking, before you calculate anything, whether the number in front of you already includes the tax. A net of 1,000 and a gross of 1,000 describe two different deals — at 20% the first costs the customer 1,200 and the second only 833.33 net — so naming the figure correctly is half the battle.
Adding VAT, and the trap in removing it
Adding VAT is the easy direction. Take the net price, multiply by the rate, and add the result on top; at 20% a net of 1,000 gains 200 and becomes a gross of 1,200. You can do it in one step by multiplying the net by one plus the rate, so 1,000 times 1.20 is 1,200 directly. Removing VAT — recovering the net and the tax from a price that already includes them — is where people slip. The instinct is to take the rate straight off the gross, but that is wrong, and predictably so. The rate was applied to the smaller net figure, not the larger gross, so as a fraction of the gross the tax is always less than the headline rate. The correct method is to split the gross by the factor one-plus-the-rate. At 20%, a gross of 1,200 worked through 1.20 gives a net of 1,000, leaving 200 of VAT. Notice that 200 is one sixth of 1,200, about 16.67%, not 20%; taking a flat 20% of the gross would have given 240 and overstated the tax by a fifth. The shortcut for any rate is to use the fraction rate divided by one-hundred-plus-rate: 20/120 at 20%, 5/105 at 5%, 7/107 at 7%. Remove VAT mode applies the division for you, which is exactly what you need when filling in a return from a stack of gross receipts.
The family of VAT rates
A single country rarely has just one VAT rate. Most run a standard rate that applies to the bulk of goods and services, one or more reduced rates for things lawmakers want to keep affordable, and a zero rate for a narrow list of essentials. Standard rates vary widely around the world — commonly somewhere between the high teens and the mid-twenties as a percentage — while reduced rates might apply to food, children's clothing, books, public transport, domestic energy or medicines, depending entirely on local policy. Because the right rate depends on both the country and the specific product, there is no universal number a calculator could assume, which is why the rate is something you enter rather than something fixed. That flexibility is also what lets the tool double as a GST calculator or handle a historic rate, a proposed rate, or a neighbour's rate for comparison. The rate table built into the results leans on this: it reprices the same net base across a spread of common rates so you can see at a glance how much a few points either way changes the tax and the final price. When you are unsure which category a product falls into, the safest move is to check your tax authority's published rate list, because misclassifying a reduced-rate item as standard, or vice versa, is a frequent and avoidable mistake.
Zero-rated is not the same as exempt
Two categories produce a price with no VAT on it, and they are constantly confused because they look identical to a shopper, yet for a business they could hardly be more different. A zero-rated supply is genuinely taxable, just at a rate of zero per cent. Because it sits inside the VAT system, the seller can still reclaim all the input VAT it paid on its costs, which keeps those goods cheap right through the chain. An exempt supply, by contrast, is outside the VAT net altogether. No VAT is charged, but in return the seller usually cannot reclaim the input VAT on the costs of making that supply, so that tax becomes a real expense buried in the price. Financial services, insurance, education and certain property and health services are exempt in many systems. The practical upshot is that a business making zero-rated sales is in a happy position — it charges no tax but recovers its input VAT, often producing regular refunds — while a business making exempt sales bears unrecoverable VAT and may have to perform partial-exemption calculations to work out how much of its input VAT it can reclaim. This calculator treats a 0% entry as a zero rate on the price; whether a particular supply is zero-rated or exempt, and what that means for input-VAT recovery, is a classification question to settle with your tax authority.
How a business actually accounts for VAT
For a registered business, VAT is not a cost but a flow it administers on the government's behalf. Every sale carries output VAT, the tax charged to customers; every purchase carries input VAT, the tax paid to suppliers. At the end of each accounting period the business adds up both and pays the tax authority the difference: output minus input. When it has sold more than it has bought, it owes the balance; when it has bought more — a common position for exporters, zero-rated traders or a firm in a heavy investment phase — it reclaims a refund. This netting is the mechanism that makes VAT neutral for business and ensures the tax ultimately rests on the final consumer, who has no one to pass it on to. Good records are essential, because a valid tax invoice is the evidence that supports an input-VAT claim; without it, the reclaim can be denied. Some smaller businesses opt into simplified schemes — a flat-rate scheme that pays a fixed percentage of gross turnover instead of tracking every input, or cash accounting that defers the tax until invoices are actually paid — which trade some accuracy for less paperwork. This calculator works out the VAT on one price at a time; a VAT return is the same arithmetic repeated across every transaction and then summed, which is why keeping the per-sale figures straight is the foundation of getting the return right.
What the tax is really charged on
VAT is charged on the consideration for a supply, which sounds abstract but matters as soon as a price has more than one moving part. Discounts, fees, deposits and bundled extras can each change the amount that is actually taxed. A genuine discount offered before or at the time of sale reduces the taxable amount, so VAT is charged on the lower, post-discount price — which is why the calculator takes a flat discount off the net first and only then applies the rate. Delivery and service charges are trickier: in many systems they are treated as part of the same supply and follow the goods' VAT treatment, so they are taxed, but some charges are outside the scope or exempt. The tool lets you add a shipping or service fee and mark it taxable or exempt precisely so you can model the rule that applies, and it shows how an exempt charge raises the total without adding tax. Other wrinkles exist in real life — refundable deposits, gift vouchers, trade-ins and staff discounts each have their own treatment — but the core principle holds: identify the true taxable amount first, then apply the rate to that, never to a headline figure that still contains reductions or untaxed extras. Building the order up in the right order, net then discount then taxable fees, is what keeps the VAT honest.
Three honest ways to measure the tax
It is worth being precise about what a VAT percentage describes, because the same calculation yields three different rates and each answers a different question. The nominal rate is the headline figure you enter, defined against the net price — it is the rate the law sets. The effective rate measures the VAT against your net total, and in the ordinary case it equals the nominal rate exactly. It diverges only when an untaxed element is in the mix: add a VAT-exempt shipping charge, for example, and the net total grows while the tax does not, so the VAT as a share of the net falls a little below the headline. The third figure is the VAT's share of the gross — the tax divided by the total the customer pays — and this one is always lower than the nominal rate, because the tax is part of the larger total it is being compared against. At a 20% nominal rate the VAT is one sixth of the gross, about 16.67%; at 5% it is 5/105, about 4.76%. The calculator shows all three rather than picking one, because each is the right answer in a different setting: the nominal rate for quoting and compliance, the effective rate for spotting when exempt items are quietly changing the picture, and the share-of-total for understanding how much of a shelf price is really tax.
Registration and when you must charge VAT
Not every seller charges VAT. Whether you must depends on where you trade and how much you sell, and the rules differ sharply from country to country. Many systems set a registration threshold: once your taxable turnover over a rolling period passes a set figure, registration becomes compulsory and you must start charging output VAT, filing returns and, in return, gaining the right to reclaim input VAT. Below the threshold, registration is often voluntary — attractive to a business with large input VAT to recover or one that sells mainly to other registered businesses, less so to one selling to consumers who cannot reclaim the tax and would simply see higher prices. Other regimes have no threshold at all and require registration from the very first sale, and special rules frequently apply to non-resident or online sellers, who may have to register in a customer's country regardless of how little they sell there. Because registration brings both an obligation and a benefit, it is a genuine decision rather than a formality, and crossing a threshold mid-year can require quick action. This calculator helps you price a sale whether or not you are registered — model the gross a customer would pay with VAT added, or the net you would keep — but whether you are required to register, and from when, is a rule to confirm with your national tax authority.
Using this calculator well, and what it leaves out
The tool is a fast, exact engine for the core VAT arithmetic — net, tax and gross at any rate, in either direction, with discounts and fees layered on — and it is most useful when you respect that boundary. Start by naming your price: is the figure net or gross? Choosing the wrong mode is the single biggest cause of a wrong answer. Lean on Remove VAT mode whenever you are working back from a tax-inclusive total, since dividing by one plus the rate is the part people get wrong by hand. Use the rate comparison to size the effect of a rate change before it happens, and the save-and-compare feature to hold two pricing options side by side. Be aware of rounding: tax authorities differ on whether VAT is rounded per line or per invoice, so a total here can sit a fraction away from a line-by-line sum, and a formal document should follow your local rounding rule. And know the limits. The calculator does not decide which rate applies to your product, whether a supply is zero-rated or exempt, how cross-border place-of-supply or reverse-charge rules reassign the tax, or how partial exemption restricts input-VAT recovery — those are legal classifications, not arithmetic. Every figure it produces is an estimate to support a pricing or planning decision, not legal, tax, payroll or investment advice; for anything you will rely on, confirm the treatment of your specific supply with your tax authority or a qualified accountant.
Frequently asked questions
How do I add VAT to a price?
Multiply the net price by the VAT rate to get the tax, then add it on. At 20%, a net price of 1,000 gains 1,000 × 0.20 = 200 of VAT, for a gross of 1,200. Equivalently, multiply the net by 1 plus the rate (1,000 × 1.20 = 1,200) and the difference is the VAT. Choose Add VAT mode and the calculator does this and shows the VAT, net and gross together.
How do I find the VAT contained in a tax-inclusive price?
Split the tax-inclusive figure by the factor 1 + r — that is 1.20 at a 20% rate — to peel out the underlying net, and whatever is left over is the tax. So 1,200 ÷ 1.20 = 1,000 of net, leaving 200 of VAT. Choose Remove VAT mode for this reverse calculation; it is how you back out the tax when filling in a return or an invoice from a gross figure.
Why can't I just take the VAT rate off the gross price?
Because the rate is defined against the net, not the gross. The VAT was added to a smaller base, so it is a smaller fraction of the larger total. At 20% the tax is 20 ÷ 120 of the gross — one sixth, about 16.67% — not 20%. Taking 20% of a 1,200 gross gives 240, but the real VAT is 200. Always divide by one plus the rate instead.
What's the difference between VAT-inclusive and VAT-exclusive pricing?
A VAT-exclusive (net) price is shown before tax and VAT is added at the till — common in business-to-business pricing, where the buyer reclaims the VAT anyway. A VAT-inclusive (gross) price already contains the tax, which is what shoppers usually see on a shelf. Same supply, two ways of quoting it; the calculator's two modes match the two cases.
What's the difference between VAT and sales tax?
A retail sales tax applies only at one point — the very last step, when a finished item is sold to a shopper. VAT instead lands at every link in the supply chain, but because each registered business reclaims the tax on its own purchases, only the value it adds is taxed and the shopper at the end still carries the full amount. The price tag can look identical; the way the tax is collected is entirely different.
What is the effective VAT rate, and why might it differ from the headline rate?
The effective rate is the VAT measured against your net total. Normally it equals the rate you typed. It drops below that only when the order contains a VAT-exempt charge — for example exempt shipping — because that charge swells the net total without adding any tax. The calculator surfaces the effective rate whenever it diverges so the gap is never a surprise.
Is VAT charged on shipping and delivery?
Often yes. In many systems delivery is treated as part of the supply and follows the goods' VAT treatment, so VAT applies to it. But some carriage and certain services are outside the scope or exempt. The calculator lets you add a shipping or service fee and mark it taxable or exempt, so you can model whichever rule applies and see how it shifts the VAT and the effective rate.
How does a discount affect the VAT?
A genuine discount given before the sale reduces the amount VAT is charged on. The calculator takes a flat discount off the net subtotal first, then applies VAT to what remains, so the tax falls in step with the price. If a discount is larger than the net price it is capped — the taxable base cannot go below zero — and the result flags it.
What's the difference between zero-rated and exempt supplies?
Both mean no VAT is added to the price, but they part ways behind the scenes. A zero-rated supply is taxed at 0% and the seller can still reclaim the input VAT on its costs. An exempt supply carries no VAT and the seller generally cannot reclaim input VAT, which makes its purchases more expensive. For a buyer the receipt looks the same; for a business the distinction matters a great deal.
What is input VAT and output VAT?
Output VAT is the tax a registered business charges customers on its sales. Input VAT is the tax it pays on its own purchases. On each VAT return the business subtracts input from output and pays the tax authority the difference, or reclaims a refund when inputs exceed outputs. This calculator works out the VAT on a single price; your return totals it across every transaction in the period.
Do I have to register for VAT?
It depends on where you trade and how much you sell. Many countries require registration once taxable turnover passes a threshold, and some require it from the first sale or for non-resident sellers. Registration lets you reclaim input VAT but also obliges you to charge output VAT and file returns. This tool helps you price either way; whether you must register is a rule to confirm locally.
Which VAT rate should I use?
Use the rate your jurisdiction sets for the specific good or service. Most systems have a standard rate, lower reduced rates for things like food, books or energy, and a zero rate for a short list of items. Rates also vary by country, so a cross-border sale may use the buyer's rate. The rate is an input here precisely because it changes so often — enter the one that applies and compare neighbours with the rate table.
How is VAT handled on imports and cross-border sales?
Goods crossing a border usually attract import VAT, charged on the value plus any duty and freight, which a registered importer can often reclaim. For services and digital sales the place-of-supply rules and reverse-charge mechanism can move the obligation to the buyer's country. This calculator covers the core net-VAT-gross arithmetic; for the landed cost of an import or a tourist refund, use the dedicated import and VAT-refund tools.
Does this calculator give legal or tax advice?
No. It is an estimating and pricing tool. VAT law is detailed and country-specific — what is taxable, at what rate, and who must account for the tax all vary — and the rules change. Treat every figure as an estimate to support a decision, and confirm the treatment of your particular supply with your national tax authority or a qualified accountant before you rely on it.
How accurate are the figures, and does rounding matter?
The maths is exact; the only wrinkle is rounding. Many tax authorities let you round VAT per line or per invoice, and a fraction of a unit can differ depending on which rule you follow. The calculator keeps full precision and displays rounded figures, so a total may sit a hundredth away from a line-by-line sum. For a formal invoice, apply your jurisdiction's rounding rule to the displayed numbers.
