Yes. The opening lump sum and the recurring contribution (the SIP) run together in the same projection: the lump sum compounds from day one, while each periodic deposit compounds only for the time left after it is paid in. Set the SIP to zero to model a pure lump-sum purchase, or drop the opening balance to nothing to model a plan funded purely through contributions. The default scenario blends both, with $10,000 invested upfront and $500 added every month for 15 years.

The expense ratio is the fund's total internal running cost, deducted continuously from assets every year for as long as you hold it, so it quietly lowers your return whether the fund rises or falls. The loads are one-off sales charges levied on a transaction: a front-end load is taken when you buy, while the back-end and exit loads are taken when you sell. In short, the expense ratio is a recurring drag on the balance, and the loads are entry or exit tolls. A clean no-load index fund may carry no loads at all yet still has an expense ratio.

A front-end load is skimmed off every purchase, so a 5% front-end load means only $23,750 of a $25,000 cheque actually buys units. The back-end load (a contingent deferred sales charge) and the exit load are charged when you redeem, but only if you sell inside their stated windows, measured in years from purchase. Hold past the end of both windows and they fall to zero, which is why a normal full-term buy-and-hold pays no redemption load at all. In the early-redemption example, selling after 3 years triggers the 1% back-end load because 3 years is inside its 5-year window ($250), while the 1% exit load costs nothing because 3 years already sits beyond its 1-year window.

Because the 1% is charged every year on your whole balance, and the money it removes can never compound again. Each annual slice looks small, but skimming it year after year robs you of all the growth that money would otherwise have produced over the rest of the horizon, so the lifetime cost snowballs well beyond the headline rate. On the default 15-year plan, a 1% expense ratio builds up to an expense-ratio drag of about $23,260, far larger than 1% of any single year's balance. The longer you stay invested, the more lopsided that drag becomes.

Part of a fund's total return is handed back as distributions, sized by the dividend yield. With DRIP (reinvest) switched on, those distributions automatically buy more units at no sales charge, so they stay inside the fund and keep compounding. With payout switched on, the NAV grows on price appreciation alone and the distributions land outside the fund as cash, which is the dividend income you pocket along the way and which can be taxed as income as it arrives. The toggle therefore decides whether your dividends are reinvested for growth or collected as a running cash stream.

Whether a slice of total return is labelled a dividend or left as price growth, reinvesting it puts the same money straight back to work in the fund. So under DRIP the fund compounds at the full net return no matter how that return is split between appreciation and distributions, and the dividend yield becomes invisible in the final fund value. The reinvested-dividends figure (about $20,620 in the default plan) tells you how much of the ending balance arrived through distributions, but nudging the yield up or down while keeping total return fixed leaves the DRIP fund value unchanged. The split only starts to matter once you switch to payout, where distributions leave the fund instead of compounding within it.

They describe two different things. The net annual fund return is what the fund earns each year after its expense ratio (a 10% gross return less a 1% expense ratio leaves 8.9%), and it applies to every dollar for as long as that dollar stays invested. The overall annualized return is instead the growth rate of your whole pot: the single rate that turns the total $100,000 you paid in into the final $217,734 over 15 years, which comes out at about 5.32%. It sits below the fund's own 8.9% because your contributions arrived gradually rather than all on day one, so the pooled total had time to grow only a smaller multiple. A single lump sum left untouched from the start would close the gap between the two figures.

Load fee impact is the total dollar amount taken by the sales loads, adding together any front-end, back-end and exit charges; in the early-redemption example it is $1,500, made up of $1,250 at purchase plus a $250 back-end charge. Expense-ratio drag is the lifetime dollar cost of the expense ratio plus any advisory fee across the whole horizon, and it is deliberately larger than the headline percentage because it also counts the compounding you forfeited on every dollar those annual fees removed. Together they separate the one-off transaction costs from the recurring cost of simply owning the fund.

The forward mode projects your final fund value from the inputs you enter. The reverse modes instead fix a target fund value and back-solve for one missing piece: the SIP you would need, the opening lump sum required, the annual return the plan demands, or the holding period it would take. The sixth, present value, discounts a single future fund value to what it is worth today. For instance, reaching $250,000 in 15 years alongside the $10,000 starting amount needs about $589 a month, or roughly $18,981 upfront beside a $500 SIP, while the present value of that $250,000 due in 15 years is about $69,586.

Two taxes are optional. A capital-gains tax is applied to the fund's gain when you redeem, and an income tax is applied to dividends only when they are actually paid out to you as cash. To keep things simple, reinvested (DRIP) dividends are treated as untaxed until redemption, as if the fund sat inside a tax-deferred wrapper, so a payout plan can carry more annual tax than a reinvesting one. These figures are estimates that ignore brackets, allowances, holding-period rules and local law, and they are not tax advice; check your own circumstances with a qualified professional.

The nominal fund value is the headline balance expressed in the currency of the final year, while the real fund value re-expresses that same balance in present-day money so you can judge what the ending sum could genuinely buy. Because prices tend to climb, the real figure lands beneath the nominal one, and that shortfall grows wider over a longer horizon. In the default 15-year plan the $217,734 nominal balance is worth about $150,338 in today's purchasing power after 2.5% inflation.

Inflation never touches the fund's growth itself; it is applied afterwards as a separate discount that translates the nominal balance into today's money. The calculator takes the final fund value and deflates it by your inflation rate compounded over the holding period, which is what produces the real value shown beside the headline figure. Raising the inflation assumption lowers the real value while leaving the nominal projection exactly where it was.

The sensitivity view recomputes the outcome across a band of return assumptions, usually a few percentage points on either side of the rate you entered, so you can see how heavily the result leans on a figure no one can know in advance. Because returns compound over many years, a swing of a couple of points moves a long-horizon fund value sharply, which is a healthy guard against treating any one projection as a promise. The middle line is your best single estimate; the surrounding spread is the range a sensible plan should be able to survive.

Yes. The mathematics is entirely currency-neutral, since percentages, ratios and compounding behave identically whatever the unit of money happens to be. Choosing a different currency changes only how the figures are displayed and formatted, not how they are calculated, so you can run the same plan in dollars, euros, pounds, rupees or yen and read it back in familiar symbols.

Yes. You can store any projection as a named scenario and keep several beside one another to compare different funds, contribution levels or holding periods at a glance. Every calculation also has a shareable deep link that encodes all of your inputs, so opening it reproduces the exact result on any device, which makes it easy to send a plan to a partner or an adviser.

Treat them as careful estimates rather than guarantees. The model assumes a single, constant annual return, whereas real fund returns arrive unevenly and vary from one year to the next, and the tax treatment is simplified, including the assumption that reinvested dividends defer tax until redemption. It also depends on the cost and yield figures you supply, so its accuracy is only as good as those inputs. Use the output to compare plans and understand the levers, not as a forecast of any particular fund's performance.

The fees are stacked multiplicatively rather than simply added up. The calculator takes your gross return, strips out the expense ratio, then strips out any separate advisory or wrap fee, so the net annual return is (1 + gross) × (1 − expense ratio) × (1 − advisory) − 1. The advisory fee sits on top of the expense ratio because it pays an outside manager rather than the fund itself. With a 10% gross return, a 1% expense ratio and no advisory fee, that works out to a net 8.9% a year.

The fund value is the balance still invested, before you sell; the net proceeds are what actually reaches you once any redemption load and capital-gains tax are removed at the exit. On a normal full-term hold there are no redemption loads, so the two differ only by tax. On an early sale they can separate sharply. Take the fee-heavy example: $25,000 goes in, but a 5% front-end load means only $23,750 ever buys units, a 1.5% expense ratio plus a 0.5% advisory fee weigh on the balance across all three years, and a $250 back-end load applies on the way out because three years still sits inside the five-year CDSC window. The exit load is $0, since three years has already cleared its one-year window, and this particular scenario applies no capital-gains tax at all. Once the loads are taken out — $1,500 of sales charges in total — the net proceeds come to about $29,509. Net proceeds are the honest "what you walk away with" figure.
