Free Calculators for Mutual Fund Investors
Eleven tools, no signup, nothing stored. Every projection runs on an assumption you supply, because nobody can tell you what a market-linked investment will do.
What a calculator can and cannot tell you
Most of these tools take a return rate as an input. That is deliberate and it is the honest way to build them. Nobody knows what a market-linked investment will do over the next fifteen years, so a calculator that hands you a confident number has simply assumed one on your behalf and then hidden the assumption.
So the useful way to use any of them is twice. Once at the rate you expect, and once several percentage points lower. If a plan still works in the second run, it is funded by your saving. If it only works in the first, it is funded by an assumption, and that is worth knowing while you can still do something about it.
The one tool here that measures rather than projects
The XIRR calculator is different from the rest. It does not project anything; it takes cashflows that already happened and works out the annualised return your money actually earned, accounting for the date of every instalment.
That matters because the figure most apps show is absolute return, which ignores time completely and therefore misstates a SIP badly. Our guide on reading a mutual fund statement explains which number on your statement is worth reading and which one to ignore.
What none of these include
- Tax. Explained structurally, without rates that change every year, on our page about mutual fund taxation.
- Exit load, which is counted per purchase and catches SIP investors in particular, as our guide on exit load sets out.
- The expense ratio, the one cost that is knowable in advance and never appears on a statement. See expense ratio.
- The order in which returns arrive, which matters enormously once you are withdrawing monthly and which no single-rate model can represent.
We are an AMFI-registered mutual fund distributor (ARN-145870) working since 2014, not investment advisers, and none of these tools is a recommendation. If you would like the numbers worked through against your own situation instead of round figures, get in touch — that conversation costs nothing.
