One-time lumpsum mutual fund investment calculator. Models long-term compounding returns, future maturity corpus, and wealth multipliers across customizable annual expected growth rates.
Runs entirely in your browser
A lumpsum investment is a single upfront amount left to grow, in contrast to regular contributions. This calculator projects what a one-time investment becomes over time at a chosen expected annual return, showing the maturity corpus, the total gain, and the wealth multiplier — how many times your money grew.
It is the clearest illustration of compounding on a fixed sum: with no further contributions, all the growth comes from the return compounding on itself, so time and rate are everything. Comparing a lumpsum projection against a regular-investment (SIP) plan for the same total shows the trade-off between investing all at once and spreading it out.
It runs in your browser, so your figures stay private. The projection assumes a constant return, but real market returns vary and are not guaranteed, so use it to understand compounding and compare scenarios.
