Compounding is the whole game, and small differences in rate or time period produce large differences in outcome. These investment calculators let you test that before your money is committed. The compound interest calculator shows how a lump sum grows at different compounding frequencies, the SIP calculator projects the maturity value of a monthly mutual-fund plan, and the FD calculator handles fixed-deposit maturity for any tenure.

How to choose the right calculator
To measure results rather than project them, the ROI calculator gives a simple percentage return and the CAGR calculator annualizes it so you can compare investments of different lengths on equal terms. Every projection here depends on an assumed return — treat 10–12% for equity and 6–7% for debt as planning inputs, not guarantees, and re-run the numbers with a lower rate to see how sensitive your plan is.
Frequently Asked Questions
For long-term equity mutual funds, 10–12% per year is a common planning assumption; for debt funds and fixed deposits, 6–7%. These are estimates, not promises. Always model a conservative case as well.
ROI is the total percentage gain over the whole holding period. CAGR converts that into a smoothed annual rate, which lets you compare a 3-year investment against a 7-year one fairly.
No. It assumes a constant annual return for simplicity. Real returns vary year to year, so use the result as a directional estimate and review it as markets move.
