Investment Calculators
Compound growth, SIPs, future value, returns and investment planning.
Investment mathematics is mostly one idea — compound growth — viewed from different angles. The Compound Interest Calculator is the reference tool: it shows how a starting amount and regular contributions grow, and splits the result into what you put in versus what compounding added. The Investment Calculator builds on that with inflation adjustment, so you can see results in today's purchasing power. The SIP Calculator applies the same engine to monthly systematic investment plans, including annual step-ups.
The remaining tools answer planning questions: future value ("what will this be worth?"), present value ("what is a future amount worth today?"), and ROI ("what did this investment actually return, annualized?"). Every calculator states its compounding assumptions explicitly and shows the year-by-year table behind the headline number.

A note on return assumptions
Every projection here is driven by the return rate you enter, and real-world returns are neither fixed nor guaranteed. A sensible way to use these tools is to run three scenarios — conservative, expected and optimistic — and check that your plan survives the conservative one. The scenario comparison feature on each calculator exists for exactly this. Historical long-run averages for diversified equity portfolios are often quoted between 6% and 10% per year before inflation, but past performance does not determine future results, and these pages never assume otherwise.
