How SIP and Compound Growth Calculations Work
Understand recurring contributions, compounding, assumed returns, and why calculator projections are not promises.
Separate contributions from returns
A SIP or compound-growth result depends on the starting amount, recurring contribution, return assumption, compounding interval, and time. Check whether contributions occur at the beginning or end of each period because that changes the result.
Use realistic scenarios
Market returns are uneven, while calculators commonly apply a smooth rate. Compare several rates and time horizons instead of treating one projection as a forecast. Fees, taxes, inflation, and missed contributions reduce real outcomes.
Read the result correctly
Distinguish total money contributed from estimated growth and nominal ending value. For long plans, also consider purchasing power. Use regulated professional advice for decisions that depend on personal risk, tax, or retirement circumstances.
