How the lumpsum calculator works

A lumpsum (also written lump sum or "lum sum") investment puts the full amount to work on day one. Returns compound each year - you earn interest on interest. This lumpsum return calculator uses the standard future-value formula used for mutual funds, FDs and other one-time investments.

Lump sum investment formula
Future value (FV) = P × (1 + r)n
P = principal (lumpsum amount)  •  r = expected annual return  •  n = years
Wealth gained = FV - P  •  Absolute return = (FV - P) / P

Example: ₹5,00,000 at 12% for 10 years → 5,00,000 × (1.12)10 ≈ ₹15,52,924. Change the inputs above to match your amount, rate and tenure.

Compare the same money as monthly SIPs with the lumpsum vs SIP calculator, or model later withdrawals with the SWP calculator.
