Lumpsum Calculator
Estimate the future value of a one-time investment.
How this works
Future value = P × (1+r)n, where P is the invested amount, r is the annual rate of return, and n is the number of years — assuming annual compounding. Actual investment returns are never guaranteed; the rate here is an assumption you supply.
Frequently asked questions
Does this compound monthly or annually?
Annually, for simplicity. For monthly compounding on a lumpsum, use the Compound Interest Calculator instead with a 12x/year frequency.
Is this the same as a Fixed Deposit calculator?
The math is similar (compound growth), but FDs usually have bank-fixed rates and TDS considerations this tool doesn't model.
