About this tool
This calculator projects a single lump sum investment using annual compounding: future value = amount times (1 + r) raised to the power of t, where r is the annual return and t is the number of years. No further money is added, so all growth comes from the original amount compounding year after year.
Frequently asked questions
How is this different from a SIP calculator?
A lump sum calculator grows one payment made today, while a SIP calculator grows many monthly payments. Use this one when the money is invested all at once.
What if the return changes over time?
The calculator assumes one steady rate for the whole period, so the result is an estimate. Real investments rarely grow at exactly the same rate every year.
