Work out lumpsum investment return instantly with clear inputs, formula shown and shareable results.
A lump sum compounds for the entire period, so the outcome is driven by the rate and, more powerfully, by time. Each extra doubling period matters more than the last because it works on a larger base.
Compound growth
FV = P(1 + r)^t; doubling time = ln2 / ln(1+r)
Figures are estimates for planning only. Market returns are not guaranteed, and rates, limits and tax rules change. This is not financial or tax advice — speak to a qualified adviser before acting.
Historically a lump sum wins on average because money is invested sooner, but a SIP reduces the risk of a badly timed entry.
How long the money takes to double at the given rate — a quick sanity check on any return assumption.
