Lump-sum Investment Calculator
Estimate the future value of a one-time lump-sum investment.
Assumptions used in this calculation
- Return assumption: Assumes a constant annual return rate for the full period; actual market-linked returns vary.
About this calculator
A lump-sum investment starts compounding on day one, so estimating its future value accurately requires raising your principal to the power of the number of years invested, arithmetic that gets unwieldy fast for anything beyond a handful of years, and impossible to sanity-check by hand once fractional rates are involved. This calculator applies A = P × (1 + r)^t to your investment amount, expected annual return and holding period, and returns the exact projected maturity value along with a year-by-year growth chart. It's the tool to use whenever you're deploying money all at once, an inheritance, bonus, or matured deposit, rather than investing it in installments, and it makes it easy to see how sensitive the outcome is to small changes in either the assumed return rate or how many extra years you stay invested, since both compound multiplicatively rather than linearly.
Worked example
₹5,00,000 for 10 years at 10% expected return
Result: Maturity value ≈ ₹12,97,000
