Lumpsum Calculator
Four calculators in one — future value, goal planner (present value), required rate of return and required time. Choose a compounding frequency and currency, factor in inflation and tax, and download a branded ASLI FORM report.
Year-by-Year Growth

Notes & Assumptions
- Future value uses compound interest: FV = P × (1 + r/m)^(m·n); m = compounding periods per year.
- The effective annual rate (CAGR) = (1 + r/m)^m − 1; this is what the Rule of 72 uses.
- A yearly top-up (if set) is added at the start of each year and grows with the same effective rate (annuity-due).
- Real (inflation-adjusted) value = FV ÷ (1 + inflation)^n; real rate uses the Fisher equation.
- Tax on gains, if entered, is applied to total gains to show a post-tax maturity (actual tax depends on instrument & jurisdiction).
- Returns are illustrative and not guaranteed; market-linked instruments vary. This is not investment advice.
Lumpsum Across Instruments (indicative)
See how the same lumpsum grows across common instruments at indicative rates. Labels adapt to your selected currency. Non-guaranteed instruments are market-linked estimates.

What is a Lumpsum Investment?
A lumpsum investment is a one-time deposit of capital that grows over time through compounding. Unlike a SIP (periodic instalments), the entire amount is deployed at once, so it starts earning returns immediately. The future value is given by FV = P × (1 + r/m)^(m·n).
- Power of CompoundingInterest earns interest; longer tenures amplify growth exponentially.
- Compounding FrequencyMonthly/daily compounding yields a higher effective rate than yearly at the same nominal rate.
- Time in the MarketStarting earlier matters more than the amount — time is the biggest multiplier.
- Inflation AwarenessAlways compare returns against inflation to know your real purchasing power.
Compounding Frequency Guide
The same nominal rate produces different effective returns depending on how often interest is compounded. Effective annual rate = (1 + r/m)^m − 1.
- Yearly (m=1)Interest credited once a year; effective rate = nominal rate. Common in PPF.
- Half-Yearly (m=2)Twice a year; slightly higher effective yield.
- Quarterly (m=4)Four times a year; common for bonds/FDs.
- Monthly (m=12)Twelve times a year; common for FDs and savings.
- Daily (m=365)Near-continuous compounding; the highest effective yield for a given nominal rate.
Rule of 72 & Lumpsum vs SIP
- Rule of 72Years to double ≈ 72 ÷ annual return. At 8% → ~9 yrs; at 12% → ~6 yrs.
- LumpsumBest when you have a surplus and markets are reasonably valued; whole amount compounds from day one.
- SIPRupee-cost averaging and discipline; ideal for salaried, periodic cash flows and volatile markets.
- Hybrid (STP)Park a lumpsum in debt and systematically transfer to equity — combines both approaches.
