Lumpsum Calculator India - Compound Interest Calculator

Calculate your one-time investment growth instantly. Lumpsum future value = P x (1 + r/12)^(12 x n), where P is the amount invested, r is the annual return and n is the number of years. For example, Rs 1 lakh at 12% for 10 years grows to about Rs 3.3 lakh (Rs 1 lakh invested + Rs 2.3 lakh gains). This free tool shows a year-by-year growth table, return sensitivity and inflation-adjusted value. Investments are subject to market risks - read all scheme related documents carefully.

Higher expected returns usually mean more volatility - a 15% assumption is aggressive, 10% is conservative.

❓ Lumpsum Calculator FAQ
How is a lumpsum return calculated?

Lumpsum growth uses compound interest: A = P x (1 + r/n)^(n x t), where P is the one-time amount, r the annual return and n the compounding frequency. This calculator compounds monthly (n = 12), matching how mutual funds and FDs accrue interest.

What return rate should I assume?

For equity mutual funds, 10% (conservative), 12% (moderate) and 15% (aggressive) are standard. The Nifty 50 has returned about 12-13% annualized over 15+ years. For fixed deposits use the current FD rate, usually 6-7%. Past performance does not guarantee future returns.

Is a lumpsum investment taxable?

Gains are taxed at redemption: LTCG (held > 12 months) at 12.5% above Rs 1.25 lakh/year; STCG at 20%. FD interest is added to your income and taxed at your slab rate. The invested principal itself is never taxed.

Lumpsum vs SIP: which is better?

A lumpsum wins in a steadily rising market because the full amount compounds from day one, but carries timing risk. A SIP averages your cost across cycles and enforces discipline. Most advisors suggest SIPs for salaried investors and lumpsums for surplus cash.

How much will Rs 1 lakh become in 10 years?

At 12% compounded monthly, Rs 1 lakh becomes about Rs 3.3 lakh in 10 years. At 10% it becomes about Rs 2.7 lakh, and at 15% about Rs 4.4 lakh. Adjust the sliders above for your exact numbers.
