Lumpsum Calculator — One-Time Investment Returns Calculator 2026
Calculate how much your one-time lumpsum investment will grow using compound interest. Perfect for mutual funds, fixed deposits, stocks, or any investment with compounding returns.
The Power of Lumpsum Investing
A lumpsum investment of ₹5 lakhs at 12% for 20 years grows to ₹48+ lakhs — nearly 10x your money! The key is time in the market. Long holding periods dramatically amplify compound interest.
When to Invest Lumpsum
- When markets have corrected significantly (buy the dip)
- When you receive a bonus, inheritance, or windfall
- For stable instruments like FDs (no market timing needed)
- Combine with SIP: lumpsum now + monthly SIP for best results
Frequently Asked Questions
What is Lumpsum Investment?
Lumpsum means investing a large one-time amount in mutual funds, stocks, or other instruments. Unlike SIP (monthly), you put all money at once and let it compound over time.
Lumpsum vs SIP — which is better?
Lumpsum gives higher returns if markets are at a low point (you buy cheap). SIP is safer because it averages your cost. For volatile markets, SIP wins. For stable/rising markets, Lumpsum wins.
What is the Rule of 72?
A quick estimation: divide 72 by the annual return rate to find how many years it takes to double your money. At 12% returns, money doubles in ~6 years (72/12=6).
Is 12% return realistic for lumpsum?
For equity mutual funds over 7-10+ years in India, 12-15% CAGR is historically achievable. Short-term returns can be highly volatile. FDs give 6-7%, debt funds 7-8%.
How is compound interest calculated?
Future Value = Principal × (1 + Rate/100)^Years. Interest is earned on both the original amount and accumulated interest — that's the magic of compounding.
