Frequently Asked Questions
What is a lumpsum investment?
A lumpsum investment is a one-time, large investment made all at once, as opposed to periodic investments like SIP. It is ideal when you have a significant amount ready to deploy.
How is lumpsum return calculated?
The formula is: A = P × (1 + r)^t, where P is the principal, r is the annual return rate, and t is the number of years. Our calculator applies this to show year-by-year growth.
Is lumpsum or SIP better?
Lumpsum works better when markets are at a low point and expected to rise. SIP is better for volatile markets as it averages your purchase cost. If you have a large idle amount, lumpsum often delivers higher returns in bullish markets.
What return rate should I assume?
For equity mutual funds in India, historical long-term returns are 12–15%. For debt funds, 6–9% is typical. Index funds have historically delivered 10–12% over long periods.
Can I use this for FD or debt fund calculations?
Yes. Simply enter the FD or debt fund rate of return. For FDs, use the annual interest rate offered by your bank.
Is lumpsum investing risky?
Timing risk is the primary concern — if markets fall after a lumpsum investment, the impact is immediate. Unlike SIP, you don't benefit from rupee-cost averaging over volatile periods.
