Lumpsum vs SIP — which is better?

Lumpsum delivers higher returns when markets are at a low or rising. SIP performs better in volatile or correcting markets due to rupee-cost averaging. For most retail investors, SIP is safer; lumpsum suits experienced investors with market timing conviction.

What is a realistic return rate for lumpsum?

Indian equity mutual funds have historically delivered 11%-14% CAGR over 10+ year periods. Debt funds yield 6%-8%. Use 12% as a conservative equity assumption for long-horizon planning.

How is lumpsum taxed in India?

Equity fund LTCG above ₹1.25 lakh per year is taxed at 12.5%; STCG (<12 months) at 20% under FY 2025-26 rules. Debt fund gains are taxed at your slab rate.

Can I withdraw lumpsum anytime?

Yes for open-ended funds, subject to exit load (usually 1% if redeemed within 12 months). ELSS lumpsum has a 3-year lock-in. Closed-ended and FMP funds are illiquid until maturity.

What is a Lumpsum Investment?

A lumpsum investment means putting a one-time sum of money into a mutual fund instead of investing monthly via SIP. It's a popular choice when you receive a bonus, inheritance, FD maturity, or any windfall, and want the full amount working for you immediately.

With equity mutual funds, lumpsum can deliver superior returns over long horizons due to uninterrupted compounding. The risk: if you invest at a market peak, you may underperform an equivalent SIP that benefits from rupee-cost averaging.

How the Calculation Works

The calculator uses the standard compound interest formula:

FV = P × (1 + r)ⁿ

P = principal (your one-time investment)
r = expected annual return (e.g. 0.12 for 12%)
n = investment period in years

Example: ₹1,00,000 invested for 10 years at 12% p.a. grows to ≈ ₹3,10,585 — a gain of ₹2,10,585.
