What is a Lumpsum vs SIP?

If you have a large sum to invest — from a bonus, inheritance, property sale, or maturity proceeds — should you invest it all at once (lumpsum) or spread it out monthly through a SIP? This calculator compares both approaches for the same total investment amount and shows you the projected outcomes.

Historically, lumpsum tends to outperform because markets trend upward over time and your money is fully invested from day one. However, SIP reduces the risk of investing at a market peak through rupee-cost averaging. The right choice depends on market conditions, your risk tolerance, and whether the money is available upfront or earned monthly.

When to Use This Calculator

  • Deciding how to invest a ₹10 lakh bonus — all at once or spread over 12 months
  • Comparing outcomes when inheriting a lump sum or receiving maturity proceeds
  • Understanding the opportunity cost of waiting to invest via SIP
  • Making a case for lumpsum investing when markets have corrected
  • Planning investment of property sale proceeds or insurance payouts

Key Terms

Lumpsum Investment

Investing the entire amount in one go. The full amount starts compounding immediately, which is advantageous in rising markets.

Systematic Transfer Plan (STP)

A middle-ground approach where you park the lump sum in a liquid/debt fund and auto-transfer a fixed amount to equity fund monthly. Combines safety with gradual equity exposure.

Time in Market

The principle that staying invested longer matters more than timing the market. Supports lumpsum investing because more of your money is in the market for longer.

Frequently Asked Questions

Is lumpsum or SIP better for equity mutual funds?+
Data shows lumpsum outperforms SIP about 65-70% of the time over 10+ year periods because markets trend upward and more money is invested for longer. However, SIP is psychologically easier and protects against the worst-case scenario of investing everything at a market peak.
I have ₹10 lakh to invest. What should I do?+
If you have a 10+ year horizon and can handle short-term volatility, lumpsum into an index fund is statistically optimal. If you're risk-averse or markets seem overvalued, use an STP — park in a liquid fund and transfer to equity over 6-12 months. This gives you partial averaging without sitting on idle cash.
Does this calculator account for market volatility?+
This calculator uses a constant annual return rate, which represents the average return over the period. Real markets are volatile — lumpsum returns depend heavily on entry timing. For a more realistic picture, the assumed return rate already factors in long-term averages.
What about tax implications?+
Both approaches are taxed the same way on redemption — LTCG at 12.5% above ₹1.25L for equity (held >1 year) and at slab rate for debt. With SIP, each installment has its own purchase date, so LTCG eligibility is calculated per installment. This doesn't significantly favour one over the other.
