Lumpsum Calculator

How the Lumpsum Calculator works

• A lumpsum investment puts a one-time amount into a fund, stock, or other asset and leaves it to grow.
• Growth is modelled with compound interest: each year’s return builds on prior gains.
• Lumpsums work best with a clear horizon and an emergency fund already in place.
• If you are uneasy about market timing, stagger entry via a Systematic Transfer Plan (STP).

FV = P × (1 + r)^t, where P is principal, r is annual return, t is years.

Example: ₹5 lakh invested for 10 years at 12% p.a.

Estimated value ≈ ₹15.5 lakh. Invested amount stays ₹5 lakh; compounding contributes ≈ ₹10.5 lakh — showing why idle cash in low-yield accounts can be costly over long horizons.

Practical tips

• Match asset allocation to the goal date — do not put near-term money fully in equities.
• For large windfalls, consider deploying over 3–6 months via STP into equity funds.
• Rebalance annually so one asset class does not dominate the portfolio.
• Factor in taxes: equity LTCG and debt taxation rules affect net returns.

Frequently asked questions

When is lumpsum better than SIP?

When you already hold surplus cash and have a long horizon. SIPs are better when money arrives monthly.

Should I wait for a market dip?

Timing consistently is hard. A staggered STP often beats waiting indefinitely in cash.

Are calculator returns realistic?

They are illustrations only. Past fund returns do not guarantee future results.
