About the Lumpsum Calculator

A lump sum investment compounds on itself from day one, with no further contribution. Over long periods the effect is dramatic: at 12%, money doubles roughly every six years, so ₹5 lakh becomes about ₹15.5 lakh in a decade.

The risk is entry timing. Putting a large sum into equity just before a correction can take years to recover, which is why large amounts are often staggered over several months through a systematic transfer plan.

The formula

FV = P × (1 + r)^n
PAmount invested
rAnnual rate of return
nYears

Assumes annual compounding of returns with no withdrawals along the way.

Things worth knowing

1
For large amounts into equity, use a systematic transfer plan over 6–12 months to spread the entry.
2
The rule of 72 gives you a quick doubling estimate: 72 ÷ return = years.
3
Match the horizon to the asset. Money you need within three years does not belong in equity.

Frequently asked questions

Future value = P × (1 + r)^n, where P is the amount invested, r the annual return and n the number of years. Returns compound annually with no withdrawals.

If the money is already in hand and the horizon is long, a lump sum has historically done slightly better because it is invested longer. A SIP or systematic transfer reduces the risk of entering at a peak, which matters more for large amounts.
