Lumpsum Calculator

See what a one-time investment can grow to over time, how long it takes to double, and the monthly SIP that would reach the same amount.

How to use it

  1. Enter the amount you invest once.
  2. Set the yearly return you expect and the number of years.
  3. Compare it with the SIP that gives the same result.

How it is calculated

Future value = P x (1 + r)^n, where P is the amount invested, r the yearly return and n the number of years.

Frequently asked questions

What will Rs 1 lakh become in 10 years?

At a 12% yearly return, about Rs 3.1 lakh.

How long does money take to double?

Divide 72 by the yearly return. At 12% money doubles in about 6 years.

Is lumpsum better than SIP?

A lumpsum invested early can earn more if markets rise, while a SIP spreads the risk of investing at a high point. The right choice depends on when you have the money.

Are returns taxed?

Equity fund gains above Rs 1.25 lakh a year held over one year are taxed at 12.5%. Debt fund gains are taxed at your slab rate.
