This is an estimate based on a constant expected return. Mutual funds are market-linked — actual returns vary year to year and are not guaranteed. This is not investment advice.

How to use the SIP calculator

  1. Keep the mode on SIP (monthly) and enter how much you'll invest each month.
  2. Enter the expected annual return — 10–12% is a common long-term assumption for equity funds.
  3. Enter your investment period in years.
  4. Read your future value, total invested and estimated gains. Switch to Lumpsum for a one-time investment.

How SIP returns are calculated

A SIP (Systematic Investment Plan) invests a fixed amount every month, and each instalment compounds until maturity. The future value uses FV = P × ((1+i)ⁿ − 1) ÷ i × (1+i), where P is the monthly amount, i is the monthly return (annual ÷ 12) and n is the number of months. Because early instalments compound the longest, staying invested for more years is where most of the growth comes from.

SIP vs lumpsum

A lumpsum invests a single amount today and grows as FV = P × (1+r)ⁿ over n years. Lumpsum can work well when you have a large sum ready and markets are favourable, while SIP spreads your entry across market ups and downs (rupee-cost averaging) and suits regular savers. Use the toggle above to compare both.

Frequently asked questions

Are SIP returns guaranteed?

No. Mutual funds are market-linked. The calculator uses a constant expected return to project a figure, but real returns rise and fall each year and can be higher or lower.

What return percentage should I use?

Many long-term investors model equity SIPs at around 10–12% per year and debt funds lower. Use a realistic, slightly conservative number rather than the best historical year.

Are my numbers sent anywhere?

No. Everything is calculated in your browser; nothing you enter is uploaded or stored.
