Goal SIP Calculator

Work out the exact monthly SIP you need to reach a financial goal — like a house, education, or retirement corpus — by your target date.

Frequently Asked Questions

How does a goal SIP work?

You set a target amount and time horizon, and the tool works backward from the SIP maturity formula to find the monthly investment needed at your expected return.

What return should I assume?

Equity funds have historically returned around 10–12% long term in India, but actual returns vary. Use a realistic, slightly conservative figure.

Is the target guaranteed?

No. Market returns fluctuate, so review and adjust your SIP periodically. This is an estimate, not advice.

Understanding the Goal SIP Calculator

The Goal SIP Calculator works backwards from a target amount to tell you the monthly SIP (Systematic Investment Plan) you need to reach it. Instead of asking what your investment will grow to, it asks: given a goal corpus, time horizon and expected return, how much should you invest each month? It is built for Indian investors planning goals such as a child's education, a down payment, a car or retirement, and treats results as estimates for education, not investment advice.

How it works

Enter your target corpus (in rupees), the number of years until the goal, and an expected annual return. The tool converts the annual return to a monthly rate, computes the number of monthly instalments, and solves the future-value-of-annuity formula for the contribution. Because SIP instalments are usually made at the start of each month, it applies the annuity-due adjustment. Read the result as the monthly amount required at a constant assumed return. Real fund returns vary year to year, so treat the figure as a planning baseline and revisit it as markets and your goal change.

P = FV x r / ( ((1+r)^n - 1) x (1+r) ), where r = annual return / 12 and n = years x 12

Worked example

Suppose you want a corpus of Rs 50,00,000 in 15 years and assume a 12% annual return. The monthly rate r = 0.12/12 = 0.01 and n = 15 x 12 = 180 months. The annuity-due factor ((1.01^180 - 1)/0.01) x 1.01 is about 504.6. Dividing the goal by this factor gives P = 50,00,000 / 504.6, roughly Rs 9,910 per month. Investing about Rs 9,910 each month for 15 years at 12% is estimated to reach the Rs 50 lakh target.

Tips & common mistakes

  • Returns are assumptions, not guarantees - equity SIP returns vary widely year to year, so model a conservative rate (e.g. 10-12%) as well as an optimistic one.
  • Account for inflation: a goal that costs Rs 50 lakh today may cost far more in 15 years, so inflate the target before solving.
  • Step-up SIPs (raising the amount yearly) can lower the starting instalment - this tool assumes a fixed monthly amount.
  • Longer horizons dramatically cut the required monthly amount thanks to compounding, so start early where possible.
  • This is an educational estimate, not a recommendation to buy any specific fund; consult a SEBI-registered adviser for personal decisions.
