How to calculate

Computes the maturity value of a monthly SIP (systematic investment plan) in rupees at an expected yearly return, with an optional yearly step-up.

Example with the default inputs (Monthly investment (₹) 10,000, Expected return a year 12%, For how long? (years) 10, Step up each year by 0%): Investing ₹10,000 a month at 12% for 10 years grows to ₹2,323,391, of which ₹1,123,391 is returns.

Method: FV = P × ((1 + i)^n − 1) ÷ i × (1 + i), with P the monthly investment, i the yearly return ÷ 12, and n the number of months; worked month by month, with a step-up raising P each year.

  • The return stays the same every month. Mutual fund returns go up and down.
  • The monthly rate is the yearly return divided by 12, as most SIP calculators use.
  • Each instalment is invested at the start of its month.
  • Exit loads, expense ratios already in the return, and taxes are not included.
  • This is an estimate for planning, not financial advice.

How the maturity value is worked out

The calculator runs month by month. The monthly rate is the expected yearly return ÷ 12 (as a decimal): i = r ÷ 12. This is the convention most SIP calculators use.

Each month:

  1. The month’s instalment is invested at the start of the month.
  2. The return for the month is (value + instalment) × i, and it is added.

Step-up. The instalment in year k (k = 1, 2, 3, …) is P × (1 + step-up)^(k − 1). An empty step-up counts as 0%.

With no step-up, the maturity value after n months is:

FV = P × ((1 + i)^n − 1) ÷ i × (1 + i)

(or P × n when the return is 0).

The results:

  • Maturity value is the value after the last month.
  • Amount invested adds every instalment. Estimated returns is the maturity value minus the amount invested.

Amounts are in rupees and shown rounded to whole rupees.

Assumptions

  • The return is the same every month. Real fund returns vary.
  • Exit loads and taxes are not taken out.
  • This is an estimate for planning, not financial advice.

Worked examples by hand

₹1,000 a month at 8% for 25 years (AMFI’s example). i = 0.08 ÷ 12 = 0.0066667 and n = 300. (1 + i)^300 = 7.340176. FV = 1,000 × (7.340176 − 1) ÷ 0.0066667 × 1.0066667 = 1,000 × 951.0264 × 1.0066667 = ₹957,367, which is the ₹9.57 lakh AMFI gives. The amount invested is 300 × 1,000 = ₹300,000 (₹3 lakh).

₹5,000 a month at 12% for 10 years. i = 0.01 and n = 120. 1.01^120 = 3.300387. FV = 5,000 × (3.300387 − 1) ÷ 0.01 × 1.01 = 5,000 × 232.3391 = ₹1,161,695. The amount invested is ₹600,000, so the estimated returns are ₹561,695.

₹1,000 a month with a 10% step-up, at 0%, for 2 years. Year 1: 12 × ₹1,000 = ₹12,000. Year 2: 12 × ₹1,100 = ₹13,200. Maturity value ₹25,200, all of it invested.

The same step-up at 12%. One year of ₹1,000 instalments grows to 1,000 × (1.01^12 − 1) ÷ 0.01 × 1.01 = ₹12,809.33. That grows 12 more months (× 1.01^12 = 1.126825) to ₹14,433.88, and year 2’s instalments are 1.1 times year 1’s: ₹14,090.26. Maturity value ₹28,524, from ₹25,200 invested.

Other questions people ask

What is a SIP?

A SIP (systematic investment plan) is a way to invest a fixed amount in a mutual fund scheme at regular intervals, usually every month, instead of one lump sum. AMFI, the association of Indian mutual funds, describes it this way on its investor pages.

How is the SIP maturity value calculated?

With a monthly instalment P, a monthly rate i (the yearly return ÷ 12), and n months: maturity value = P × ((1 + i)^n − 1) ÷ i × (1 + i). The last (1 + i) is there because each instalment is invested at the start of its month and earns that month’s return.

What return should I expect from a SIP?

Nobody can promise one. Equity mutual fund returns rise and fall, and past returns do not guarantee future ones. The calculator uses one fixed rate for every month, so the answer is an estimate. Try a few rates to see a range.

What is a step-up SIP?

A step-up (or top-up) SIP raises the monthly amount each year, often in line with a pay rise. With a 10% step-up, ₹10,000 a month in year 1 becomes ₹11,000 a month in year 2 and ₹12,100 in year 3. Enter the step-up under "Step-up SIP".

Is the SIP return taxed?

Gains on mutual fund units are taxed as capital gains when you redeem them, at rates that depend on the type of fund and how long you held each instalment. The calculator shows returns before tax and before any exit load.

What is rupee cost averaging?

Because a SIP invests the same amount every month, it buys more units when the price (NAV) is low and fewer when it is high. AMFI’s example: ₹1,000 buys 50 units at a NAV of ₹20, but 100 units at a NAV of ₹10. This calculator uses a steady return, so it does not show that effect.
