About this calculator
The return you enter is an assumption. Equity funds do not grow at a fixed rate: some years are well above average and some are negative. Use the result to compare scenarios, for example 10% against 12%, or 10 years against 15, rather than as a forecast.
How to use it
- Enter the amount you plan to invest every month.
- Enter a yearly return you consider realistic for the fund type.
- Enter how many years you will keep investing.
- Compare the total invested with the estimated value, and look at the yearly chart to see how growth speeds up in later years.
The formula
- FV
- the estimated value at the end
- P
- the amount invested each month
- i
- the monthly rate: expected yearly return ÷ 12 ÷ 100
- n
- the number of monthly instalments
The final × (1 + i) assumes each instalment is invested at the start of the month, which is the convention most Indian SIP calculators use.
Worked example
₹5,000 a month for 15 years at 12%
- P = ₹5,000, i = 12 ÷ 12 ÷ 100 = 0.01, n = 15 × 12 = 180.
- (1 + i)180 = 1.01180 = 5.99580.
- FV = 5,000 × [(5.99580 − 1) ÷ 0.01] × 1.01 = ₹25,22,880.
- You would have put in ₹9,00,000, so the estimated returns are ₹16,22,880.
What the result means
The gap between the invested amount and the final value is compounding at work: returns earn further returns. In the chart, the returns bar is small in the first few years and becomes the larger part later on. Staying invested longer matters more than any single year’s return.
The result is before tax. Gains on equity mutual funds are taxed as capital gains when you redeem, and the rates and exemptions depend on the holding period and the tax rules in force at that time.
Assumptions
- The same amount is invested every month, at the start of the month.
- The yearly return is constant and compounds monthly.
- No units are redeemed before the end of the period.
- Expense ratio is taken to be already reflected in the return you enter.
Limitations
- Market-linked returns are not fixed. The actual value on your chosen date could be much higher or lower than this estimate.
- Real SIPs buy units at a different price each month. The actual return is measured with XIRR, which this calculator does not compute.
- Exit loads, stamp duty on purchases and taxes are not included.
- Inflation is not deducted, so the result is in future rupees, not today’s value.
Frequently asked questions
What return should I assume?
There is no right number. Many people run the calculator at two or three rates, for example 8%, 10% and 12% for an equity fund, and plan around the lower result.
Is the SIP amount guaranteed to grow?
No. Mutual fund investments are subject to market risk. The result is an estimate based on the return you enter.
Why is my result slightly different from another SIP calculator?
Calculators differ in whether each instalment is invested at the start or end of the month, and in how they turn a yearly rate into a monthly one. This one assumes start-of-month investing and divides the yearly rate by 12.
Does increasing the SIP every year make a big difference?
Usually yes, because later, larger instalments still have years to compound. A step-up SIP calculator that models a yearly increase is planned for this site.
