How this calculator works
A systematic investment plan is simply a standing instruction to invest a fixed amount at a fixed interval, usually monthly. Every instalment buys units at whatever the price is that day, so you accumulate more units when markets fall and fewer when they rise. That is rupee-cost averaging, and it removes the need to decide when to invest.
The maths treats each instalment as a separate investment compounding for however many months remain. An instalment paid in month one compounds for the entire period; one paid in the final month compounds for a single month. Adding them all up gives the closed-form SIP formula used here.
This is why the last few years of a long SIP produce such large numbers. The corpus is at its biggest, so the same percentage return generates far more rupees. In a twenty-year SIP, the final five years typically add more value than the first fifteen.
The step-up option matters more than most people expect. Raising the instalment by 10% each year, roughly in line with a salary increase, can produce a substantially larger corpus than a flat SIP, because the increases arrive early enough to compound.
The formula
Future value of a SIP
FV = P × ((1 + i)ⁿ − 1) ÷ i × (1 + i)
- P
- Monthly instalment
- i
- Monthly return = annual return ÷ 12 ÷ 100
- n
- Total number of instalments
The final × (1 + i) reflects instalments being invested at the start of each month. This is the convention every mainstream Indian SIP calculator uses.
With an annual step-up
No closed form — the instalment changes every twelve months, so the calculation runs month by month.
Worked example: ₹10,000 a month at 12% for 15 years
Deepa starts a ₹10,000 monthly SIP and assumes a 12% annual return over 15 years.
| Monthly instalment | ₹10,000 |
|---|---|
| Monthly return (12 ÷ 12 ÷ 100) | 0.01 |
| Number of instalments | 180 |
| Total invested | ₹18,00,000 |
| Estimated final value | ₹50,45,760 |
| Estimated returns | ₹32,45,760 |
| Returns as a share of the amount invested | 180% |
Nearly two-thirds of the final value is return rather than contribution. Adding a 10% annual step-up would raise total investment to about ₹38 lakh and the estimated value to roughly ₹92 lakh — the increases matter because they arrive early enough to compound.
Things worth knowing
- Market-linked returns are not guaranteed. The rate you enter is an assumption, not a prediction, and actual returns will be higher in some years and negative in others.
- The expected return you enter is the single biggest driver of the result. Changing it from 12% to 10% reduces a fifteen-year corpus by roughly a fifth. Treat any projection as a range, not a figure.
- Returns shown here are before tax. Equity mutual funds held beyond the long-term threshold are taxed at a concessional rate above an annual exemption; debt funds are taxed differently again. Check the current rules for the specific fund type.
- Expense ratios reduce your actual return. The figure a fund reports is usually already net of expenses, but a high-cost fund can quietly cost several percent of the final corpus over a long period.
- Missing instalments is the most common reason real SIPs underperform projections. Set the debit date shortly after your salary credit date.
- A SIP is a way of investing, not an asset class. The return depends entirely on what you invest in — an equity fund, a debt fund and a gold fund will behave very differently.
