Calculating your maturity value is straightforward once you know the SIP formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the SIP Calculator.
What is SIP?
Estimate the maturity value of your monthly SIP mutual-fund investments. The figure you are solving for here is the maturity value, expressed in INR.
The SIP formula
This calculation combines several inputs through a multi-step method rather than a single one-line formula. Enter the values below and the calculator resolves each step in order. The inputs it needs are:
- Monthly investment — a money amount. Example: ₹5,000.
- Expected return (p.a.) — a percentage, such as an annual rate. Example: 12%.
- Time period — a value you set on the slider. Example: 10 years.
How to calculate it step by step
- Write down the monthly investment (for example, ₹5,000).
- Write down the expected return (p.a.) (for example, 12%).
- Note the time period (for example, 10 years).
- Apply the formula above to get your maturity value.
- Double-check the result with the SIP Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Monthly investment | ₹5,000 |
| Expected return (p.a.) | 12% |
| Time period | 10 years |
| Maturity value | ₹11,61,695 |
| Total invested | ₹6,00,000 |
| Estimated returns | ₹5,61,695 |
With monthly investment of ₹5,000, expected return (p.a.) of 12% and time period of 10 years, the maturity value works out to ₹11,61,695.
Example 2
With monthly investment of ₹10,000, expected return (p.a.) of 12% and time period of 10 years, the maturity value works out to ₹23,23,391.
| Result | Value |
|---|---|
| Maturity value | ₹23,23,391 |
| Total invested | ₹12,00,000 |
| Estimated returns | ₹11,23,391 |
Example 3
With monthly investment of ₹2,500, expected return (p.a.) of 12% and time period of 10 years, the maturity value works out to ₹5,80,848.
| Result | Value |
|---|---|
| Maturity value | ₹5,80,848 |
| Total invested | ₹3,00,000 |
| Estimated returns | ₹2,80,848 |
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
- Annual rates must be converted to the period you are calculating for (for example, divide an annual rate by 12 for a monthly figure).
