A SIP calculator estimates how much your monthly mutual fund investment will grow into over time. Enter your monthly investment amount, expected annual return rate, and investment duration above to instantly see your total invested amount, estimated returns, and final maturity value — free, with no signup required.
What Is a SIP (Systematic Investment Plan)?
A Systematic Investment Plan (SIP) is a method of investing a fixed amount of money at regular intervals — usually monthly — into a mutual fund or investment scheme, instead of investing a large sum at once. SIPs use rupee-cost averaging to smooth out the impact of market volatility, since you automatically buy more units when prices are low and fewer units when prices are high.
Because contributions are automated and predictable, SIP is one of the most common ways for individual investors to build long-term wealth without needing to time the market.
SIP Calculator Formula: How Returns Are Calculated
This calculator uses the standard future value of annuity due formula, since SIP installments are typically invested at the start of each period:
| Variable | Meaning |
|---|---|
| FV | Future value / maturity amount of the SIP |
| P | Amount invested each month |
| i | Expected monthly rate of return (annual rate ÷ 12) |
| n | Total number of monthly installments (years × 12) |
SIP Return Example: 5,000/Month at 12% Expected Return
Here's what a monthly SIP of 5,000 at a 12% expected annual return looks like over different durations:
| Duration | Total Invested | Est. Maturity Value | Est. Gains |
|---|---|---|---|
| 10 years | 600,000 | ~1,161,700 | ~561,700 |
| 15 years | 900,000 | ~2,523,000 | ~1,623,000 |
| 20 years | 1,200,000 | ~4,995,700 | ~3,795,700 |

Step-Up SIP: Increasing Your SIP Amount Every Year
A step-up SIP (or top-up SIP) increases your monthly investment by a fixed percentage each year — for example, raising a 5,000/month SIP by 10% annually as your income grows. Because later contributions are larger and still benefit from long-term compounding, a step-up SIP typically builds a significantly larger corpus than a flat SIP of the same starting amount over the same period.
| SIP Type | Monthly Amount | Behavior |
|---|---|---|
| Flat SIP | Fixed | Same investment amount every month for the full duration |
| Step-Up SIP | Increases yearly | Investment amount rises by a set % each year, boosting the final corpus |
SIP vs. Lump Sum Investment
| Factor | SIP | Lump Sum |
|---|---|---|
| Market timing risk | Lower (averaged over time) | Higher (single entry point) |
| Capital required upfront | Low | High |
| Best suited for | Salaried / regular income investors | Investors with a large one-time amount |
| Discipline required | Built-in via automation | Self-managed |
Benefits of SIP Investing
- Rupee-cost averaging — reduces the impact of short-term market volatility.
- Power of compounding — returns are reinvested, accelerating growth over long durations.
- Investment discipline — automated monthly deductions build a consistent saving habit.
- Flexibility — start with small amounts, increase contributions over time, and pause or stop when needed.
- Goal-based planning — model specific targets like retirement, education, or a home down payment.
Factors That Affect Your SIP Returns
- Expected annual rate of return assumed
- Duration of the investment (longer periods compound more)
- Consistency of monthly contributions
- Whether you use a flat SIP or a step-up SIP
- Fund expense ratio and exit load, if applicable
- Market conditions and asset class (equity vs. debt vs. hybrid)
