SIP Calculator – Calculate Mutual Fund SIP Returns Online
Estimate how much your monthly mutual fund SIP could grow to, with invested amount and estimated returns.
SIP Calculator
What is a SIP calculator?
A Systematic Investment Plan (SIP) lets you invest a fixed amount in a mutual fund every month. Our SIP calculator estimates how much that monthly habit could grow to, based on the amount you invest, the expected annual return and the number of years you stay invested. It shows the total value, the amount you actually put in and the estimated gains, along with a chart so you can see how much of the final corpus comes from compounding.
The calculator is useful when you are planning for goals such as a child’s education, a house down payment or retirement. Change the sliders and the results update instantly, so you can test different amounts, return assumptions and time periods in seconds.
SIP formula used
SIP instalments are usually invested at the beginning of every month, so the maturity value is the future value of an annuity due:
FV = P × [((1 + i)^n − 1) / i] × (1 + i)
- P – monthly SIP amount
- i – monthly rate of return (annual return ÷ 12 ÷ 100)
- n – number of monthly instalments (years × 12)
For example, ₹10,000 a month for 10 years at 12% gives i = 0.01 and n = 120, so FV = 10,000 × [(1.01^120 − 1) / 0.01] × 1.01 = ₹23,23,391. You invest ₹12,00,000, and about ₹11,23,391 is estimated gain.
How to use the SIP calculator
- Enter your monthly investment amount using the slider or the input box.
- Set the expected annual return. Equity funds have historically delivered 10–14% over long periods, debt funds 6–8%; these are not guaranteed.
- Choose how many years you plan to stay invested.
- Read the total value, invested amount and estimated returns in the result cards and chart.
Example: ₹10,000 monthly SIP at 12%
The table below shows how the same ₹10,000 monthly SIP grows over different time periods at an assumed 12% annual return. Notice how gains overtake the invested amount as the years pass – that is the power of compounding.
| Period | Amount invested | Estimated value | Estimated gains |
|---|---|---|---|
| 5 years | ₹6,00,000 | ₹8,24,864 | ₹2,24,864 |
| 10 years | ₹12,00,000 | ₹23,23,391 | ₹11,23,391 |
| 15 years | ₹18,00,000 | ₹50,45,760 | ₹32,45,760 |
| 20 years | ₹24,00,000 | ₹99,91,479 | ₹75,91,479 |
| 25 years | ₹30,00,000 | ₹1,89,76,351 | ₹1,59,76,351 |
Why time matters more than amount
Doubling the time period from 10 to 20 years makes the corpus more than four times larger, even though the invested amount only doubles. Starting early is the single most powerful lever an investor controls. A step-up SIP, where you raise the instalment every year in line with your salary, accelerates this further.
Benefits of investing through SIP
- Rupee cost averaging: you buy more units when markets fall and fewer when they rise, smoothing your average cost.
- Discipline: an automatic monthly debit builds a savings habit without needing to time the market.
- Low entry amount: many funds accept SIPs from ₹100 to ₹500 a month.
- Flexibility: you can pause, increase or stop most SIPs at any time.
Taxes on SIP returns
For equity funds, long-term capital gains above ₹1.25 lakh a year are taxed at 12.5% when units are held for more than 12 months, and short-term gains are taxed at 20%. Each SIP instalment is treated as a separate purchase for holding-period purposes. The calculator shows pre-tax values, so keep taxes in mind when planning goals.
If you are balancing investments with a loan, compare your expected SIP returns with your loan interest rate using our home loan EMI calculator and prepayment calculator before deciding where extra money should go.
SIP vs lump sum
A lump-sum investment puts all your money to work on day one, so it can grow larger if markets rise steadily. A SIP spreads purchases over time and reduces the risk of investing everything at a market peak. For most salaried investors who earn monthly, SIP is the natural fit because it matches cash flow. If you receive a bonus, you can invest part of it as a lump sum and continue your regular SIP alongside it.
Frequently asked questions
Is the SIP calculator result guaranteed?
No. Mutual fund returns depend on market performance. The calculator assumes a constant annual return, while real returns vary every year. Use it as a planning estimate, not a promise.
Why does the calculator assume investment at the start of the month?
Most SIP mandates debit money at the beginning of the investment cycle, so each instalment earns returns for the full month. This annuity-due method is the standard used by Indian AMCs and fund platforms.
What return should I assume for an equity SIP?
Many planners use 10–12% for diversified equity funds over 10+ years and 6–8% for debt funds. Use a conservative figure for important goals.
Can I change my SIP amount later?
Yes. You can start a new SIP, use a step-up (top-up) facility, or stop and restart. Recalculate with the new amount to update your goal plan.
