What is a SIP Calculator?
A SIP Calculator is a free online tool that estimates the returns from your monthly mutual fund investments through a Systematic Investment Plan (SIP). It uses the principle of compound interest to project the future value of your investments based on the monthly contribution, expected return rate, and investment duration.
Our tool doubles as a step up SIP calculator (with annual contribution increase), a lump sum SIP calculator for one-time investments, and a SIP calculator with inflation so you can see your real, inflation-adjusted corpus. You can also model a daily SIP, a gold SIP or a combined SIP and SWP strategy from the same page.
SIPs are India's most popular wealth-building tool. According to AMFI data, monthly SIP contributions in India crossed ₹26,000 crore in 2025 — a clear indication of how millions of Indians are systematically investing for their financial goals.
SIP EMI Calculator & Indian Bank SIP Calculator
People often search for a "SIP EMI calculator" because a SIP feels like a monthly EMI you pay to yourself — a fixed investment amount debited every month for a chosen investment tenure. The difference is that an EMI clears a debt, while a SIP builds wealth. This page acts as that SIP EMI calculator: enter your monthly investment amount, the expected rate of interest, and the number of years, and it shows the corpus you will build.
If you invest through a bank-linked mutual fund platform, this tool also works as an Indian Bank SIP calculator, an SBI or HDFC SIP calculator — the SIP calculator formula is identical regardless of which bank or fund house processes your SIP investments. What matters for your final corpus is only three inputs: the monthly amount, the rate of return, and how long you stay invested.
SIP Calculator vs Fixed Deposit
Many first-time investors compare a SIP calculator with a fixed deposit calculator before deciding where to put their money. A fixed deposit gives a guaranteed rate of interest (around 7% in 2025) with zero risk, while an equity SIP targets a higher 12–15% return but carries market risk over shorter periods. Over a long investment tenure of 10 years or more, SIP investments have historically outpaced fixed deposits — provided you stay invested through market ups and downs rather than redeeming early.
| Factor | SIP (Equity) | Fixed Deposit |
|---|---|---|
| Expected return | 12–15% (market-linked) | ~7% (fixed) |
| Risk | Medium–High (short term) | Very low |
| Best investment tenure | 5+ years | Any |
| Liquidity | High (except ELSS) | Locked till maturity |
SIP Formula — How is SIP Return Calculated?
The mathematical formula used to calculate SIP returns is:
Where:
- M = Maturity amount
- P = Monthly SIP amount
- r = Periodic monthly rate of return ((1 + annual return)^(1/12) – 1)
- n = Total number of months
Important Note on Monthly Returns
A common mistake is dividing the annual return by 12. For a 12% annual return, the correct monthly rate is 0.95% (not 1%) because returns compound. Our calculator uses this accurate formula automatically.
The Power of Compounding — Why Start Early?
Albert Einstein famously called compound interest "the eighth wonder of the world." Here's how starting early dramatically changes your wealth:
- Start at 25: ₹10,000 SIP for 35 years at 12% = ₹5.5 Crore
- Start at 30: ₹10,000 SIP for 30 years at 12% = ₹3.5 Crore
- Start at 35: ₹10,000 SIP for 25 years at 12% = ₹1.9 Crore
- Start at 40: ₹10,000 SIP for 20 years at 12% = ₹1 Crore
Every 5-year delay nearly halves your final corpus!
What is Step-Up SIP?
A Step-Up SIP (also called Top-Up SIP) lets you increase your monthly SIP amount annually by a fixed percentage. This aligns your investments with your salary growth and dramatically boosts the final corpus.
Step-Up SIP Example
Compare ₹10,000 SIP for 20 years at 12% return:
- Regular SIP: Final corpus = ₹99.9 Lakhs
- 10% Step-Up SIP: Final corpus = ₹2.4 Crore (240% more!)
Benefits of Investing Through SIP
- Rupee Cost Averaging: Buy more units when markets fall, fewer when they rise
- Disciplined Investing: Auto-debit instills financial discipline
- Low Entry Barrier: Start with just ₹500/month
- Power of Compounding: Returns earn returns over time
- Goal-Based: Plan for retirement, child's education, home down payment
- No Market Timing Required: Removes emotion from investing
SIP vs Lumpsum — Which is Better?
SIP wins for: Salaried individuals, market timing uncertainty, building discipline, beginners
Lumpsum wins for: When markets are clearly undervalued, large windfall amounts, experienced investors

Best SIP Amounts by Income
- ₹25,000 salary: ₹2,500 - ₹5,000 SIP (10-20%)
- ₹50,000 salary: ₹7,500 - ₹15,000 SIP (15-30%)
- ₹1,00,000 salary: ₹20,000 - ₹35,000 SIP (20-35%)
- ₹2,00,000+ salary: ₹50,000+ SIP (25-40%)
How to Choose the Right Mutual Fund for SIP
- Define Your Goal: Retirement, education, home — different goals need different funds
- Time Horizon: <3 years → debt, 3-7 years → hybrid, 7+ years → equity
- Risk Appetite: Match fund risk with your tolerance
- Past Performance: Look at 5, 7, 10-year returns (not 1-year)
- Expense Ratio: Lower is better (Direct plans < Regular plans)
- Fund Manager Track Record: Consistent managers add value
Tax Implications on SIP Returns
- Equity Funds (>65% in equity): LTCG 12.5% above ₹1.25L (after 1 yr); STCG 20%
- Debt Funds: Taxed at your income tax slab rate
- ELSS (Tax-saver) Funds: ₹1.5L deduction under 80C, 3-year lock-in
- Hybrid Funds: Taxed based on equity vs debt allocation
SIP EMI Calculator: Balance Investing and Loan Repayment
The SIP EMI calculator approach helps salaried Indians who are simultaneously investing in mutual funds and paying an EMI on a home, car or personal loan. The investment decision at any point in time comes down to: should the next spare rupee go to an extra EMI prepayment (guaranteed interest saving equal to the loan rate) or to an equity SIP (market-linked, higher expected return but not guaranteed)?
The rule of thumb: if your loan interest rate is higher than the expected SIP return, prepay first. If lower, SIP wins. A home loan at 8.5% vs an equity SIP at 12% strongly favours the SIP; a credit-card balance at 36% is the opposite. Use both an EMI calculator and a SIP return calculator side-by-side to make the investment decision correctly.

SIP Return Calculator: What Your Corpus Will Actually Be Worth
A SIP return calculator shows the nominal corpus your monthly investments will grow to at a given rate of return. But the corpus in year 20 is not what it seems — after inflation and long-term capital gains tax, a ₹1 crore projection is worth roughly ₹40–50 lakh in today's purchasing power. That gap is the biggest investment decision most SIP investors ignore.
The core SIP return formula: FV = P × [((1 + r)^n − 1) / r] × (1 + r), where P is the monthly SIP, r the monthly return, n the number of months. See our dedicated SIP Return Calculator guide for realistic return assumptions by mutual fund category and how to model post-tax numbers.
The single biggest lever in any SIP projection is the expected rate of return you assume. A change from a 10% to a 12% expected rate of return on a ₹10,000 monthly SIP over 20 years adds roughly ₹25 lakh to the final corpus. Because equity returns are not guaranteed, always run the calculator across a range of expected rate of return values — a conservative 8%, a realistic 12%, and an optimistic 14% — and plan against the lower end.
Avoid the 3 common monthly SIP calculator mistakes that quietly shrink your corpus.Indian Bank SIP Calculator: RD and Mutual Fund Options
An Indian Bank SIP calculator is used by two audiences: those running a Recurring Deposit through the bank, and those buying mutual funds via IndOASIS or a distributor. The RD version uses simple compound-interest math at the bank's declared RD rate (currently 6.75–7.25%). The mutual fund version uses the same equity SIP formula as any other platform, with the return depending on the fund, not the bank.
Our Indian Bank SIP Calculator guide shows both approaches side by side, with an RD-vs-mutual-fund investment decision framework.
SIP Calculator Fixed Deposit Comparison
The SIP calculator fixed deposit comparison is the single most useful decision tool for new Indian investors. FDs give a guaranteed 6–7% pre-tax; equity SIPs give 10–14% historical average, taxable at 12.5% LTCG above ₹1.25 lakh per year. Post-tax, over 10+ year horizons, equity SIPs win comfortably — but only if you can stomach the volatility along the way.
Our SIP Calculator Fixed Deposit tool runs both side-by-side over 5, 10, 15 and 20-year horizons and shows the post-tax gap explicitly.
