Introduction
SIP (Systematic Investment Plan) is a disciplined approach to investing fixed amounts monthly in mutual funds. Rupee cost averaging reduces market timing risk, making SIP ideal for salaried investors building long-term wealth in India.
Numverto SIP Calculator projects future value based on expected annual returns, showing year-by-year growth. Pair with our SIP guide and Compound Interest Calculator.
SIP Formula
M = P × ((1 + i)n – 1) / i × (1 + i), where P = monthly investment, i = monthly rate (annual rate ÷ 12 ÷ 100), n = total months.
Step-by-Step Examples
₹10,000/month at 12% for 10 years
Total invested: ₹12,00,000. Estimated maturity: ₹23,23,391. Returns: ₹11,23,391.
₹5,000/month at 15% for 20 years
Total invested: ₹12,00,000. Estimated maturity: ₹75,79,775. Power of compounding over long tenure.

What is a SIP Calculator?
A SIP (Systematic Investment Plan) calculator helps you estimate the future value of your regular monthly investments in mutual funds. By entering your monthly investment, expected annual return, and investment duration, you can see how compounding grows your wealth over time. This tool is essential for financial planning, whether you're saving for retirement, a house, education, or any long-term goal.
How to Use This SIP Calculator
- Enter your monthly SIP amount: the fixed amount you'll invest every month (e.g. ₹10,000).
- Enter expected annual return rate: for equity mutual funds, 12% is a common long-term assumption. For debt funds, use 7-8%.
- Enter investment period: in years (longer = dramatically higher returns due to compounding).
- View results: total invested, estimated returns, and maturity value appear instantly.
- Check year-by-year table: notice how returns accelerate in later years. This is the power of compounding.
SIP vs Lump Sum Investment
| Feature | SIP | Lump Sum |
|---|---|---|
| Investment style | Fixed amount every month | One-time large investment |
| Market timing risk | Low (rupee cost averaging) | High (entire amount at one price) |
| Best for | Salaried people, regular income | Windfall gains, bonus, inheritance |
| Discipline | Automatic, builds habit | Requires timing decision |
| In falling market | Buys more units at lower prices (beneficial) | Entire investment loses value immediately |
| In rising market | Returns slightly lower (averaging up) | Higher returns (all invested at low point) |
| Minimum amount | ₹500/month | ₹5,000-10,000 typically |
Verdict: For most salaried investors, SIP is the safer and more practical choice. It removes emotion from investing and benefits from market volatility through averaging.
Power of Compounding in SIP
Compounding means earning returns on your returns. In a SIP, each month's investment earns returns, and those returns earn further returns in subsequent months. The longer you stay invested, the more dramatic this effect becomes.
| Years | Invested (₹10K/month) | Value at 12% | Returns | Returns as % of Invested |
|---|---|---|---|---|
| 5 | ₹6,00,000 | ₹8,24,859 | ₹2,24,859 | 37% |
| 10 | ₹12,00,000 | ₹23,23,391 | ₹11,23,391 | 94% |
| 15 | ₹18,00,000 | ₹50,45,760 | ₹32,45,760 | 180% |
| 20 | ₹24,00,000 | ₹99,91,479 | ₹75,91,479 | 316% |
| 25 | ₹30,00,000 | ₹1,89,76,351 | ₹1,59,76,351 | 532% |
| 30 | ₹36,00,000 | ₹3,52,99,138 | ₹3,16,99,138 | 881% |
Key insight: In the first 10 years, returns roughly equal your investment. But from year 20 onwards, returns are 3-9x your total invested amount. This is why starting early is the single most important financial decision.
Rule of 72: Divide 72 by your annual return rate to estimate how many years it takes to double your money. At 12% return, your money doubles roughly every 6 years.
Best SIP Amount Based on Income
Financial advisors recommend investing 20-30% of your take-home salary via SIP. Here's a practical guide:
| Monthly Income | Suggested SIP | In 20 years at 12% |
|---|---|---|
| ₹25,000 | ₹5,000 (20%) | ₹49.9 lakh |
| ₹50,000 | ₹12,500 (25%) | ₹1.25 crore |
| ₹75,000 | ₹20,000 (27%) | ₹2.0 crore |
| ₹1,00,000 | ₹30,000 (30%) | ₹3.0 crore |
| ₹1,50,000 | ₹45,000 (30%) | ₹4.5 crore |
Start with whatever you can afford, even ₹1,000/month builds the habit. Increase by 10% annually as income grows (Step-up SIP).
SIP Investment Mistakes to Avoid
- Stopping SIP during market crashes: This is the worst time to stop. Market dips let you buy more units at lower prices, exactly when SIP delivers its best advantage (rupee cost averaging).
- Investing too little for too short: ₹500/month for 2 years won't build meaningful wealth. Aim for at least 5-7 years minimum to see compounding work.
- Chasing past returns: A fund that gave 30% last year won't necessarily repeat. Choose funds based on 5-10 year consistent performance, not 1-year toppers.
- Not increasing SIP with income: If your salary grows 10% annually but SIP stays flat, you're effectively reducing your investment rate each year. Use Step-up SIP.
- Redeeming for short-term needs: SIP is for long-term goals. Keep 3-6 months emergency fund separately so you never need to break your SIP investments.
Types of SIP
Regular SIP
Fixed amount invested on a fixed date every month. Most common and simplest type. Best for beginners who want disciplined, automated investing.
Step-up SIP (Top-up SIP)
Automatically increases your SIP amount by a set percentage (usually 10-25%) every year. Aligns with salary growth and significantly boosts the final corpus. A ₹10,000 SIP with 10% annual step-up for 20 years at 12% grows to ₹1.74 crore vs ₹99.9 lakh with regular SIP.
Flexible SIP
Allows you to increase or decrease the monthly amount based on cash flow. Useful for freelancers or business owners with irregular income. You set a base amount and can adjust up to 25x or down to zero temporarily.
Perpetual SIP
No end date. Continues until you actively stop it. Ideal for long-term wealth building where you don't have a fixed goal date. Most online SIP setups default to perpetual mode.
SIP Formula Explained
M = P × ((1+i)n - 1) / i × (1+i)
Where:
- M = Maturity value (total future value)
- P = Monthly SIP investment amount
- i = Monthly rate of return (annual rate ÷ 12 ÷ 100)
- n = Total number of monthly installments (years × 12)
This formula accounts for each month's investment compounding independently for its remaining duration, making SIP a powerful wealth-building tool over time.
