How SIP Returns Are Calculated
SIP returns are calculated using the compound interest formula applied to each monthly installment:
SIP Maturity Value = P × [{(1 + r)^n − 1} ÷ r] × (1 + r)
Where:
- P = Monthly SIP amount (₹)
- r = Monthly return rate = Expected annual return ÷ 12 ÷ 100
- n = Total number of months (Years × 12)
Worked Example
Monthly SIP: ₹5,000 | Annual return: 12% | Duration: 15 years
- Total amount invested: ₹9,00,000
- Estimated maturity value: ₹25,22,880
- Wealth gained (returns): ₹16,22,880
That's a 2.8× gain on your investment — the power of compounding over 15 years.
SIP Returns Calculator Table — ₹5,000/Month at 12% p.a.
| Duration | Total Invested | Maturity Value | Wealth Gained |
|---|---|---|---|
| 5 Years | ₹3,00,000 | ₹4,12,432 | ₹1,12,432 |
| 10 Years | ₹6,00,000 | ₹11,61,695 | ₹5,61,695 |
| 15 Years | ₹9,00,000 | ₹25,22,880 | ₹16,22,880 |
| 20 Years | ₹12,00,000 | ₹49,95,740 | ₹37,95,740 |
| 25 Years | ₹15,00,000 | ₹94,88,247 | ₹79,88,247 |
Based on 12% p.a. expected return. Actual mutual fund returns vary. Past performance is not a guarantee of future returns.
What is Step-Up SIP?
A Step-Up SIP (also called a Top-Up SIP) automatically increases your monthly investment by a fixed percentage each year. For example, if you start a ₹5,000/month SIP with a 10% annual step-up, your investment becomes ₹5,500 in year 2, ₹6,050 in year 3, and so on.
Why Step-Up SIP matters: As your salary grows, increasing your SIP proportionally dramatically accelerates wealth creation. A 10% annual step-up on ₹5,000/month over 20 years can nearly double your maturity value compared to a flat SIP.
Frequently Asked Questions
What is a SIP calculator?
A SIP calculator estimates the future value of your mutual fund investments made through a Systematic Investment Plan. You enter your monthly investment amount, expected annual return, and duration — and the calculator shows your maturity amount, total invested, and estimated returns.
Is a 12% annual return on SIP realistic?
Historically, diversified equity mutual funds in India have delivered 12–15% annual returns over 10+ year periods, though this is not guaranteed. For conservative planning, using 10–11% is advisable. Debt funds typically return 6–8%. Always use a return rate that matches your chosen fund category.
What is the minimum SIP amount I can start with?
Most mutual funds in India allow SIPs starting at ₹500 per month. Some funds have a minimum of ₹100/month. There is no upper limit on SIP investment amounts.
Should I choose SIP or lump sum investment?
SIP is generally preferred over lump sum because it uses Rupee Cost Averaging — you buy more units when prices are low and fewer when prices are high, reducing your average cost over time. Lump sum works better when markets are at a cyclical low.
Is SIP tax-free?
Returns on SIP investments are taxed based on the fund type and holding period. For equity mutual funds: gains held over 1 year are Long Term Capital Gains (LTCG) taxed at 12.5% above ₹1.25 lakh per year (from FY 2024–25). Short-term gains (under 1 year) are taxed at 20%. ELSS funds offer ₹1.5 lakh tax deduction under Section 80C.
Can I stop or pause my SIP anytime?
Yes. Most mutual funds allow you to pause, reduce, increase, or stop your SIP at any time without penalties. Check your specific fund's terms for minimum notice periods.
