SIP Calculator India 2026 - Mutual Fund SIP Returns, Formula & Investment Guide
TL;DR
SIP (Systematic Investment Plan) is the most disciplined way to invest in mutual funds in India. By investing a fixed amount every month, you benefit from rupee cost averaging and the power of compounding. A monthly SIP of Rs 10,000 at 12% CAGR grows to Rs 23.23 lakh in 10 years and Rs 99.91 lakh in 20 years - with just Rs 24 lakh invested. Start early, stay consistent, and let compounding do the heavy lifting. Key Facts:
- Minimum SIP amount: Rs 500/month (most mutual funds)
- No lock-in period for regular mutual fund SIPs (except ELSS - 3 years)
- SIP works through rupee cost averaging - buys more units when markets are low
- Step-up SIP (increasing SIP by 10% annually) can nearly double your corpus
- LTCG tax on equity MF: 12.5% on gains above Rs 1.25 lakh/year
SIP Returns Formula
The future value of SIP is calculated using the annuity formula:
FV = M x [{(1 + r)^n - 1} / r] x (1 + r)
Where:
- FV = Future value (maturity amount)
- M = Monthly SIP amount
- r = Monthly rate of return (annual rate / 12)
- n = Total number of SIP installments (months)
Example: Rs 10,000 SIP at 12% for 10 Years
r = 12% / 12 = 1% = 0.01
n = 10 x 12 = 120 monthsFV = 10,000 x [{(1.01)^120 - 1} / 0.01] x (1.01)
= 10,000 x [{3.30 - 1} / 0.01] x 1.01
= 10,000 x 230.03 x 1.01
= Rs 23,23,391
Total invested: Rs 12,00,000. Wealth gained: Rs 11,23,391 (93.6% return on investment).

Rupee Cost Averaging Explained
SIP's biggest advantage is rupee cost averaging. When markets fall, your fixed SIP amount buys more units. When markets rise, it buys fewer. Over time, this averages out your cost per unit.
| Month | NAV | Units Bought (Rs 10,000 SIP) |
|---|---|---|
| January | Rs 100 | 100.00 |
| February | Rs 80 (market dip) | 125.00 |
| March | Rs 90 | 111.11 |
| April | Rs 110 (recovery) | 90.91 |
| May | Rs 105 | 95.24 |
| Total | Avg NAV: Rs 97 | 522.26 units |

Frequently Asked Questions
Q: What is the ideal SIP amount to start with?
Start with what you can comfortably invest without straining your monthly budget. Even Rs 500/month is a valid starting point. A common rule is to invest 20-30% of your take-home salary. As your income grows, increase the SIP using the step-up feature. Consistency matters more than the amount.
Q: Can I stop or pause my SIP anytime?
Yes, SIPs can be paused or stopped anytime without penalty (except ELSS during the 3-year lock-in). Your existing units remain invested and continue to grow. You can restart the SIP later. However, frequent stopping defeats the purpose of disciplined investing.
Q: Is SIP better than lumpsum investment?
SIP is better for regular income earners who invest monthly. Lumpsum can outperform SIP if invested during a market low, but timing the market is nearly impossible consistently. For amounts above Rs 5 lakh, consider splitting between a lumpsum in a debt fund and an STP (Systematic Transfer Plan) into equity over 6-12 months.
Q: How are SIP returns taxed in India?
For equity mutual funds: STCG (units held less than 1 year) is taxed at 20%. LTCG (units held more than 1 year) above Rs 1,25,000 per year is taxed at 12.5%. Each SIP installment is treated as a separate investment, so the holding period is calculated individually for each installment.
