SIP Calculator
A SIP (Systematic Investment Plan) calculator helps you estimate the future value of your mutual fund investments when you invest a fixed amount at regular intervals. Instead of investing a lump sum all at once, a SIP lets you spread your investment across months or years, which reduces the impact of market volatility through rupee cost averaging. This calculator takes three inputs: your monthly investment amount, the expected annual return rate, and the investment tenure in years. It then computes the total amount you will have invested, the estimated returns earned through compounding, and the final maturity value. SIPs are one of the most popular ways to invest in mutual funds in India because they enforce discipline, require only a small amount each month, and benefit from the power of compound interest over long periods. The return rate you enter should be a realistic expectation based on the type of fund you are investing in - equity funds historically average 10-15% annually, while debt funds typically return 6-8%.
Formula
FV = P × [((1 + r)^n − 1) / r] × (1 + r) Where: FV = Future Value (maturity amount) P = Monthly investment amount r = Monthly interest rate (annual rate ÷ 12 ÷ 100) n = Total number of months (years × 12)
Example
Example: Invest Rs 5,000/month at 12% annual return for 10 years. Step 1: Monthly rate (r) r = 12 / 12 / 100 = 0.01 Step 2: Total months (n) n = 10 x 12 = 120 Step 3: Total invested = 5,000 x 120 = Rs 6,00,000 Step 4: Maturity value (FV) = 5,000 x [((1.01)^120 - 1) / 0.01] x 1.01 = Rs 11,61,695 (approx) Step 5: Estimated returns = 11,61,695 - 6,00,000 = Rs 5,61,695 Result: Your Rs 6 lakh investment grows to about Rs 11.6 lakh in 10 years, earning Rs 5.6 lakh in returns through the power of compounding.

Frequently Asked Questions
What is a SIP?
A Systematic Investment Plan (SIP) is a method of investing a fixed amount in mutual funds at regular intervals, typically monthly. It helps you build wealth gradually without needing a large lump sum, and it reduces the risk of timing the market by spreading investments over time.
How is SIP return calculated?
SIP returns use the future value of an annuity formula: FV = P x [((1+r)^n - 1) / r] x (1+r), where P is the monthly investment, r is the monthly interest rate (annual rate divided by 12 and by 100), and n is the total number of months. This formula accounts for the fact that each installment compounds for a different length of time.
What is a good annual return rate to use?
For equity mutual funds, a realistic expectation is 10-15% annually based on historical long-term averages. For debt funds, use 6-8%. Conservative investors may use 8-10% to be safe. Remember that mutual fund returns are not guaranteed and depend on market performance.
What happens if I increase my monthly SIP amount?
Increasing your monthly SIP amount has a direct and powerful effect on your maturity value. For example, doubling your investment from Rs 5,000 to Rs 10,000 per month will roughly double your maturity value, since the formula is linear with respect to the monthly amount (P).
Can I change my SIP amount midway?
Yes, most mutual fund houses allow you to increase, decrease, or pause your SIP amount. Some offer step-up SIPs that automatically increase your contribution by a fixed percentage each year, which can significantly boost your final corpus.
Are SIP returns guaranteed?
No, SIP returns are not guaranteed because they depend on the performance of the underlying mutual fund. The calculator shows an estimate based on the return rate you enter. Actual returns may be higher or lower. SIPs reduce risk through rupee cost averaging but do not eliminate market risk.
