SIP Calculator: Systematic Investment Plan Return Estimator
A Systematic Investment Plan (SIP) allows individuals to invest a fixed sum at regular intervals (typically monthly) into mutual funds. Use our interactive engine below to calculate projected maturity wealth, experiment with annual step-up hikes, and adjust for inflation.

Final: ₹50.5 LThe Mathematics Behind Mutual Fund SIPs
SIP returns follow an annuity compounding formula where each individual monthly instalment earns compound interest for the exact number of months it remains invested:
The fixed monthly amount debited from your bank account.
Expected annual rate divided by 12 and 100 (e.g. 12% ÷ 1200 = 0.01).
Number of monthly payments (tenure in years × 12).
Worked Real-World Scenarios
Example 1: ₹10,000/Month for 15 Years at 12% Expected Return
Investing ₹10,000 every month for 15 years results in a personal contribution of ₹18 Lakh. At a historical Indian equity return rate of 12% p.a., your total corpus reaches over ₹50.45 Lakh, with compound growth providing nearly double your principal investment.
Example 2: The ₹1.5 Crore Goal (₹15,000/Month for 20 Years at 12%)
Starting a ₹15,000 monthly SIP at age 28 reaches ₹1.498 Crore by age 48. Notice the compounding hockey stick: you invested ₹36 Lakh, but created over ₹1.13 Crore in pure compounding gain.
Example 3: Step-Up SIP (₹10,000/Month + 10% Annual Salary Hike)
By stepping up your investment by 10% every year to match your annual corporate increment, your 15-year maturity value jumps from ₹50.45 Lakh to over ₹82.8 Lakh—nearly 64% more wealth created with painless incremental savings.
Two Core Pillars of SIP Investing
1. Rupee Cost Averaging
When market prices dip, your fixed monthly allocation automatically purchases more fund units at discounted Net Asset Values (NAV). When prices climb, fewer units are bought. Over market cycles, this averages down your acquisition cost without needing to time market tops and bottoms.
2. The Exponential Compounding Curve
Notice in our yearly growth schedule that during years 1 to 5, the total value grows linearly. However, between years 10 and 20, returns begin generating their own returns, creating an exponential upward curve where annual returns dwarf your fresh annual deposits.
Frequently Asked Questions
What return percentage should I reasonably assume for an equity SIP?
Historically over rolling 10-15 year horizons, broad-market Indian equities (Nifty 50 and SENSEX) have delivered between 11% to 13% CAGR. Conservative financial planners suggest modeling at 10%–12% to maintain a margin of safety against inflation.
How are mutual fund SIP gains taxed in India?
For equity mutual funds held for more than 12 months, long-term capital gains (LTCG) above ₹1.25 Lakh per financial year are taxed at 12.5% (effective Union Budget 2024–2026 revisions). Short-term gains (under 12 months) are taxed at 20%. Each monthly SIP instalment has its own individual 12-month holding period.
Can I pause or stop my SIP anytime?
Yes. Mutual fund SIPs in open-ended schemes do not lock your funds (unlike ELSS which has a statutory 3-year lock-in). You can pause, increase, or cancel your automated bank mandate at zero penalty.
