Calculate mutual fund SIP returns with step up percentage, annual lump sums, and CAGR and XIRR growth.
Add an extra monthly SIP amount for specific investment years.
Select months where an additional SIP installment is contributed (e.g. bonus months).
A Systematic Investment Plan (SIP) calculator is a financial tool that helps investors estimate the potential returns of recurring investments in mutual funds or stocks. Instead of depositing a single lump sum, a SIP allows you to invest fixed amounts at periodic intervals (usually monthly), leveraging dollar-cost averaging and compound growth over time. While basic calculators model flat monthly deposits, the Advance SIP Calculator lets you model real-world scenarios—such as annual salary increases (Step-Up SIP), year-end lump-sum bonuses, custom extra installments, and specific bonus-month contributions.
Calculating SIP returns requires compounding each monthly contribution separately based on the number of months it remains invested. Because early installments compound over a longer duration than later ones, the final portfolio value is the cumulative sum of all individually compounded monthly deposits. Using an online SIP calculator automates this calculation instantly across long multi-year investment horizons.
Under the hood, SIP investments follow the standard annuity-due compounding model, where contributions are made at the beginning of each payment period:
Monthly SIP Compounding Formula (Annuity Due):
where r = Expected Annual Return (%) / 1200 (Nominal Monthly Interest Rate)
Compound Annual Growth Rate (CAGR) measures the annualized point-to-point return for a single, one-time lump sum investment: CAGR = (Final Value / Initial Value)(1 / Years) - 1. However, because a monthly SIP involves multiple cash inflows occurring on different dates, standard CAGR cannot be directly applied. Instead, financial analysts use Extended Internal Rate of Return (XIRR) to accurately calculate the annualized rate of return across multiple periodic cash flows.
Stepping up your monthly contribution each year in tandem with annual salary raises or adding year-end bonus lump sums significantly accelerates wealth accumulation compared to a static SIP. The table below illustrates how modest annual step-ups compound over a 20-year period at an assumed 12% annual return starting with ₹10,000/month:
| SIP Strategy | Starting Monthly | Total Invested | Final Portfolio Value | Net Wealth Gained |
|---|---|---|---|---|
| Fixed SIP (0% Step-Up) | ₹10,000 | ₹24.0 Lakh | ₹99.91 Lakh | ₹75.91 Lakh |
| 10% Annual Step-Up | ₹10,000 | ₹68.7 Lakh | ₹1.989 Crore | ₹1.302 Crore |
| 15% Annual Step-Up | ₹10,000 | ₹1.23 Crore | ₹3.026 Crore | ₹1.798 Crore |
What is a SIP calculator and how does it work?
A SIP calculator is an online tool that estimates the future value of recurring periodic investments in mutual funds or stocks. You input your monthly contribution, expected annual return rate, and investment horizon, and the calculator applies monthly compounding math to show your total invested capital, expected returns, and overall portfolio wealth.
How to calculate SIP returns in mutual funds?
To calculate SIP returns in mutual funds, each monthly contribution is compounded individually using the nominal monthly rate r = Annual Return % / 1200. For any given month m, the new portfolio value is Portfolio(m) = (Portfolio(m-1) + Monthly Deposit) × (1 + r). Summing these compounded monthly balances across the entire investment period yields your total returns.
How is SIP calculated in an Advance SIP Calculator?
An Advance SIP Calculator models real-world financial flexibility by combining base monthly SIP deposits with annual step-up percentages, recurring yearly lump-sum top-ups, extra bonus-month contributions, and custom installment overrides. Each month's starting balance is compounded at (1 + r) based on the exact timeline of contributions.
How to calculate CAGR for SIP investments?
Standard CAGR applies to a single lump-sum investment measured from start to finish. Because a SIP involves recurring deposits made at regular intervals over time, financial institutions calculate annualized SIP performance using Extended Internal Rate of Return (XIRR), which computes the exact discount rate that equates the sum of all cash flows to the final portfolio value.
What is the difference between a Step-Up SIP calculator and a Lump Sum SIP calculator?
A Step-Up SIP calculator increases your recurring monthly deposit by a fixed percentage every year (matching annual salary increments), whereas a Lump Sum SIP calculator models one-time initial deposits or recurring annual bonus contributions alongside regular monthly installments.
