Systematic Investment Plan (SIP) Calculator

The SIP calculator projects future investment value and compares a Systematic Investment Plan (SIP) against a lumpsum investment on the same terms. An amount, expected annual return, and investment period project total value, estimated returns, and invested principal for either strategy. Advanced settings extend the model to a step-up SIP, contribution pauses, additional one-time investments, a market correction, inflation, and taxes, all of which shift the same projection rather than requiring a separate calculation.

SIP and Lumpsum are the two strategies compared, using the same investment amount, expected annual return percentage, and number of years as the baseline for either one. Advanced Settings extends that baseline with an optional annual step-up, pause months, lumpsum additions by year, a market correction, inflation, and a tax rate applied to returns. Invested Amount, Estimated Returns, and Total Value follow from those inputs, alongside a chart breaking the projection down visually. Inputs are saved automatically between visits for revisiting a scenario later.

Invested Amount shows total contributions from monthly SIPs and any lumpsum deposits. Estimated Returns reflects growth from compounding after optional inflation and tax adjustments. Total Value equals principal plus returns at the end of the selected period. Enabling inflation converts the projection into today's purchasing power. Setting a tax rate applies it to gains only, then recomputes the total. Comparing these outputs across strategies is how a contribution level gets checked against a target goal.

SIP example: Contributing $300 per month for 10 years at a 10 percent expected return, with a 5 percent annual step-up added to the contribution, shows the invested amount increasing each year while compounding expands the return's share of the total over time.

Lumpsum example: Investing $15,000 for 8 years at an 8 percent expected return, with a $3,000 lumpsum added in year 3 and a 15 percent market correction simulated in year 2, shows the recovery path and the final value with and without the added deposit.

What return rate should I use? A reasonable long-term expectation for the chosen asset class, based on historical data rather than recent short-term performance, works best, adjusted for individual risk tolerance.

How does a step-up SIP work? The monthly contribution increases each year by the step-up percentage, which raises both total invested principal and the potential compounding effect.

What does the market correction do? The specified drop applies to the portfolio at the end of the chosen year, and compounding continues from the new, lower level.

Does this provide advice? No. The projections serve education and planning only. A qualified advisor should be consulted before investing.

• Build disciplined savings by investing a fixed monthly amount that grows through compounding.
• Manage market volatility with dollar cost averaging when prices rise and fall.
• Plan for goals such as retirement, education, or a home down payment on a set timeline.
• Increase contributions with a step-up SIP to keep pace with income growth or inflation.

• Deploy windfalls from bonuses, inheritances, or asset sales in a single transaction.
• Act on opportunities during market declines or when valuations look attractive.
• Front-load investments early in the year to maximize time in the market.
• Combine strategies by adding periodic lumpsum contributions on top of an ongoing SIP.

A typical SIP calculator uses a compound interest formula to estimate the maturity value of regular monthly investments.

The formula is: M = P × ({[1 + i]^n - 1} / i) × (1 + i)

Where:

• M is the maturity amount
• P is the monthly investment amount
• i is the monthly interest rate (annual rate divided by 12)
• n is the total number of payments (months)

Investing ₹1,000 monthly for 12 months at an annual return of 12% (1% monthly) yields an estimated maturity value of ₹12,809.

Actual returns may vary based on market performance.
