Calculation Methodology & Rules

1. Flat SIP Calculation Formula

For a standard SIP without annual step-up, the future value (FV) is computed using the monthly compounding formula (applied at the start of each month):

FV = P × [ ( (1 + i)n- 1 ) / i ] × (1 + i)

Where:

  • P: Monthly investment amount (₹)
  • i: Monthly interest rate (Expected annual return % / 12 / 100)
  • n: Total number of compounding periods (Years × 12)

2. Step-up SIP Compounding Method

For a Step-up SIP, the monthly contribution increases annually by your chosen **Annual Step-up (%)**. The calculator compounds the accumulated wealth month-by-month, applying the higher contribution at the beginning of each year.

3. Assumptions & Disclaimers

  • Timing of Contributions: Investments are assumed to occur at the start of each month (advance annuity model).
  • Assumed Return: Calculations assume a constant annual return rate. In practice, mutual fund returns vary based on market cycles.
  • Market Risk: Mutual fund investments are subject to market risks. Returns computed here are illustrative projections and not guaranteed.

Frequently Asked Questions

This calculator projects the future value of a Systematic Investment Plan (SIP) using the standard Future Value of an Annuity formula. It assumes regular monthly installments and monthly compounding at a constant rate of return. If you need to calculate the annualized return (yield) of your past, dated mutual fund transactions, you should use our XIRR Calculator.

A Step-up SIP (or top-up SIP) allows you to automatically increase your monthly investment amount by a fixed percentage or rupee value every year. This aligns your investments with salary hikes and significantly boosts your wealth compounding over long horizons.

A Systematic Investment Plan (SIP) is ideal for salaried individuals as it instills regular saving habits and leverages rupee-cost averaging to buffer against market volatility. Lumpsum investing is better when you have a large cash windfall (like a bonus, inheritance, or asset sale) and a long-term investment horizon to ride out short-term market corrections.
