How the calculation works
Monthly growth factor = (1 + annual return / 100)^(1/12). Each month, apply that factor and add the contribution at the selected time.
Work through an example
With no starting amount, ₹1,000 invested each month for one year at a 0% return produces ₹12,000. A 10% annual step-up changes the monthly contribution to ₹1,100 in the second year. With a 0% return, the two-year total is ₹25,200.
Assumptions and limitations
The annual return is an effective annual assumption converted to a monthly rate. A step-up applies from month 13 and every 12 months after that. Returns are constant in this illustration; actual market returns vary. Taxes, fund fees, and exit loads are excluded.
The displayed defaults are examples, not live rates. Results are before tax unless explicitly stated. Figures are calculated at full precision, with amounts rounded for display, so adding displayed rows may differ by a small rounding amount.
Questions about this calculator
Are SIP returns guaranteed?
No. The result illustrates a constant assumed return, not a prediction or a fund recommendation.
Why can another SIP calculator show a different result?
Contribution timing and annual-to-monthly rate conversion can differ. This calculator uses an effective annual return and lets you select beginning or end of month.
Keep the comparison useful
Save one calculation before changing an input. Keep the other assumptions fixed, then compare the result with the saved calculation. For borrowing, look at the total interest and repayment time as well as the scheduled payment. For investing, compare contributions with growth and remember that a constant return is only an illustration.
