Enter monthly investment amount, expected annual return, and investment period in years or months to estimate maturity amount, total invested, and projected returns, with an invested versus returns breakdown.
Enter your monthly investment amount, expected annual return (%), optional annual fee %, and investment period in years or months. Review the projected maturity value, total invested, estimated returns, and fee drag.
Example: investing $500/month at an expected 10% annual return for 15 years projects a maturity value of about $207,000, with $90,000 invested and roughly $117,000 in estimated returns. A 1% fee reduces that maturity amount.
The SIP calculator estimates the future value of fixed monthly investments using the standard systematic investment plan formula. It converts the expected annual return to a monthly rate and the investment period into monthly contributions, then projects maturity amount, total invested, and estimated returns. An optional annual fee % reduces the net return to illustrate fee drag. Market volatility and taxes are not included.
SIP projections use steady returns and regular contributions. Actual mutual fund returns vary and are not guaranteed.
