Formula

How mutual fund growth is calculated

Mutual fund growth is estimated by compounding your starting balance and contributions at an expected return, then reducing that return by expense ratio, tax drag, sales load, and inflation assumptions.

Net return = gross return − expense ratio − tax drag
Real return = ((1 + net return) ÷ (1 + inflation)) − 1

Planning note

Why expense ratios matter

Expense ratios reduce fund returns every year. A small annual fee difference can compound into a large final-value difference, especially over long SIP or retirement investing timelines.

Expense drag = no-fee future value − fee-adjusted future value
SIP corpus = recurring contributions compounded at net return

Questions

Frequently Asked Questions

What is a mutual fund calculator?

A mutual fund calculator estimates how an investment may grow over time using your starting amount, recurring contributions, expected return, expense ratio, tax drag, inflation, and investment period.

How does the SIP calculator work?

The SIP calculator compounds each recurring contribution at the expected net return. It can also include an annual step-up rate, so contributions increase over time.

Why does expense ratio matter?

The expense ratio reduces returns every year. Even a small difference can become significant because the fee drag compounds over long investing periods.

What is the difference between gross return and net return?

Gross return is the return before costs. Net return subtracts expense ratio and any tax drag, which gives a more realistic estimate of the investor’s actual return.

Can this calculator predict actual mutual fund returns?

No. The calculator uses assumptions for planning only. Actual mutual fund returns can vary with market performance, fees, taxes, portfolio risk, and investment timing.
