Return on investment

-

  • Net gain-
  • Total cost basis-
  • Annualized return-

A simplified estimate. It does not model taxes, cash flows during the period, inflation, or investment risk.

Total ROI and annualized return answer different questions

Total ROI shows the gain relative to the full cost basis. Annualized return converts the whole-period change into an average compounded yearly rate, making different holding periods easier to compare.

ROI = (ending value - cost basis) / cost basis
Should fees be included?
Yes. Put acquisition, transaction, or other direct costs in the costs field.
Can ROI be negative?
Yes. An ending value below total cost produces a negative return.
What is an annual rate of return on investment calculator?
It is another name for an investment ROI calculator: enter your starting cost and ending value, plus any fees and the holding period, to see total return and the annualized rate. This ROI investment calculator shows both numbers side by side.

How it works

How the ROI Calculator works

Quick answer: Investing $10,000 (plus $100 of costs) that grows to $12,500 in 3 years is a +23.76% total return, or +7.37% a year annualized.

Formula

ROI = (ending value − cost basis) ÷ cost basis × 100
Annualized = (ending value ÷ cost basis)^(1 ÷ years) − 1

Cost basis is the initial investment plus extra costs such as fees or commissions.

Worked example

Basis $10,100, ending value $12,500. Net gain: $2,400. ROI: +23.76%. Annualized over 3 years: +7.37%.

$10,000 grows to $12,500; effect of holding period

Assumptions and limits

  • Annualized return lets you compare investments held for different lengths of time.
  • Dividends or income received along the way should be added to the ending value.
