Business ROI Calculator

Enter the amount you spent and the amount it returned to get your business ROI as a percentage and the net gain. Add a time period to see the annualized rate for comparing projects.

Measure the return on a business spend as a percentage. Enter the amount you spent and the amount it returned to get the ROI and net gain, and add a time period for the annualized rate that lets you compare projects.

Cost & return

Return on investment

100.00%

$2,000.00 net gain

Net gain
$2,000.00
Annualized ROI
100.00%

ROI = (gain − cost) ÷ cost. This measures whether a spend paid off. To compare investment growth over time (start to end value, CAGR), use the investment return calculator.

How it works

  1. 1

    Enter the cost

    Add the amount spent on the campaign, project or purchase.

  2. 2

    Enter the return

    Add the total amount it brought back (revenue or value), not just the profit.

  3. 3

    Read the ROI

    See the ROI %, the net gain, and optionally the annualized rate over the period.

Frequently asked questions

How do you calculate ROI?
ROI = (gain − cost) ÷ cost, as a percentage. Subtract spend from return, divide by spend, then multiply by 100. A $4,000 return on a $2,000 cost is a 100% ROI.
What is the difference between ROI and ROAS?
ROI = (gain − cost) ÷ cost and measures net profitability. ROAS = revenue ÷ ad cost and ignores costs beyond ad spend. A 4x ROAS can still be a poor ROI once product, labor and fees are counted.
What is annualized ROI?
It converts a total return into a per-year rate so projects of different lengths compare fairly. A 50% return over two years is about 22.5% a year, while 50% in six months is far higher annualized.
Looking at investment growth over time instead?
For start-to-end value and CAGR on a held investment, use the investment return calculator. This tool is built for business spend, like a campaign or a project, paying off.
