Measure the return on any investment
Return on investment (ROI) is the simplest way to see how well an investment performed. Use it for shares, property, a business project, equipment or an ad campaign.
ROI formulas
ROI = (Final value − Invested) ÷ Invested × 100
Annualized ROI = (Final value ÷ Invested)^(1 ÷ years) − 1
Why annualized ROI matters
| Investment | Total ROI | Years held | Annualized |
|---|---|---|---|
| A | 45% | 3 | 13.2% |
| B | 60% | 6 | 8.1% |
Investment B has the higher total ROI, but A earned more per year.
ROI for marketing
For a campaign, use the cost of the campaign as the amount invested and the profit it generated (not revenue) plus that cost as the amount returned. Revenue alone overstates ROI.
