What is ROI (Return on Investment)?
ROI (Return on Investment) is the most universal financial metric for measuring investment profitability. It expresses, as a percentage, how much you gained (or lost) relative to what you invested. An ROI of 25% means that for every $100 invested, you get back $125. It's used in marketing, real estate, equipment purchases, stock investing, and any business decision involving an upfront outlay.
ROI formula
ROI (%) = ((Net profit − Investment cost) / Investment cost) × 100
Equivalently: ROI = (Total returns − Cost) / Cost × 100
A positive result means a profitable investment. A negative result means a loss.
Step-by-step example
You invest $2,000 in a social media ad campaign that generates $7,500 in sales, with $4,000 in product costs.
- Campaign net revenue: 7,500 − 4,000 = $3,500
- Net profit (after subtracting investment): 3,500 − 2,000 = $1,500
- ROI = (1,500 / 2,000) × 100 = 75%
Every dollar invested in the campaign generated $0.75 in net profit.
ROI applications by sector
- Digital marketing: Compare Google Ads, Meta Ads, email marketing, and SEO performance on equal terms.
- Real estate investing: Calculate whether annual rental income justifies the purchase price plus renovation costs.
- Stock market: Measure the true return of a stock portfolio, including dividends.
- Equipment investment: Determine in how many months a new machine pays for itself based on additional savings or revenue.
- Training and development: Companies measuring training ROI verify whether productivity gains justify the course cost.
ROI limitations and alternatives
- Doesn't account for time: 50% ROI over 10 years is very different from 50% in 1 year. For comparing investments over different timeframes, use annualized ROI or CAGR.
- Ignores risk: Two investments with the same expected ROI can have very different risk profiles.
- More complete alternatives: NPV (Net Present Value), IRR (Internal Rate of Return), and Payback Period offer a fuller picture for complex or long-term projects.
