How ROI is calculated

ROI = (Return − Cost) ÷ Cost × 100
Annualized ROI = ((1 + Total ROI) ^ (1 ÷ Years) − 1) × 100

Return on investment is one of the most widely used numbers in business because it’s flexible — the “investment” can be anything with a cost attached: an ad campaign, a piece of software, a certification, a hire, a new tool. The formula stays the same regardless of what you’re measuring; only what counts as “cost” and “return” changes.

Example

You spend $2,000 on a paid ad campaign that generates $5,000 in course sales. Net profit = $5,000 − $2,000 = $3,000. ROI = $3,000 ÷ $2,000 × 100 = 150%. For every $1 spent, you got $2.50 back.

Simple ROI vs. annualized ROI

Simple ROI treats the whole return as happening at once, which is fine for a short campaign but misleading for anything spanning multiple years. A investment that returns 50% over 3 years and one that returns 50% in 6 months are not equally good — the second is compounding much faster. Annualized ROI corrects for this by converting the total return into an equivalent year-over-year rate, which is the only fair way to compare investments with different timelines side by side.

What counts as “cost” and “return”

Be consistent about what you include on each side, or the number will mislead you. For cost, include everything spent to make the investment happen — not just the sticker price, but your own time if it was meaningful, any tools or software required, and any ongoing costs during the period measured. For return, count actual value generated: revenue, but also documented cost savings, retained customers who would otherwise have churned, or time saved that has a real dollar value. Vague or padded numbers on either side produce an ROI figure that looks impressive but doesn’t hold up to scrutiny.

Measuring a specific type of spend? If you’re looking at cost per customer across marketing channels, the Customer Acquisition Cost Calculator is built for that. If you’re evaluating an affiliate program specifically, the Affiliate Program ROI Calculator accounts for incrementality, which general ROI math skips.

Frequently asked questions

What is a good ROI?
It depends heavily on what you’re measuring and over what timeframe — there’s no single universal benchmark. For marketing spend, many businesses target at least 100% ROI (getting back double what was spent) as a rough baseline, but the right target for you depends on your margins, risk tolerance, and what alternative uses that money would have.
What’s the difference between ROI and profit margin?
ROI measures return relative to what was invested (Profit ÷ Cost). Profit margin measures profit relative to revenue (Profit ÷ Revenue). They answer different questions — ROI tells you if a specific spend was worth it, margin tells you how much of your total revenue is actually profit. The two numbers are related but not interchangeable.
How do I calculate ROI for content marketing?
Add up the cost of producing the content (your time or a writer’s fee, any tools, promotion spend) as your cost, and the revenue it’s directly generated or influenced as your return — this is harder to attribute cleanly than a paid ad, so many creators use a reasonable estimate based on traffic and conversion data rather than perfect attribution.
Should ROI include my own time?
If you want an honest number, yes — value your time at a reasonable hourly rate and add it to the cost side. Skipping this makes any investment that mostly costs “your time” look far more profitable than it actually is, since unpaid labor doesn’t show up as a cost otherwise.
Is a negative ROI always bad?
Not necessarily in every case — some investments (brand awareness, list building, a new offer’s first launch) are expected to run at a loss initially while building an asset that pays off later. But a negative ROI on something with no clear future payoff attached is a real signal to reconsider the spend.
