ROI Calculator
Return on investment is the universal scorecard for a campaign or project: for every dollar in, how many came back? Enter what you earned and what you spent to see ROI, net profit, and where the money went.
ROI is only as honest as its inputs
The formula is trivial. The hard part is counting every cost and attributing revenue fairly — the two places ROI math quietly lies.
Count every cost
Media spend is the obvious line. Agency fees, production, tooling, and the time your team spent are the costs that turn a “3× return” into a break-even campaign once they’re included.
Attribution decides the number
ROI depends on which revenue you credit to the investment. Last-click flatters paid search; first-touch flatters awareness. State your attribution model alongside the ROI or the number is meaningless.
Pick the right horizon
A campaign that loses money in month one but builds a customer base can have a strong 12-month ROI. Match the measurement window to how long the value actually accrues.
Calculate your ROI
Enter the revenue generated and the total cost to see your return.
Total revenue attributable to the investment.
Everything you put in — media, fees, production, time.
Waiting for input
Enter revenue and cost to see your return on investment.
Formula: ROI = (revenue − cost) ÷ cost × 100. Net profit = revenue − cost.
What is ROI?
Return on investment expresses net gain as a percentage of what you put in. An ROI of 100% means you doubled your money; 0% means you broke even; negative means you lost money.
ROI is deliberately unit-free, which makes it the lingua franca for comparing very different investments — a campaign, a hire, a piece of software — on the same scale.
Calculate ROI
ROI = (Revenue − Cost) ÷ Cost × 100
Earn $30,000 from a $10,000 spend → ROI = (30,000 − 10,000) ÷ 10,000 × 100 = 200%
Net profit
Net profit = Revenue − Cost
$30,000 − $10,000 = $20,000
How to use this ROI calculator
Total up every cost
Include media, fees, production, software, and a fair estimate of internal time. The most common ROI error is undercounting cost.
Attribute revenue consistently
Use one attribution model and apply it to every campaign you compare. Mixing models makes ROI comparisons worthless.
Read ROI next to ROAS
ROAS measures gross return on ad spend alone; ROI measures net return on all costs. ROAS can look great while ROI is negative once fees and margin are in.
What is the difference between ROI and ROAS?
ROAS is gross revenue divided by ad spend only — a quick media-efficiency signal. ROI is net profit divided by total cost, including fees, production, and margin. ROAS can be 4× while ROI is negative once all costs and product margin are counted.
What is a good ROI?
Context-dependent. For a marketing campaign, a positive ROI after all costs is the floor; 2×–5× is healthy depending on margin. The real benchmark is your blended cost of capital and the next-best use of the same money.
Should ROI use revenue or profit?
For a strict return calculation, the numerator should be the gain net of the cost being measured. Many marketers use revenue for simplicity, but if your product margin is thin, use gross-profit-based ROI to avoid celebrating unprofitable growth.
One metric is a number — Multiply connects them all
When every campaign metric, brief, and account signal lives in one AI operating system, you stop calculating in spreadsheets and start acting on the full picture. That's Multiply.
