How marketing ROI and ROAS work
ROI (Return on Investment)
(Revenue - Spend) / Spend × 100Measures profitability. 100% ROI means you doubled your money. Negative ROI means you lost money.
ROAS (Return on Ad Spend)
Revenue / SpendMeasures revenue generated per dollar spent. A 3.0x ROAS means $3 revenue for every $1 spent.
Break-even point
ROI = 0% / ROAS = 1.0xYou make back exactly what you spent. Anything above is profit, anything below is a loss.
