How marketing ROI and ROAS work

ROI (Return on Investment)

(Revenue - Spend) / Spend × 100

Measures profitability. 100% ROI means you doubled your money. Negative ROI means you lost money.

ROAS (Return on Ad Spend)

Revenue / Spend

Measures revenue generated per dollar spent. A 3.0x ROAS means $3 revenue for every $1 spent.

Break-even point

ROI = 0% / ROAS = 1.0x

You make back exactly what you spent. Anything above is profit, anything below is a loss.

The problem with manual ROI tracking

This calculator requires you to manually input revenue per channel. But how do you know which channel generated which revenue? That's the attribution problem — and it's what Attrifast solves automatically.

Automate this with Attrifast

Connect your Stripe account and Attrifast automatically tracks revenue per channel, per page, and per UTM campaign. No spreadsheets, no guessing, no manual data entry.
