How this is worked out
  • CPM = (spend / impressions) x 1,000. CPC = spend / clicks. CPA = spend / conversions.
  • ROAS = revenue / spend. Click-through rate = clicks / impressions. Conversion rate = conversions / clicks.
  • Profit after ads = (revenue x margin) - spend.
  • Break-even ROAS = 1 / margin, so a 40% margin needs 2.5x.

How it works

1

Enter what the campaign did

Spend, impressions, clicks, conversions and revenue. Every ad platform reports these five.

2

Every rate is worked out at once

CPM, CPC, CPA, ROAS, click-through rate and conversion rate, so you can paste one row of numbers and read the whole picture.

3

Check it against your break-even

The break-even ROAS tells you the return you need for the campaign to wash its face, based on your margin.

Questions

It depends entirely on margin. At a 50% margin you need 2x to break even, so 3x is healthy. At a 20% margin you need 5x just to stand still. The break-even figure here does that arithmetic for you.

CPM is what a thousand people seeing your ad costs. CPC is what one click costs. CPA is what one customer costs. Going down that list moves from attention to money.

Not by itself. Display and video ads often sit under 1%, while brand search ads can pass 10%. Compare a campaign against its own history rather than a generic benchmark.

Use revenue after returns and discounts if you can. Otherwise the ROAS flatters the campaign.

Add UTM parameters to every link; the UTM link builder makes them in one step. To plan the spend itself, the ad budget calculator shows the clicks and customers a budget buys.
