Enter conversion value and ad spend, and get your return on ad spend as a multiple, a percentage, and the profit or loss the campaign actually produced.
ROAS = conversion value ÷ ad spend. A 4.0x ROAS means every $1 of spend returned $4 of revenue — before margin. To find the ROAS where you stop losing money, use the break-even ROAS calculator.
Return on ad spend is the simplest ratio in paid media: ROAS = conversion value ÷ ad spend. Spend $3,200, drive $12,500 in tracked revenue, and your ROAS is 3.91x — or 391% if your client prefers percentages. Same number, two dialects.
There is no universal answer, because ROAS says nothing about margin. A 4x ROAS is a money printer on 70% margin software and a slow leak on 20% margin ecommerce. The only ROAS benchmark that matters is your own break-even: the point where revenue from ads equals the true cost of fulfilling those orders. Work that out with the break-even ROAS calculator, then set targets above it with room to breathe.
ROAS uses platform-tracked revenue, which flatters the channel that gets attribution. POAS (profit on ad spend) swaps revenue for profit; MER (marketing efficiency ratio) divides total revenue by total ad spend across channels. Use ROAS for in-platform optimization, MER for the monthly business conversation, and margin math for the decisions in between.
ROAS = conversion value ÷ ad spend. $12,500 in revenue on $3,200 of spend is a 3.91x ROAS, or 391% expressed as a percentage.
It depends entirely on your margin. A common rule of thumb is 4x for ecommerce, but a business with thin margins can lose money at 4x while a high-margin business profits at 2x. Calculate your break-even ROAS from real unit economics, then target above it.
No. ROAS compares revenue to ad spend and ignores every other cost. ROI compares profit to total investment. A campaign can have a strong ROAS and a negative ROI if margins are thin.
Work out the ROAS where a campaign stops losing money, from your real margins.
