ROAS calculator.

A 3x ROAS means nothing on its own. This works out the ROAS you actually need — after product cost, shipping and payment fees — and whether the campaign in front of you is making money or quietly burning it.

How this is calculated

Every figure runs in your browser from the numbers you typed. Nothing is estimated.

ROAS
revenue ÷ ad spend
Contribution margin
revenue − (orders × (product cost + shipping)) − (revenue × platform fee %)
Breakeven ROAS
1 ÷ (contribution margin ÷ revenue)
The ROAS at which you make exactly nothing. Below it, every extra dollar of ad spend loses money.
Profit ROAS
contribution margin ÷ ad spend
Dollars of real margin per ad dollar. Above 1.0x you are profitable — a headline 3x ROAS can still sit below 1.0x here if the product costs too much to source.
ACOS
ad spend ÷ revenue × 100 — the inverse of ROAS
Your cost-per-order ceiling
AOV − product cost − shipping − (AOV × platform fee %)
The most you can pay to acquire one order and still break even. Use it as the cap on your target CPA.

Not included: returns, chargebacks, refunds, staff, apps and subscriptions. Those come out of the net profit above, so treat this as the ceiling rather than the take-home.

Stop finding out after the ad spend

Dropship Spy researches a product against current demand, sourcing, pricing, competition and risk data, then hands you a verdict with the evidence behind it — before you build the campaign. Then it writes and renders the ad, and builds the landing page.
