Updated August 1, 2026
ROAS (return on ad spend) is the revenue you earn for every dollar you put into ads. Enter your ad spend and the revenue it generated to get your ROAS instantly — then see what counts as a good ROAS and how to push it higher.
Calculate your ROAS
Your ROAS
4.00×
A solid, profitable range for most online stores.
For every $1 you spent on ads, you got 4.00× back in revenue.
How ROAS is calculated
ROAS = revenue from ads ÷ ad spend. Spend $500 and make $2,000 in attributed revenue and your ROAS is 2,000 ÷ 500 = 4.0× (often written 4:1 or 400%).
ROAS measures revenue, not profit. A 3× ROAS can be very profitable on a high-margin product and a loss on a low-margin one — always read it against your break-even ROAS (1 ÷ your gross margin).
What is a good ROAS?
A common rule of thumb is that 4× is healthy for ecommerce, but the only number that truly matters is your break-even ROAS — the point where a sale from ads stops losing money. If your gross margin is 40%, you break even at 2.5×; anything above that is profit.
So a "good" ROAS is one comfortably above your break-even, sustained as you scale. Chasing a very high ROAS often means underspending — you may make more total profit at a lower ROAS with far more volume.
How to improve your ROAS
Fix measurement first — if conversions are under-reported (iOS, cookie loss), your real ROAS is higher than the dashboard shows and you may be pausing winners. Server-side tracking recovers those sales.
Cut the losers and feed the winners — most accounts have a few ad sets quietly draining budget. Shifting spend to the profitable ones lifts blended ROAS without touching the offer.
This is the core of what Geniusko automates on Meta: it watches real ROAS per ad, pauses the drains and scales the winners daily — the work that keeps ROAS up as budgets grow.

What does ROAS mean?
ROAS stands for return on ad spend — the revenue generated for every unit of currency spent on advertising. A 4× ROAS means $4 in revenue for every $1 spent.
How do I calculate ROAS?
Divide the revenue attributed to your ads by the amount you spent on them. $2,000 revenue from $500 spend is a 4× ROAS. The calculator above does it instantly.
What is a good ROAS for Facebook ads?
There's no universal number — it depends on your margins. Calculate your break-even ROAS (1 ÷ gross margin) and treat anything comfortably above it as good. 3–4× is a common healthy target for ecommerce.
Is ROAS the same as profit?
No. ROAS is revenue over ad spend and ignores product cost, shipping and fees. A high ROAS on a thin-margin product can still lose money — always compare against your break-even ROAS.
