ROAS Calculator

Return on ad spend (ROAS) is the revenue a campaign produces for each dollar spent on it. A 4.0x ROAS means every $1 of spend returned $4 of revenue. It is the headline efficiency number for paid media — the gauge of whether a channel earns its budget.

Because it is a ratio of revenue to spend, it is comparable across campaigns and budgets, which makes it the natural input to scaling and reallocation decisions.

The result is labelled against a healthy-paid benchmark so the number resolves into a decision:

Low — well under the benchmark; efficiency must improve before adding budget. Average — near the benchmark; scale carefully and keep testing. Strong — at or above the benchmark; the channel can absorb more spend while staying profitable.

ROAS measures revenue against ad spend; ROI measures profit against total cost. A campaign can post a strong ROAS yet thin ROI if margins or fulfilment costs are high. Always pair ROAS with your margin to find breakeven ROAS — the point below which extra spend loses money — before deciding to scale.

ROAS improves from both ends: lift conversion rate and average order value on the traffic ads deliver, and raise traffic quality through tighter targeting, better creative, and message-to-landing match. Cutting spend on segments converting below breakeven often lifts blended ROAS faster than any creative change. Model the revenue of each gain as a scenario above.

Holding spend constant isolates efficiency from budget. The scenario above shows what each additional point of ROAS is worth on the spend you already commit — revenue gained without a larger budget, which is the cleaner first move before scaling a channel.
