It depends entirely on your gross margin. A 4× ROAS at 50% gross margin is comfortably profitable; a 4× ROAS at 20% margin is barely above break-even. Always interpret ROAS through the margin lens.

Should I optimize for ROAS or revenue?

Optimize for the highest profitable revenue you can get. Pure ROAS optimization caps growth (you stop scaling once efficiency dips); pure revenue optimization torches margin. The right answer is usually a target ROAS floor that lets you scale aggressively above it.

Why is my reported ROAS so different from my actual revenue?

Platforms count post-click and post-view conversions within their attribution windows, which often includes purchases that would have happened without the ad (incrementality bias). Reconciling against blended ROAS catches this gap.

What is a good ROAS?

Every founder eventually asks: what ROAS should we be hitting? The honest answer is that ROAS is a ratio without a fixed target. A 2× ROAS can be excellent for one business and a disaster for another. The number that matters is the relationship between ROAS and your gross margin.

The break-even formula

Break-even ROAS = 1 ÷ gross margin. A business with a 50% gross margin breaks even at 2× ROAS. A 25% margin business needs 4× just to break even on ad spend before any other costs.

'Good' ROAS is whatever clears break-even with enough room for fixed costs, retention work, and profit. A 3× ROAS in a 50% margin business is healthy; the same 3× in a 20% margin business is losing money.

Rough ranges by business type

These are starting points, not targets. Real benchmarks come from your own historical data once you have it.

DTC ecommerce (40–60% margin): 3×–5× is typical for healthy paid scale.
SaaS subscription (high margin, long LTV): blended ROAS can be < 1× and still be profitable over the customer lifetime.
Low-margin retail or marketplaces: often need 6×–10× just to be sustainable.
Lead-gen businesses: cost per qualified lead is usually a clearer target than ROAS until close rates are stable.

Why blended ROAS matters more than channel ROAS

Channel-level ROAS in Meta or Google Ads usually overstates incrementality — those platforms claim credit for purchases that would have happened anyway. Blended ROAS (total revenue ÷ total ad spend) is the honest number.

Use platform ROAS for relative comparisons; use blended ROAS for the actual business decision. A common pattern: Meta reports a 5× channel ROAS while the blended number is only 1.8×. That gap is incrementality — the share of those purchases the channel actually caused, versus those it merely tracked.

How ROAS evolves through the funnel

Top-of-funnel campaigns aimed at new audiences will almost always show lower ROAS than retargeting or brand campaigns. That's not a failure — it's how the funnel works.

Set distinct ROAS targets for prospecting and retargeting separately. Prospecting might target 1.5–2× and break even on a first purchase, knowing repeat revenue will pull the cohort into profit over the next 90 days. Retargeting might target 5–8× because it's harvesting demand that already exists.

Run the numbers

The ROAS / CAC / LTV calculator computes ROAS, CAC, and LTV:CAC together so you can see how the three move relative to each other. The Margin & Markup Calculator helps you confirm the gross margin number that drives the break-even ROAS calculation.

Summary

There is no universal good ROAS — only ROAS measured against your gross margin and the funnel stage of the campaign. Anchor your targets to break-even, separate prospecting from retargeting, and trust blended numbers over channel-reported ones when the two disagree.
