What Is a Good ROAS? Benchmarks & How to Calculate It (2026)

A good ROAS is generally 4:1 — $4 of revenue for every $1 of ad spend (a 400% return) — but that's a rule of thumb, not a law. Your real target is your break-even ROAS, and it's set entirely by your profit margin. Here's how to find the number that actually matters for your business, with the math worked out and a free ROAS calculator to run your own figures.

The quick answer, and why "4×" is only a starting point

4× is the number most agencies quote because it comfortably covers ad costs plus the other costs of running a typical retail business. But a company with 70% margins can thrive at 2×, while a thin-margin reseller can lose money at 5×. Enter your revenue and ad spend in the ROAS Calculator (revenue ÷ ad spend) to see where you stand right now — then read on to find your target.

Calculate your break-even ROAS

Break-even ROAS is simply 1 ÷ profit margin. Below it you lose money on every sale; above it you profit:

• 50% margin → break-even at 2×
• 33% margin → break-even at 3×
• 25% margin → break-even at 4×
• 20% margin → break-even at 5×

Not sure of your margin? Work it out from price and cost with the Profit Margin Calculator, then aim comfortably above break-even for a real profit target.

ROAS benchmarks by channel (2026)

• Google Search: high intent, often 4×–8× on branded and bottom-funnel terms.
• Google Shopping / Performance Max: commonly 3×–5× for established stores.
• Meta (Facebook & Instagram): 2×–4× is typical — prospecting runs lower, retargeting higher.
• TikTok: usually a lower ROAS but cheaper reach; judge it on blended results, not in isolation.

Treat these as sanity checks, not goals. A 3× campaign at 60% margin beats a 6× campaign at 15% margin every time.

ROAS vs ROI — don't confuse them

ROAS counts only revenue against ad spend; ROI accounts for all costs and reports profit. ROAS is the fast channel-level health check, ROI is the whole-business truth. Run both with the ROAS Calculator and the ROI Calculator, and watch your cost per acquisition so a "good" ROAS isn't hiding an unsustainable CAC.

How to improve a low ROAS

• Raise conversion rate — a better landing page lifts revenue without extra spend. Track it with the Conversion Rate Calculator.
• Cut wasted spend — add negative keywords, pause dead placements, tighten audiences.
• Lift average order value — bundles and upsells grow the revenue side of the ratio.
• Fix attribution — under-counted conversions make a healthy campaign look broken.

Bottom line

Aim for 4× if you need a starting target, but calculate your break-even from your margin and set your real goal above it. Run your numbers free — no sign-up, instant result.
