What counts as a good ROAS for a small business
A break-even ROAS for most small businesses is 2:1 to 4:1 once costs are included. A 'good' ROAS is whatever clears your margin, not a fixed number.

What's a good ROAS for a small business?
ROAS (return on ad spend) of 4:1 is a commonly quoted benchmark, but the right number depends entirely on your margin: with a 25% gross margin you need roughly 4:1 just to break even, while a 60% margin business can be profitable at 2:1. Ecommerce with thin margins often needs 3-5:1; SaaS with high margins and long customer lifetime can work with 1-2:1 if payback period is reasonable.

| Gross margin | Break-even ROAS | Comfortable target |
|---|---|---|
| 20% | 5:1 | 6-7:1 |
| 30% | 3.3:1 | 4-5:1 |
| 40% | 2.5:1 | 3-4:1 |
| 50% | 2:1 | 2.5-3:1 |
| 70% | 1.4:1 | 2-2.5:1 |
| 85%+ (typical SaaS) | 1.2:1 | 1.5-2:1 plus payback under 12mo |
Do this
The steps, in order.
- Step 1
Calculate your actual gross margin first
Take (revenue minus cost of goods or delivery) divided by revenue. Most people benchmark ROAS against a generic '4:1 is good' number without checking whether their own margin needs 3:1 or 6:1 to be profitable.
- Step 2
Decide if you're measuring first-order or lifetime value
First-order ROAS only counts the initial sale. If customers repeat-purchase or subscribe, a 1.5:1 first-order ROAS can be very profitable once you factor in the second and third purchase.
- Step 3
Include all ad-related costs, not just media spend
Add platform fees, agency fees, and creative production cost into the 'spend' side. A ROAS calculated on media spend alone overstates real profitability by 15-30% once fees are included.
- Step 4
Set your target ROAS in writing before the campaign
Work out the number using your margin, then treat campaigns below it as needing a fix, not as automatically failing — sometimes the fix is the offer, not the channel.
- Step 5
Track ROAS trend over 4-6 weeks, not day-to-day
Daily ROAS swings 50%+ on small budgets purely from sample size. Look at the 2-week rolling average to judge whether a campaign is actually improving or declining.
Worth knowing
The bits people get wrong.
ROAS gets quoted as a single benchmark number far more often than it should be, because the same ROAS means very different things depending on margin. A 4:1 ROAS on a product with 20% margin is barely break-even; the same 4:1 on a SaaS product with 85% margin is highly profitable.
For subscription or repeat-purchase businesses, first-order ROAS understates the real return, because it ignores renewals and repeat orders. It's usually worth calculating a second number — ROAS including 6 or 12 months of expected repeat revenue — alongside the first-order figure, especially before deciding a channel 'doesn't work'.
Platforms report ROAS with their own attribution logic, which since Apple's iOS privacy changes in 2021 has become noticeably less reliable, particularly on Meta. Treat platform-reported ROAS as directional rather than exact, and check it periodically against your own order data or a coupon/UTM-based estimate.
For a small business just starting with paid ads, a reasonable approach is to set a target ROAS from your margin math, accept the first month may miss it while the account is learning, and expect steady improvement by week 6-8 as targeting and creative get refined.
Questions
Follow-up questions.
Is 2:1 ROAS good or bad?
It depends on margin. For a business with 60%+ gross margin, 2:1 can be solidly profitable. For a business with 25% margin, 2:1 is a loss once costs of goods are included.
Why does my ROAS look worse since iOS 14?
Apple's App Tracking Transparency changes reduced how much conversion data platforms can see, especially on Meta, so reported ROAS is often understated compared to your actual sales. Cross-check with your own order data.
What ROAS should a new campaign target in month one?
Set the break-even number from your margin, then expect month one to land 20-40% below it while the account learns. Judge the real trajectory at 6-8 weeks, not week one.
Should I include shipping and returns in the ROAS calculation for ecommerce?
Yes, for a true profitability view. Media-spend-only ROAS ignores shipping, returns and payment processing, which can be 15-25% of revenue and change whether a campaign is actually profitable.
Is ROAS the right metric for a B2B business?
Not usually on its own — B2B sales cycles are long, so first-touch ROAS from ad platforms rarely reflects the eventual deal. Cost-per-qualified-lead and pipeline generated are usually more useful.
