ROAS Break Even Calculator

What is break-even ROAS?

ROAS (Return On Ad Spend) measures the revenue generated for every dollar spent on advertising. A ROAS of 3 means $3 of revenue per $1 of ads. But a ROAS of 3 is meaningless on its own: profitable for one store, a disaster for another. What decides it is your break-even ROAS — the exact ROAS at which a campaign stops losing money.

Below your break-even ROAS, every sale costs you money. Above it, every sale contributes profit. It is the single most important number to know before launching any Meta Ads or TikTok Ads campaign.

Break-even ROAS formula: how is it calculated?

The formula is simple:

• Break-even ROAS = Selling price ÷ Profit per sale before ads

where profit before ads = selling price − product cost − shipping − transaction fees. The calculator also derives your break-even CPA (Cost Per Acquisition) — the maximum you can pay for one customer before losing money:

• Break-even CPA = Profit per sale before ad spend

Break-even ROAS examples

Example 1 — A healthy margin

• Selling price: $50
• Product + shipping + fees: $20

Profit before ads = $30. Break-even ROAS = 50 ÷ 30 ≈ 1.67, break-even CPA = $30. Any campaign above a 1.67 ROAS makes money — a very comfortable position.

Example 2 — A tight margin

• Selling price: $30
• Product + shipping + fees: $22

Profit before ads = $8. Break-even ROAS = 30 ÷ 8 = 3.75, break-even CPA = $8. This store needs an excellent campaign just to break even — most accounts can't sustain a 3.75+ ROAS at scale.

How to use the ROAS break-even calculator?

1. Choose your currency ($, € or £).
2. Selling price — what the customer pays.
3. Product cost — your unit cost.
4. Other costs per sale — shipping, payment fees, packaging.

The calculator instantly returns your break-even ROAS and your break-even CPA. Compare them with the actual figures in your ads manager: any campaign below the line is burning cash.

What is a good ROAS in e-commerce?

• ROAS below break-even: losing money — fix the offer or kill the campaign.
• ROAS at 1–1.5× break-even: profitable but tight — optimize creatives and AOV.
• ROAS at 1.5–2× break-even: solid — ready to scale progressively.
• ROAS above 2× break-even: excellent — scale aggressively while it lasts.

The takeaway: never judge a ROAS in absolute terms. A 2.5 ROAS is great with a 1.6 break-even and catastrophic with a 3.75 break-even.

How to lower your break-even ROAS?

1. Increase your margin — negotiate product costs or raise your price; both lower the ROAS you need (margin calculator).
2. Raise average order value — bundles and upsells raise revenue per purchase without raising acquisition cost.
3. Improve conversion rate — a better product page turns the same clicks into more sales.
4. Test stronger creatives — the fastest ROAS lever; find angles that already work with our Hook Generator.
