Breakeven Ad ROAS Calculator
Calculate the minimum return on ad spend (ROAS) required to break even on advertising. Enter your product cost, selling price, shipping, fees, and other costs to determine the threshold ROAS needed to avoid losses on ads.
Enter your selling price and all costs except advertising. This calculator determines the minimum ROAS required to avoid a loss on advertising.

Formula
Breakeven ROAS = Selling Price ÷ (Selling Price − All Costs Except Ads) = 1 ÷ Profit Margin Before Ads
Breakeven ROAS is the minimum return on advertising spend required to avoid a loss. It tells you how many dollars of revenue you must generate for every dollar spent on ads to break even on that advertising spend. A breakeven ROAS of 3× means you must earn $3 in revenue for every $1 spent on ads.
Worked Example
Product selling price: $50 · Product cost: $15 · Shipping: $5 · Platform fee: 3% · Other costs: $2
Selling price: $50
Product cost: $15
Shipping: $5
Platform fee (3% of $50): $1.50
Other costs: $2
Total costs: $23.50
Profit before ads: $50 − $23.50 = $26.50
Profit margin before ads: $26.50 ÷ $50 = 53%
Breakeven ROAS: $50 ÷ $26.50 = 1.89×
Maximum ad cost per unit: $26.50
You need to earn $1.89 in revenue per $1 spent on ads to break even. If you spend $10 on ads, you must generate $18.90 in revenue. You can afford up to $26.50 per unit in ad spend while still breaking even.

Common mistakes
- ✕Forgetting to include all costs (platform fees, customer service, returns, packaging) — breakeven will be artificially low
- ✕Using an outdated selling price or cost structure — recalculate when prices or costs change
- ✕Confusing breakeven ROAS with target ROAS — breakeven is minimum; target should be higher for profit
- ✕Using breakeven ROAS for products with negative margins — you cannot profitably advertise a product sold at a loss
Responsible use note
This calculator helps you understand your break-even point for advertising. Achieving breakeven ROAS means zero profit on ad spend — you still need to earn above breakeven to be truly profitable. Always set target ROAS above breakeven to build sustainable margins. This is for planning purposes only and not financial or investment advice.
Frequently asked questions
How is breakeven ROAS different from actual ROAS?
Breakeven ROAS is a target or threshold you calculate based on your costs. Actual ROAS is measured from real advertising campaigns (revenue ÷ ad spend). Compare actual ROAS to breakeven ROAS to determine profitability.
What breakeven ROAS should I aim for?
Aim for a target ROAS well above breakeven. For example, if breakeven is 2×, target 3.5× to 4× for healthy margins. The higher above breakeven, the more profit you generate per dollar spent on ads.
Why does my breakeven ROAS feel high?
A high breakeven ROAS usually means low product margin. Check that you have included all costs: COGS, shipping, platform fees, returns, customer service, packaging, and other overhead. If margins are genuinely thin, raise prices or negotiate lower costs.
Can I change my breakeven ROAS by changing prices?
Yes. Raising your selling price (without changing costs) lowers your breakeven ROAS. Lowering costs also lowers breakeven ROAS. Either approach gives you more room for profitable ad spend.
Should I calculate breakeven ROAS per product or across all products?
Calculate for each product or product category if they have different margins. High-margin products support more ad spend; low-margin products support less. Use the most conservative (highest) breakeven ROAS if you run mixed campaigns.
