How to Use This Tool

Follow these steps to calculate your break-even ROAS:

  1. Enter your Cost of Goods Sold (COGS) as a percentage of total revenue. This is the direct cost to produce or source your product.
  2. Enter variable costs (shipping, transaction fees, marketplace fees) as a percentage of revenue. Leave at 0 if not applicable.
  3. Enter any fixed costs for the campaign, such as creative production or agency fees. Leave at 0 if none.
  4. Enter your total ad spend for the campaign. This must be a positive number.
  5. Select your currency from the dropdown menu.
  6. Click the Calculate Break-Even ROAS button to see your results.
  7. Use the Reset button to clear all fields and start over, or Copy Results to save your breakdown.

Formula and Logic

Break-even ROAS is the minimum return on ad spend required to cover all campaign costs and avoid losses. The calculation uses the following formula:

Break-Even ROAS = (Fixed Campaign Costs + Ad Spend) / (Ad Spend × (1 - COGS% - Variable Costs%))

We first calculate your gross margin by subtracting COGS and variable costs from 100% of revenue. This tells us how much of each dollar in revenue is available to cover fixed costs and ad spend. We then divide total campaign costs (fixed + ad spend) by the portion of ad spend that contributes to gross margin.

Required revenue to break even is calculated as Break-Even ROAS multiplied by Ad Spend. This is the total revenue your campaign needs to generate to cover all costs.

Practical Notes

For e-commerce sellers and marketers, keep these real-world factors in mind when using this tool:

  • COGS should include all direct costs tied to producing or sourcing your product, including raw materials, manufacturing, and import duties.
  • Variable costs often include payment processing fees (e.g., Stripe, PayPal), marketplace fees (e.g., Amazon, Shopify), and shipping costs per order.
  • Fixed costs should only include expenses directly tied to the campaign, such as ad creative design, influencer fees, or agency management costs. Do not include ongoing overhead like rent or salaries.
  • A break-even ROAS of 2x means you earn $2 in revenue for every $1 spent on ads to cover all costs. Most e-commerce campaigns aim for a ROAS of 3x or higher to generate meaningful profit.
  • If your variable costs plus COGS exceed 100%, your campaign will never be profitable, as you lose money on every sale before accounting for ad spend.

Why This Tool Is Useful

This calculator helps business owners and marketing teams make data-driven decisions about ad spend:

  • Set realistic ROAS targets for campaigns instead of guessing.
  • Compare the profitability of different products with varying COGS and variable costs.
  • Justify ad spend to stakeholders by showing the minimum performance required to break even.
  • Identify opportunities to lower break-even ROAS by reducing COGS, variable costs, or fixed campaign expenses.
  • Avoid overspending on ads that cannot generate enough revenue to cover costs.

Frequently Asked Questions

What is a good break-even ROAS for e-commerce?

A "good" break-even ROAS depends on your industry and product margins. For low-margin products (e.g., 20% gross margin), break-even ROAS may be 5x or higher. For high-margin products (e.g., 60% gross margin), break-even ROAS may be 1.67x or lower. Most e-commerce businesses aim for a target ROAS 20-30% above break-even to generate profit.

Does this calculator include taxes in the calculation?

No, this tool does not account for sales tax, VAT, or income tax. These are typically treated as separate expenses outside of campaign-specific costs. Consult your accountant to adjust your ROAS targets for tax obligations.

How do I calculate COGS for a service-based business?

For service businesses, COGS includes direct costs to deliver the service, such as labor, software subscriptions, or materials used for the service. Enter these costs as a percentage of service revenue to calculate your break-even ROAS for service ad campaigns.

Additional Guidance

To get the most accurate results from this tool:

  • Use historical data for COGS and variable costs instead of estimates where possible.
  • Update your fixed campaign costs if you add new expenses mid-campaign.
  • Track your actual ROAS against the break-even threshold using analytics tools like Google Analytics or Meta Ads Manager.
  • Re-calculate your break-even ROAS if you change suppliers (to lower COGS) or switch payment processors (to lower variable costs).
  • Remember that this tool calculates break-even, not profit. Add a buffer to your target ROAS to account for unexpected costs or lower-than-expected conversion rates.
