Break-even ROAS Calculator

Use this calculator to find the minimum ROAS your campaigns need in order to avoid losing money (or to hit a target profit margin).

Average Order Value (AOV) ($)

Cost of Goods Sold per Order ($)

Shipping & Fulfillment per Order ($)

Payment Processing Fee (% of revenue)

Refund / Chargeback Rate (% of revenue)

Other Variable Costs (% of revenue)

Target Net Profit Margin (% of revenue)

Site Conversion Rate (%) (optional for break-even CPC)

Current ROAS (optional for status check)

ROAS = Revenue ÷ Ad Spend. Example: $300 revenue on $100 ad spend = 3.0 ROAS.

What is break-even ROAS?

Break-even ROAS is the exact return on ad spend where your business neither makes nor loses money on a sale after accounting for product costs, fees, shipping, refunds, and your profit goal. If your actual ROAS is below this number, your ads are unprofitable. If it is above, you are profitable.

Why this metric matters

Many advertisers focus only on top-line revenue. But revenue without margin can hide losses. Break-even ROAS helps you make decisions based on unit economics. It is useful for ecommerce brands, lead-generation businesses, agencies, and anyone managing paid traffic on platforms like Google Ads, Meta Ads, TikTok, or Pinterest.

Set realistic campaign targets before you launch.
Decide whether scaling spend is safe.
Compare products with different margins.
Know how much room you have for creative testing and bid volatility.

The core formula

The calculator uses this logic:

Available Ad Spend per Order = AOV − Fixed Variable Costs − Percentage-Based Costs − Target Profit
Break-even ROAS = AOV ÷ Available Ad Spend per Order

Percentage-based costs include items like processing fees, refunds, or royalties. If your available ad spend becomes zero or negative, no ad platform can save that offer until you improve pricing or reduce costs.

How to use this calculator correctly

1) Start with real averages

Use last 30–90 days of data for AOV, refund rate, and variable costs. Avoid using one exceptional week.

2) Separate variable and fixed overhead

This tool focuses on per-order economics. Include costs that change with each sale. Broader overhead (rent, salaries, software stack) can be handled in a deeper profit model.

3) Add a target margin, not just break-even

True operators rarely want “zero profit.” If you need 10% net margin, add it in the target field so your ROAS threshold reflects reality.

4) Validate with blended numbers

Channel-level ROAS may look good while blended business ROAS looks weak. Compare both.

Quick interpretation guide

Lower break-even ROAS (e.g., 1.5–2.0): healthier unit economics, easier scaling.
Medium break-even ROAS (e.g., 2.1–3.0): workable but requires solid creative and conversion rates.
High break-even ROAS (3.1+): fragile model; may need pricing, offer, or cost improvements.

How to lower your break-even ROAS

If your required ROAS is too high, improve the inputs instead of forcing the ad account:

Increase AOV via bundles, quantity breaks, and upsells.
Negotiate COGS, freight, and pick/pack rates.
Reduce refund rates with better qualification and onboarding.
Improve conversion rate through stronger landing pages and offers.
Increase retention so first-order acquisition can tolerate lower front-end margin.

Common mistakes to avoid

Using list price instead of realized AOV after discounts.
Ignoring payment fees and refunds.
Comparing one-day ad attribution to seven-day business outcomes.
Assuming the same break-even point for all SKUs.

Final thought

Break-even ROAS is one of the fastest ways to improve decision quality in paid acquisition. Once you know your true threshold, bidding, budgeting, and creative strategy become much clearer. Use this calculator regularly as costs and conversion performance change.
