Advertising Break-Even Guide
Find break-even acquisition cost and return on ad spend from price and contribution margin.
Build a baseline, conservative case, and alternative
The calculator organizes assumptions. It does not replace a contract, tax determination, recommendation, or current market quote.
Start with source figures
Set an advertising ceiling from contribution after product, fulfillment, platform, payment, and expected refund costs—not from gross revenue.
- Use realized revenue after discounts.
- Include return and refund leakage.
- Recheck economics by channel and product.
Run more than one scenario
Save the documented baseline, then change the assumption most likely to move. If a small change reverses the decision, gather better information or preserve more margin.
Verify before acting
Use the advertising break-even calculator to create a comparable estimate, then reconcile important figures with the relevant statement, quote, contract, or official source.
