Break-Even ROAS Calculator

Before you spend a dollar on ads, know the return you actually need. This finds your break-even ROAS, the target ROAS for the profit you want, and the most you can afford to pay per sale and per click — straight from your margin.

Your economics

Average order value

Gross margin %

Gross margin = revenue minus the direct cost of the sale (product/materials, sub-labor) before ads and overhead. This is the pool ad spend comes out of.

Payment processing %

Desired profit %

Processing fees (~2.9%) eat into margin on every sale, so they're subtracted first. Desired profit is what you want left after ads — used for your target ROAS.

Ad performance (optional)

Conversion rate %

Your current ROAS (x)

Conversion rate unlocks your max cost-per-click. Enter your current ROAS (revenue ÷ ad spend) to see if your ads are actually profitable.

The highest ROAS is the lead you already paid for

Paid ads are the most expensive way to get a customer — and most of that spend leaks out when the resulting calls, texts, and form fills go unanswered. Capturing and instantly responding to the leads your ads already generate is pure ROAS upside, no extra budget required. That's what BizBot's verticals do.
