Plan daily and monthly ad spend from target orders, expected CPA and your break-even economics — without assuming one universal Meta, TikTok or Google Ads budget.
Use the maximum CPA from the Break-even ROAS calculator.
Optional profit-preserving CPA target.
A simple testing reference: expected CPA × chosen multiple. This is not a platform rule.
The calculator starts with the number of paid orders you want and multiplies that by your expected cost per acquisition. It then compares the expected CPA with your break-even and profit-preserving CPA limits.
A campaign can technically spend the requested budget and still be economically weak. That is why the calculator shows both the spend required for your order target and whether your expected CPA is below the maximum CPA your product can support.
The test-budget reference multiplies expected CPA by a user-selected number of conversions. It is simply a planning shortcut for estimating how much daily budget might allow several conversion opportunities. It is not an optimization rule from Meta, TikTok or Google.
Not necessarily. The monthly figure shows what the target order volume would require if CPA stayed near your assumption. New campaigns are usually tested and adjusted as real performance data arrives.
Then the modeled paid order loses money before overhead. Improve acquisition efficiency, increase price, or reduce non-ad costs before scaling.
Yes. It is platform-neutral. Use the expected CPA and economics for the channel you want to evaluate.
Break-even CPA leaves approximately zero modeled profit. A lower target CPA can preserve a desired profit margin and gives you a more useful scaling threshold.
