What one honest test costs to finish

Test budgets usually get argued about per idea. The number that actually decides is the cost of one readable verdict: the contacts a strict test needs, multiplied by what a contact costs you, plus the days it takes to send them. Below the floor you are buying a sample; above it you are buying a decision. The same arithmetic runs in the published CLI (npx marketing-mindset sample), and the volume side has its own planner. Everything is computed in your browser; nothing is sent anywhere.

2. The cost of one verdict

3. How to read that number

The floor is the price, not the budget

A test that stops at 40% of its floor has spent 40% of the money and bought 0% of the answer. Either fund the floor or run a cheaper readable unit: a reply instead of a sale, or a tighter list with a higher base rate.

Money buys tests, volume limits them

Budget divided by the cost of one test is how many tests you can afford. How many can run at once is a different question, and it is answered by contacts a day — two live tests in one arm split the volume and neither reaches its floor.

Cost per conversion is not cost per verdict

The conversion cost comes straight out of the base rate, and it moves whenever the list or the offer changes. The verdict cost is fixed by the design of the test. Judge a channel on the second number, then improve the first.
