FREE TOOL: NO SIGNUPWhat your ad budget actually buys, in your numbers
An ad account will happily spend $30 a day forever without ever showing you the only chain that matters: spend → clicks → leads → customers → profit. Enter your five numbers and see the whole chain, including the maximum click price your economics can afford.

Break-even CPC = conversion rate × close rate × job value × gross margin. Above it, every click loses money on the first job.
Most losing ad accounts fail at one link, not all five.
A high CPC, a landing page that doesn't convert, or leads that never get answered are three different problems with three different fixes, and buying more budget fixes none of them. A marketing audit finds which link is broken using your real account data, with published pricing and no discovery call. If leads go unanswered, the missed-call calculator prices that leak.
See the marketing services- Does anything I type get sent anywhere?
- No. The arithmetic runs in your browser as JavaScript on this page. There is no account, no upload and no server call.
- Where should my inputs come from?
- Your ad account and your books, not industry averages. CPC and click volume are in Google Ads or Meta Ads Manager; conversion rate needs your form/call tracking; close rate and job value come from your own sales records. This calculator multiplies five numbers: a guessed input produces a confidently wrong output.
- Why does it ask for gross margin?
- Because revenue-based ROAS flatters everyone. A 3x ROAS on 30% margins loses money once you pay for the work. The profit line here is margin on ad-driven revenue minus the ad spend, the number your bank account experiences.
- What is the "maximum affordable CPC"?
- The break-even click price for your funnel: conversion rate × close rate × job value × gross margin. Pay more per click than that and every click loses money on the first job. It is the single most useful number to bring to an ad account review.
- My ads "work" but this says they lose money. Who is right?
- Check whether repeat business belongs in job value. If a new customer is worth several jobs over time, use first-year value instead of one ticket, the LTV vs CAC calculator on this site does exactly that. If it still loses money on first-year value, the calculator is right and the ad account needs work, not more budget.
