The 24-Hour Guarantee

Free tools

The numbers, before you need us.

Calculators for the questions contractors actually get stuck on: what an hour really costs, what to charge for a call, whether that job made money, what the truck costs, and whether you can afford another tech. No email box, no results to unlock, nothing sent anywhere.

The 24-Hour Guarantee— Your first month back in 24 hours, or the next month is free.

Every one of these runs in your browser. Nothing you type is sent to us, there is no email box, and the answer is never hidden behind a form. If a calculator on another site makes you hand over your address to see your own arithmetic, that is a lead magnet wearing a calculator’s clothes.

These run on numbers you guessed. We can run them on the real ones.

Every calculator here needs figures most owners have never had in front of them — true burden, actual overhead, real callback cost. A month of properly kept books produces all of them. We do your most recent month in full, free, delivered in 24 hours and signed by a US CPA.
