Working tools, left on the counter.

A word on why these are free. Every agency says “we understand contractors”; few can prove it before the invoice. These calculators are the proof. The math runs right in your browser — no login, no card, no salesman calling Tuesday, and no limit on how often you run it. Together they answer the two questions every shop should be able to answer cold: what the phone is leaking, and what a booked job truly costs. If either number surprises you, you will know exactly what kind of work this shop does, and where to find it when the big job comes up.
