Free Tools

Remodeling cost calculators.

Check a contractor's bid, build a true-cost estimate from scratch, or size a job with a trade-specific calculator. Every tool runs on the same independent index: BLS wages, Craftsman labor hours, current material prices, and the verified permit fee in your city. No lead forms, no signup.

How The Tools Work

Real math, not estimates.

Every number traces to the same sources: federal BLS wages for your metro, Craftsman labor hours for the task, current material prices, and the actual permit fee in your city. That sum is the cost to deliver, the break-even, not your target price. What a contractor keeps on top is margin, and a fair one is earned. The tools show you the line so you can see both halves.
