How our calculators work
Each calculator multiplies a national baseline price by 4-5 multipliers (material, size, complexity, project specifics) and a state-level cost index from BLS Regional Price Parity (2022).
The output is a range, not a single number — we never claim to predict your exact contractor quote. Use it to spot quotes that fall materially outside the typical range for your project type and state.
