Adjust local pricing assumptions

These are editable planning assumptions—not contractor quotes. Local pricing can differ significantly.

FREE BID COMPARISON WORKSHEET

Compare contractor quotes on the same scope

Enter up to three written bids line by line. The worksheet totals priced items, highlights missing scope and gives you questions to ask before signing. Your entries stay in your browser.

Compare contractor bids

Why bid totals can mislead

A lower bid may leave out permits, disposal, finishes or work another contractor includes. Mark unclear items as unknown, then request comparable written proposals.

What ProjectCostWise is — and isn’t

ProjectCostWise provides educational planning estimates based on the assumptions you enter. It does not inspect your property, provide a binding quote, or replace a licensed professional where one is required.

Why homeowners use it

A planning range can help you spot unrealistic expectations, compare bids more consistently, and ask better questions before signing a contract.
