Renovation budget spreadsheets by room and project type

A basement finish, a deck and a whole-house renovation share the same money questions: what you budgeted, what you agreed to pay, what you paid and what is left in the contingency. Pick your project for a worked example.

General information only, not financial, construction or legal advice. Contingency, holdback and payment-split percentages are your own inputs, and payment and deposit rules vary by contract and by state or province; check yours. Names and numbers in the example are invented.
