Renovation cost guides and calculators
Renovation costs change with scope, finish choices, layout changes, and conditions hidden behind finished surfaces. Define what stays, what moves, and which allowances are included before comparing estimates.
Estimate coverage
Use only the pricing the evidence supports
Kitchen and bathroom pages cite published national cost-guide ranges and distinguish them from the modeled state-adjusted estimate. Basement, flooring, and deck calculators remain unpublished until their scope and source basis are ready. Project ranges are illustrative models, not verified contractor prices. Selected models may use a broad state-level BEA price index when ZIP-to-state mapping succeeds; that is not ZIP-level pricing. Published guide references and homeowner-entered amounts remain separate.
Scope before price
What shapes a useful estimate?
- Room size, finish selections, and the number of trades involved
- Moving plumbing, electrical, walls, or other parts of the existing layout
- Demolition, disposal, permits, temporary protection, and hidden conditions

Common planning questions
Why can renovation estimates differ so much?+
Bids may describe different scopes, allowances, products, and exclusions. Compare written line items and change-order terms rather than only the total.
Are the renovation ranges local prices?+
The page cites a third-party national guide range and separately shows a modeled estimate. The state adjustment is a broad price proxy, not a ZIP-level quote or verified local average.
