About & editorial policy

RenoPlanMaker provides free renovation cost, material and budget calculators for homeowners planning DIY work or discussing a project with a contractor. Tools support imperial and metric measurements where relevant.

Estimates, not quotes

Calculators explain their methods and include examples. Default prices and coverage figures are planning assumptions, not live supplier prices. Replace them with local quotes and manufacturer specifications. Regional taxes, site conditions, permits and hidden repairs can substantially change the final cost.

AI assistance and sources

Some text, images and downloadable content are created with AI assistance. Project images are illustrative and are not evidence of completed construction work. Guides include source references where relevant; consult the original sources and current local rules. We do not claim that every estimate or article has been reviewed by a licensed contractor.

Funding and commercial links

As an Amazon Associate I earn from qualifying purchases. Product links may earn a commission. Their presence is not a safety certification, professional endorsement or a guarantee of the lowest price. Planners and PDF reports are sold separately from the free tools through a secure checkout. Any future display advertising will be labeled.
