How this calculator works
This renovation cost calculator creates a practical budget range for kitchen, bathroom, flooring, painting, and general remodel projects in US-dollar planning, with relevance for English-speaking homeowners in the US, UK, Canada, and Australia.
Formula and assumptions
The model applies a project-type cost per square foot, then adjusts for finish level and region cost tier. It reports low, typical, and high estimates plus a contingency reserve and labor/material split.
FAQ
Does this include permits?
Not directly. Use the contingency or adjust region tier if permits, inspections, or design fees are material.
Why are kitchens and bathrooms higher?
They often include plumbing, electrical, cabinets, fixtures, waterproofing, and tighter labor sequencing.
Should I use whole-home square footage?
Use the area affected by the project. For kitchen and bathroom work, enter the room or remodel footprint.
How much contingency is reasonable?
Many homeowners start around 10% to 20%; older homes or unclear scope may need more.
