How much does a home renovation cost per square foot?

A light refresh can be much lower than a full gut renovation. Use the scope selector and local market adjustment for an early budget range, then compare contractor bids.

Should I add a contingency?

Yes. A 10-20% contingency is common for hidden conditions, scope changes and price movement. The calculator defaults to 15%.

Is this a contractor quote?

No. It is a planning estimate. Final pricing depends on local labor, permits, material choices, demolition, access and a detailed scope of work.

Estimate renovation cost per square foot

English remodel-cost searches usually expect a fast budget range: square footage, project scope, local cost market and a contingency. The calculator uses U.S.-style dollars per square foot and splits the result into materials, labor and buffer.

C os t = A_{f t^{2}} \times R a t e_{f t^{2}} \times M a r k e t

Aft2 is project area and Rateft2 is the selected remodel scope rate.

T o t a l = C os t \times (1 + C o n t in g e n cy)

The default workflow uses a contingency so the estimate is not a bare minimum.

What can change the final bid

Kitchen, bathroom, structural, plumbing and electrical work can move a project far above a simple finish refresh.
Permit rules, contractor availability, access, demolition, debris hauling and material grade change the final contract price.
Square-foot estimates are useful for early planning, but a contractor bid needs a room-by-room scope and specifications.
