About this tool
It multiplies area by cost per square foot, then adds a contingency percentage on top, because renovation surprises are common and a budget without slack rarely survives contact with an old house. All figures here are estimates: check current rules and rates before acting on them.
Frequently asked questions
Are these figures exact?

What should I do with this estimate?
Use it to compare options and plan your next step, then confirm the final figure with the provider, lender, or adviser involved before committing money.
