How the estimator works
Build the estimate from the project outward.
Renovation budgets are easier to understand when each major part of the project is separated before labor, fees, and contingency are added.
Add labor and fees
Labor can represent a large part of a renovation budget, while permits, design, inspections, and professional fees may add separate costs.
Keep a contingency
Renovation projects can uncover hidden damage, code issues, or scope changes. A reserve helps keep those surprises visible in the plan.
Method: The calculator adds the entered project categories, applies the selected kitchen multiplier, adds the labor allowance and project fees, then calculates contingency on that combined amount. Cost per square foot is the final estimate divided by the renovated square footage entered. This is a planning tool, not a contractor quote.

Common questions
Home renovation cost estimator questions.
Is this a contractor quote?+
No. The tool is designed for early-stage budgeting. Actual costs depend on location, contractor pricing, materials, project complexity, permits, site conditions, and the final scope of work.
Why include a contingency reserve?+
Renovation work can reveal hidden conditions or lead to changes in scope. A contingency reserve keeps some room in the budget for costs that were not obvious at the beginning.
What should I enter for labor?+
Use a percentage that reflects your planning assumption or contractor information. If you receive detailed labor quotes later, replace the allowance with more specific numbers.
Does the estimate include financing costs?+
No. Loan interest, lender fees, home-equity financing costs, and other borrowing expenses are not automatically included.
