Summary
This free home renovation cost calculator estimates a fair price range for kitchen, bathroom, whole-house, basement, addition, and roofing projects. It starts from published national average cost-per-square-foot benchmarks, adjusts for your finish level (basic, mid-range, or high-end) and region (national, high-cost metro, or lower-cost area), then lets you paste in your contractor's quote to see if it falls within the normal range, runs suspiciously low, or looks like a red flag worth questioning before you sign.
Home Renovation Cost Calculator: What You Should Pay
Enter your project type, size, finish level, and region to get a fair price range in seconds, then check your contractor's quote against it before you sign.
What goes into the number
Per-square-foot benchmarks
Each project type starts from a published national average cost per square foot, the same kind of benchmark contractors and estimators use to scope a job.
Finish level multiplier
Basic, mid-range, and high-end finishes scale that base rate to match the real gap between a cosmetic refresh and a full gut renovation.
Regional labor cost
A kitchen in San Francisco or Boston costs meaningfully more than the same kitchen in rural Ohio. Pick the region closest to your ZIP code to adjust for that.
Quote red flag check
Add your contractor's number and the tool flags it as fair, on the low side, or well above the typical range, so you know what to ask before you sign.
