Planning a remodel and need a real number before you start calling contractors? Our free renovation cost calculator gives you an instant ballpark for six common projects — bathroom remodels, kitchen remodels, basement finishing, roof replacement, interior painting, and flooring — using the same 2026 national cost data published in our detailed guides.
Pick your project, choose a finish level, and enter your size. You’ll get an estimated cost range plus the per-square-foot rate behind it, so you can sanity-check any quote you receive. No email, no sign-up — just a fast, honest starting number for your home renovation budget.
Estimates only, based on 2026 national averages from our guides; actual costs vary by city, materials and contractor.

Skip the dropdowns: describe your project in your own words and we’ll work out the numbers. Prices always come from the same 2026 cost data published in our guides — the AI only reads your description, it never makes up prices.
Every rate in this calculator comes from the 2026 cost data in our own published guides — the same figures contractors’ bids are checked against in those articles. That makes it a solid planning number, not a quote. Your real price will move with local labor (high-cost coastal metros typically run 20–50% above the national baseline, while smaller cities land near or below it), the exact materials you choose, and surprises hidden behind walls. Treat the range as your starting point, hold a 10–20% contingency, and always get at least three itemized quotes before you sign.

It depends on the project. Our guides put 2026 bathroom remodels at $3,000–$50,000+, kitchen remodels at $8,000–$150,000+ depending on size and scope, and basement finishing at $30–$75 per square foot. Use the calculator above for a ballpark for your project, then read the linked guide for the full breakdown.
It is a planning tool, not a quote. Every rate comes from the 2026 cost data published in our own guides, but your final price will move with local labor rates (high-cost coastal metros run 20–50% above the national baseline), material choices, and what the crew finds behind your walls. Always compare at least three itemized quotes before signing a contract.
Scope and layout changes. In kitchens and bathrooms, moving plumbing, walls, or drains is what jumps a project into the next budget tier — keeping the same footprint is the single biggest money saver. After that: finish level (materials), project size, and your region’s labor rates.
Yes. Our guides recommend holding a 10–20% contingency on top of any quote, especially in bathrooms and basements where rot, mold, and outdated wiring hide behind finishes. If the project finishes clean, you simply keep the money.
