Questions homeowners ask

Are these calculators free to use?
Yes. Every calculator on CostToUpgrade is free, requires no sign-up, and runs entirely in your browser.
How accurate are the estimates?
Our formulas use standard construction rules of thumb and the prices you enter, so the math is exact for your inputs. Real-world cost still depends on local labor, site conditions, and supplier pricing, so treat results as a budgeting starting point and confirm with a local pro.
Do you store the numbers I enter?
No. Calculations happen on your device. We do not send your project inputs to a server or save them.
Can I use these estimates to get contractor quotes?
Absolutely — that is exactly what they are for. Bring your material quantities and a target budget to contractors so you can compare their quotes on equal footing.
