Renovating or considering a home improvement project? See how much it could cost, based on what other homeowners paid across the nation.

The calculator includes national data. Keep in mind that these are average national values, so your home renovation could cost more or less.

Costs tend to vary based on local market conditions, how elaborate the renovation is (for example, a renovation with the most expensive materials could skew much higher, whereas using low-cost supplies could cause the renovation to be cheaper), and how extensive it is (such as a complete renovation versus a partial one).

We recommend using the data above as an initial indication of the cost of a renovation, but homeowners are likely to get the best deal by comparing multiple quotes from contractors. You can also check sites like Angi for additional data.
