Water Heater Replacement Cost Calculator

Start from a heater at its published Home Depot price, then add the labor, permit and parts lines from your installer's quote. The total is your own arithmetic, shown line by line, so you can check one quote against another.

Your Replacement

Prices listed on homedepot.com, checked 21 October 2026. If your quote names a different heater, type its price below.
Home Depot says a basic like-for-like install typically takes two to three hours. A fuel change, new venting or a tankless conversion takes longer: use the hours on your quote. For scale, the median plumber wage is $30.67 an hour (BLS, May 2025); a company's billed rate is higher.
Permit fees are set by your city or county building department. Expansion tanks, drain pans, venting or electrical changes go in Other.

Nothing here is a typical or average price: the total is your own arithmetic over the heater price and the labor, permit and parts lines on your quote. Ask every installer to itemise those lines so you can compare them here.

How This Calculator Works

Heater prices are the listed prices on homedepot.com for Rheem tank, tankless and heat pump models, checked 21 October 2026 (some from Home Depot's installation page, checked 17 October 2026). Prices change and vary by store. The default of three hours is the top of the two to three hours Home Depot gives for a basic like-for-like installation. No labor rate, permit fee or regional adjustment is assumed: plumbing companies and building departments set those locally, and no public source publishes a national figure for them. The median plumber wage from the Bureau of Labor Statistics (May 2025) is shown for scale only, because a company's billed rate covers overhead and margin on top of wages.

Get at least three itemised quotes from licensed plumbers and run each one through the calculator.

Everything on this site is a general cost reference, not plumbing or gas advice. A leaking tank, a T and P relief valve that is weeping, or any work on a gas connection needs a licensed plumber on site, not an email.
