Well pump replacement is a job most homeowners do once or twice in a lifetime, usually under time pressure — and pricing between contractors can vary widely with no easy way to sanity-check a bid. WellPumpCost exists to answer one question first: roughly what should this cost, given my well?
Cost is built from three inputs — pump type, well depth, and horsepower — split into a pump-unit cost and a labor cost, plus two optional add-ons (pressure tank, control box). Base ranges are cross-referenced from published 2026 national cost data (Angi, LawnStarter/HomeGuide, Bob Vila, and licensed-contractor cost guides) for pump-unit pricing by horsepower, labor by pump type, and how much each additional 100 feet of depth typically adds in pipe, wire, and labor time. The same numbers power both the calculator and the worked examples on the cost-by-type pages, so they never disagree with each other.
It's not a quote. No calculator has seen your well's casing diameter, your local labor market, or the condition of your existing wiring — all of which move the real number. Use this to walk into a contractor conversation with a realistic range in hand, not to skip getting an actual bid.
We're building a network of local well pump contractors — homeowners who request quotes get connected to pros in their area when one is available, and that referral relationship is how this stays free to use. It never changes the numbers the calculator shows you.
