Generator Cost Estimator & Prices
What a generator really costs — estimate the all-in installed price by kW, fuel and install complexity, and see typical price ranges for whole-house standby and by brand.
gennyguide’s cost tools turn the fuzzy question “how much does a generator cost?” into a real number you can budget with. The cost estimator adds up the equipment, transfer switch, installation labor, fuel hookup and permit for your setup and returns an all-in installed range, broken down so you can see where the money goes. The cost guides put typical price ranges on the common cases — a whole-house generator, the same job installed, and by-brand pricing like Generac — and hand you off to real local quotes. Every figure is a planning estimate; site access, gas and electrical runs and permit fees move the final price, so confirm it with a licensed installer.
