Generator cost FAQs

The SEO content engine — each answer targets a search query that buyers type.

How much does a whole-house generator cost installed in 2026?

Most homeowners pay $6,000–$11,000 for a fully installed and permitted standby system, and $9,500–$24,000 for large homes or complex sites. The unit itself is typically $3,000–$6,000, with installation labor adding $3,000–$5,000+.

What size generator do I need for my house?

Essentials-only coverage runs on 10 kW; a typical 2,000 sq ft home needs 14–18 kW; whole-home coverage for 2,500–3,500 sq ft usually means 22–26 kW. Our calculator maps this automatically from what you want powered.

Is a standby generator worth the money?

In outage-prone areas, standby generators consistently return value: they protect against spoiled food, frozen pipes, sump-pump failure and lost remote-work days — and real-estate studies suggest they can add ~3–5% to resale value.

Natural gas vs propane generator — which is cheaper?

If you already have utility natural gas, it's usually the cheapest to run and install. Propane costs more per kWh and may require a tank ($500–$1,800), but works anywhere and stores indefinitely.
