Common Questions
How much does a whole-house generator cost?
Most whole-house generators cost $8,000–$25,000 installed, depending on size and location. A typical 22kW unit runs $12,000–$18,000 including installation. Our calculator gives you a personalized estimate.
What size generator do I need?
It depends on what you want to power. Essential circuits (fridge, lights, outlets) typically need 10–15kW. Whole-home coverage including central AC usually requires 20–25kW or more.
Is this calculator really free?
Yes, completely free for homeowners. We're supported by installers who pay for leads—but only when you choose to connect with them. No obligation.
Who are you?
We're an independent resource helping homeowners make informed decisions about backup power. We're not affiliated with any generator manufacturer—we compare all major brands.
Is this for portable generators?
No. We focus exclusively on whole-house standby generators—permanently installed units that automatically power your home during outages. If you need a portable generator for camping or occasional use, this site isn't for you.
