Generator Budget helps U.S. homeowners plan a residential standby-generator project before requesting contractor proposals. The calculator presents itemized low, typical, and high installed-cost ranges rather than a single unexplained number. Homeowners can compare generator size, fuel, location, coverage, and installation-scope assumptions, then review the line items that drive the result. Supporting planning tools cover generator sizing, transfer-switch installation cost, written-quote comparison, scheduled maintenance, outage fuel running cost, financing payment sensitivity, and placement questions. The site explains its boundaries and source-backed assumptions. Results are planning estimates for early comparison, not contractor quotes, electrical designs, code-compliance decisions, tax advice, or an installation recommendation.
