Before you spend anything on efficiency, it helps to know whether your bill is ordinary or bloated — and this screen answers exactly that. Typical US homes use roughly $1.00-$1.50 per square foot per year in total energy, which gives a simple benchmark of about $0.10 per square foot per month. Enter your average bill and home size and the calculator shows how you compare, then reads your window quality and insulation to estimate what an independent audit would realistically find — usually 10-30% in homes that have never been checked, with the big-ticket items being air sealing, attic insulation and heating and cooling efficiency. You get the potential monthly and yearly savings so the decision to book an audit (many utilities offer one free) is based on a number, not a guess.
Compare your energy bill with a typical bill for a home your size and estimate the realistic savings from the fixes an audit would find — drafty windows, weak insulation and old systems.
A rough national benchmark is about $0.10 per square foot per month — so a 2,000-square-foot home typically runs near $200 a month averaged across the year, with climate and local rates moving it either way. The calculator compares your bill against exactly that benchmark for your size.
Independent audits routinely identify 10-30% savings in homes that have never been checked. The biggest items, in rough order, are air sealing, attic insulation and heating-and-cooling efficiency — followed by the cheap wins like filters, sealing gaps and thermostat scheduling that pay back within months.
Usually not — windows are typically the slowest payback of all the efficiency upgrades. The money-smart order is sealing and insulation first, then system tune-ups, then windows if the budget stretches. An audit measures the actual losses rather than guessing at them.
