Heat Pump Payback Calculator | The Greener Electron

See how quickly a heat pump could pay for itself. Enter your numbers below and the calculator estimates your annual savings, payback period, and long term net savings. Every assumption is visible and editable, because honest math beats marketing math.

Your current heating

Current heating system Used to estimate your system’s efficiency. You can override the efficiency in the assumptions below. Annual heating cost ($) Your total yearly spend on heating fuel or electricity for heat. Check past utility bills for your best estimate.

The heat pump option

Installed cost ($) Full quote from an installer, before incentives. Typical range: $8,000 to $20,000 depending on home size and system type. Heat pump efficiency (seasonal COP) A COP of 3.0 means the system delivers 3 units of heat for each unit of electricity. Cold climate models typically rate 2.5 to 3.5 for the season. Electricity price ($ per kWh) Find this on your electric bill. US average is around $0.17 per kWh. Incentives and rebates ($) Federal tax credits, state rebates, and utility incentives you expect to receive. Verify current programs in your area.

Assumptions (tap to view and edit)

System lifetime (years) Annual heat pump maintenance ($) Yearly service cost. Upkeep of your current system is assumed similar and excluded from both sides. Annual energy price increase (%) Applied equally to your current fuel and to electricity. Current system efficiency (%) Auto set from your system type above. Override it here if you know your equipment’s rated efficiency.

Fuel energy content used in the math: natural gas $1.50 per therm, heating oil $3.80 per gallon, propane $2.80 per gallon. These are typical US figures. If your local prices differ a lot, adjust your annual heating cost input so the totals stay realistic.

Before you decide

This is an estimate, not a quote. Real efficiency depends on your climate, insulation, ductwork, and installation quality.
Cooling savings are not included. A heat pump also replaces your air conditioner, which can add meaningful summer savings.
Get at least three installer quotes. Installed cost is the biggest variable in the payback math, and quotes vary widely.
Verify incentives yourself. Federal, state, and utility programs change often and have fine print on equipment requirements.
Cold climates need cold climate equipment. If winter temperatures regularly drop below freezing where you live, look for models rated for low ambient operation and use a conservative COP above.
