Switching from traditional gas or electric furnaces to a heat pump can significantly reduce your energy bills. Use our heat pump savings calculator to estimate your potential annual savings based on efficiency ratings and local utility rates.
Heat Pump Savings Calculator
Heat Pump Savings Calculator Formula
Source: U.S. Department of Energy – Heat Pump Systems
Variables Explanation:
- Current Cost: The total amount you spend annually on your current heating fuel (Gas, Oil, or Electric).
- Electricity Rate: Your local utility cost per kilowatt-hour ($/kWh).
- Heat Pump COP: Coefficient of Performance. A COP of 3 means the unit produces 3 units of heat for every 1 unit of electricity.
- Annual Heating Load: The total energy required to heat your home for a year, measured in kWh.
What is Heat Pump Savings Calculator?
The heat pump savings calculator is a financial tool designed to help homeowners evaluate the ROI of upgrading their HVAC systems. Unlike traditional resistive heaters or furnaces that generate heat, heat pumps move heat, making them up to 400% efficient.
This tool accounts for the variable efficiency of modern air-source or ground-source heat pumps, allowing you to compare your current fuel expenditure against the projected operational costs of a high-efficiency electric system.
How to Calculate Heat Pump Savings (Example)
- Determine your current heating load (e.g., 20,000 kWh per year).
- Check your electricity rate (e.g., $0.12/kWh).
- Identify your proposed heat pump’s average COP (e.g., 3.0).
- Calculate operational cost: $(20,000 / 3.0) \times 0.12 = \$800$.
- Subtract this from your current bill (e.g., $2,000 – $800 = $1,200 savings).

Frequently Asked Questions (FAQ)
Is a heat pump cheaper than gas? This depends on local utility prices. If electricity is cheap and natural gas is expensive, heat pumps offer massive savings.
What is a good COP for a heat pump? Most modern units have a COP between 2.5 and 4.0. Higher ratings mean lower operating costs.
Do heat pumps work in freezing temperatures? Yes, modern “Cold Climate” heat pumps can operate efficiently even at -15°F (-26°C).
How long does it take for a heat pump to pay for itself? Depending on rebates and savings, most homeowners see a break-even point within 5 to 10 years.
