Heat Pump Cooling Electricity Cost Calculator
Start with a transparent reference model, then change the equipment rating, efficiency, cycling, runtime, state, or cents-per-kWh price to match your situation.
Adjustable HVAC model
Calculate heat pump cooling cost
Annualized at the same daily pattern: $969.21. This is an operating-cost model, not a home load calculation. Weather, thermostat settings, equipment sizing, maintenance, part-load behavior and backup heat can materially change actual consumption.
Efficiency source
EER2 model
Heat-pump efficiency changes with outdoor conditions and part-load operation. EER2 is useful for a transparent rating-point comparison; actual seasonal consumption can differ.
What the estimate excludes
Weather and building load matter
The calculator does not infer insulation, infiltration, floor area, duct losses, local design temperature, thermostat behavior, maintenance condition, or utility fixed charges. Use it to compare operating assumptions rather than to size equipment.
State electricity-price effect
Same HVAC model, different state rate
Formula used
Approximate active electrical input equals cooling capacity in Btu/h divided by EER2. Average modeled input then applies the active/cycling percentage before converting runtime into kWh and cost.
For all modes, electricity cost equals kWh × electricity price in dollars per kWh. Replace the state average with the actual rate from your bill when possible.
