Energy cost comparison evaluates the annual running costs of different heating, cooling, and energy systems to identify the most cost-effective option. Annual Savings = Current Annual Energy Bill − Alternative Annual Cost. Annual bill per household typically target Below $1,800.

What is Energy Cost Comparison?
Energy cost comparison evaluates the annual running costs of different heating, cooling, and energy systems to identify the most cost-effective option. This includes comparing gas furnace vs heat pump, the impact of insulation improvements, and solar vs grid electricity. For solar-specific analysis, see the Solar Savings Calculator.
The Formula
Annual Savings = Current Annual Energy Bill − Alternative Annual Cost
Worked Example
A household currently spends $2,640/year on gas heating ($220/month). They're considering an air source heat pump that would cost $1,320/year to run, plus insulation improvements that reduce both options by 15%.
- Current cost after insulation = $2,640 × 0.85 = $2,244
- Heat pump cost after insulation = $1,320 × 0.85 = $1,122
- Annual savings = $2,244 − $1,122 = $1,122
📌 Switching to a heat pump with insulation saves $1,122/year — the heat pump installation cost of $12,000-25,000 (before 30% ITC) pays back in 7-15 years after the federal tax credit.
Why This Matters
Rising energy costs
US electricity prices have risen 15-20% since 2021 (EIA data). Comparing alternatives now protects against future price rises and identifies the most resilient long-term strategy for your home.
Federal incentives
The 30% Federal ITC covers heat pumps under the Inflation Reduction Act, and the 25C credit provides up to $2,000 for qualifying HVAC equipment. Factor these incentives into your comparison for the true net cost.
Common Mistakes
❌ Comparing running costs only
A heat pump may save $1,000/year in running costs but requires $15,000 upfront installation (before ITC). Include capital costs and calculate payback period for a fair comparison — don't just compare monthly bills.
❌ Ignoring property suitability
Heat pumps work best in well-insulated homes with properly sized ductwork. Installing one in a poorly insulated older home without upgrades will deliver higher running costs than promised and may require a supplemental heating source in cold climates.
