What the result means
The result shows whether energy is a material household expense and how much could be saved by efficiency upgrades or usage reductions.
Total energy cost = electricity + gas + heating and cooling. Potential savings = total energy cost × target reduction percentage.
This calculator is an estimate for planning. Review actual bills, local prices, and household agreements before making major financial decisions.
Example calculation
Electricity $120, gas $70, and heating/cooling $160 create a $350 monthly energy cost. A 12% reduction saves $42 per month.
Tips for better results
- Improve insulation before replacing systems.
- Track seasonal peaks separately.
- Use the target reduction to test realistic changes.
