How to use this calculator

Enter electricity, gas, heating/cooling cost, and your target reduction percentage. The calculator estimates monthly cost, possible savings, and annual energy spend.

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.
