Electricity cost savings calculator

Multiply avoided kWh by the applicable energy rate; demand is a separate calculation.

Se=ΔE×ceS_{e} = \Delta E \times c_{e}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Worked example

Given

  • ΔE\Delta E = 28,000 kWh/yr
  • cec_{e} = 0.14 $/kWh
Se=28,000×0.14=3,920S_{e} = 28{,}000 \times 0.14 = 3{,}920
