Energy variance calculator

Subtract predicted energy from actual use; a positive result means consumption exceeded the modeled baseline.

Variance=Actual energy−Predicted energy\text{Variance} = \text{Actual energy} - \text{Predicted energy}

Worked example

Given

  • Actual energy\text{Actual energy} = 98,200 energy unit
  • Predicted energy\text{Predicted energy} = 94,000 energy unit
Variance=98,200−94,000=4,200\text{Variance} = 98{,}200 - 94{,}000 = 4{,}200
