Enter the power usage (kWh) and the unit cost ($/kWh) into the Calculator. The calculator will evaluate the Ac Cost Per Hour. 

Ac Cost Per Hour Formula



  • ACPH is the Ac Cost Per Hour ($/hr)
  • PU is the power usage (kWh)
  • UC is the unit cost ($/kWh)

To calculate Ac Cost Per Hour, multiply the power usage by the unit cost.

How to Calculate Ac Cost Per Hour?

The following steps outline how to calculate the Ac Cost Per Hour.

  1. First, determine the power usage (kWh). 
  2. Next, determine the unit cost ($/kWh). 
  3. Next, gather the formula from above = ACPH = PU * UC.
  4. Finally, calculate the Ac Cost Per Hour.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.
