Enter the total battery size (kWh) and the cost per unit of power ($/kWh) into the Calculator. The calculator will evaluate the Battery Cost. 

Battery Cost Formula



  • BATC is the Battery Cost ($)
  • BS is the total battery size (kWh)
  • CPE is the cost per unit of power ($/kWh)

To calculate the Battery Cost, multiply the total battery size by the cost per unit of power.

How to Calculate Battery Cost?

The following steps outline how to calculate the Battery Cost.

  • First, determine the total battery size (kWh). 
  • Next, determine the cost per unit of power ($/kWh). 
  • Next, gather the formula from above = BATC = BS * CPE.
  • Finally, calculate the Battery Cost.
  • 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.

total battery size (kWh) = 87

cost per unit of power ($/kWh) = 38
