Enter the total cost ($) and the total number of bits into the Calculator. The calculator will evaluate the Cost Per Bit. 

Cost Per Bit Formula

CPB = C / B


  • CPB is the Cost Per Bit ($/bit)
  • C is the total cost ($)
  • B is the total number of bits

To calculate the Cost Per Bit, divide the total cost by the number of bits.

How to Calculate Cost Per Bit?

The following steps outline how to calculate the Cost Per Bit.

  1. First, determine the total cost ($). 
  2. Next, determine the total number of bits. 
  3. Next, gather the formula from above = CPB = C / B.
  4. Finally, calculate the Cost Per Bit.
  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.

total cost ($) = 7789

total number of bits = 200
