Cost Per Second Formula
The following equation is used to calculate the Cost Per Second.
CPS = TC / S
- Where CPS is the cost per second ($/second)
- TC is the total cost ($)
- S is the total number of seconds
To calculate the cost per second, divide the total cost by the number of seconds.
What is a Cost Per Second?
Definition:
Cost per second refers to the average cost incurred for every second of usage or time. It provides a high-resolution view of expenses and is especially useful for comparing rates or evaluating time-sensitive costs.
How to Calculate Cost Per Second?
Example Problem:
The following example outlines the steps and information needed to calculate the Cost Per Second.
First, determine the total number of seconds. In this example, someone used a service for 3600 seconds (1 hour).
Next, determine the total cost for that period. The service cost $72.00.
Finally, calculate the cost per second using the formula above:
CPS = TC / S
CPS = $72 / 3600
CPS = $.02 / second
FAQ
When should I use cost per second?
Cost per second is most valuable when you need precise cost details for time-bound activities, like measuring short usage intervals or comparing services that charge on a per-second basis.
How does cost per second help with budgeting?
Cost per second gives a granular look at expenses, which can be helpful when deciding how to allocate resources or evaluating whether certain time-based costs are justified.
Is it necessary to measure costs down to the second?
While not always necessary, measuring costs by the second can be beneficial if exact usage times matter for your operations or billing structure. This approach can highlight small but frequent expenses that may go unnoticed with broader time frames.
