I'm confused on how and when credit card utilization is calculated for one's credit score. Is the credit card utilization percentage calculated based on the maximum balance you had in a given month? Or the balance at the end of the month? Or some other metric? Here's an example to illustrate my question:
Say you have a credit card with a limit of $2,000. Every month you have a bill for $200 that you charge to this card. But you pay it off within hours or minutes of it being charged. So for the majority of the time, and at the end of the month, you have a balance of $0.
Will your utilization percentage be 10%, because the maximum you had at one point was $200 / $2,000 = 10%? Or would it be 0% if your score is calculated after you have paid it off? Is there a certain time (e.g. the last day of the month) that your balance is checked, and your utilization percentage is calculated?
