When using your credit card, if you keep to under your spending limit your FICO score likes this.
When you then charge so much that you are very close to your credit spending limit, your FICO score will go down.
Why? Read the quote below and see why no matter what you do, it is a "catch 22" situation. But what I leaned is that your FICO score keeps changing so one month it may be better than another due to your spending activities and how you are paying for them.
So one month you charge a good deal and the next month you don't owe too much. Your score will be revised.
If asking for a credit increase is not for you, then try making a partial payment during your billing cycle to then open up your credit availability during that billing cycle's period.
Here is the quote:
- Proportion of balances to crdt limits is too high on bank / revolving accts Hide details
- Consumers who use a high percentage of their available credit (generally known as utilization) have a higher risk of delinquency (falling behind on payments) and charge-off (loan default) over time. Lower use of available credit allows consumers who have the need to temporarily carry higher loan balances to do so, because they have available credit on their accounts. Consumers with heavier credit usage cannot absorb changes to their financial situation as easily, which can lead to higher risk over time. Keeping credit balances lower in relation to available credit will help reduce the negative impact on a credit score over time.
