How to use this tool

1
Enter card 1

Type balance and credit limit.

2
Enter card 2

Add a second card; enter $0 balance for one card only.

3
Add a planned purchase

In Advanced options, see utilization after a new purchase.

4
Check per-card figures

One maxed card matters even if the total looks fine.

Formula & worked example

Utilization = total balances / total credit limits x 100. Per-card utilization = that card's balance / its limit x 100. Projected utilization adds a planned purchase to balances before dividing.

Worked example: Card 1 $2,000 / $5,000 = 40%. Card 2 $1,000 / $5,000 = 20%. Overall ($2,000 + $1,000) / ($5,000 + $5,000) = $3,000 / $10,000 = 30%.

Limitations — read this before you rely on it

Utilization is one scoring factor among many, and scoring models and reporting dates differ. Balances are usually reported monthly, so paying before the statement date can change the reported figure. This is not credit advice.
