Short answer: Overall utilization combines selected revolving balances and limits. Per-card utilization performs the same calculation separately for each account.
Overall utilization example
Card A has a $1,000 limit and $900 reported balance. Card B has a $9,000 limit and $100 reported balance. Combined balances are $1,000 and combined limits are $10,000.
Overall utilization is $1,000 ÷ $10,000 × 100 = 10%.
Per-card utilization example
Card A is $900 ÷ $1,000 = 90%. Card B is $100 ÷ $9,000, or about 1.11%.
The 10% overall figure is accurate for the combined inputs, but it does not reveal that one card represents 90% of its own limit.
Why both views are useful
Overall utilization describes the selected revolving accounts together. Per-card utilization reveals concentration on an individual line.
Neither ratio guarantees a particular score or approval result. They are descriptive calculations based on the balances and limits reported or entered.
Avoid mismatched dates
Comparing one card’s current app balance with another card’s older reported balance creates an inconsistent snapshot. Use figures from comparable dates when possible and record the source of each number.
Balances above limits
A balance above its stated credit limit produces a utilization rate above 100%. If that result is unexpected, verify that the balance and limit come from comparable records and dates. The calculator displays the ratio and a warning rather than hiding the condition.
