Credit Utilization Calculator
The share of your credit limits you are using — a heavyweight in credit scoring. Enter total balances and limits, and see the pay-down needed to reach 30%, 10%, or your own target.
The ratio your score watches daily
Utilization — balances divided by limits, per card and overall — is one of the heaviest levers in credit scoring. It has no memory of last month's virtue in most scoring models: the balance reported this cycle is the fact. That quirk makes utilization the fastest score lever a borrower fully controls.
Utilization = total balances ÷ total limits × 100
Example: $4,200 across cards with $12,000 of limits: utilization 35%. Paying $600 brings it to the classic under-30% zone at $3,600; reaching the under-10% zone that top scores favor takes the balance to $1,200 — a $3,000 pay-down, which the result itemizes for your own target.
The statement-date trick
Issuers typically report the statement-closing balance. A payment that lands before the statement closes — not merely before the due date — lowers the reported balance and thus the utilization the bureaus score. It costs nothing but calendar awareness.
How this is calculated
Straight ratio on your totals, plus the pay-down arithmetic for your target: max(0, balances − limits × target%). The page works on aggregates; scoring also weighs your highest single-card utilization, so a balanced total with one maxed card is worse than it prints here — the text says so rather than pretending otherwise.
Frequently asked questions
Is under 30% really the threshold?
It is a rule of thumb, not a cliff: scoring treats utilization as a gradient, with the best outcomes typically under 10% and damage growing steeply past 30–50%. Lower is better; zero on every card can actually score slightly worse than a token balance somewhere.
Does utilization have a memory?
In the widely used FICO 8, no — it reads the current reported balances. Newer models (FICO 10T, VantageScore trends) look at trajectories, which rewards sustained pay-down rather than one heroic month.
Will a limit increase help?
Mechanically yes — the denominator rises. It helps exactly insofar as the balance does not follow it up, which is a statement about the holder, not the math.
Do charge cards and business cards count?
Traditional charge cards without preset limits have been treated inconsistently across models; most business cards do not report to personal bureaus at all. This page covers the standard personal revolving picture.
