Credit utilization ratio is the share of revolving credit you are using: balance divided by credit limit. Scoring models (FICO and VantageScore variants) treat utilization as a major part of “amounts owed.” A “good target” in consumer education is often under about 30%, with many score-focused borrowers aiming under 10%. Those bands are heuristics, not a published FICO cliff at 29.9%.
This page is the definition + target math. Broader myths and reporting timing: Credit utilization. Mid-cycle paydown tactics: Lower utilization without paying the statement balance.
The ratio in one line
Utilization = revolving balance ÷ revolving credit limit
Calculate it two ways:
| View | Formula | Why it matters |
|---|---|---|
| Per card | That card’s balance ÷ that card’s limit | One maxed card can hurt even if others are empty |
| Overall | Sum of revolving balances ÷ sum of revolving limits | Snapshot of total revolving pressure |
Installment loans (auto, mortgage, student) are not part of classic revolving utilization. They matter elsewhere in the score.
Worked math
| Card | Balance | Limit | Per-card utilization |
|---|---|---|---|
| Card A | $900 | $1,000 | 90% |
| Card B | $100 | $4,000 | 2.5% |
| Overall | $1,000 | $5,000 | 20% |
Overall 20% looks “fine” under a 30% rule of thumb, but Card A at 90% is still a problem line. Targets should include both views.
What counts as a good target?
| Target band | How people use it | Caveats |
|---|---|---|
| Under 30% overall | Common educator/CFPB-facing shorthand | Not a law; big jumps down from 80% help more than polishing 28% → 22% |
| Under 10% overall | Common “score optimizer” band before a mortgage pull | Still pay on time; 0% on every card is not required |
| Under 30% per card | Avoids a single maxed tradeline | Ask for a limit increase only if you will not spend the headroom |
| Near 0% reported | Some people pay before statement close | A small reported balance with on-time history is normal |
Payment history still outweighs utilization. A clean 22% file beats an 8% file with a fresh 90-day late.
How to move toward the target
- Pay before the statement closing date so a lower balance reports (not only before the due date).
- Split charges across cards only if each stays in a sane per-card band.
- Request a limit increase (ask soft vs hard first) rather than closing a high-limit card you behave with (When closing hurts).
- Expect temporary spikes after travel or a large purchase; plan a same-cycle paydown (Utilization spike after a large purchase).
Worked example: picking a target before a car loan
Sam’s overall utilization is 42% ($6,300 / $15,000). Sam wants under 30% within one billing cycle.
| Action | New balances / limits | New overall |
|---|---|---|
| Pay $2,000 extra before statement close | $4,300 / $15,000 | 28.7% |
| Same paydown + $3,000 limit increase on one card (if approved) | $4,300 / $18,000 | 23.9% |
Sam picks the paydown first (no inquiry risk). Limit increase is optional week two after confirming soft vs hard pull.
Checklist
- List every revolving balance and limit from your latest statements or reports.
- Compute overall and worst per-card ratios.
- Choose an upper target (under 30% as a rule of thumb; under 10% before a score-sensitive application).
- Schedule a pre-statement payment large enough to hit the band.
- Re-check after the bureaus update (often one statement cycle), not the next morning.
