How This Calculator Works
Credit utilization is your total revolving credit balances divided by your total credit
limits, expressed as a percentage — one of the most heavily-weighted factors in most consumer
credit scoring models. Enter your total balances and total credit limits across all your
revolving accounts, and this calculator shows your utilization ratio and where it falls against
commonly-cited credit-score guidance.
Unlike payment history, which only reflects past behavior, utilization can change the moment a
balance is paid down — making it one of the faster levers available for someone looking to
improve their credit standing.
The result is then compared against commonly-cited guidance bands:
Utilization
Category
Under 10%
Excellent
10% to 29%
Good
30% to 49%
Fair
50% or above
High
Worked Example
$2,000 in total balances across $10,000 in total credit limits:
Credit Utilization=2,000÷10,000×100=20%.
20% falls in the Good category, comfortably under the commonly-cited 30% guideline.
Cómo funciona esta calculadora
La utilización de crédito es el total de tus saldos de crédito rotativo dividido entre el total
de tus límites de crédito, expresado como un porcentaje — uno de los factores con mayor peso en la
mayoría de los modelos de puntuación crediticia al consumidor. Ingresa el total de tus saldos y
el total de tus límites de crédito en todas tus cuentas rotativas, y esta calculadora muestra tu
razón de utilización y en qué punto se encuentra respecto a las pautas de puntuación crediticia
comúnmente citadas.
A diferencia del historial de pagos, que solo refleja el comportamiento pasado, la utilización
puede cambiar en el momento en que se paga un saldo — lo que la convierte en una de las palancas
más rápidas disponibles para alguien que busca mejorar su posición crediticia.
La fórmula
Utilizacioˊn de creˊdito=Lıˊmites de creˊdito totalesSaldos totales×100
El resultado se compara luego con bandas de referencia comúnmente citadas:

Categoría
Menos de 10%
Excelente
10% a 29%
Buena
30% a 49%
Regular

Alta
Ejemplo resuelto
$2,000 en saldos totales sobre $10,000 en límites de crédito totales:
Utilizacioˊn de creˊdito=2,000÷10,000×100=20%.
El 20% cae en la categoría Buena, cómodamente por debajo de la pauta comúnmente citada del
30%.
Credit utilization is your total revolving credit balances (mainly credit cards) divided by your total credit limits, expressed as a percentage. It's one of the most heavily-weighted factors in most consumer credit scoring models, second only to payment history.
What is a good credit utilization ratio?
A commonly-cited guideline is keeping overall utilization under 30%, with under 10% often cited as ideal for the best scores. Lower is generally better, though 0% (no balances reported at all) isn't necessarily optimal either in every scoring model — check your specific card issuer or scoring model's own guidance for details.
Does this look at each card separately or all cards combined?
This calculates overall utilization across all cards combined. Most scoring models also look at PER-CARD utilization — maxing out one card while others sit empty can still hurt your score even if the combined ratio looks fine, so it's worth checking individual cards too, not just the total.
