How to Improve Your Credit Score

  1. Pay every bill on time, every time. Set up direct debits for at least the minimum payment.
  2. Keep credit card balances low. Aim to use less than 30% of your credit limit. Read our full guide on building credit from scratch if you're just starting out.
  3. Don't close old accounts. Even if you don't use a card, keeping it open preserves your credit history length.
  4. Avoid applying for multiple credit products at once. Each hard inquiry slightly lowers your score.
  5. Check your credit report for errors. Mistakes are surprisingly common — dispute anything that looks wrong.

Why Does Your Credit Score Matter?

A good credit score can save you thousands of dollars over your lifetime. On a 30-year mortgage, someone with an excellent score might pay a full percentage point less in interest than someone with a fair score — that's potentially $50,000+ in savings.

  • The deposit required for utilities

  • Job applications in certain industries

Cómo mejorar tu puntaje de crédito

  1. Paga todas tus obligaciones a tiempo, siempre. Configura débitos automáticos para al menos el pago mínimo.
  2. Mantén bajos los saldos de tus tarjetas. Usa menos del 30% de tu cupo disponible.
  3. No cierres cuentas antiguas. Aunque no uses una tarjeta, mantenerla abierta preserva tu antigüedad crediticia.
  4. Evita solicitar múltiples créditos al mismo tiempo. Cada consulta a tu historial puede bajar tu puntaje levemente.
  5. Revisa tu reporte de crédito. Los errores son más comunes de lo que crees — impugna cualquier dato incorrecto ante la central de riesgo.

¿Por qué importa tu puntaje de crédito?

Un buen puntaje puede ahorrarte millones de pesos a lo largo de tu vida. En un crédito hipotecario a largo plazo, alguien con un puntaje excelente puede pagar un punto porcentual menos de interés que alguien con puntaje regular.
