How the Factors Combine

You've now met all five main factors: payment history, credit utilization, length of credit history, credit mix, and new credit inquiries. No two scoring models weigh them identically, and exact formulas are generally proprietary, but most models share a rough pattern in how much attention each factor gets.

This next breakdown is illustrative only, meant to show the general order of importance rather than an official universal formula. Treat the numbers as rough proportions, not a precise recipe any specific scoring model actually uses.

Roughly how the factors are generally weighted (illustrative, not official):

  Payment history            ~35%   biggest single factor
  Credit utilization         ~30%   second biggest
  Length of credit history   ~15%
  Credit mix                 ~10%
  New credit inquiries       ~10%

Across most scoring models, payment history and credit ____ together generally make up the largest share of a score.

What's the right way to treat the illustrative percentage breakdown of credit score factors?

Every credit scoring model in existence uses the exact same published percentage for each factor.

Put together, the factors split into two groups: things you can influence relatively quickly, like utilization, and things that only shift slowly, like length of credit history. Focusing energy on paying on time and keeping utilization low covers the two biggest levers, while the rest mostly takes care of itself with patience.
