What is Credit Scoring?
Credit scoring is a method lenders use to assess how likely you are to repay borrowed money on time. Your credit score, ranging from 300 to 850, reflects your payment history, debt levels, and credit behavior. Understanding credit scoring helps you qualify for better loan rates and manage your financial future.
A credit score is a three-digit rating (300–850) that measures creditworthiness based on five factors: payment history (35%), debt utilization (30%), credit age (15%), inquiry history (10%), and credit mix (10%). Higher scores qualify you for better interest rates.
Step-by-step worked examples
Alex starts with no credit history (no score). Over 2 years, Alex makes all on-time payments and keeps debt low. Alex's score grows from 580 to 720. What changed?
Payment history improved (36 months on-time payments) + credit age increased (24 months active accounts) + debt utilization stayed low (<30% of limits). Result: +140 points.
Blake has a 750 score. Blake misses two credit card payments. What is the likely impact?
Payment history is weighted 35% and directly reflects missed payments. Each missed payment = −100 to −200 points. Blake's score likely drops to 600–650.
Casey has a 680 score and $15,000 in credit card debt across three cards with $20,000 total limits. Casey pays off $10,000. What happens to the score?
Debt utilization drops from 75% to 25%. Utilization is weighted 30%. Casey's score likely rises by 50–100 points to 730–780.

Common mistakes
A credit score of 600 is failing grade. — Correct: 600 is below average but not a failing grade. 670–739 is 'good'; 740+ is 'excellent'.
Checking your credit score damages it. — Correct: Your own inquiries don't affect your score. Only hard inquiries from lenders impact it.
Paying off all debt immediately is always best for your score. — Correct: Paying off accounts completely can lower your score short-term by raising utilization on remaining accounts. Keep low balances instead.
A perfect 850 score is necessary for the best loan rates. — Correct: 740–850 all qualify for the best rates. Reaching 740 is the practical goal.
