How Your Score Is Calculated
Your FICO score breaks down into five weighted components:
• Payment history (35%) — Have you paid on time? • Credit utilization (30%) — How much of your available credit are you using? • Length of credit history (15%) — How old are your accounts? • Credit mix (10%) — Do you have different types of credit? • New credit inquiries (10%) — Have you applied for new credit recently?
Focusing on the top two factors — payment history and utilization — drives the biggest improvements.
The Utilization Secret
Credit utilization — the percentage of available credit you're using — has an outsized impact. Keeping utilization below 30% is the common advice, but below 10% scores even better. If you have a $10,000 credit limit, keeping your balance below $1,000 maximizes this factor. A simple trick: make payments twice monthly instead of once to keep reported balances low.
What Doesn't Affect Your Score
Common myths debunked:
• Checking your own credit score (soft inquiry — no impact) • Your income or employment status • Your savings or investment accounts • Debit card usage • Being denied credit (only the inquiry matters, not the result) • Rent payments (unless you use a reporting service)
Understanding what doesn't matter prevents unnecessary anxiety.
Building and Rebuilding Credit
For thin credit files or rebuilding after damage: secured credit cards require a deposit but report to all three bureaus. Become an authorized user on a family member's long-standing account. Credit builder loans from credit unions report positive payment history. Consistency is key — six months of perfect behavior shows meaningful improvement, and most negative items have diminishing impact after two years.
