Credit scores, in plain English
A credit score is one number trying to answer one question: if we lend this person money, will they pay it back on time? Everything about how it's calculated follows from that. No mystery, no morality — just a prediction.
What the number is made of
| Ingredient | Weight | Plain-English version |
|---|---|---|
| Payment history | ~35% | Do you pay on time? The big one. One 30-day late mark can sting for years. |
| Utilization | ~30% | How much of your card limits you're using. Under 30% is good; under 10% is great. |
| Age of accounts | ~15% | How long you've had credit. This one only improves by waiting. |
| Credit mix | ~10% | Cards plus an installment loan looks more proven than either alone. |
| New applications | ~10% | A burst of applications reads as urgency. Space them out. |
Weights are approximate and vary by scoring model — but the order barely does. Nail the top two and the rest mostly follows.
The two habits that do most of the work
- 1. Autopay at least the minimum on everything. Payment history is a third of the score, and autopay makes a perfect record the default instead of a discipline. Pay more manually whenever you can — the autopay is the safety net.
- 2. Keep card balances low relative to limits. Utilization has no memory — reduce it this month and the score reacts this month. Even paying mid-cycle (before the statement posts) helps, because most issuers report the statement balance.
Myths that refuse to die
"Carrying a balance builds credit."
No. Paying in full builds the exact same payment history and costs $0 in interest. This myth is worth billions a year to card issuers — that's why it survives.
"Checking my own score hurts it."
Checking your own score is a "soft pull" — invisible to the calculation. Only applications for new credit ("hard pulls") count, and even those cost just a few points for a few months.
"Closing old cards helps."
Usually the opposite: closing a card shrinks your total limit (raising utilization) and eventually your average account age. An old no-fee card doing nothing in a drawer is quietly helping. Let it.
"You need debt to have a score."
You need accounts, not debt. One card, used for gas and groceries, paid in full every month, builds an excellent file with zero interest paid — ever.
Starting from nothing (or from a dent)
No file yet? A starter card with a small limit plus twelve months of on-time gas-and-groceries is the well-worn path. Recovering from late marks? They fade in impact every month you stack on-time payments on top — two years of clean history changes the conversation with any lender, including us. Either way, the play is the same: small, boring, on time, repeatedly.
