I took a hit on my credit in my twenties- it was very stupid.
I was working full-time and going to school full-time. Somewhere in there, I signed up for a credit card, probably for a discount at the register, and then I completely forgot I had it. Not “neglected it.” Forgot. Months went by. There was a balance, and I had no memory of the account existing.
By the time I found out, it was in collections.
The amount was small, which is what got me. It wasn’t a crisis; it wasn’t a hardship; it was a small debt I never looked at. But it sat on my credit report, and years later when I went to buy a house, the lender made me write a letter explaining why I had waited so long to pay it.
My letter said, essentially: I have no idea.
I learned two lessons from it- credit damage can happen without you noticing and, if you don’t have systems in place, small things quietly become big things.
What a Credit Score Actually Is
A credit score is a three-digit number, usually between 300 and 850, that predicts how likely you are to repay borrowed money.
That’s the whole thing. It isn’t a measure of your worth, your character, or how responsible you are as a person. It’s a statistical prediction built from your past behavior with borrowed money, and it’s worth holding onto that framing, because people carry a lot of shame about this number that it doesn’t deserve.
The most common version is the FICO score, used by roughly 90% of major U.S. lenders. There’s also VantageScore, which has been gaining ground fast in the mortgage market, and I’ll come back to that in the next post because something significant just changed there.
The FICO ranges are:
800 and up is exceptional,
740 to 799 is very good,
670 to 739 is good,
580 to 669 is fair, and
Below 580 is poor.
The national average is currently 714, which sits in the “good” band. If you’re near there, you’re near the middle of the country.
The Five Things It’s Built From
Every FICO score comes from five categories. The percentages below are the general weights FICO publishes, and they shift somewhat depending on your particular credit profile, so treat it as an approximation:
Payment history, 35%: The biggest piece by far. Have you paid on time? Late payments, collections, and bankruptcies all live here. A single payment that goes 30 days late can cost you a meaningful number of points, and here’s the counterintuitive part: the better your score, the more a single miss takes from you. There’s more to lose from the top.
How much you owe: 30%: Mostly, this is credit utilization, meaning how much of your available credit you’re currently using. A $3,000 balance against a $10,000 limit is 30% utilization. So it may seem strange, but this is a key component - if you don’t use credit, it hurts you.
You’ll hear that 30% is the magic threshold. It’s a useful rule of thumb, but it isn’t a cliff. FICO doesn’t flip a switch at 29.9%. Lower is simply better all the way down, so treat 30% as a ceiling to get under rather than a target to hit.
Length of credit history: 15%. Older accounts generally help, which is where the advice about not closing your oldest card comes from. That advice is right, but the usual explanation for it is wrong. Closing a card in good standing doesn’t erase its history. Closed accounts stay on your report for years and keep counting.
The real risk is more immediate. When you close a card, you lose its credit limit, and your utilization on everything else jumps overnight. That’s what actually costs you points.
Credit mix, 10%: Whether you’ve handled different kinds of credit- cards, an auto loan, a mortgage- don’t open accounts to improve this. It’s only ten percent.
New credit, 10%: Recent applications and hard inquiries. A burst of applications in a short window reads as risk.
Payment history and utilization together account for roughly two-thirds of the model, and they’re where your day-to-day decisions have the most influence. You can’t undo a late payment from four years ago. You can decide what happens this month.
You Don’t Have One Credit Score
This surprises people, and it’s worth knowing before you go looking.
There isn’t a single number. Dozens of scoring models exist, and different lenders use different ones. The FICO version a mortgage lender pulls may not match the version your auto lender uses, and neither may match the VantageScore your credit card app shows you for free.
So don’t be alarmed if the number in your banking app doesn’t line up with what a lender quotes you. They’re measuring the same behavior with different rulers. What matters is the direction you’re moving, not matching a specific number across every source.
Why This Matters More at Our Age, Not Less
Most credit score advice is written for someone in their twenties trying to finance a first car. If you’re in your forties, fifties, or sixties, you may assume this is no longer a problem.
It isn’t, and the stakes are arguably higher now since they (rightly or wrongly) affect.
Interest rates on everything: On a 30-year mortgage, the gap between a mediocre score and a strong one can run into tens of thousands of dollars over the life of the loan: same house, same schedule, different number on a form.
Insurance premiums: Many auto and homeowners insurers use credit-based insurance scores, which are derived from your credit history but aren't the same as the FICO score in your banking app. State rules vary widely, and some states restrict or prohibit the practice entirely. Where it’s permitted, weaker credit can mean a higher premium on a car you’ve driven safely for fifteen years.
Renting: If you sell the house and rent for a while, which plenty of people do between homes or after a divorce, landlords check credit routinely. Weak credit means a rejection or a much larger deposit.
Utility and phone deposits: Poor credit can mean putting money down to turn the lights on.
Employment screening: Some employers review credit history as part of a background check, subject to federal and state rules and generally requiring your written permission.
And one that belongs specifically to this stage of life.
Sort out any borrowing you’ll need before your paycheck stops.
I want to be careful here, because there’s a myth floating around that retirement makes you unmortgageable. It doesn’t. Fannie Mae and Freddie Mac both allow retirement distributions to count as qualifying income, and in some circumstances retirement assets themselves can be converted into an income stream for underwriting purposes.
What changes is the paperwork and the proof. Lenders may want a history of distributions rather than an intention to start them, evidence that the income will continue, and documentation you didn’t need when a W-2 did the talking. If you haven’t started taking distributions yet, you may need to establish a track record first, and that takes time you won’t have in the middle of a transaction.
So if a mortgage, a refinance, or a HELOC is anywhere in your plans, learn how your lender will actually underwrite you before you retire, rather than assuming the process works the same afterward. It can work. It just works differently, and finding that out during a closing is the expensive way.
Your Report and Your Score Are Two Different Things
One more point, people use credit report and score interchangeably, and they shouldn’t:
Your credit report is the record: every account, every payment, every inquiry, every collection.
Your credit score is a number calculated from that record.
You need to look at both, for different reasons. The report tells you whether the information is accurate. The score tells you where you stand.
This matters because if there are errors on your report- wrong late payments, accounts that aren’t yours, debts listed twice- those errors are dragging the score down. And you’ll never find them by looking at the score alone. The score tells you something’s wrong, not what.
You can pull your credit reports weekly, at no cost, from all three bureaus at AnnualCreditReport.com. That expanded access became permanent in 2023. It’s the only federally authorized site, and it won’t ask you for a credit card.
For the actual score, several free options exist. Credit Karma gives you VantageScores from TransUnion and Equifax. Capital One’s CreditWise is free to anyone, not just their customers. Many banks and card issuers now show a FICO score right in their app, so check what you already have before signing up for anything new.
Checking your own credit does not hurt your score. That’s a soft inquiry, and the scoring models don’t see it. Only applications for new credit count against you. I mention this because the belief that looking will hurt you keeps a remarkable number of people from ever looking, which is exactly backward.
Go Look
If you’ve been avoiding this because you’re afraid of what you’ll find, I understand the impulse. I’d still look.
Pull your three reports at AnnualCreditReport.com. Find your score through your bank or one of the free services. Read the reports, not just the number, and flag anything you don’t recognize.
If you find errors, dispute them. It’s free, the bureaus are legally required to investigate, and it’s the fastest way to move a score.
I had a collections account sitting on my report for years over a card I forgot existed. Nobody called to tell me. I found out when a lender made me explain it in writing.
Next time we’ll look at what’s happening to credit scores across the country right now, including a change to mortgage scoring that landed this week.
