Most articles about credit scores spend a lot of time explaining what factors affect your score. Payment history is 35%. Credit utilization is 30%. Length of history is 15%. You've probably read some version of this five times.
What they're shorter on: what to actually do. Concrete steps, ranked by how much they'll move your number.
That's what this is. Let's go through it in order of impact.
Step 1: Check your credit report for errors (highest impact, no cost)
Before you do anything else, pull your actual credit report — not just your score — and look for mistakes. This is the most underrated move in personal finance.
The Consumer Financial Protection Bureau estimates that roughly 1 in 5 Americans have an error on their credit report. That's not a small number. Common errors include: accounts that aren't yours, accounts showing as open that you closed, incorrect late payment records, and debts that were settled but still showing as outstanding.
You can get your free reports from all three bureaus at annualcreditreport.com. Go through each one line by line. If you spot something wrong, dispute it directly with the bureau — Equifax, Experian, and TransUnion all have online dispute portals. Errors can legally be removed within 30 days.
A single disputed and removed error can raise your score by 20–100+ points depending on what it was. Do this first, before anything else.
Step 2: Get your utilization under 30% — ideally under 10%
Credit utilization is the second-biggest factor in your score, and it's also one of the fastest to change. It's simply the percentage of your available credit that you're using.
If your credit card has a $5,000 limit and you have a $2,000 balance, your utilization is 40%. That's hurting your score. Get it under 30% and you'll see an improvement. Get it under 10% and you'll see a bigger one.
A few ways to move the needle here:
- Pay down your balances — obvious, but even a partial payment before your statement closes helps
- Pay twice a month — most people pay once. If you pay a week before your statement closes, your reported balance is lower
- Request a credit limit increase — if your income has gone up since you opened the card, call and ask for a higher limit. This instantly lowers your utilization percentage without you paying a dollar
- Open a new card strategically — adds available credit, but only do this if you can keep the spend low. A hard inquiry will temporarily ding your score slightly.
Step 3: Never miss a payment again — set up autopay today
Payment history is the single biggest factor in your score at 35%. One missed payment can drop your score by 60–110 points and stays on your report for seven years.
The fix is simple and you can do it right now: set up autopay for the minimum payment on every account. Every single one. Not because you'll carry a balance, but so you never accidentally miss a due date and take a massive hit to your score.
You can always pay more manually. But autopay is the safety net. It takes 5 minutes to set up per account and removes human error from the equation entirely.
Step 4: Keep old accounts open
Length of credit history accounts for 15% of your FICO score. The longer your average account age, the better.
The temptation when you pay off a credit card is to close it. Resist this. Unless the card has an annual fee that's not worth it, keep it open and use it occasionally for a small purchase. The age of that account keeps building, and having more available credit helps your utilization.
The one exception: if a card charges an annual fee you're not getting value from, it might be worth closing — but weigh the fee cost against the impact on your average account age before you do it.
Step 5: Limit hard inquiries
Every time you apply for a new credit card, loan, or line of credit, a hard inquiry appears on your report and temporarily lowers your score by a few points. Not a huge deal — typically 5 to 10 points — but it adds up if you're applying for multiple things in a short period.
Shopping for a mortgage or auto loan is an exception: multiple inquiries in a short window (14–45 days depending on the scoring model) are treated as one inquiry for those types of loans, since lenders understand you're rate-shopping.
The practical advice: don't apply for new credit cards when you don't need them, and don't let stores talk you into opening a card for 10% off unless the economics actually make sense.
How long will this take?
Realistically:
- Disputing and removing errors: 30–60 days, can be a large jump
- Reducing utilization: Shows up in the next billing cycle, so 30–60 days
- Consistent payment history: 6–12 months of clean history starts to meaningfully show up
- Building account age: Years, not months — but it accumulates quietly while you do everything else
A 50-point improvement is realistic in 3–6 months if you have errors to dispute and high utilization to bring down. Some people see faster jumps; some slower. What matters is that it moves in the right direction and keeps moving.
What not to do
A few things that seem logical but don't help (or actively hurt):
- Paying someone to "fix" your credit — legitimate credit repair companies can't do anything you can't do yourself for free. Anything promising to remove accurate negative information is a scam.
- Closing cards to "simplify" your finances — this raises utilization and lowers average account age
- Checking your own score repeatedly — soft inquiries from checking your own score don't hurt it at all, so check freely
