How to Improve Your Credit Score: 9 Things That Actually Move the Number
No "secret hacks." Just the factors that genuinely make up your score, ranked by how much they matter — and a realistic timeline for when you'll see the change.
Credit scores feel mysterious because the exact formula is proprietary, but the major scoring models (FICO and VantageScore) have both published the general weighting of what goes into the number for years. There's no trick that moves a score overnight — but there are specific, well-documented actions that reliably help, and others that are mostly myths. Here's what actually works, in rough order of impact.
1. Pay every bill on time — this is the single biggest factor
Payment history makes up roughly 35% of a FICO score, more than any other category. A single payment 30+ days late can stay on your report for up to seven years and can drop a good score by 60-100+ points. If you've never missed a payment, the single highest-value thing you can do is make sure you never do — set up autopay for at least the minimum due on every account, even ones you plan to pay off in full.
2. Bring your credit utilization down — ideally under 30%, lower is better
Credit utilization (your card balances relative to your credit limits) makes up about 30% of a FICO score. This is the factor people can move fastest, because it's based on your balance at the moment your card issuer reports to the bureaus — not your average balance over time. Paying down a balance, or asking for a credit limit increase without using it, can lower utilization within a single billing cycle. Many people aiming for excellent scores keep utilization under 10%.
3. Don't close your oldest credit card
Length of credit history matters (about 15% of a FICO score), and it's calculated using the average age of all your accounts plus the age of your oldest one. Closing your oldest card can shorten your average account age and may also reduce your total available credit, which raises your utilization ratio at the same time — a double hit. If the card has an annual fee you don't want to pay, ask the issuer about downgrading to a no-fee version instead of closing it outright.
4. Don't apply for several new accounts in a short window
New credit inquiries make up about 10% of a FICO score. A single hard inquiry typically costs a few points and fades within a year. The bigger risk is applying for multiple cards or loans in a short period, which signals higher risk to lenders and can compound the point loss. Rate-shopping for a single mortgage or auto loan within a focused window (typically 14-45 days depending on the scoring model) is usually treated as one inquiry, not several — but mixing card applications with loan shopping is not.
5. Mix of credit types helps a little, but don't force it
Credit mix — having both revolving credit (cards) and installment loans (auto, student, mortgage) — makes up about 10% of a FICO score. It's a real factor, but it's also the smallest one on this list, and it is not worth taking out a loan you don't need just to diversify your credit file. This tends to improve naturally over time as you take on a mortgage or auto loan for reasons that have nothing to do with your score.
6. Dispute genuine errors on your credit report
You're entitled to a free copy of your credit report from each of the three major bureaus (Equifax, Experian, TransUnion) at AnnualCreditReport.com — the only site authorized by federal law for this. Errors are more common than people expect: a paid-off collection still showing as open, an account that isn't yours, or a payment marked late that wasn't. Disputing a genuine error (not just a low balance you don't like) can produce one of the few "fast" score improvements available, sometimes within 30-45 days once the bureau investigates.
7. Become an authorized user on a well-managed account
If a family member with a long-standing, low-utilization, on-time-payment card is willing to add you as an authorized user, that account's history can sometimes be reflected on your report — which can meaningfully help if you have a thin or young credit file. This only helps if the primary account is actually managed well; being added to an account with high utilization or missed payments can hurt instead.
8. Keep old, paid-off accounts open if there's no annual fee
Similar to the "don't close your oldest card" point above, but worth calling out separately: a paid-off card sitting unused at $0 balance is doing your utilization ratio a favor by adding to your total available credit, at no cost to you (assuming no annual fee). Many people instinctively close cards they've paid off — this is usually the opposite of what helps your score.
9. Be patient — most of this takes months, not days
Utilization can move within one billing cycle. Payment history, average account age, and the effects of new inquiries take months to fully show up, because they're based on patterns over time rather than single events. If you're rebuilding from a rough patch (collections, missed payments, a high-utilization stretch), expect meaningful score movement over 6-12 months of consistent on-time payments and lower balances rather than weeks.
