The Complete Credit Score Impact Cheat Sheet
Every credit decision has a measurable consequence. The problem is that most people don't know the actual numbers until after they've already acted. This guide gives you the real impact ranges for each major credit event — and what to do strategically before making any move.
| Action | Score Impact | Duration |
|---|---|---|
| Pay off credit card | +20 to +50 pts | Permanent (while balance stays low) |
| Successfully dispute an error | +10 to +100 pts | Permanent (item removed) |
| Pay off collection (FICO 9) | +20 to +80 pts | Permanent (model-dependent) |
| Become authorized user | +10 to +40 pts | While account remains active |
| Open new credit card | −5 to −10 pts | Temporary: 6–12 months |
| Hard inquiry | −3 to −10 pts | Temporary: up to 12 months |
| Close old credit card | −5 to −25 pts | Permanent (utilization + age change) |
| Miss one payment (30 days) | −60 to −110 pts | 7 years (fades significantly after 2) |
| Collection or charge-off | −80 to −150 pts | 7 years from original delinquency |
| Bankruptcy (Chapter 7) | −130 to −200 pts | 10 years on report |
The Actions That Hurt Your Score
Missing a Payment (30 Days Late): −60 to −110 Points
This is the single most damaging common credit event. Payment history is 35% of your FICO score — the largest single factor — and a missed payment is direct evidence against it. The impact is counterintuitively larger for people with higher scores. A perfect 780 can drop to 670–700 from a single 30-day late. A 600 score might only drop 40–50 points.
What to do if this happens: Pay immediately, even if late. Then call the lender and request a "goodwill adjustment" — asking them to remove the late mark as a courtesy. If it's your first late payment in a long history of on-time payments, many lenders will grant this. Get any agreement in writing.
Closing an Old Credit Card: −5 to −25 Points
Closing a card removes its available credit limit from your utilization calculation and may shorten your average account age. Both are negative. The impact is larger if the card was your oldest account or if its limit represents a significant portion of your total available credit.
What to do instead: Ask for a product change — downgrade to a no-annual-fee version of the same card. This keeps the account history and available credit intact without paying a fee. If no no-fee version exists, keep the card open with a small recurring charge (a streaming subscription) to avoid closure for inactivity.
Hard Inquiries: −3 to −10 Points (Temporary)
The impact is small and temporary. Most inquiries stop affecting your score after 12 months and fall off your report entirely after 24. If you're shopping for a mortgage, auto loan, or student loan, submitting multiple applications within 14–45 days counts as a single inquiry — the models understand rate-shopping behavior.
Bankruptcy: −130 to −200 Points
Among the most severe single-event drops. Chapter 7 stays 10 years; Chapter 13 stays 7 years. However — many people's scores begin recovering within 12–18 months of filing, because the bankruptcy clears unmanageable debt and allows positive payment history to accumulate. It's a drastic step with a long-term impact, but it's sometimes the right financial decision despite the credit cost.
The Actions That Help Your Score
Paying Off a Credit Card: +20 to +50 Points
Paying off a card lowers your utilization ratio, which is 30% of your score. This improvement is visible within one to two billing cycles. The impact is largest when the card was at high utilization (above 50%) and when the card represents a significant portion of your total available credit. After paying it off, keep the account open — closing it would undo part of the benefit.
Disputing an Error: +10 to +100 Points
Removing an inaccurate negative item can produce the largest single score improvement available — potentially bigger than any other action. The exact improvement depends on what was removed. A wrongly reported collection account that gets deleted could add 50–100 points. A late payment reported in error that gets removed can add 30–60 points.
You have the right under the Fair Credit Reporting Act to dispute any inaccurate item with all three credit bureaus. Always dispute by certified mail rather than online portals. Online dispute systems require agreeing to terms that may waive important FCRA rights and don't create the legal paper trail you need if the bureau fails to respond within 30 days.
Paying a Collection Account: 0 to +80 Points
This is the most nuanced scenario because the impact varies dramatically by scoring model. Under FICO 8 (the most widely used model for lending decisions), paid and unpaid collections are weighted similarly. Under FICO 9 and VantageScore 4.0, paid collections are ignored entirely — which can produce a significant improvement.
The strategic move before paying any collection: attempt to negotiate "pay for delete" in writing. A pay-for-delete agreement means the collector removes the entry from your report entirely in exchange for payment. A deleted entry is better than a paid entry under every scoring model. Get the agreement in writing before sending any payment.
Also verify the collector is legitimate before paying anything. Check our FTC Banned Collectors List — over 170 agencies have been permanently banned from debt collection.
Why the Same Action Can Have Different Impacts
The same credit event can produce very different score changes depending on your starting score and credit history. Here's why:
- Higher scores have more to lose. Someone at 780 experiences a larger drop from a missed payment than someone at 600, because the scoring model treats the late as a more unexpected signal from someone with a perfect history.
- Thin files are more volatile. If you have only 2–3 accounts on your report, any single change has an outsized effect. Thicker files with more positive history absorb negative events better.
- Utilization changes are immediate. Unlike most credit events that involve waiting for reporting cycles, paying down a balance produces a score change as soon as the creditor reports the lower balance — typically within one billing cycle.
- Scoring model version matters. FICO 8, FICO 9, FICO 10, and VantageScore 3.0 and 4.0 all treat certain factors differently. Mortgage lenders typically use older FICO versions. Auto lenders often use industry-specific models. The simulator uses FICO 8 as the reference since it's the most widely used model overall.
