A single collection account typically drops a credit score anywhere from about 50 points to more than 150 points, and the exact hit depends heavily on how strong your credit was before the collection landed. The higher your starting score, the further it tends to fall. FICO does not publish a fixed formula, so no one can quote you a precise number, but credit analysts consistently observe that the damage is relative to your starting position.
How the Point Drop Breaks Down by Starting Score
If your score sits in the high 700s or above, a single collection can cause a dramatic decline, often estimated at 100 points or more. The scoring algorithm treats the new delinquency as a sharp break from an otherwise clean payment history, and clean histories have the most to lose.
If your score is already in the fair or poor range, roughly 550 to 620, a new collection still hurts, but the drop is smaller. Estimates commonly land between 50 and 75 points. Your profile already signals risk, so one more negative mark tells the algorithm less that it didn’t already know.
Either way, the damage is front-loaded. Your score drops most sharply in the first few months after the collection is reported, and the pull weakens as the account ages. Scoring formulas weigh recent activity more heavily than older entries, so a collection from last month hurts far more than one from four years ago, even if you do nothing about it.
What Changes the Size of the Hit
Beyond your starting score, four things move the number: the scoring model your lender uses, the type of debt, the balance, and whether the account is paid or unpaid.
Which Scoring Model the Lender Runs
You can have several credit scores at the same time, and they can differ sharply because the models treat collections differently.
FICO Score 8, still the most widely used version, treats paid and unpaid collections the same way. Both lower your score, and paying does not undo the damage. FICO Score 9 and FICO Score 10 completely ignore paid collections, dropping them out of the calculation entirely. Unpaid medical collections also carry less weight under those newer models.1myFICO. How Do Collections Affect Your Credit
VantageScore has excluded all paid collections, including medical, since version 3.0 launched in 2013.2VantageScore. Policy Makers and VantageScore VantageScore 4.0 also reduces the impact of unpaid medical collections by up to approximately 24 points compared with how it would otherwise score them.
This matters for mortgages in particular. Mortgage lenders have historically relied on older FICO models where paid collections still count against you. The Federal Housing Finance Agency has been working to transition Fannie Mae and Freddie Mac to FICO 10T and VantageScore 4.0, but full implementation is not finished. During the interim, lenders can deliver loans using either the classic FICO model or VantageScore 4.0.3FHFA. Credit Scores Until the transition wraps up, many mortgage borrowers will still be evaluated under models that penalize paid collections.
The Balance on the Account
Not every collection hits your score at all. FICO Score 8 and all newer FICO models ignore collections with an original balance under $100, treating them as nuisance debts that don’t predict future credit risk.1myFICO. How Do Collections Affect Your Credit VantageScore 3.0 and 4.0 set the bar higher, ignoring collections under $250. So a small unpaid parking ticket or unreturned equipment fee will not tank your score under these models.
Ignored by the formula does not mean invisible. The collection still appears on your credit report, and a human underwriter reviewing your file for a mortgage or another large loan can see it and factor it in.
Medical vs. Non-Medical Debt
Medical collections follow different rules than credit card, utility, or other consumer debts. In 2023, Equifax, Experian, and TransUnion voluntarily adopted policies that significantly reduce the credit impact of medical debt:4Consumer Financial Protection Bureau. Have Medical Debt? Anything Already Paid or Under $500 Should No Longer Be on Your Credit Report
- All three bureaus remove medical collections once they’re paid, regardless of the original balance.
- Unpaid medical collections under $500 do not appear on credit reports.
- Medical debt less than one year old is excluded from credit reports, giving you time to work through insurance disputes or set up a payment plan before any credit damage occurs.
The CFPB tried to go further in 2025 by finalizing a rule that would have banned all medical debt from credit reports. A federal court vacated that rule in July 2025, finding the agency had exceeded its authority under the Fair Credit Reporting Act.5Consumer Financial Protection Bureau.

Non-medical consumer debts get none of these protections. An unpaid gym membership, utility bill, or credit card balance can be reported shortly after a collection agency acquires the account. No waiting period, no balance threshold.
Paid vs. Unpaid
When you resolve a collection, the account updates to “paid in full” if you satisfied the balance, or “settled” if the creditor accepted less than the full amount, often between 30% and 60% of the original debt.
Whether paying helps your score depends on the model. Under FICO 9, FICO 10, and VantageScore 3.0 and 4.0, a paid collection drops out of the calculation, which can produce a meaningful improvement. Under FICO 8, paying or settling doesn’t move the score itself. The collection still counts. A “paid” status is still better than “unpaid” in the eyes of any human underwriter looking at the file.1myFICO. How Do Collections Affect Your Credit
How Fast the Damage Fades
Under the Fair Credit Reporting Act, a collection can remain on your credit report for up to seven years. The clock starts 180 days after the original delinquency that led to the collection, not when the collection agency first reported it.6Office of the Law Revision Counsel. United States Code Title 15 – Section 1681c Once the seven-year window closes, the collection must come off automatically.
The negative pull weakens well before then. Because scoring models weigh recent activity heavily, an aging collection gradually loses power even if you never pay it.
If you do pay off the collection, and you’re scored under a model that drops paid collections, your score may begin recovering within one to two billing cycles, roughly 30 to 60 days. More noticeable improvement typically shows up over the following 3 to 12 months, assuming you keep other accounts in good standing. Rebuilding from more serious damage, like multiple collections or a bankruptcy alongside collections, takes longer and depends on how consistently you make on-time payments going forward.
Check the Statute of Limitations Before Paying an Old Debt
Before making any payment on an old collection, check whether the debt has passed your state’s statute of limitations for lawsuits. Depending on the state and type of debt, creditors typically have between three and ten years to sue for an unpaid balance. In many states, making even a small partial payment on an old debt can restart that clock entirely, giving the collector a fresh window to take you to court. If a debt is already past the statute of limitations, a partial payment made in hopes of a score boost could reopen legal exposure you had already outlived.
