Credit repair expert and influencer Micah Smith cautions that aggressively paying off car loans, mortgages, or student loans can unexpectedly damage your credit score — even though the move feels like a responsible step toward financial freedom.

When financial anxiety rises, the instinct to eliminate installment debt quickly seems prudent. However, Smith explains that closing installment loan accounts can suppress credit scores by reducing credit mix diversity and halting active positive payment history.

Smith, who spoke with Fox News Digital, says transforming a credit profile from the 400s into the 700s in as little as one month is achievable — but it requires precise timing, strategic balance management, and an understanding of mechanisms embedded in consumer credit law. On the standard FICO scoring scale of 300 to 850, a leap from the 400s to the 700s can mark the difference between subprime borrowing costs and access to prime interest rates on mortgages, auto financing, and credit cards.

"It really takes a deep understanding of how credit works, but 400s to 700s is very realistic," Smith told Fox News Digital.

"The biggest thing we look at right away is, how is the positive credit being used? Is there any positive credit there? Then we take a look at the negative items. What kind of negative items are there?" she continued. "You really want to assess those two things… and are there any quick wins available on the credit report?"

Understanding the FICO Score Breakdown

Smith has previously explained that credit utilization — or amounts owed — accounts for 30% of a standard FICO credit score, while payment history makes up 35%. Credit mix diversity contributes approximately 10%, and the remaining 25% is split between length of credit history (15%) and new credit inquiries (10%).

A critical but often overlooked detail: credit card issuers report account balances to credit bureaus once per month on the account's statement closing date — not the payment due date. This timing distinction is essential for anyone seeking a rapid score improvement, because even cardholders who pay in full each month can appear overextended if their balance is high on the reporting date.

Smith emphasizes that maintaining an overall utilization ratio below 10%, and ideally under 7%, signals low credit risk and yields maximum point gains in scoring models.

"Most people don't realize how much their credit card usage is impacting their credit score," she said. "You can call your credit card company and say, 'When is my closing date?' And… you wanna get your balance down to 6% utilization or less. So if you have a $1,000 credit card, you want that balance to be $60."

Requesting Credit Limit Increases

"The other thing you can do is, if you're eligible, you actually also can ask for a credit limit increase to widen that gap. So that way the balanced limit ratio, you can widen it by asking for a credit limit increases. If it's an inquiry, it's not that big of a deal. It's two to five points. It's nominal. But sometimes, that can actually increase a person's credit score by not having to part ways with a ton of money."

Smith also referenced a June 2026 LendingTree survey, which found that 84% of credit cardholders who requested an interest rate (APR) reduction were successful, yet only 23% of cardholders actually made the request.

"You can help yourself by picking up the phone, making a phone call, and you can actually pay down your debt a lot faster just by simply asking for a reduction in the interest," she noted.

"Half the money that you win or lose in life will be done at the negotiation table. So I would take a look at all of your bills, see what can be negotiated. People underestimate — rent can be negotiated, utilities can be negotiated, credit cards can be negotiated."

The Installment Loan Trap

Installment loans — including mortgages, auto loans, and student loans — function differently from revolving credit such as credit cards. When an installment loan is paid off, the account status changes to "closed," which can reduce credit mix diversity and pause active positive payment reporting. While closed accounts in good standing generally remain on a credit report for up to ten years, the cessation of ongoing on-time payment activity can still produce a measurable — and often surprising — downward adjustment.

"The most common mistakes that we see in credit today that backfire badly would blow your mind… They will actually have enough money to pay off student loans in full. They'll have enough to pay off their cars in full, they might have enough money to pay off their mortgage in full thinking that they're going to drive their credit scores up. And actually, it takes the credit scores backwards," she warned.

"When you pay off an installment loan, it's closed. So that positive history, it stops calculating into the credit score. And so you actually end up suppressing the score," Smith continued. "This is why it's so important to know where to apply the appropriate funds, because if you apply it in the wrong places, thinking it's going to drive the credit score upwards, you're going to find yourself very, very disappointed."

Long-Term Strategy Over Quick Fixes

While a rapid score boost can deliver an immediate surge of confidence, Smith stresses that a 30-day triage plan is only the initial step. Sustaining credit improvements requires shifting from temporary fixes to automated financial systems and habitual practices.

"Short-term fixes, those are amazing. We're so grateful when we get these really quick short-term fixes, but it ultimately hasn't addressed the underlying problem," she said. "People need to be reminded more than they're taught… It's not because you understand credit so well, it's because you don't and you haven't built the habits yet. And so we're reinforcing those habits day after day, week after week, month after month. And so we're constantly focused on reminding more than teaching, and I think that's a very important principle that we all need to know."
