5 Common Personal Loan Refinancing Mistakes to Avoid

Mistake 1: Optimizing for the monthly payment, not total cost 

The monthly payment is the immediate number a borrower is faced with in the short term. However, making a decision solely to bring down monthly payments without considering total overall cost can be a potential error when evaluating a refinance. 

A lower payment can be achieved simply by extending your loan term, even if your Annual Percentage Rate (APR) stays the same or goes up. More months of interest can lead to a higher total cost, even though the payment looks smaller. 

How to avoid it: Comparing total interest paid across the full term of each option, not just the monthly payment, is generally recommended. Refinancing can potentially reduce both. If the only improvement is a lower monthly payment from a longer term, there is a cost trade-off involved. 

Mistake 2: Refinancing too close to payoff 

Personal-loan interest is usually front-loaded—early payments are mostly interest, and later payments mostly principal. In the later stages of a loan term, it is likely that most of the interest has already been paid. 

Refinancing late, in specific circumstances, could be suboptimal because there’s little interest left to save. 

How to avoid it: Refinancing can be viable earlier in your term. Usually, the further from payoff you are, the higher the remaining interest that can be impacted with a lower rate. 

Mistake 3: Applying to multiple lenders with full applications 

Submitting full applications to multiple lenders can trigger hard credit inquiries. However, FICO treats multiple inquiries for the same loan type within a 14-to-45-day window as a single inquiry, so the credit score impact of rate shopping is usually limited when done within that timeframe. The more practical issue is efficiency: full applications tend to require income and identity documentation, and submitting several at once is time-consuming. 

How to avoid it: You may check your rate with two or three lenders who use soft inquiries first. You usually get an estimated APR and loan terms. You may then submit a full application to the lender you would like to proceed with. If you do apply to more than one, it is advisable to keep the applications within a two-week window, as submitting multiple applications within a 14-day window can count as a single inquiry under FICO's rate-shopping treatment. However, this depends on the FICO score model being used by the lender 

Mistake 4: Not checking for a prepayment penalty on the existing loan 

Some loans may charge a prepayment penalty for paying off the balance early: typically a percentage of the remaining principal or several months of interest. If your current loan has a prepayment penalty, that cost has to be included in your refinancing calculation. 

How to avoid it: You may check your original loan agreement before you start comparing refinancing options. If a prepayment penalty applies, that cost will influence the total-cost comparison. 

Mistake 5: Not confirming how your old loan will be paid off  

When you refinance, the new loan needs to clear the existing one—but who handles that depends on the lender. Some lenders disburse funds directly to pay off the old loan on your behalf. Others deposit the proceeds into your bank account and leave the payoff to you. If you assume the process is automatic and it isn't, you risk the old loan continuing to accrue interest, a missed payment appearing on your credit report, or both loans running simultaneously for longer than intended. 

How to avoid it:  If the proceeds are deposited to your bank account, paying off the old loan promptly and confirming with both lenders that the account has been closed can help avoid the old loan accruing further interest or a gap in payment records.

Frequently asked questions 

Should I refinance my personal loan? 

It depends on your situation. It can be viable when your credit has improved, when rates have dropped, or when your current payment is difficult to manage. It may not be viable when you’re close to payoff or when the only improvement is a longer term that increases total interest. 

What are the pros and cons of refinancing a personal loan? 

Pros typically include a potentially lower APR, a lower monthly payment, and savings on total interest. The cons include a possible increase in total cost with longer terms, and low interest savings in case the refinancing is done late. However, all of these depend on your specific circumstances. 

Is there a personal loan refinance checklist? 

Yes, you can use a series of principles as a checklist. The key steps are checking your current loan for prepayment penalties, pre-qualifying with soft inquiries to compare real offers, and comparing total cost (not just monthly payment) before deciding.
