Can You Refinance a Personal Loan at a Bank?

Yes, you can refinance a personal loan at a bank if the bank offers a suitable new loan and approves your application. Refinancing means using a new loan to pay off the existing one; this calculator estimates the new loan’s monthly payment and total interest from its amount, APR, and term.

Formula

The calculator uses the standard fixed-payment loan formula. It estimates a monthly payment from the amount borrowed, annual percentage rate, and number of monthly payments:

Monthly payment = P × r ÷ [1 − (1 + r)⁻ⁿ]

Total interest = monthly payment × n − P

• P is the new loan amount, in dollars.
• r is the monthly interest rate, calculated as APR ÷ 1,200.
• n is the term in months, calculated as years × 12.

The figures are estimates based on the inputs. The calculator does not determine whether a bank offers refinancing or whether it will approve an application. For a real comparison, use the proposed loan amount, APR, term, and any applicable charges supplied in the lender’s disclosure.

Worked Example

Using the calculator’s defaults—$20,000, an 8% APR, and a five-year term:

1. Convert APR to a monthly rate: 8 ÷ 1,200 = 0.0066667.
2. Convert the term to payments: 5 × 12 = 60 months.
3. Apply the payment formula: $20,000 × 0.0066667 ÷ [1 − (1.0066667)⁻⁶⁰] = approximately $405.53 per month.
4. Calculate interest using the unrounded formula payment: $405.530… × 60 − $20,000 = approximately $4,331.80.

The displayed payment is rounded to cents. As a result, multiplying the displayed $405.53 by 60 gives $24,331.80 in total payments, or $4,331.80 above the principal. Actual payment schedules can differ slightly because of rounding and lender-specific calculation methods.

Assumptions

• The APR and payment amount remain fixed for the full term.
• Payments are made monthly and on schedule.
• Interest is modelled monthly at APR divided by 12.
• The estimate excludes fees and other charges; it does not model taxes, insurance, PMI, or escrow.

How Personal Loan Refinancing Works at a Bank

With refinancing, you apply for a new personal loan and, if approved, use its proceeds to pay off the balance on your existing loan. Depending on the bank’s process, funds may be sent to you to handle the payoff or sent directly to the current lender. Confirm the payoff procedure and timing before treating the old debt as settled.

A refinance is different from changing the terms of your existing loan. The original loan generally remains in place until it is paid off, while the new loan has its own agreement, repayment schedule, and costs. The amount needed to clear the old loan may differ from the balance shown on a recent statement because interest can accrue between the statement date and payoff date.

Banks do not all offer personal loans or refinancing for existing personal loans. Check whether the bank accepts applications for this purpose, whether it will refinance a loan from another institution or its own loan, and how it handles payoff funds. Approval and offered terms depend on the application and the lender’s assessment; a calculator cannot predict them.

What to Compare Before Applying

A lower monthly payment alone does not establish that a refinance costs less overall. A longer repayment term can reduce each payment while increasing the time interest accrues. Compare the complete proposed repayment cost with the amount and schedule remaining on the current loan.

• Payoff amount: Ask the current lender for a dated payoff quote and how long it remains valid.
• APR and charges: Review the proposed APR and all disclosed origination or other fees. A fee may affect the amount you receive or the amount you need to borrow.
• Term and total payments: Compare the number of payments and the total of scheduled payments, not just the monthly figure.
• Early payoff details: Check the existing agreement for any charge or condition associated with paying it off early.
• Loan purpose and restrictions: Confirm that the bank allows the funds to pay off the existing personal loan and understand any relevant conditions.

For example, imagine a remaining balance of $8,000 and 24 payments left on the current loan. A new loan might have a lower monthly payment because it stretches repayment over 48 months. That change does not by itself show savings: compare the total remaining payments on the old loan with the new loan’s total payments plus applicable charges.

Common Problems and Misconceptions

“A lower payment means I pay less.” Not necessarily. A longer term can lower the payment but increase total interest. The calculator makes that tradeoff visible when you enter different terms, but it cannot account for charges unless you include them in the loan amount or compare them separately.

“The balance is the payoff amount.” It may not be. Ask the current lender for the exact amount and deadline. If the new loan is too small to cover the payoff and any financed charges, you may need another way to cover the difference.

Other practical issues include a delay in funding, a missed payment while the payoff is processing, or accidentally continuing automatic payments after the balance is cleared. Ask both lenders about timing and payment instructions. Keep records and verify that the old loan shows a zero balance; do not assume that applying for a refinance closes it.

Alternatives and When to Use the Calculator

If a bank does not offer refinancing, or its proposed terms do not fit your comparison, other possibilities include asking the current lender about available repayment options, making extra payments if permitted by the agreement, or checking whether another type of lender offers a personal loan. Each option has its own terms and eligibility process. Compare written disclosures rather than assuming that one category of lender will offer particular rates or fees.

Use this calculator to estimate the payment and interest for a hypothetical new loan, or to check how changing the amount, APR, or term changes those estimates. It is most useful after you have figures from an actual offer. It does not include the current loan’s remaining schedule, payoff quote, fees, or application outcome, so those details require a separate comparison.

Frequently Asked Questions

Can I refinance a personal loan with the same bank?
Possibly, but banks set their own product and application rules. Ask whether the bank refinances its own personal loans and whether the new application would pay off the existing balance.

Does a bank have to offer personal loan refinancing?
No. A bank may offer personal loans without offering a specific refinancing product, or may limit which existing loans can be paid off. Confirm availability directly with the bank.

Can refinancing lower my monthly payment?
It can if the new loan has a lower payment, for example because its rate or term differs. A longer term may also mean more total interest, so compare the full repayment costs and charges.

Can I refinance a personal loan with a higher balance?
A new loan may be sized to cover a payoff amount and charges if the lender allows it and approves the requested amount. Borrowing more increases the debt; check the offer’s amount, purpose, and cost carefully.

How do I know whether refinancing saves money?
Compare the total payments remaining on the existing loan with the new loan’s total payments and applicable fees, using the exact payoff amount and proposed terms. A lower monthly payment by itself is not enough to establish a lower total cost.

This result is an estimate; the lender’s disclosure gives the exact figures.
