Loan refinance interest rates vary by lender, loan type, borrower, and the terms of the new loan; there is no single rate that applies to every bank. This calculator estimates the monthly payment and total interest on a refinance loan when you enter its amount, APR, and term—use a rate quoted by a lender for a personalized estimate.

Formula

The calculator applies the standard fixed-rate, fully amortizing loan payment formula. It estimates the payment from the new balance, annual percentage rate (APR), and number of monthly payments:

  • Monthly payment: M = P × r ÷ [1 − (1 + r)−n]
  • Total interest: I = (M × n) − P
  • Monthly rate: r = APR ÷ 1,200
  • Number of payments: n = years × 12

P is the refinance loan amount in dollars, APR is the annual percentage rate entered as a percentage, r is the monthly rate as a decimal, n is the number of monthly payments, M is the estimated monthly principal-and-interest payment in dollars, and I is total interest in dollars. The displayed payment is rounded to cents; total interest uses that rounded payment multiplied by the number of payments, then subtracts the starting balance.

Worked Example

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

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

The calculator therefore displays an estimated monthly payment of $405.53 and total interest of $4,331.80 for these inputs. The example rate is only a neutral calculation input, not a claim about any bank’s current or typical offer.

Assumptions

  • The APR is fixed for the entire term.
  • Payments are made monthly, with the first payment one month after the loan begins.
  • Interest accrues monthly at APR divided by 12.
  • The calculation covers principal and interest only. It excludes lender fees, taxes, insurance, escrow, and any other charges not entered as inputs.

Why Refinance Rates Differ by Bank

A bank’s advertised or quoted refinance rate is not a universal rate available to every applicant. Lenders assess applications under their own pricing methods, while the loan itself also matters: refinancing a car, a home, student debt, or an unsecured personal loan involves different products and terms. A rate can also depend on details such as the requested amount, repayment period, collateral, and the borrower’s application profile.

Rates and offers change over time. A rate shown in a past advertisement, on a comparison site, or in an old account statement may not be available now, and an advertised figure may depend on conditions that do not apply to every applicant. To compare banks accurately, request current written quotes for the same loan type, balance, repayment term, and relevant rate structure. This article does not quote or predict current rates.

How to Compare Refinance Offers

Compare the full loan terms, not just the headline interest rate or monthly payment. A longer term can lower the scheduled payment while increasing the number of months during which interest accrues. Fees can also change the effective cost or the amount that must be borrowed.

  • Match the inputs: Compare the same loan amount and repayment term wherever possible.
  • Check the rate type: Confirm whether a quoted rate is fixed or variable and how any rate changes are described in the lender’s documents.
  • Review costs: Ask which application, origination, closing, or other charges apply, and whether they are paid upfront or added to the balance.
  • Separate payment from total cost: Compare the monthly payment alongside total payments, interest, and fees over the full term.
  • Verify payoff details: For an existing loan, get its current payoff amount rather than relying only on the balance shown on an earlier statement.

For example, a lower payment on a longer-term refinance does not by itself show that the loan costs less overall. Use the calculator to estimate principal-and-interest costs, then account separately for lender charges and any other terms in the written offer.

Limits, Fees, and Common Comparisons

This calculator needs the new loan amount, APR, and term. It does not search bank rates, determine eligibility, or predict an approval decision. The APR must come from a lender quote or another source the reader can verify. If the lender gives a rate that can change, a single fixed-rate estimate cannot show future payment changes.

The estimate also excludes fees. If charges are financed, they may increase the loan amount and therefore affect the payment and interest. If charges are paid upfront, they are still part of the cost of refinancing even though they do not appear in the calculator’s outputs. Check the lender’s disclosures to understand the complete amount due and the payment schedule.

When comparing an existing loan with a refinance offer, compare remaining costs on the old loan against the new loan’s payments and fees over a consistent period. The calculator can model the new loan’s principal-and-interest schedule, but it does not calculate the old loan’s remaining interest, early payoff charges, or a break-even point. Those require additional figures from the relevant loan documents.

Frequently Asked Questions

What are loan refinance interest rates by bank?
They are the rates individual lenders quote for refinancing a specific loan and application. They vary by product and terms, and there is no single rate that applies to all banks or borrowers. Obtain current quotes directly from lenders to compare actual offers.

Does refinancing always lower the interest rate?
No. The new rate may be higher or lower than the existing loan’s rate. Even when a quoted rate is lower, fees, a longer repayment term, or other contract terms can affect the overall cost.

Why is my refinance quote different from an advertised rate?
An advertisement may describe a rate available only under stated conditions. A personalized quote can reflect the loan type, requested amount, term, and details assessed by the lender. Check the written offer for the rate and conditions that apply to you.

Does a lower monthly payment mean I pay less overall?
Not necessarily. Extending repayment can reduce each scheduled payment but increase the total number of payments and possibly total interest. Compare the full term and fees as well as the monthly amount.

Does this calculator include refinance fees?
No. It estimates principal-and-interest payments from the amount, APR, and term. Add or account for fees separately using the lender’s documents; do not assume a quoted payment includes costs that are not listed.
