Auto Loan Cash-Out Refinance Calculator and Guide

An auto loan cash-out refinance replaces your current car loan with a new, larger loan and gives you some of the difference in cash. This calculator estimates a level monthly payment and total interest for a loan amount, APR, and term; use the proposed new loan amount, which may include the cash you want to receive.

Formula

The calculator estimates a fixed monthly payment using the standard amortizing-loan formula:

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

• P is the new loan principal, in dollars. It is the full amount borrowed, not just the cash paid to you.
• r is the monthly interest rate, calculated as APR ÷ 1,200. APR is entered as a yearly percentage.
• n is the number of monthly payments, calculated as years × 12.

Total interest is estimated as the displayed monthly payment multiplied by the number of payments, minus the principal: interest = monthly payment × n − P. The payment is rounded to the nearest cent before total interest is calculated.

Worked Example

Using the calculator’s default values—$20,000 principal, 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 formula: $20,000 × 0.0066667 ÷ [1 − (1.0066667)⁻⁶⁰] = $405.53 per month, rounded to cents.
4. Calculate total interest using that rounded payment: $405.53 × 60 − $20,000 = $4,331.80.

Assumptions

• The interest rate stays fixed for the full term.
• Payments are made monthly, with the first payment one month after the loan begins.
• Interest is compounded monthly using APR ÷ 12.
• The estimate excludes fees, taxes, insurance, add-on products, and any other charges unless they are included in the loan amount you enter.

What Cash-Out Auto Refinancing Means

In a cash-out refinance, a new lender or loan arrangement pays off the existing auto loan, then lends a larger principal amount. If the new loan exceeds the payoff amount, eligible costs, and other amounts rolled into the transaction, the remaining funds may be paid to the borrower. The car generally continues to secure the debt, so missed payments can have consequences for the vehicle under the loan contract.

For example, suppose a lender’s payoff figure is $12,000 and a borrower seeks $3,000 in cash. Before any fees or other amounts, the replacement loan would need to cover $15,000. That is only an illustration of the arithmetic: whether a lender offers that amount, and how much cash is actually disbursed, depends on its terms and the vehicle and borrower details.

The calculator does not determine the cash proceeds. Entering $20,000 estimates payments on a $20,000 loan; it does not mean the borrower receives $20,000 in cash. To estimate the proposed loan principal, add the payoff amount, requested cash, and any costs being financed, then use the actual figures supplied for the transaction.

How the Transaction Works

The new loan’s principal is commonly based on the current loan payoff rather than the balance shown on an older statement. Payoff amounts can include interest accrued since the last payment and may differ by date. Ask for a dated payoff quote and confirm how long it remains valid.

A typical process to understand and compare a proposal is:

1. Get the current loan payoff amount and check the vehicle’s title and loan information.
2. Request the proposed new principal, APR, term, payment schedule, itemized costs, and expected cash disbursement in writing.
3. Use the proposed principal, APR, and term in the calculator to estimate payment and interest.
4. Compare the full repayment amounts and contract terms—not only the monthly payment—and verify how the existing loan will be paid off.

These are information-gathering steps, not a recommendation to refinance. The lender’s written disclosure and contract control the transaction figures.

Costs, Trade-Offs, and Common Problems

A lower monthly payment does not by itself show that a refinance costs less. Extending the repayment period can reduce the scheduled payment while increasing the time interest accrues. A larger principal also means interest is calculated on more borrowed money. Compare total payments over the full proposed term and account for any costs included in the new balance.

• Vehicle value and loan balance: If the amount owed is high relative to the car’s value, a lender may limit the amount it will refinance. The calculator cannot assess vehicle value or approval.
• Negative equity: If the payoff exceeds the vehicle’s value, carrying that shortfall into another loan can increase the debt secured by the car.
• Fees and add-ons: Application, title, or other transaction costs may affect the amount financed or cash received. Request an itemized figure; this calculator does not estimate these charges.
• Term and vehicle age: Lenders set their own eligibility and contract terms. A longer term can also mean the loan lasts longer relative to the car’s useful life.
• Payment timing: A payoff and new-loan funding may not occur on the same day. Confirm who is responsible for payments while the old loan is being closed, and check that it is paid off.

Do not assume that cash-out refinancing is the same as taking cash from a car’s value without borrowing. The cash is generally part of a new debt obligation, and the vehicle remains collateral under the contract.

Using the Estimate Carefully

Use the APR and term shown in the actual proposed disclosure, rather than an assumed market figure. APR and interest rate can differ in how they reflect credit costs; this calculator treats the entered APR as the annual rate for a simplified monthly-payment calculation. It does not model lender-specific fees, daily interest, variable rates, irregular payment dates, or payment rounding practices beyond rounding the estimated payment to cents.

Small differences from a lender’s quote can result from the funding date, the exact payoff, fee treatment, or a different calculation method. The estimate also does not assess whether a proposed loan is available to a particular borrower. Get the real rate, costs, cash amount, and repayment schedule directly from the lender.

Frequently Asked Questions

Can I get cash from refinancing my car loan?
Some lenders offer cash-out auto refinancing, but availability and eligible amounts depend on lender terms and borrower and vehicle details. The cash is generally borrowed money added to the replacement loan.

How much cash can I get from an auto refinance?
There is no amount this calculator can determine. It depends on the lender’s maximum loan amount, payoff, vehicle valuation, costs, and other requirements. Request a written estimate of both the new principal and net cash disbursement.

Does cash-out refinancing lower my car payment?
It may produce a different payment, but the result depends on the new principal, APR, and term. A longer term can lower a monthly payment while increasing total interest, so compare the complete repayment schedule.

Is cash-out refinancing the same as a car title loan?
No. Cash-out refinancing replaces an existing auto loan with a new loan. A title loan is a different type of borrowing secured by a vehicle title; terms and risks differ. Read the specific contract rather than treating the products as interchangeable.

Does the calculator show how much cash I will receive?
No. It estimates payment and interest for the loan principal entered. Net cash depends on the payoff, financed costs, and the lender’s disbursement calculation, which must be confirmed in its documents.

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