Auto Refinance Break Even Calculation

Determining when refinancing your auto loan makes financial sense involves calculating the break-even point where the savings from the new loan equal the costs of refinancing. This guide explains how to perform this calculation, what factors affect the result, and when refinancing is truly beneficial.

What is a break-even point in auto refinancing?

The break-even point in auto refinancing is the number of months or miles driven after refinancing when the total savings from the new loan equal the total costs of refinancing. This calculation helps you determine whether refinancing will save you money in the long run.

Key components of the break-even calculation include:

The current loan balance
The new loan interest rate
Refinancing fees
Current interest rate on your existing loan
Projected monthly payments

Refinancing your auto loan can be a complex financial decision. Always consider your personal financial situation and consult with a financial advisor before making a decision.

How to calculate auto refinance break-even

The break-even point for auto refinancing can be calculated using the following formula:

Break-even Months = (Refinancing Fees) / (Monthly Savings)

Where Monthly Savings = (Current Monthly Payment - New Monthly Payment)

To calculate the break-even point:

Determine your current monthly payment and the new monthly payment with the refinanced loan
Calculate the monthly savings by subtracting the new monthly payment from the current monthly payment
Divide the total refinancing fees by the monthly savings to find the break-even point in months

For example, if you save $50 per month and have $500 in refinancing fees, your break-even point would be 10 months.

Factors affecting break-even time

Several factors can affect the break-even time for auto refinancing:

Interest rate difference: A larger difference between your current rate and the new rate will result in greater savings
Refinancing fees: Higher fees will increase the break-even time
Loan term: Shorter loan terms generally result in higher monthly payments and faster break-even points
Credit score: A higher credit score may qualify you for a lower interest rate, reducing the break-even time
Vehicle value: If your vehicle's value increases, refinancing may become more beneficial

Comparison of refinancing factors
Factor	Impact on Break-even Time
Lower interest rate	Reduces break-even time
Higher refinancing fees	Increases break-even time
Shorter loan term	Reduces break-even time
Higher credit score	Reduces break-even time

Example calculation

Let's walk through an example to illustrate how to calculate the auto refinance break-even point.

Scenario

Current loan balance: $20,000
Current interest rate: 8% APR
Current monthly payment: $380
New interest rate: 5% APR
New monthly payment: $300
Refinancing fees: $500

Calculation steps

Calculate monthly savings: $380 - $300 = $80
Calculate break-even months: $500 / $80 = 6.25 months

In this example, refinancing would pay for itself in about 6.25 months. This means you would start saving money after approximately 6.25 months of driving with the new loan.

When to refinance your auto loan

Refinancing your auto loan can be beneficial in several situations:

When interest rates have dropped significantly since you originally financed your vehicle
When you have good credit and can qualify for a lower interest rate
When you want to change the loan term to better match your financial situation
When you want to pay off your loan faster by making larger monthly payments

However, there are also situations where refinancing may not be beneficial:

When the break-even point is longer than the remaining loan term
When refinancing fees are high compared to the potential savings
When you don't plan to keep the vehicle for the full term of the new loan

Frequently asked questions
