Bi Monthly Payment Calculator Auto

Reviewed by Calculator Editorial Team

When you take out an auto loan, you typically make monthly payments. However, some lenders offer bi-monthly payment options, which can provide financial benefits. This calculator helps you determine what your bi-monthly payments would be compared to standard monthly payments.

What is a bi-monthly payment?

A bi-monthly payment is a loan payment made every two months instead of every month. This means you'll make 6 payments in a year instead of 12. Bi-monthly payments are often used for auto loans and other types of loans where the lender offers this payment option.

The main advantage of bi-monthly payments is that they can help you pay off your loan faster than monthly payments. Since you're making more frequent payments, you'll be reducing the principal balance more quickly, which can save you money on interest over the life of the loan.

Bi-monthly payments are not the same as bi-weekly payments. Bi-weekly payments are made every two weeks, which is more frequent than bi-monthly payments.

How to calculate bi-monthly payments

Calculating bi-monthly payments involves understanding the loan terms and using a financial calculator or formula. The key factors to consider are:

  • Loan amount (principal)
  • Interest rate
  • Loan term (in years)

The formula for calculating the monthly payment is:

Monthly Payment = P * (r(1+r)^n) / ((1+r)^n - 1)

Where:

  • P = principal loan amount
  • r = monthly interest rate (annual rate divided by 12)
  • n = number of payments (loan term in years multiplied by 12)

For bi-monthly payments, you would calculate the monthly payment using the formula above, then multiply it by 2 to get the bi-monthly payment amount.

Bi-monthly vs. monthly payments

Comparing bi-monthly and monthly payments can help you decide which option is better for your financial situation. Here are some key differences:

Factor Bi-monthly payments Monthly payments
Payment frequency Every two months (6 payments/year) Every month (12 payments/year)
Payment amount Higher than monthly payments Lower than bi-monthly payments
Loan payoff time Faster than monthly payments Slower than bi-monthly payments
Interest cost Lower than monthly payments Higher than bi-monthly payments

Bi-monthly payments can be beneficial if you want to pay off your loan faster and reduce the total interest paid. However, the higher payment amount may not be feasible for everyone's budget.

Example calculation

Let's say you have an auto loan with the following terms:

  • Loan amount: $20,000
  • Interest rate: 5% annual
  • Loan term: 4 years

First, calculate the monthly payment using the formula:

Monthly Payment = $20,000 * (0.05/12 * (1 + 0.05/12)^48) / ((1 + 0.05/12)^48 - 1)

Monthly Payment ≈ $432.88

Then, multiply by 2 to get the bi-monthly payment amount:

Bi-monthly Payment = $432.88 * 2 = $865.76

In this example, the bi-monthly payment is $865.76, while the monthly payment would be $432.88. The bi-monthly option pays off the loan faster and reduces the total interest paid.
