1. What is a Biweekly Auto Loan Calculator?

This calculator helps you understand how making biweekly payments (every two weeks) instead of monthly payments, along with extra payments, can reduce your loan term and total interest paid on an auto loan.

2. How Does the Calculator Work?

The calculator uses the following formulas:

\[ Interest_k = Balance_{k-1} \times r_{bi} \] \[ Principal_k = PMT_{bi} + extra - Interest_k \] \[ Balance_k = Balance_{k-1} - Principal_k \]

Where:

\( Interest_k \) — Interest portion of k-th payment
\( Balance_{k-1} \) — Remaining balance after previous payment
\( r_{bi} \) — Biweekly interest rate (annual rate ÷ 26)
\( PMT_{bi} \) — Regular biweekly payment amount
\( extra \) — Additional payment amount
\( Principal_k \) — Principal portion of k-th payment

3. Benefits of Extra Payments

Details: Making biweekly payments (26 half-payments per year instead of 12 monthly) plus extra payments can significantly reduce your loan term and total interest. Each extra payment goes entirely toward principal, reducing future interest calculations.

4. Using the Calculator

Tips: Enter your loan amount, interest rate, and term. Add any extra amount you plan to pay with each biweekly payment. The calculator will show your amortization schedule and savings.

5. Frequently Asked Questions (FAQ)

Q1: Why make biweekly instead of monthly payments?
A: Biweekly payments result in 26 half-payments per year (equivalent to 13 monthly payments), paying down principal faster and reducing interest.

Q2: How much can I save with extra payments?
A: Savings depend on your loan amount, rate, and extra payment amount. Even small extra payments can save thousands in interest.

Q3: Is there a penalty for extra payments?
A: Most auto loans don't have prepayment penalties, but check your loan agreement to be sure.

Q4: Should I refinance to get a biweekly payment schedule?
A: Not necessarily. You can make biweekly payments on a monthly loan by dividing your monthly payment by two and paying that amount every two weeks.

Q5: How accurate is this calculator?
A: It provides a close estimate, but your actual loan terms may vary slightly based on lender's specific calculation methods.
