What This Calculator Is
It is an extra car payment calculator for a fixed-rate loan. You enter your balance, interest rate, and regular payment, then add the extra you are considering.
What It Is For
Use it as a car loan calculator with extra payments to see which amount is worth it. Each extra dollar reduces the principal that interest is charged on, so small amounts can add up. Before making extra payments on a car loan, confirm how your lender applies them. Many apply a payment to fees and accrued interest first.
How to Use It
- Enter the current balance, APR, and monthly payment from your latest statement.
- Add an extra monthly amount, a one-time amount, or both. Rounding up is a simple option. For example, a $275 payment becomes $300.
- Compare the amounts in the table. Pick one that still leaves room for rent, food, and surprise costs.
- Tell your lender the extra is for principal only.
