How to Use This Loan Calculator
Whether you are financing a car, consolidating debt, or taking out a personal loan, understanding your monthly payment is the first step. This calculator shows you the full picture: monthly cost, total interest, and how long it takes to pay off.
Understanding Your Results
- Monthly Payment — What you will pay each month. This is fixed for the entire term.
- Total Interest — The total cost of borrowing. On a $25,000 loan at 7.5% for 5 years, you pay over $5,000 in interest alone.
- Total Cost — Principal + Interest. The true price of the loan.
The Power of Extra Payments
Adding even a small amount to your monthly payment can save hundreds or thousands in interest. For example, adding $50/month extra on a $25,000 loan at 7.5% for 5 years saves roughly $400 in interest and pays off the loan 6 months early.
Try different extra payment amounts in the calculator above and watch how the payoff time shrinks.
Fixed Rate vs. Variable Rate Loans
This calculator assumes a fixed interest rate. With a fixed rate, your payment never changes. Variable-rate loans may start lower but can increase over time — they are riskier but sometimes cheaper if rates fall. For most personal loans and auto loans, fixed rates are the standard.
What Interest Rate Should You Expect?
- Excellent credit (720+): 5-8% for personal loans, 3-5% for auto loans
- Good credit (680-719): 8-13% for personal loans, 5-8% for auto loans
- Fair credit (640-679): 13-20% for personal loans, 8-15% for auto loans
- Poor credit (below 640): 20-36% — consider improving your credit first
