Loan Calculator for Personal & Auto Financing

Estimate monthly payments, total interest, and a clear amortization schedule for installment loans—instantly and privately.

How to use the loan calculator

Enter the amount you plan to borrow, the annual interest rate, and the loan term in either years or months. The calculator immediately shows your estimated monthly payment, how much interest you would pay over the life of the loan, and the total amount repaid if you make every scheduled payment on time.

Use this tool for personal loans, auto loans, or other fixed-rate installment products. Compare scenarios by changing the rate or term—for example, a shorter term usually raises the monthly payment but lowers total interest. The amortization table helps you see how quickly the balance declines and how much of each early payment goes to interest.

For home purchases, switch to the mortgage calculator to include taxes, insurance, and PMI in a full PITI estimate.

Understanding your loan results

Monthly payment is the fixed amount needed to fully amortize the loan over the selected term at the stated rate. Total interest is the cost of borrowing beyond the principal. Total amount paid equals principal plus interest across all payments in the schedule. These figures assume a fixed rate and level payment with no prepayments, late fees, or balloon balances.

Loan calculator FAQ

How is the monthly loan payment calculated?

We use the standard amortization formula based on loan amount, annual interest rate, and term in months. The payment stays level while the interest/principal split changes over time.

Can I switch between months and years?

Yes. Choose Years or Months as the term unit, then enter the length of the loan. A 5-year loan is the same as 60 months.

Does this include origination fees or compounding differences?

No. This estimate focuses on principal and interest only. Fees, dealer markups, and product-specific compounding can change the true APR and payment.
