A payment calculator finds your monthly loan payment based on loan amount, interest rate, and term — or works in reverse to show how large a loan you can afford given a specific monthly payment.
Fixed payment loans have the same payment every month. Variable payment loans can change based on interest rate adjustments. Fixed payments are easier to budget for and more common for personal and home loans.
A longer loan term means lower monthly payments but substantially more total interest. Always compare total cost, not just the monthly figure.
Each payment is split between interest and principal. In early months, most goes to interest. Over time, more goes toward the principal until the loan is fully repaid.
