Illustrative amount; calculator limits are not lending eligibility limits.
Methodology and assumptions
Monthly payment = P × r ÷ [1 − (1 + r)^(−n)], where P is the loan amount, r is the annual rate divided by 1,200, and n is the number of monthly payments. At 0% APR, payment = P ÷ n. Total repaid = payment × n; total interest = total repaid − P.
This estimate treats your APR as a fixed nominal annual rate with monthly interest and payments at the end of each month. Fees, insurance, taxes, variable-rate changes, and extra payments are excluded unless a tool explicitly includes them. A disclosed APR can include fees and may differ from the contractual interest rate. Values are rounded for display only. Estimates are not lending offers.
Example: $10,000 at 15% for 36 months is approximately $346.65 per month, $2,479.52 in interest, and $12,479.52 repaid, assuming no fees.

How the personal loan calculator works
A personal loan is a fixed-rate installment loan. Your monthly payment is calculated with the standard amortization formula: it stays the same every month, but each payment splits between interest (calculated on the current balance) and principal. Early payments are mostly interest; later payments are mostly principal.
Two levers change your payment the most: the APR (rate) and the term (length). A longer term lowers the monthly payment but raises total interest. A shorter term does the opposite. The calculator's estimate is based on the inputs you provide — your real APR and offer come from our lending partners after a soft-pull rate check.
