Check it outHow loan payments work
A fixed-rate loan is amortized: each payment covers interest on the remaining balance plus a slice of principal. Early payments are mostly interest, later ones mostly principal. A longer term lowers the monthly payment but raises total interest — the trade-off this calculator makes obvious.
How itβs calculated
Monthly payment = P Γ r Γ· (1 β (1 + r)^βn), where r is the monthly rate and n the number of payments. Total interest = payment Γ n β principal.

Frequently asked questions
Does this include taxes, fees, or insurance?
No — it's principal and interest only. Add-ons like taxes, gap insurance, or origination fees are separate.
What rate should I use?
Use the APR you've been quoted. Your actual rate depends on credit score, term, and lender.
How can I pay less interest?
Choose a shorter term, make extra principal payments, or secure a lower rate by improving your credit.
