FAQs
What inputs are needed for a loan payment estimate?
You need principal amount, annual interest rate, and repayment term in months.

No. The base loan calculator focuses on principal and interest only.
Why does a small rate change matter so much?
Interest compounds over time. Even modest APR changes can significantly affect total repayment.
