Frequently Asked Questions
How is my monthly loan payment calculated?
Monthly payment = P × [r(1+r)^n] / [(1+r)^n - 1], where P is principal, r is monthly interest rate, and n is total number of payments.
What is an amortization schedule?
An amortization schedule shows each monthly payment broken down into principal vs interest. Early payments are mostly interest; later payments are mostly principal.
How can I reduce total interest paid?
Making extra principal payments early reduces the loan balance faster, cutting total interest significantly. Even one extra payment per year can save thousands.
