Frequently Asked Questions
How is the monthly payment calculated?
Using the standard amortization formula: M = P[r(1+r)^n]/[(1+r)^n-1], where P is principal, r is monthly rate, n is number of months.
What is an amortization schedule?
A month-by-month table showing how each payment splits between principal reduction and interest. Early payments are mostly interest; later payments are mostly principal.
Can I calculate a balloon payment loan?
No — this tool calculates fully amortizing loans where the balance reaches zero at the end of the term.
