FAQ
What formula is used?
The standard amortizing loan formula: M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is principal, r is the periodic interest rate, and n is the number of payments.
Does this include fees or insurance?
No, this calculates principal and interest only. Add any fees or insurance separately for a full picture of your payment.
