The monthly payment uses the standard loan formula: payment = amount × r × (1 + r)^n ÷ ((1 + r)^n − 1), where r is the annual rate ÷ 12 and n is the number of monthly payments. Sales tax, registration, insurance, mooring or storage, and upkeep are not included. The formula: M = P × r × (1 + r)^n ÷ ((1 + r)^n − 1). P is the amount borrowed, r is the monthly interest rate (annual rate ÷ 12) and n is the number of monthly payments.
