; Here are some financial formulas that can be "read" into Mathomatic: ; Compound Interest Future Value Formula: f_v1 = p_v*(1+interest_rate)^n ; Annuity Formula: f_v2 = payment*(((1+interest_rate)^n-1)/interest_rate) ; Next we will combine these to produce that Amortized Loan Formula. pause ; Amortized Loan Formula (Mortgage Formula): f_v1 = f_v2 eliminate all payment ; solve for payment per period ; p_v = present value ; f_v = future value (maturity value) ; interest_rate = interest rate per period (1 = 100%) ; n = number of periods
