This calculator loops through the monthly payment equation unit it reaches a principal amount that drives a monthly payment in excess of the preferred monthly payment (MP). NOTE: this does not take into account that the first few years of a mortgage are largely interest payments, which is usually a tax deduction. If your monthly payment is based on your personal history of paying rent, which is NOT tax deductible, you will find that it is not a 1 to 1 comparison. One one hand, you will get tax money back, on the other, you will have expenses maintaining the property that the landlord used to cover.
This formula is commonly used for home mortgages and other simple debt. It is typically used in a way were the periods (t) are in years, and the number of payments per period (n) is 12 for the number of months. The word AMORTIZATION comes from the Middle English amortisen which means "to kill". In essence, this is the amount needed on a regular basis "to kill" a debt. The formula for amortized payment is:
`MP = (P * (r/12)) / (1- (1+(r/12))^(-12*N))`
