APEX - $697.87

Answer: $697.87

The formula for the present value of an annuity payment, that is,

if you make n payments at interest rate i what will be the value of the

annuity after n payments. The formula assumes a monthly payment of 1.

A = (1 - (1 + i) ^-n) / i or what will the 1 payment be worth after n periods.

i =.05 / 12 the monthly interest rate

n = 360 the number of monthly payments

A = (1 - (1 + (.05/12)) ^-360) / (.05 / 12) = 186.28

Since each monthly payment of $1 = 186.28 after 30 years

what must be the monthly payment to have $130,000 in 30 years?

Payment = 130,000 / 186.28 = 697.87
