To calculate the interest paid in year two, we need to first calculate the annual payment:
PV = $100,000
Annual interest rate = 8.5%
Number of years = 10
Using the formula for calculating an amortization payment, we get:
Annual payment = PV*(r*(1+r)^n) / ((1+r)^n - 1)
= $100,000*(0.085*(1+0.085)^10) / ((1+0.085)^10 - 1)
= $15,735.95
The interest paid in the second year is equal to the outstanding balance at the end of the first year multiplied by the annual interest rate.
Outstanding balance at the end of the first year = PV*(1+r)^(n-1) - annual payment*((1+r)^n - (1+r)^(n-1))/r
= $100,000*(1+0.085)^(1-1) - $15,735.95*((1+0.085)^10 - (1+0.085)^(1-1))/0.085
= $87,064.05
Interest paid in the second year = $87,064.05*0.085 = $7,927.
