Step-by-step explanation:
The total loan payment = 300,000 * 10 Years = $3,000,000
There is a total loan cost formula solved for principal:
principal = (Total - Total * ((1 + rate)^ - # of years * 12) / (rate * # of years * 12)
The rate is the monthly loan rate = rate / 1,200 = 8 / 1,200 =
.0066666666...
principal =(3,000,000 - 3,000,000 * (1.0066666666)^-120) / (.0066666666 * 120)
<span>principal =(3,000,000 - (3,000,000 * 0.4505234643) / .8
