Karen bought an apartment, with 480,000$ down-payment and 1,120,000$ loan. She needs to pay the loan in 15 years with equal repayment each month. The interest is 6% annually (for easy calculation, the interest is 0.5% monthly). i. How much should she pay every month? ii. For the first three months, list the principal and interest she needs to pay. (list for each month in the first three months)
i)
Loan = 1120000
i = 6%/12 = 0.5% per month
t = 15 * 12 = 180 months
Monthly loan payment = 1120000 * (A/P,0.5%,180)
= 1120000 * 0.005*((1 + 0.005)^180)/((1 + 0.005)^180-1)
= 1120000 * 0.005*((1.005)^180)/((1.005)^180-1)
= 1120000 * 0.008438568
= 9451.196 ~ 9451.20
