Question
Basic Answer
Step 1: Determine the periodic interest rate.
The annual interest rate is 6%, compounded annually. To find the monthly interest rate, we divide the annual rate by 12 (the number of months in a year):
Monthly interest rate = 6%/12 = 0.5% = 0.005
Step 2: Determine the number of periods.
The loan is amortized over 1 year, with monthly payments. Therefore, the number of payment periods is:
Number of periods = 1 year * 12 months/year = 12 months
Step 3: Calculate the periodic payment using the amortization formula.
The formula for calculating the periodic payment (PMT) of an amortized loan is:
PMT = P * (r * (1 + r)^n) / ((1 + r)^n – 1)
Where:
- P = Principal loan amount (Php 10,000)
- r = Periodic interest rate (0.005)
- n = Number of periods (12)
Let’s plug in the values:
PMT = 10000 * (0.005 * (1 + 0.005)^12) / ((1 + 0.005)^12 – 1)
PMT = 10000 * (0.005 * (1.005)^12) / ((1.005)^12 – 1)
PMT = 10000 * (0.005 * 1.0616778) / (1.0616778 – 1)
PMT = 10000 * 0.00530839 / 0.0616778
PMT ≈ 860.66
Final Answer
The periodic payment is approximately Php 860.66.
