Question: A mortgage has a contract rate of 4.25% compounded semi-annually. If the lender includes a $500 mortgage application fee for a $200,000, 5-year fixed term, what is the approximate APR (Annual Percentage Rate)?

Answer options:

• 4.30%
• 4.35%
• 4.39% ✅ 4.44%

Correct answer: 4.44%

Explanation: First, calculate the monthly payment based on the contract rate for a 5-year term. Assuming a 25-year amortization (standard assumption if not specified, but typically APR calculations use the specific term for the calculation). Let's assume a 25-year amortization for calculating the payment. Monthly payment for $200,000 at 4.25% semi-annually over 25 years is $1,073.49. Now, treat the $500 fee as an additional amount financed/paid up front. The 'true' amount borrowed effectively is $200,000 - the 'cost' that goes into the APR, which is 500 dollars. So, the lender effectively lends $199,500 but the borrower pays back based on $200,000. (Alternatively) The APR must be found by solving for 'i' where the PV of payments equals the principal MINUS initial fees. PV = $200,000 - $500 = $199,500. PMT = $1073.49, N = 5*12 = 60 months. Solving for 'i' (monthly equivalent of APR) on a financial calculator, yields approx. 0.003666. Convert this to annual (times 12) = 0.04399 = 4.40%. To convert to semi-annual equivalent (1 + 0.04399/12)^12 - 1 = (1 + i/2)^2 -1. Let me adjust my previous explanation, APR is the annual rate that makes the present value of all payments, less any lender fees, equal to the principal amount. So, Principal provided by lender (net of fees) = $200,000. Amount borrower needs to repay based on the APR calculation: PMT = $1,073.49, N = 5 years = 60 months. New PV for APR calculation is $200,000 minus the fee, so effective PV is $199,500. Using a financial calculator: PV=199500, PMT=1073.49, N=60. Solve for I/Y (monthly) = 0.3666%. This translates to an annual nominal rate of 0.3666% * 12 = 4.399%. To compare apples to apples (semi-annual compounding common in Canada) with a 25-year amortization the PMT for $200,000 at 4.25% semi-annual over 25 years is PMT = $1073.49. If only $199,500 was received, what rate would generate this payment? (PV=199500, FV=0, Pmt=1073.49, N=300). I/Y becomes 4.288% semi-annually. The question states what is the APR. The calculation is usually on the term of the mortgage, not the full amortization. So let's re-do for 5 years. Principal = $200,000, contract rate 4.25% semi-annual, 5-year term. P&I for 5 years. (1 + 0.0425/2)^2 - 1 = 4.301%. Now (1+0.04301)^(1/12) - 1 = 0.003507. PMT for $200,000 amortized over 5 years is $3700.32. Now factor in the fees. PV = $199,500. PMT = $3700.32, N = 60. Solve for I/Y. I/Y = 0.368% monthly. x 12 = 4.416%. Semi annual equivalent: (1 + 0.04416/12)^12 - 1 = (1+i/2)^2 - 1. So 4.44% is the closest, assuming the standard Canadian APR calculation method (where fees effectively reduce the amount borrowed but payments remain the same, on the term not the amortization).
