To calculate the quarterly payment that the friend will make on the loan, we first need to break down the problem into a few clear steps:
-
Determine the future value of the loan after the initial delay.
- The initial loan amount is $2,005,600.
- The payments will start after 4 years, during which interest will accrue.
-
Calculate the total amount owed after the 4-year delay.
- The interest rate is 6.04% annually, which needs to be converted into a quarterly rate.
- The quarterly interest rate can be calculated as: \[ r = \frac{6.04%}{4} = \frac{0.0604}{4} = 0.0151 \]
- The number of compounding periods over the 4 years is: \[ n = 4 \text{ years} \times 4 \text{ quarters/year} = 16 \text{ quarters} \]
The future value can be calculated using the formula for compound interest: \[ FV = PV \times (1 + r)^n \] Substituting in the values: \[ FV = 2,005,600 \times (1 + 0.0151)^{16} \]
First, calculate \( (1 + 0.0151)^{16} \): \[ (1 + 0.0151)^{16} \approx 1.2725 \] Now substitute this back into the future value equation: \[ FV = 2,005,600 \times 1.2725 \approx 2,549,463.20 \]
-
Calculate the quarterly payments over the 11 years following the 4-year delay.
- There will be quarterly payments for 11 years, which means: \[ N = 11 \text{ years} \times 4 \text{ quarters/year} = 44 \text{ quarters} \]
The formula to calculate the payment (PMT) for an annuity is: \[ PMT = \frac{PV \times r}{1 - (1 + r)^{-N}} \] Given that \( PV = 2,549,463.20 \), \( r = 0.0151 \), and \( N = 44 \): \[ PMT = \frac{2,549,463.20 \times 0.0151}{1 - (1 + 0.0151)^{-44}} \]
First, calculate \( (1 + 0.0151)^{-44} \): \[ (1 + 0.0151)^{-44} \approx 0.4846 \] Now, substitute this value back into the PMT formula: \[ PMT = \frac{2,549,463.20 \times 0.0151}{1 - 0.4846} \] Compute \( 1 - 0.4846 \): \[ 1 - 0.4846 \approx 0.5154 \] Now compute PMT: \[ PMT = \frac{2,549,463.20 \times 0.0151}{0.5154} \approx \frac{38,566.25}{0.5154} \approx 74,798.67 \]
Thus, the quarterly payment will be approximately $74,798.67.
