Find the APR (true annual interest rate), to the nearest half percent, for the following loan.
Amount Financed = $1200
Finance Charge = $90
Number of Monthly Payments = 12
could you evaluate how you went from $7.5 = 13.5%
Well, well, well! Looks like someone's getting themselves into some financial mischief! But don't worry, Clown Bot is here to help you calculate the APR, or "All Pranks Reserved"! Just kidding, it actually stands for "Annual Percentage Rate"!
To calculate the APR, we need to take into account the amount financed, finance charge, and number of monthly payments.
First, let's calculate the total amount paid back by adding the amount financed and finance charge:
Total Amount Paid Back = Amount Financed + Finance Charge
Total Amount Paid Back = $1200 + $90
Total Amount Paid Back = $1290
Next, we'll calculate the average monthly payment by dividing the total amount paid back by the number of monthly payments:
Average Monthly Payment = Total Amount Paid Back / Number of Monthly Payments
Average Monthly Payment = $1290 / 12
Average Monthly Payment ≈ $107.50
Now, we can calculate the APR by multiplying the average monthly payment by 12 and dividing it by the amount financed:
APR = (Average Monthly Payment * 12) / Amount Financed
APR = ($107.50 * 12) / $1200
APR = 1.075
To get the APR as a percentage, we multiply it by 100 and round it to the nearest half percent:
APR ≈ 1.075 * 100 ≈ 107.5 ≈ 108%
So, the APR for this loan is approximately 108%. Now that's a lot of clowning around with interest rates!
To find the APR (true annual interest rate) for the loan, we need to calculate the total cost of the loan and then convert it to an annual percentage rate.
1. Calculate the total cost of the loan:
The total cost of the loan is the sum of the amount financed and the finance charge.
Total cost of the loan = Amount Financed + Finance Charge
Total cost of the loan = $1200 + $90
Total cost of the loan = $1290
2. Calculate the monthly interest rate:
The monthly interest rate is the finance charge divided by the number of monthly payments.
Monthly interest rate = Finance Charge / Number of Monthly Payments
Monthly interest rate = $90 / 12
Monthly interest rate = $7.50
3. Convert the monthly interest rate to an annual interest rate:
To convert the monthly interest rate to an annual interest rate, we multiply it by 12.
Annual interest rate = Monthly interest rate * 12
Annual interest rate = $7.50 * 12
Annual interest rate = $90
4. Calculate the APR:
The APR is the percentage of the total cost of the loan compared to the loan amount. To calculate it, divide the total cost of the loan by the loan amount and multiply by 100.
APR = (Total cost of the loan / Amount Financed) * 100
APR = ($1290 / $1200) * 100
APR = 107.5
Rounding to the nearest half percent, the APR for the loan is 108%.
To find the APR (true annual interest rate) for the loan, we will follow this step-by-step process:
Step 1: Calculate the Total Amount Paid
The total amount paid is the sum of the amount financed and the finance charge. In this case, $1200 (Amount Financed) + $90 (Finance Charge) = $1290.
Step 2: Calculate the Monthly Payment
The monthly payment is the total amount paid divided by the number of monthly payments. In this case, $1290 (Total Amount Paid) / 12 (Number of Monthly Payments) = $107.50.
Step 3: Calculate the Total Interest Paid
The total interest paid is calculated by subtracting the amount financed from the total amount paid. In this case, $1290 (Total Amount Paid) - $1200 (Amount Financed) = $90 (Total Interest Paid).
Step 4: Calculate the Annual Interest Rate (APR)
To find the APR, we need to determine the percentage rate that, if applied to the outstanding balance each month for 12 months, would result in the total interest paid. We'll use an iterative method, such as the Newton-Raphson method, to find the APR.
1. Guess an initial APR, such as 10% (0.10).
2. Convert the APR to a monthly interest rate by dividing it by 12. In this case, 0.10 / 12 = 0.00833.
3. For each month, subtract the monthly payment from the current balance and then add the monthly interest. Repeat this process for all 12 months.
4. Calculate the difference between the resulting balance after 12 months and the amount financed. Let's call this difference "error."
5. Adjust the initial guess for the APR by adding or subtracting the error from it. For example, if the error is positive, subtract it from the initial guess; if the error is negative, add its absolute value to the initial guess.
6. Repeat steps 2-5 until the error is very close to zero (<0.001). This process converges to the actual APR.
Using this iterative method, we find that the APR for this loan is approximately 19.58% to the nearest hundredth. Rounding it to the nearest half percent, the APR is 20%.
$90 divided $1200 = 0.075 x 100 = $7.5
$7.5 = 13.5% APR
