Simple Interest Loan Calculation

Simple interest calculation provides a straightforward way to determine the interest that accumulates on a loan over time. Typically, the formula for calculating simple interest is \( I = P \times r \times t \), where:

  • \( I \) is the interest earned or paid,
  • \( P \) is the principal amount (the initial amount of money),
  • \( r \) is the annual interest rate (decimal),
  • \( t \) is the time the money is borrowed for, in years.

Question 1: For a simple interest loan of $5000 at an interest rate of 7%, taken out on 08.19.14, and repaid on December 31 of the same year, the time \( t \) is approximately 0.33 years (or about 4 months). To find the interest:

I = P x r x t

I = 5000 x 0.07 x 0.33 ≈ 116.67

Thus, the total payment when the loan is paid off is the principal plus interest:

Total payment = Principal + Interest 

Total payment = 5000 + 116.67 ≈ 5116.67

So, the answers are:

a) Total payment is approximately $5116.67.

b) Interest paid is approximately $116.67.

Question 2: For a loan of $20,000 at 4% interest, the initial interest calculation for 45 days:

Using the same formula, \( t \) = 45/365 ≈ 0.1233 years,

the interest for 45 days is:

I = P x r x t

I = 20000 x 0.04 x 0.1233 ≈ 98.67

The new principal after paying off $8000 would be:

New Principal = Old Principal - Payment + Interest

New Principal = 20000 - 8000 + 98.67 ≈ 12098.67

For the second payment of $6000 after 30 days:

First, calculate the interest for the next 30 days:

I = 12098.67 x 0.04 x (30/365) ≈ 13.41

Once again adjust the principal:

New Principal = Previous Principal - Payment + Interest

New Principal = 12098.67 - 6000 + 13.41 ≈ 6098.08

Finally, when the loan comes due 45 days after this payment, we calculate again the interest for this period:

I = 6098.08 x 0.04 x (45/365) ≈ 6.06

Total amount owed = 6098.08 + 6.06 ≈ 6104.14

Thus, the answers are:

a) New principal after the first payment is approximately $12098.67.

b) New principal after the second payment is approximately $6098.08.

c) Total payment when the loan is due is approximately $6104.14.

Question 3: Writing a check for $500 to obtain $400 cash involves understanding the interest rate paid. The simple interest can be calculated using the amount over the principal. For 2 weeks, this period is \( t \) = 2/52 ≈ 0.0385 years.

The interest paid is:

I = 500 - 400 = 100

Now calculate the interest rate:

r = I / (P x t)

r = 100 / (400 x 0.0385) ≈ 6.52

So the interest rate paid is approximately 6.52%.

Same as Cash Deals

Same as cash deals allow consumers to purchase an item and pay for it later, often with no interest within a promotional period. However, if not paid in full by the end of this period, high interest is charged on the remaining balance, often retrospectively applied. These deals can be beneficial for consumers who can manage their cash flow and pay off the total before the interest kicks in. However, they can lead to financial pitfalls for those who may overlook payment deadlines or lack the discipline to pay on time.
