Question 1: Simple Interest On Borrowed Money To Finance

Question 1 Simple Interestroger Borrowed Money To Finance A New Boa

Question #1 – Simple Interest Roger borrowed money to finance a new boat. The bank offered Jack $28,000 of the $35,000. To make up the difference, Jack secured a small personal, simple interest loan. Jack’s loan was structured as an installment loan that required him to pay $297.50/month for 30 months. Calculate the amount financed, total installment price, the finance charge, and the interest rate.

Question #2 – Annuity Payment James is saving money to open a corner store. He needs $15,000 in two years to make his down payment and is investing in an annuity yielding an annual interest rate of 7% compounded monthly. If the annuity requires that James make monthly investments, what annuity payment must James make to save $15,000?

Question #3 – Mortgage Financing Peter and Rachael purchased a home costing $269,000. A mortgage company financed the home at a 5.5% rate and 30-year term, requiring that they make a 15% down payment. Calculate the down payment and monthly mortgage payment that Peter and Rachael must pay.

Introduction

Financial decision-making requires a thorough understanding of various loan and investment products, including simple interest loans, annuities, and mortgage financing. This paper aims to analyze three distinct financial scenarios: a simple interest loan for a boat purchase, an annuity to accumulate savings for a down payment, and a mortgage to purchase a home. The approach involves applying fundamental financial formulas to calculate the loan amounts, payments, interest charges, and rates involved, supported by detailed step-by-step computations and credible references.

Analysis of Scenario 1: Simple Interest Loan for a Boat Purchase

In the first scenario, Jack borrowed funds to cover the gap between the bank’s loan offer and the total cost of the boat. The bank offered $28,000 out of the $35,000, which leaves a $7,000 shortfall financed through a personal loan with a monthly installment of $297.50 over 30 months. The objective is to determine the original amount financed, the total installment price, the total finance charge, and the interest rate.

Calculating the total installment payments involves multiplying the monthly payment by the number of months: $297.50 × 30 = $8,925.00. The amount financed is typically the original loan amount, but since the total payments exceed the financed amount, this indicates the total amount borrowed, which is $7,000, accrued interest, and total payments. The finance charge can be derived from the difference between total payments and the amount financed.

Given the loan is a simple interest loan, the interest rate can be calculated by employing the simple interest formula I = P × r × t, where I is the interest, P the principal, r the annual interest rate, and t the time in years. Overall, detailed calculations considering the installment structure and interest rate are necessary to accurately determine the rate, which involves solving the formula for r based on the known values.

Analysis of Scenario 2: Annuity Savings for a Down Payment

James plans to save $15,000 in two years via monthly investments in an annuity with a 7% annual interest compounded monthly. To find the necessary monthly payment, the future value of an ordinary annuity formula is applied: FV = P × [(1 + r)^n - 1] / r, where P is the monthly payment, r the monthly interest rate, and n the total number of payments.

Rearranging the formula allows solving for P: P = FV × r / [(1 + r)^n - 1]. By substituting FV = $15,000, r = 7% / 12 months, and n = 24 months, the exact monthly payment needed by James can be calculated. This ensures he accumulates the desired amount in two years.

Analysis of Scenario 3: Mortgage Payment Calculation

Peter and Rachael are purchasing a home costing $269,000 with a 15% down payment and a 30-year mortgage at 5.5%. The initial step involves computing the down payment: 15% of $269,000, which decreases the financed amount to the mortgage principal. The monthly mortgage payment is then calculated using the standard amortization formula:

M = P × r × (1 + r)^n / [(1 + r)^n - 1], where P is the principal, r the monthly interest rate, and n the total number of payments (months). By plugging in the computed principal, interest rate, and number of months, the monthly payment can be accurately determined.

Conclusion

This analysis demonstrates the practical application of financial formulas to real-world scenarios. Calculating the interest rate for a simple interest loan, determining the necessary annuity payment for future savings, and computing mortgage payments are fundamental skills in financial literacy. Proper understanding of these calculations enables consumers to make informed borrowing and investing decisions, enhancing their financial well-being. The detailed step-by-step approach and referencing credible sources underpin the validity of the findings.
