 Read the section below and complete the following activity.
Single-Payment Loans – A single-payment loan is a loan that you repay with one payment after a specified
period of time. A business may be short of funds and need to borrow money to meet its payroll or pay for
inventory and supplies. The business owner could sign a promissory note with its financial institution. A
promissory note is a written promise to pay a certain sum of money on a specific date in the future. The
maturity value of the loan is the total amount you must repay. It includes both the principal and the interest
owed. Remember that principal is the amount borrowed.
A loan’s term is the amount of time for which the loan is granted. For example, a single-payment loan may be
granted for a number of years, months, or days. When the term is a specific number of days, the lending agency
may calculate interest in one of two ways:
1. Ordinary interest is based on a 360-day year.
2. Exact interest is based on a 365-day year.
The following formulas are used:
Interest = Principal ∙ Rate ∙ Time
Ordinary Interest = Principal ∙ Rate ∙
Exact Interest = Principal ∙ Rate ∙
Time

Maturity Value = Principal + Interest
Example 1
Anita Sloane’s bank granted her a single-payment loan of $7,200 for 91 days to pay for new merchandise for her
candle shop. Determine the maturity value of the loan if the rate is (a) 6% ordinary interest or (b) 6% exact
interest.

Learning Goal: I can calculate the down payment and the amount

Video Instruction Available!
 Read the section below and complete the following activity.
Installment Loans – You could apply for an installment loan to finance the purchase of a new or used vehicle,
such as a car, truck, or motorcycle. You repay an installment loan in equal payments over a specified period
of time. Usually, when you purchase an item with an installment loan, you must make a down payment. The
down payment is a portion of the cash price of the item you are purchasing before financing the rest on credit.
It could be a dollar amount or a percent of the cash price. The amount financed is the portion of the cash price
that you owe after making the down payment. The formulas to calculate the amount financed are:
Amount Financed = Cash Price − Down Payment
Down Payment = Cash Price ∙ Percent
Example 1
Trudy Quintero is buying gym equipment for $1,399. She makes a $199 down payment and finances the
remainder. How much does she finance?
Find the amount financed.
Cash Price − Down Payment
$1,399 − $199 = $𝟏, 𝟐𝟎𝟎 amount financed
Trudy financed $𝟏, 𝟐𝟎𝟎.
Example 2 – Real-world Algebra Connection
Roslyn Clay purchased a previously owned piano for $1,140 using the store’s installment credit plan. She made a
20% down payment and financed the remaining amount. What amount did she finance?
Step 1:
Step 2:
Find the 20% down payment.
Down Payment = Cash Price ∙ Percent
Down Payment = $1,140 ∙ 20%
Down Payment = $1,140 ∙ 0.20
Down Payment = $𝟐𝟐𝟖
Find the amount financed.
Amount Financed = Cash Price − Down Payment

= $1,140 −

 Read the section below and complete the following activity (adapted from Lesson 8.3).
Installment Loans – When you obtain an installment loan, you must pay finance charges for the use of the
money. You repay the loan with equal monthly payments over a specified period of time. Part of each payment
pays the interest on the loan’s unpaid balance. The remaining part of the payment is used to reduce the balance
of the loan principal.
The amount of each monthly payment depends on the amount financed, the number of payments, and the
annual percentage rate. The annual percentage rate (APR) is an index showing the cost of borrowing money
on a yearly basis, expressed as a percent. You will need to refer to the Monthly Payment on a Simple Installment
Loan of $100 table listed below to calculate related amounts. You will also need to use the following formulas:
Monthly Payment =
Amount of Loan
$100
∙ Monthly Payment for a $100 Loan
Total Amount Repaid = Number of Payments ∙ Monthly Payment

 Read the section below and complete the following activity (adapted from Lesson 8.4).
Allocation of Payment on Installment Loans – As you learned in the last lesson, Lesson 8.3, an installment
loan is repaid in equal monthly payments. Part of each payment is allocated to pay the interest on the unpaid
balance of the loan, and the remaining part is used to reduce the balance. The interest is calculated each month
on the unpaid balance using the simple interest formula. The amount of principal that you owe decreases with
each monthly payment. The formulas follow:
Interest = Principal ∙ Rate ∙ Time
Payment to Principal = Monthly Payment − Interest
New Principal = Previous Principal − Payment to Principal
A repayment schedule shows the distribution of interest and principal over the life of a loan. The repayment
schedule below shows the interest and principal on an $1,800 installment loan for 6 months at 8%.
Example 1
Melinda and Xavier Garza obtained a loan for a used pickup truck. See the loan of $1,800 at 8% for 6 months in
the repayment schedule in the table above. She the calculation for the first payment. What are the (𝐚) interest,

monthly payment is $187.80. The balance of the loan after 20 payments is $2,849.08. What is the interest for the
first payment? What is the interest for the 21st payment? Why is the interest so much different for the two
payments?
Step 1:
Find the interest for the first payment.
Interest for First Payment = Principal ∙ Rate ∙ Time

Anton pays $𝟒𝟎. 𝟎𝟎 interest in the first payment.

Anton pays $𝟏𝟖. 𝟗𝟗 interest in the 𝟐𝟏st payment.

Lesson 8.5
Paying Off Installment Loans
Learning Goal: I can compute the final payment when paying off
an installment loan.

Video Instruction Available!
 Read the section below and complete the following activity.
Determining the Final Payment – When you have an installment loan, you pay interest on the unpaid
balance. You might have a simple interest installment loan for a car and sell the car before the end of the loan
term. If so, you pay only the previous balance plus the current month’s interest. This is known as the final
payment. Note that there may be a penalty for paying off a loan early.
One motive to pay off a loan before the end of the term is to pay less interest. The amount of interest saved
depends on the total payback minus the sum of the previous payments and the final payment. You will need to
use three formulas:
Interest = Principal ∙ Rate ∙ Time
Final Payment = Previous Balance + Current Month′ s Interest
Interest Saved = Total Payback − (Sum of Previous Payments + Final Payment)
Example 1
See the figure below for the first 3 months of the repayment schedule for Darlene and Hayden Grant’s home
repair loan of $1,800 at 12% interest for 6 months. What is the final payment if they pay the loan off with the
fourth payment?
Step 1:
Step 2:
Find the previous balance.
Read the repayment schedule above for the balance after the third payment. It is $913.70.
Find the interest for the fourth month.
Principal ∙ Rate ∙ Time
$913.70 ∙ 12% ∙
Step 3:

Example 2 – Real-world Algebra Connection
How much would the Grants in Example 1 save by paying off the loan early?
Find the interest saved.
Interest Saved = Total Payback − (Sum of Previous Paymetns + Final Payment)
(3 ∙ $310.50)
= (6 ∙ $310.50) − [
+ $922.84]
=
$1,863.00 − [

Determining the APR
Learning Goal: I can determine the annual percentage rate of a
loan using a table and a formula.

Video Instruction Available!
 Read the section below and complete the following activity.
Determining the APR – You should know that a lender who gives you an installment must tell you the annual
percentage rate (APR). If you know the number of monthly payments and the finance charge per $100 of the
amount financed, you can determine the loan’s APR. You can use a table such as the one below to find the
APR. With this information, you can compare the cost related to different loans. The full table can be found at
the end of this LEP on pages 36-37 and should be used to help you solve the homework problems.
Example 1
Paul Norris obtained a $1,500 installment loan to buy a racing bicycle. The finance charge is $146.25, and he will
repay the loan in 18 monthly payments. What is the APR?
Step 1:
Find the finance charge per $100.

Step 2: Find the APR. (Refer to the Annual Percentage Rate for Monthly Payment Plans table.)
