Eastern Restaurant Supply sells a set of mixing bowls with a list price of $200. Suzi’s
Muffins qualifies for the series of discounts: 25%, 20%, 10%. Compute the net price
using the discount method.

COMPLEMENT METHOD SHORTCUT
When using complement rates, the buyer may not need to know all of the intermediate
prices. If not, an efficient shortcut is to multiply the list price by all of the complement
rates successively.
EXAMPLE E
Repeat example D, using the shortcut. The list price is $200, and the discounts are 25%,
20%, and 10%. The complement rates are 75%, 80%, and 90%.
Net price 5 $200 3 0.75 3 0.80 3 0.90 5 $108
Note: Remember that there should be no rounding until you reach the final net price.
Then round it to the nearest cent.
a. A wholesaler offers a series of trade discounts: 30%, 25%, and 10%. Find each of the
discount amounts and the final net price on a $1,500 purchase.
First discount amount: $1,500 3 0.30 5 $450
Second discount amount: $1,500 2 $450 5 $1,050; $1,050 3 0.25 5 $262.50

Net price: $787.50 2 $78.75 5 $708.75
b. A series of trade discounts is 30%, 25%, and 10%. Find each of the complement rates, and
use the shortcut to calculate the final net price on a purchase of $1,500.
First complement rate: 100% 2 30% 5 70%
Second complement rate: 100% 2 25% 5 75%

CONCEPT CHECK 7.2
Suppose that an Eastern competitor, United Food Services, offers a single discount of
45% to Suzi’s Muffins. How does that rate compare to the series of discounts from
Eastern, 25%, 20%, and 10%? Suzi or her accountant could check by calculating the
equivalent single discount rate, which is the single discount rate that can be used in
place of two or more trade discount rates to determine the same discount amount.
The most efficient way to find the single discount rate that is equivalent to a series of
discounts is similar to the shortcut used in example E.
Chapter 7 Discounts 125
Compute the equivalent single
discount rate for a series of trade

Computing the Equivalent Single Discount Rate
7.3 Point out that the series of
discounts in example F is just slightly
better than the single discount of 45%.
If the series were 25%,20%,and 5%,
the single discount would be better.
to Compute the Equivalent Single Discount Rate
1. Compute the complement of each rate.
2. Multiply all the complement rates (as decimals), and then write the prod-
uct as a percent.
3. Subtract the product (Step 2) from 100% to get the equivalent single dis-
count rate.

COMPLETE ASSIGNMENT 7.1.
CONCEPT CHECK 7.3
When a seller sends merchandise to a buyer, the seller usually wants to receive its pay-
ment quickly, and some buyers often try to delay payment as long as possible. Sellers can
encourage early payment by offering a cash discount; they can discourage late payment
by assessing an extra interest payment; or they can do both. These stipulations are called
the terms of payment, or simply the terms. The terms describe details about cash dis-
counts and/or penalty periods.
After shipping merchandise to a buyer, the seller usually sends a document called an
invoice, requesting payment. An invoice lists each item, its cost (including packaging and
freight), and the total cost. The invoice also states the terms of payment. The amount the
buyer pays is called the remittance. The net purchase amount is the price of the mer-
chandise actually purchased, including allowances for returns and excluding handling
and other costs.

Learning Objective
Compute cash discounts and
remittance amounts for fully paid
invoices.
7.4 For large purchases,the amount of
the cash discount may be large enough
that the buyer will consider borrowing
money for a few days just to get the
discount.(See Chapter 15.)
7.5 The term net purchase amount isn’t
really needed here,but it will be useful
when returned merchandise and/or
freight charges are considered later in
the chapter.

Figure 7-1 shows an invoice from National Automotive Supply, which sold car wax to
Broadway Motors for $528. The wax will be shipped via UPS, and National will pay for
the shipping. The invoice lists terms of 2/10, n/30. The invoice date, or the beginning of
the discount period, is May 23.

The expression 2/10, n/30 means that Broadway Motors can get a 2% discount if it
pays the full invoice within 10 days of the invoice date. Ten days after May 23 is June 2,
which is called the discount date. The 10-day period between May 23 and June 2 is
called the discount period. The n/30 is short for net 30, which means that if Broadway
Motors does not pay within 30 days, National will charge an interest penalty. Thirty days
after May 23 is June 22, which is called the due date. (See Figure 7-2.)

All companies do not use exactly the same notation for writing their terms; 2/10,
n/30 is also written as 2/10, net 30 or as 2-10, n-30. Likewise, there can be more than one
discount rate and discount period. For example 2/5, 1/15, n/30 means that the seller gets
a 2% discount by paying within 5 days, gets a 1% discount by paying within 6 and 15 days,
and must pay a penalty after 30 days. To teach different notations, this book will present
cash discounts in various ways.
RETURNED MERCHANDISE AND FREIGHT CHARGES
The seller gives a discount only on merchandise that is actually purchased—the net pur-
chases. For example, there is no discount on returned items. Likewise, there is no dis-
count on charges from a third party, such as freight.
to Compute the Remittance When There Are Merchandise
Returns and/or Freight Charges
1. Net purchase 5 Invoice amount 2 Merchandise returns 2 Freight
2. Cash discount 5 Discount rate 3 Net purchase
3. Cost of merchandise 5 Net purchase 2 Cash discount
4. Remittance 5 Cost of merchandise 1 Freight, if any

National Automotive Supply sells merchandise to Broadway Motors. The invoice amount
is $510, which includes $30 in freight charges. The invoice date is August 13, and the
terms are 2/10, n/30. Broadway Motors returns $200 worth of merchandise and pays the
rest of the invoice before the discount date. Compute the cash discount and the remit-
tance. Also, determine the discount date and due date.

Step 3 and calculate the remittance directly:
Remittance 5 $280.00 2 $5.60 1 $30.00 5 $304.40
There is also a complement method for cash discounts. However, it is not used
universally because some businesses want to know the amount of the cash discount
before deciding whether to pay the invoice early. In the complement method for cash
discounts, only Steps 2 and 3 change.
to Compute the Remittance with the Complement Method
1. Net purchase 5 Invoice amount 2 Merchandise returns 2 Freight
2. Complement rate 5 100% 2 Cash discount rate
3. Cost of merchandise 5 Net purchase 3 Complement rate
4. Remittance 5 Cost of merchandise 1 Freight, if any

Sometimes a buyer would like to take advantage of a cash discount but can afford to pay
only part of the invoice within the discount period. If the seller allows discounts for par-
tial payment, the invoice will be reduced by the amount paid (remittance) plus the
amount of the discount. The total of the amount paid plus the amount of cash discount
is called the amount credited to the buyer’s account. To compute the amount credited,
you need to know the complement rate: 100% 2 Discount rate.

Learning Objective
to Compute the Unpaid Balance
1. Compute the complement of the discount rate (100% 2 Discount rate).
2. Compute the amount credited by dividing the dollar amount paid
(remittance) by the complement rate.
3. Compute the unpaid balance by subtracting the amount credited
(Step 2) from the invoice amount.

EXAMPLE J
Larry Eickworth operates a shop called Space Savers, a do-it-yourself center for closet
and storage materials. Larry buys shelving supplies with an invoice price of $484 and
terms of 2/10, net 60. Within the 10-day discount period, he sends in a check for $300.
With a discount for the partial payment, how much credit should Larry receive, and
what will be his new unpaid balance?
Complement rate 5 100% 2 2% 5 98%
Amount credited 5 $300 4 0.98 5 $306.1224, or $306.12
Unpaid balance 5 $484.00 2 $306.12 5 $177.88
STEP 3
STEP 2
STEP 1
Note that, in example J, Larry receives $1.00 credit for every $0.98 paid. In other
words, the $300 actually remitted is 98% of the total amount credited. We can check this
result with multiplication:
Cash discount 5 0.02 3 $306.12 5 $6.1224, or $6.12
Remittance 5 $306.12 2 $6.12 5 $300.00
A slightly different situation, which arises less frequently, is when a buyer decides in
advance the total amount that he or she wants to have credited to the account. This
problem is exactly like the original cash discount problems.
EXAMPLE K
Larry Eickworth buys $484 worth of shelving materials for use in his closet and storage
shop. The terms are 2/10, net 60. Larry wants to pay enough within the 10-day discount
period to reduce his unpaid balance by exactly $300. What amount should he remit to
the seller? What will be his new unpaid balance?
Cash discount 5 2% 3 $300 5 $6
Remittance 5 $300 2 $6 5 $294
Unpaid balance 5 $484 2 $300 5 $184
