Compute trade discounts.

Compute a series of trade discounts.

Compute the equivalent single discount rate for a series of trade

discounts.

Compute cash discounts and remittance amounts for fully paid

invoices.

Compute cash discounts and remittance amounts for partially paid

invoices.

Learning Objective

Businesses that sell products want to attract and keep customers who make repeated,

large-volume, more expensive purchases. Manufacturers, distributors, and wholesalers

frequently offer trade discou nts to buyers "in the trade," generally based on the volume

purchased. For example, Eastern Restaurant Supply gives a 40% discount to Regal Meals,

a local chain of 34 sidewalk sandwich carts that sell hot dogs and sausage sandwiches.

Another Eastern customer is Suzi Wilson, founder and owner of Suzi's Muffins. Suzi's

business is still small. She bakes her muffins between 11

P .M . and 2 A.M . in oven space that

she leases from a bakery. Eastern gives Suzi only a 25% discount because she doesn't do as

much business with Eastern as Regal Meals does. Eastern also sells to people who are not

"in the trade." These retail customers pay the regular list price, or full price without any

discount.

Large restaurant chains such as McDonald's and Burger King can go directly to the

manufacturer for most items or even do their own manufacturing. They can have items

manufactured to their exact specifications for a contracted price. They reduce their costs

by eliminating the distributors (the "middle men").

The two traditional methods for computing trade discounts are the discount

method and the complement method. You can use both methods to find the net price

that a distributor will charge the customer after the discount. The discou nt method is

useful when you want to know both the net price and the actual amount of the trade

discount. The complement method is used to find only the net price. It gets its name

because you use the complement rate, which is 100% minus the discount rate. Each

method has only two steps.

When one business sells merchandise to another business, the seller often offers two

types of discounts: trade discounts and cash discounts. Trade discounts affect the agreed-

upon selling price before the sale happens. Cash discounts affect the amount actually

paid after the transaction.

122 Part 2 Percentage Applications

Computing Trade Discounts

Learning Objective

Compute trade discounts.

7.1 Students may be more familiar

with cash discounts than with trade

discounts.Trade discounts are dis-

cussed first because the trade discount

is awarded by the seller before the sale,

to encourage the sale,whereas the

cash discount is awarded after the sale,

to encourage the payment.

7.2 Ask students if either discount

method might be more useful to busi-

nesses.If the buyer is comparing differ-

ent sellers,what really should interest

the buyer is the ultimate net price.It

doesn't make financial sense to base

the decision on a "larger discount"if

the net price isn't lower.Compare the

situation to that of retailers that have

"big sales"at various times throughout

the year.Some retailers that have repu-

tations for large discounts also have

high original prices.

to Compute Net Price with the Discount Method

1. Multiply the discount rate by the list price to get the discount a m ount:

Discount 5 Trade discount rate 3 List price

2. Subtract the discount from the list price to get the net price:

Net price 5 List price 2 Discount

STEPS

EXAMPLE A

Eastern Restaurant Supply sells a set of stainless steel trays to Suzi's Muffins. The list

price is $120, and Suzi qualifies for a 25% trade discount. Compute the net price using

the discount method.

Discount 5 0.25 3 $120 5 $30

Net price 5 $120 2 $30 5 $90

STEP 2

STEP 1

A distributor or manufacturer may give additional discounts to customers who actually

buy larger volumes. Suppose that Eastern Restaurant Supply gives all food preparation

businesses a 25% discount for being in the trade. However, if one business buys twice as

much from Eastern, it may be rewarded with additional discounts. For example, Suzi's

Muffins may receive its first discount of 25% automatically. Then, Suzi's gets an addi-

tional 20% discount if its accumulated purchases were between $10,000 and $25,000

during the previous year and another 10% if accumulated purchases were more than

$25,000 during the previous year. Therefore, Suzi's Muffins could have discounts of 25%,

20%, and 10%, called a series of discou nts.

Both the discount method and the complement method can be used to compute the

net price for a series of discounts. The two methods are the same as shown previously, ex-

cept that the steps are repeated for each discount in the series. For example, if there are

three discounts, repeat the steps three times. Apply the first discount rate to the list

price. For the second and third discounts, compute intermediate prices and then apply

the discount rates to them.

to Compute Net Price with the Complement Method

1. Subtract the discount rate fro m 100% to get the com plem ent rate:

2. Multiply the complement rate by the list price to get the net price:

Net price 5 Co m ple m ent rate 3 List price
