8.1 Markup and Markdown A very large part of the business conducted in this world is a matter of buying things and then turning around and selling them to someone else at a profit. The price a business pays for an item is called the wholesale price or cost. The price a business sells the item for is known as a retail price.

8.1 Markup and Markdown One common method used for setting the selling price for an item is markup based on cost. To determine a price with this method, we simply take the cost of the item and add on a pre-determined percent of the item’s cost.

8.1 Markup and Markdown FORMULA 8.1.1 Markup Based on Cost
P = C(1 + r) where P represents the SELLING PRICE C represents the COST and r represents the PERCENT MARKUP

Example 8.1.1 Problem Solution 8.1 Markup and Markdown
An auto mechanic charges a 40% markup based on cost for parts. What would the price be for an air filter that cost him \$14.95? What is the dollar amount of his markup on this item? Solution P = C(1 + r) P = \$14.95(1 + 40%) = \$20.93 Markup = \$ \$14.95 = \$5.98

8.1 Markup and Markdown Example 8.1.2 Problem
Hegel’s Bagels and Vienna Coffeehouse sells souvenir coffee mugs for \$ The markup based on cost is 65%. Find (a) the cost of each mug and (b) the dollar amount of the markup. Solution P = C(1 + r) P = \$7.95(1 + 65%) = \$4.82 Markup = \$ \$4.82 = \$3.13

8.1 Markup and Markdown Example 8.1.3 Problem
An electronics retailer offers a computer for sale for \$1,000. The retailer’s cost is \$700. What is the markup percent? Solution P = C(1 + r) \$1,000 = \$700(1 + r) r = = 42.86%

8.1 Markup and Markdown We are all familiar with the idea of prices being marked down as part of a sale or some other promotion, for example. To calculate a marked-down price, we simply apply the percent the price is to be marked down to the original price, and then subtract.

8.1 Markup and Markdown FORMULA 8.1.2 Markdown MP = OP(1 – d) where
MP represents the MARKED-DOWN PRICE OP represents the ORIGINAL PRICE d represents the PERCENT MARKDOWN

8.1 Markup and Markdown Example 8.1.4 Problem
At its Presidents’ Day Sale, a furniture store is offering 15% off everything in the store. What would the sale price be for a sofa that normally sells for \$1,279.95? What is the dollar amount of the markdown? Solution MP = OP(1 – d) MP = \$1,279.95(1 – 15%) = \$1,087.96

8.1 Markup and Markdown Example 8.1.5 Problem
Hal’s Hardware Haven is having a going-out-of-business sale. According to its ad, everything in the store is marked down 40%. If a set of patio lights is offered at a marked-down price of \$29.97, what was the original price? How much of a dollar savings is this versus the original price? Solution MP = OP(1 – d) \$29.97 = OP(1 – 40%) OP = \$49.95

Example 8.1.6 Problem Solution 8.1 Markup and Markdown
At the end of the summer, a backyard play set that usually sells for \$ is marked down to \$450. What is the markdown percent? Solution MP = OP(1 – d) \$450 = \$599.95(1 – d) d = = 24.99%

8.1 Markup and Markdown Example 8.1.7 Problem
Gemma’s Gemstone Gewelry bought a necklace for \$375. In the store, Gemma marked up this price by 20%. Several months later, when the necklace still had not sold, she decided to mark down the price by 20%. What was the marked down price? Solution Markup P = C(1 + r) P = \$375(1 + 20%) = \$450 Markdown MP = OP(1 – d) MP = \$450(1 – 20%) = \$360

8.1 Markup and Markdown Example 8.1.8 Problem
If prices are calculated with a 35% markup based on cost, what is the percent that those prices should be marked down to get back to their original cost? Solution We don’t know what sort of things we are pricing here, much less the dollar amounts of those things. However, since we are working with percents, the actual dollar amounts don’t really matter. We choose a convenient cost of \$100. P = C(1 + r) P = \$100(1 + 35%) P = \$135 MP = OP(1 – d) \$100 = \$135(1 – d) d = 25.93%

Problem 1 Wal-Mart charges \$2.35 for a carton of eggs. If the price is based on a 45% markup based on cost, how much did they pay the chicken farmer? CHECK YOUR ANSWER

Solution 1 Wal-Mart charges \$2.35 for a carton of eggs. If the price is based on a 45% markup based on cost, how much did they pay the chicken farmer? P = C(1 + r) \$2.35 = C(1 + 45%) \$2.35 = C x 1.45 C = \$1.62 BACK TO GAME BOARD

Problem 2 You bought an evening gown for \$35, what a deal! If the markdown percent was 70%, what was the original price? CHECK YOUR ANSWER

Solution 2 You bought an evening gown for \$35, what a deal! If the markdown percent was 70%, what was the original price? \$35 = OP(1 – 70%) \$35 = OP x 0.30 OP = \$116.67 BACK TO GAME BOARD

8.2 Profit Margin The gross profit on an item is the difference between what the item cost and what it sold for. Of course, the business of buying and selling is not that simple. Every store has to take on plenty of other overhead expenses such as rent, utilities, salaries, finance costs, advertising expenses, etc. Gross profit does not account for those. The net profit, on the other hand, is the profit made after taking into account all of the expenses of doing business. The profit margin is the profit expressed as a percent of the selling price.

8.2 Profit Margin Example 8.2.1 Problem Solution
Sally’s Fashion Paradise sells a dress that cost \$45 for \$65. Find the gross profit margin from this sale. Solution Gross Profit = \$65 -- \$45 = \$20 Gross Profit Margin = \$20/\$65 = = 30.77% Example 8.22 Sally’s Fashion Paradise sells women’s purses, pricing them with a 35% gross profit margin. If a purse is priced at \$72, what is the gross profit in that price? Gross Profit = 35% x \$72 = \$25.20

8.2 Profit Margin Example 8.2.3 Problem
Last year, sales at Sally’s Fashion Paradise totaled \$219,540. The cost of the items sold was \$147,470. What was the overall gross profit margin for the year? Solution Total Gross Profit = \$219, \$147,470 = \$72,070 Gross Profit Margin = \$72,070/\$219,540 = 32.83%

8.2 Profit Margin Example 8.2.4 Problem
Last year, Sally’s Fashion Paradise had overhead expenses totaling \$63,073. Find (a) expenses as a percent of sales and (b) the net profit margin. Solution \$63,073/\$219,540 = 28.73% Net Profit = \$72, \$63,073 = \$8,997 Net Profit Margin = \$8,997/\$219,540 = 4.10%

8.2 Profit Margin Example 8.2.5 Problem
Two years ago, Sally’s shop had sales totaling \$153,670. The cost of the goods sold was \$118,945, and her expenses totaled \$57,950. Find her overall (a) gross profit margin and (b) net profit margin for that year. Solution Gross Profit = \$153, \$118,945 = \$34,725 Gross Profit Margin = \$34,725/\$153,670 = 22.60% Net Profit = \$34, \$57,950 = -\$23,225 Net Profit Margin = -\$23,225/\$153,670 = %

8.2 Profit Margin Example 8.2.6 Problem Solution
In the year in which the dress sold for \$65, the total sales were \$219,540 and expenses were \$63,073. If expenses are allocated in proportion to sales, how much of the store’s expenses is attributable to that dress? Solution \$65/\$219,540 = % % x \$63,073 = \$18.67

8.2 Profit Margin Determining a price by using a target gross margin is called markup based on selling price, in contrast to markup based on cost. If we know the item’s cost, and if we know our markup percent based on cost, calculating the selling price is fairly straightforward. Profit margin, though, is a percent of the selling price. Obviously, we don’t know the selling price before we know the selling price!

8.2 Profit Margin FORMULA 8.2.1 Markup Based on Selling Price
C = SP(1 – r) where C represents the ITEM’S COST SP represents the SELLING PRICE and r represents the GROSS PROFIT MARGIN

8.2 Profit Margin Example 8.2.7 Problem Solution
Determine the selling price of an item costing \$45 in order to have a 35% gross profit margin. Solution C = SP(1 – r) \$45 = SP(1 – 35%) SP = \$69.23

8.2 Profit Margin Example 8.2.8 Problem C = SP(1 – r)
A cooperative market allows its members to place special orders for items they want to buy in bulk. The price the member pays is based on an 8% markup on selling price. Lynne ordered a case of protein bars, for which the market’s cost was \$ How much will she pay for this order? C = SP(1 – r) \$24.17 = SP(1 – 8%) SP = \$26.27

Merchants are normally free to set prices as they see fit, basing their pricing decisions on costs, profit targets, and competition. Still, many manufacturers do set suggested prices for their products. The suggested price for an item is known as a list price or manufacturer’s suggested retail price (MSRP). When a product has a list price, it is not uncommon for the item to be sold to a merchant on the basis of a discount to the list price. This is known as a trade discount.

Example 8.3.1 Problem Ampersand Computers bought 12 computers from the manufacturer. The list price is \$ and the manufacturer offered a 25% trade discount. How much did Ampersand pay for the computers? Solution \$ x 25% = \$671.25 12 x \$ = \$8,055.00

Example 8.3.2 Problem Samir’s House of Gadgets placed an order for 500 thingmies (list price \$4.95), 350 jimmamathings (list price \$8.95), and 800 hoozamawhatzits (list price \$17.99). The manufacturer offers a 27 ½% trade discount and includes shipping in its prices. Find the total due on the invoice for this order.

Example Cont. Solution Quantity Product # Description MSRP Total 500 Thingmies \$4.95 \$2,475.00 350 Jimmamathings \$8.95 \$3,132.50 800 Hoozamawhatzits \$17.99 \$14,392.00 Subtotal \$19,999.50 LESS: 27.5% discount (\$5,499.86) Net \$14,499.64 PLUS: Freight \$00.00 Total due

FORMULA 8.3.1 Trade Discounts NP = LP(1 – d) where NP represents the NET (DISCOUNTED) PRICE LP represents the LIST PRICE d represents the PERCENT DISCOUNT

Example 8.3.4 Problem What is the net cost for each jimmamathing in the previous example? Solution NP = LP(1 – d) NP = \$8.95(1 – 27.5%) NP = \$6.49

Example 8.3.5 Problem Samir realized that he forgot to order 400 doohickeys. He called the manufacturer and was given a price of \$2,652 for them. He did not ask for the list price but realizes that he needs to know it now. What is the list price for a doohickey? Solution \$2,652/400 = \$6.63 NP = LP(1 – d) \$6.63 = LP(1 – 27.5%) LP = \$9.14

Example 8.3.6 Problem A manufacturer offers a 30% trade discount. If the merchant sells items at a 10% discount to list, what is the gross profit margin? What is the markup based on cost? Solution We will use \$100 for convenience. The cost would be 70% x \$100 = \$70 The selling price would be 90% x \$100 = \$90 Gross Profit Margin C = SP(1 – r) \$70 = \$90(1 – r) r = 22.22% Markup Based on Cost \$90 = \$70(1 + r) r = 28.57%

Series discounts are multiple discounts to a price in succession. Sometimes, a manufacturer may offer multiple trade discounts. For example, a company might normally offer a 25% trade discount but during a special promotion or to match a competitor’s pricing, might offer an additional 15% discount. Despite appearances, it’s incorrect to conclude that success discounts of 25% and 15% are equivalent to a single discount of 40%. The single discount equivalent to a series of discounts is referred to as the single equivalent discount.

Example 8.3.7 Problem The list price for a herbal weight loss supplement is \$ The manufacturer normally offers a 25% trade discount, but during a special promotion it offers an additional 15% discount. Find the net price for this item. Solution 75% x \$39.95 = \$29.96 85% x \$29.96 = \$25.47 This could also be calculated more simply as (75%)(85%)(\$29.96) = \$25.47

Example 8.3.8 Problem Find the single equivalent discount for successive 25% and 15% discounts. Solution We will work from an assumed price of \$100. These discounts will reduce the price to 75% x 85% x \$100 = \$63.75 This is a total discount of \$ \$63.75 = \$36.25 As a percent of the list price, it’s \$36.25/\$100 = 36.25%

Example 8.3.9 Problem You work for a company that manufactures photovoltaic (solar) panels. Your company’s 70-watt panel lists for \$295 and you offer an 18% trade discount. A competing company lists its 70-watt panel for \$305 and offers a 25% trade discount. Ingraham Solar Systems, one of your main customers, tells you that it is considering switching to your competitor’s panels because of their lower cost. What additional discount do you need to offer to match your competitor’s price?

Example Cont. Solution You are selling your panels for 82% x \$295 = \$241.90 Your competitor is selling for 75% x \$305 = \$228.75 You would need to drop your current net price by \$ \$ = \$13.15 As a percent of \$241.90, it works out to \$13.15/\$ = 5.44%

A merchant may require customers to pay for their orders in advance, before the merchandise is shipped. It is not unusual, though, for a seller to sell items on credit, especially to customers with whom the seller has (or hopes to build) a good relationship. Even when credit is extended, the seller still wants to be paid promptly and late payments may incur interest charges. A cash discount is a discount offered for prompt payment. The period of time during which the cash discount is available is called the discount period.

Dating Method Discount Period Begins: Abbreviation Example Ordinary On the invoice date None. Assumed if not otherwise indicated. 2/10, n/30 End of Month At the end of the month following the invoice date EOM 2/10, n/30, EOM Proximo PROX 2/10, n/30, PROX Receipt of Goods When the buyer receives the merchandise ROG 2/10, n/30, ROG Postdated As of date indicated on the invoice AS OF 2/10, n/30, AS OF 3/7/08

Example Problem Ned’s Furniture Galaxy ordered a shipment of dining room sets. The invoice was dated March 14, 2007, and the order arrived on March 28, The manufacturer offers a 2 ½% cash discount for payment within 10 days. To take advantage of this discount, when must Ned make payment if the dating method is (a) ordinary dating, (b) end of month, (c) receipt of goods, or (d) postdated as of May 1, 2007?

Example Cont. Solution With ordinary dating, the clock starts ticking on the invoice date, March 14, so Ned must make the payment by March 24. With EOM dating, the clock starts ticking at the end of March, so Ned must pay by April 10. The furniture arrived on March 28 so Ned must pay by April 7. The discount period begins on May 1 so Ned must pay by May 11.

Problem 3 Alexa’s Antiques Boutique ordered several pieces from the dealer. The invoice was dated May 18, The dealer also offered a 2% cash discount for payment within 10 days. If Alexa wants to take an advantage of this offer, when and how much should she pay? CHECK YOUR ANSWER

Solution 3 Alexa’s Antiques Boutique ordered several pieces from the dealer for a total of \$25, The invoice was dated May 18, 2007, terms 2/10, n/30. If Alexa wants to take an advantage of this offer, when and how much should she pay? If not otherwise indicated, we assume that the dating method is ordinary, so discount period begins on the invoice date. The discount is 2% so Alexa would pay only 98% x \$25, = \$24, The last day to pay is 10 days after the invoice date, so it’s May 28, 2007. BACK TO GAME BOARD

8.4 Depreciation The dollar value of any thing that can be owned will change as time goes by. Some things, like real estate and collectibles, are expected to go up in value over time. We call that increase in something’s dollar value price appreciation. Other things, though, become less valuable with use and the passing of time. Computers and electronics become obsolete, used cars command lower prices, and business equipment becomes less valuable. The decline in something’s dollar value is called depreciation.

8.4 Depreciation Example 8.4.1 Problem Solution FV = PV(1 + i)n
According to a wine expert, the market price for a very rare bottle of Chateau la Plonque wine is \$3,650. In an interview in a wine trade publication, he states that he expects this particular bottle to appreciate at a 7% annual rate for the next 10 years. If his prediction turns out to be correct, what will the price be 10 years from now? Solution FV = PV(1 + i)n FV = \$3,650(1.07)10 FV = \$7,180.10

8.4 Depreciation Example 8.4.2 Problem Solution FV = PV(1 + i)n
Todd just bought a new car for \$23,407. According to an online used car pricing service, the value of this car will decline at a 15% annual rate. Assuming this is correct, what will the car’s value be in 5 years? Solution FV = PV(1 + i)n FV = \$23,407(0.85)5 FV = \$10,386

8.4 Depreciation When we calculate depreciation by assuming that each year’s depreciation is a set percent of a decreasing value, the amount of annual depreciation decreases with each passing year. For this reason, this is often referred to as declining balance depreciation. There is another very commonly used method for calculating depreciation, though. With straight-line depreciation, we assume that the price declines by the same dollar amount each year.

8.4 Depreciation Example 8.4.3 Problem
The Cotswold Real Estate Agency purchased a computer for \$2,000. The useful life of the computer is 5 years. The computer is assumed to have no salvage value. Find (a) the straight-line depreciation rate, (b) the depreciated value of the computer, and (c) the depreciated value after 7 years. Solution The computer will lose its full \$2,000 initial value in 5 years, and since it loses the same amount each year, the depreciation rate is \$2,000/5 = \$400 per year. If the computer’s value drops by \$400 per year for 3 years, that means it will be worth \$2,000 – 3(\$400) = \$800 at the end of the 3 years. Since the computer’s useful life is 5 years, from that time on it has a value of \$0.

8.4 Depreciation FORMULA 8.4.1 Straight-Line Depreciation Rate where
D represents the ANNUAL DEPRECIATION AMOUNT IV represents the INITIAL VALUE OF THE ITEM SV represents the SALVAGE (RESIDUAL) VALUE UL represents the USEFUL LIFE OF THE ITEM

DV = IV – D(n) when n < UL DV = 0 when n ≥ UL
8.4 Depreciation FORMULA 8.4.2 Straight-Line Depreciation DV = IV – D(n) when n < UL DV = 0 when n ≥ UL where DV represents the DEPRECIATED VALUE n represents the NUMBER OF YEARS THAT HAVE PASSED

8.4 Depreciation Example 8.4.4 Problem
Rework Example using D and DV formulas. Solution First, we find the annual depreciation amount. Then, we find the depreciated value after 3 years: DV = IV – D(n) = \$2, \$400(3) = \$800 Since n = 7 and UL = 5, and 7 > 5, we conclude that the value after 7 years is \$0.
