What is Bid Price? --Basic Concepts and Definitions

Marked Price refers to the price marked on a product, which is the selling price that a trader presents to consumers. Marked price is an important concept in business that directly affects consumers' purchasing decisions and the profitability of businesses.

Basic Concepts:

  • A price tag is an indication of the price of a good or service, usually displayed on a price label, advertisement or website.
  • The list price does not necessarily equal the final selling price as discounts, offers or other price adjustments may apply.
  • Factors such as cost, profit, market competition and consumer acceptance need to be taken into account in setting the tender price.

The importance of mark-ups in business:

  • Price Positioning: The price tag reflects the market positioning and brand image of the product.
  • Profit control: Reasonable price setting has a direct impact on the profitability of a company.
  • Competitive Strategies: Pricing is an important tool for companies to compete in the market.
  • Consumer psychology: Price tags affect consumers' perception of the value of goods and their willingness to buy.
Examples of price labelling in Hong Kong shops

Common forms of price labels found in Hong Kong shops

Examples of mark-ups in the Hong Kong business environment:

  • Café: Milk tea is priced at $18, but there may be set menu offers.
  • Convenience Store: Snacks labelled at $15, 10% discount for members
  • Department Store: Clothing marked at $299, may be sold at 50% off at the end of the season

Bid Price Formula - Mathematical Expression and Parameter Analysis

The basic formula for calculating the bid price is:

Bid = Cost × Bid Rate

maybe

Mark-up = Cost × (1 + Mark-up percentage)

Among them:

  • Cost: Purchase price or manufacturing cost of goods
  • Markup Rate: a multiple of cost, usually greater than 1
  • Percentage of increase: Percentage increase in cost basis

Tender Price Calculation Example

Example 1: Tea Diner Milk Tea

Cost: $8, Bid Rate: 150%

Tender = $8 × 1.5 = $12

Example 2: Clothing in a clothing shop

Cost: $120, plus price 60%

Tender = $120 × (1 + 60%) = $120 × 1.6 = $192

Example 3: Appliance Shop Products

Cost: $2000, Bid Rate: 125%

Tender = $2000 × 1.25 = $2500

Cost, Bid, Price Relationship - Complete Calculation System

Flow Chart of Cost Bid Price Selling Price Relationship

Core formula system

1. cost-to-tender

Bid = Cost × Bid Rate

2. tender price to selling price

Price = Tender Price × Discount Rate

maybe

Price = Tender Price × (1 - Discount Percentage)

3. Cost-to-sale (direct)

Price = Cost × Markup Rate × Discount Rate

4. Profit Calculation

Profit = Selling price - Cost

Profit margin = (selling price - cost) ÷ cost × 100%

Example of integrated calculation

Example:A clothing shop purchases a garment at a cost of $150.The shop owner plans to mark up the garment at 1,80% of the cost and then offer a 20% discount on the sale.

Request:(a) What is the tender price? (b) What is the selling price? (c) What are the profit and profit margin?

Solution:

(a) Mark-up = Cost × Mark-up rate = $150 × 1.8 = $270

(b) Selling price = tender price × discount rate = $270 × 0.8 = $216

(c) Profit = Selling price - Cost = $216 - $150 = $66

Profit margin = $66 ÷ $150 × 100% = 44%

Discount Calculation - Conversion of Tender Price to Selling Price

Discounts are a common promotional tool in business and understanding the calculation of discounts is essential to grasp the concept of mark-ups.

Representation of discounts:

  • Discount Rate:e.g. 20% (0.8), 10% (0.9) discounts
  • Discount Percentage:e.g. 20% off, 10% off
  • Discount Amount:e.g. minus $50, minus $100

Attention:

  • Chinese "20% off" means pay 80%, English "20% off" means reduce 20% (also pay 80%)
  • Continuous discounts need to be calculated gradually and cannot be added up directly.

Discount Calculation Example

Single Discount

Bid price: $200, 20% off sale

Price = $200 × 0.8 = $160

percentage discount

Price: $300, 30% off

Price = $300 × (1 - 30%) = $300 × 0.7 = $210

Continuous Discount

Markdown: $400, 10% off then 20% off

First time: $400 × 0.9 = $360

Second: $360 × 0.8 = $288

Or directly: $400 × 0.9 × 0.8 = $288

Fixed amount discount

Price tag: $500, minus $80

Price = $500 - $80 = $420

Profit Loss Calculation - Core Concepts in Business Mathematics

Profit

Profit generation when selling price is higher than cost

Profit = selling price - cost

Profitability = (selling price - cost) ÷ cost × 100%

Loss

Losses are incurred when the selling price is lower than the cost.

Loss = Cost - Selling Price

Loss ratio = (cost - selling price) ÷ cost × 100%

Break-even

When the selling price is equal to the cost, there is no gain or loss.

Break-even point: Price = Cost

Example of Profit and Loss Calculation

Profitability

Cost: $100, Price: $130

Profit = $130 - $100 = $30

Profitability = $30 ÷ $100 × 100% = 30%

Losses

Cost: $200, Price: $150

Loss = $200 - $150 = $50

Loss ratio = $50 ÷ $200 × 100% = 25%

Complications

Cost: $180, Bid: $270, 20% off sale!

Price = $270 × 0.8 = $216

Profit = $216 - $180 = $36

Profitability = $36 ÷ $180 × 100% = 20%

Bidding in DSE Maths - Exam Tips and Examples

Tabulation is an important part of the Percentage module of DSE Mathematics (Compulsory Part) and is a common question type in the examination.

Marked questions in the DSE exam:

  1. Given the cost and bid rate, find the bid price.
  2. Given a bid and a discount, find the selling price.
  3. Given the cost and selling price, find the profit margin.
  4. Complex calculations: involving multiple discounts or complex business situations
  5. Backward calculation: Given a selling price and a profit margin, find the cost or markup.

Key Steps to Solving Problems:

  1. Read the question carefully to identify the known conditions and the goal of the solution.
  2. Determine the formula to use: cost → markup → selling price → profit
  3. Pay attention to the way discounts are expressed (Chinese discount vs English % off)
  4. Step-by-step calculations to avoid leapfrogging
  5. Check the reasonableness of the answer
DSE Maths Exam Scene

DSE Style Example

Example 1:A bookstore bought a batch of books at $40 each and then marked them down to 1,50% of cost. Later, due to slow sales, it decides to sell them at 20% off the list price.

(a) Find the price tag for each book.

(b) Find the actual selling price of each book.

(c) Find the profit margin per book.

Answer:

(a) Mark-up = Cost × Mark-up rate = $40 × 1.5 = $60

(b) Selling price = tender price × discount rate = $60 × 0.8 = $48

(c) Profit = Selling price - Cost = $48 - $40 = $8

Profit margin = $8 ÷ $40 × 100% = 20%

Example 2:An appliance shop sells a television set for $3600 and receives a profit of 20%.

(a) Find the cost of the television set.

(b) If the original list price of the television set is 25% higher than the selling price, find the original list price.

Answer:

(a) Setting the cost at C, then: C × (1 + 20%) = $3600

C × 1.2 = $3600

C = $3600 ÷ 1.2 = $3000

(b) Tender = Selling price × (1 + 25%) = $3600 × 1.25 = $4500

Practical Application Scenarios - Hong Kong Business Environment Case Study

Tender pricing is widely used in various industries in Hong Kong and understanding these real-life scenarios will help to better understand the concept of tender pricing:

Retail Price Tagging Strategy

  • Convenience Store:Usually marked down to 140-160% of cost, such as 7-Eleven, Circle K
  • Supermarket:Adopting a thin profit and high sales strategy, the mark-up rate is usually 120-140%, such as Park'n Shop and Wellcome.
  • Department store:The price tag is higher, but there are always discounts, e.g. SOGO, Sogo.

Pricing Methods for the Catering Industry

  • Tea Café:3-4 times the cost of ingredients as mark-up, taking into account labour and rental costs
  • Fast food restaurants:Standardised pricing, typically 2.5-3 times cost
  • Fine dining:Considering the added value of environment, services, etc., the bidding rate can be as high as 5-8 times.

Online shop pricing tips

  • Compare pricing:Setting price tags with reference to other platforms
  • Psychological pricing:Use of $99, $199 and other prices to increase attractiveness
  • Dynamic pricing:Adjustment of tender price based on demand and inventory

Pricing Considerations in the Service Sector

  • Tutorial Club:Considering factors such as instructor qualifications, programme content, market competition, etc.
  • Beauty Salon:Pricing based on service items, product costs, technician skills, etc.
  • Repair service:Includes material costs, labour costs, technical difficulties, etc.

Hong Kong Practical Case: Pricing Analysis of a Hong Kong Style Cafe

Take the milk tea served in a typical Hong Kong cafe as an example:

  • Cost of materials:Tea, milk, sugar, etc. about $5
  • Other costs:Apportionment of labour, rent, utilities, etc. $3
  • Total cost:$8
  • Bid price:$18 (2.25 times cost)
  • Gross profit:$10, gross margin 125%

This pricing strategy takes into account the high rental and labour costs in Hong Kong while maintaining a reasonable profit margin.

Practice Questions and Explanations - Consolidate what you've learnt

Test your understanding of the calculation of the tender price with the following exercise:

Exercise 1:A clothing shop that imports a batch of T-shirts at $80 each plans to mark up the price at 175% of the cost and then offer a 10% discount.

(a) Find the price tag for each T-shirt.

(b) Find the selling price of each T-shirt.

(c) Find the profit and profit margin of each T-shirt.

Answer:

(a) Price = $80 × 1.75 = $140

(b) Price = $140 × 0.9 = $126

(c) Profit = $126 - $80 = $46, Margin = $46 ÷ $80 × 100% = 57.5%

Exercise 2:An appliance shop sells a washing machine for $2400 and makes a profit of 25%. The washing machine was originally priced at $3000.

(a) Find the cost of the washing machine.

(b) Find the actual discount rate.

(c) What will be the profit margin if the sale takes place at the original tender price?

Answer:

(a) Setting the cost at C, then C × 1.25 = $2400, so C = $1920

(b) Discount rate = $2400 ÷ $3000 = 0.8, i.e. 20% discount

(c) Profit margin at original tender price = ($3000 - $1920) ÷ $1920 × 100% = 56.25%

Exercise 3:A bookstore is holding a sale where all books are discounted 10% and then 20%. What is the final selling price of a book that was originally labelled $150? If the cost of the book is $90, what is the final profit margin?

Answer:

Final Price = $150 × 0.9 × 0.8 = $108

Profit = $108 - $90 = $18

Profit margin = $18 ÷ $90 × 100% = 20%
