Price
  • List price
  • Discounts
  • Allowances
  • Payment period
  • Credit terms

33
Why is Pricing Important?
  • In a company with average economics,
  • 1 increase in volume 3.3 increase in profit
  • 1 increase in price 11.1 increase in profit
  • Improvements in price typically have 3-4 times
    the effect on profit as proportionate increases
    in volume.

Based on average of 2,463 companies
Marn Rosiello, 1992

Pricing Strategy
  • First/Central Strategy question
  • Higher than the competition?
  • Equal to the competition?
  • Lower than the competition?

37
Clarification of Terms
  • Cost what you/distributor/retailer paid for
    something
  • Price what you/distributor/retailer sell
    something for

Definitions
  • Variable Cost
  • Production/distribution costs required to place
    an additional unit of product in the hands of the
    customer.
  • Vary in direct proportion to sales volume
  • e.g., production materials, assembly work, sales
    commissions

43
Definitions
  • Fixed Cost
  • Production/distribution costs that stay the same
    regardless of changes in sales volume
  • Costs are fixed
  • e.g., RD, salaries, rent

44
Fixed or Variable Cost?
  • Materials
  • Physical plant
  • Plant labor
  • Supervisors in plant
  • Equipment
  • Marketing staff
  • Accounting staff
  • Finance staff
  • Salesperson salary
  • Salesperson commission
  • Advertising
  • Promotion
  • Coupons
  • Price cut

47
Definitions
  • Unit contribution
  • Price (revenue) less variable costs
  • Funds available to the seller after subtracting
    variable costs
  • Funds that can be used to contribute to fixed
    costs.
  • Selling Price/widget 75
  • Variable manufacturing cost/widget 25
  • Shipping/widget 2

  • Total variable costs/widget 31
  • Contribution/widget 44

Contribution Margin Contrib. Sales

49
Definitions
  • Contribution per widget 44
  • Have 44 to contribute to covering fixed costs,
    e.g.,
  • fixed manufacturing expenses
  • overheads
  • salaries
  • fixed marketing costs for the product

50
Break-Even
  • Revenue sufficient to cover
  • Variable costs
  • Fixed costs
  • No profits No losses

51
Breakeven Analysis
52
Break-Even Volume
  • How many widgets do you have to sell to break
    even? That is, What must our unit sales volume
    be to break even?
  • Total Fixed Costs/Unit Contribution
  • Unit Contribution 44
  • Fixed Costs 500,000/year
  • 500,000/44 11,364 widgets
  • Have to sell 11,364 widgets/year to break even

53
Exercise
  • How many Gizmos would you need to sell to break
    even in the following scenario?
  • Selling price/unit 10.00
  • Variable costs/unit 7.50
  • Fixed costs 9,000

54
Contribution and Market Size
  • Break-Even Point at 75 11, 363 widgets
  • We know that the market size is 50,000 widgets.
  • That would give us a market share of 22.7.
  • Then ask Does that make sense given what we
    know about the market?

55
Break-Even and Profit Goals
  • Can work a profit goal into the equation by
    adding the desired level of profit on to fixed
    costs.
  • Unit Volume to achieve profit goal
  • Fixed Costs Profit Goal
  • Contribution per unit
  • 500,000 100,000 13, 636 units
  • 44

56
Sensitivity Analysis
  • Methodically examining the financial impact of
    several sets of assumptions.

Six-Step Process for Setting Prices
  • Select the pricing objective
  • Determine customer demand
  • Estimate costs
  • Analyze competitors costs, prices, offers
  • Select a pricing method
  • Select final price

Kotler 9, Ch. 17
60
Overriding Goal
  • Achieve a commanding position in the market
    segment(s) served.

Not to compete in every market segment the
product might conceivably fit
Davidow, p. 116
61
Select the Pricing Objective
  • Maximize current profit
  • Maximize market skimming
  • Maximize sales growth (penetration)
  • Product/quality leadership

62
Estimate Demand
  • Analyze past prices, sales, other factors of
    similar products if available.
  • Conduct price experiments
  • Ask customers
  • Review factors affecting price elasticity and
    sensitivity

63
Customers are less price sensitive if
Pricing Sensitivity Factors
  • the product is highly innovative
  • the product is more distinctive than competition
  • there are few substitutes
  • product is used in conjunction with assets
    previously bought
  • product is assumed to have high quality

64
3. Estimate Costs
  • Variable Costs
  • Fixed Costs
  • Other Cost Concepts
  • Target Costing
  • Experience Curve

65
Target Costing
  • Determine the price customers are willing to pay
    for the product/service.
  • Determine what your costs would need to be to
    achieve that.
  • Design the product/service to meet that cost
    target.

76
Exercise coming
  • Think about your projects and one market
    segment.
  • What are some specific ways that you could
    determine how much your product is worth to that
    market segment?

77
Device Pricing vs. Whole Product Pricing
  • Value of any product to its market is strongly
    influenced by prices of competitive products.
  • Competitive devices are analyzed, but
    products are priced.
  • Product features have different values
  • Customer service
  • Warranties
  • Distribution channels (e.g., convenience)
  • The sum of the features makes up the product

Moore, p. 110 Davidow, p. 106
78
Perceived Value Pricing in Chemicals
79
Perceived Value Pricing in Chemicals
Note The Device is the chemicals. The
Product includes the device plus. . . .
80
Determining Perceived Value
  • What value is placed on the end result?
  • The cost of alternative solutions to the
    customer.
  • A function of
  • Prices of comparable (though not identical)
    products
  • The value (/-) of the products differences
    vs. the competitive offering
  • The value of the Whole Product

81
Economic Value Analysis
  • Identify the cost of the competitive product or
    process (i.e., the reference value)
  • Identify all the factors that differentiate the
    product.
  • Determine the value to the customer of these
    differentiating factors (i.e., the
    differentiation value)
  • Sum the reference value and the differentiation
    value to determine the total economic value.
