Examples

Example 1: Clothing Reseller (Margin vs Markup)

Problem:

Buy a shirt for $50, sell for $80. What are margin and markup?

Solution:
  1. 1.Profit = 80 − 50 = 30
  2. 2.Margin = (30/80)×100% = 37.5%
  3. 3.Markup = (30/50)×100% = 60%
Result:Margin 37.5%, Markup 60%

From selling price you earn 37.5%. From cost you earn 60%.

Example 2: Coffee Shop (Setting Selling Price)

Problem:

Coffee $5, cup & sugar $3, want 50% margin. What selling price?

Solution:
  1. 1.Cost = 5 + 3 = 8
  2. 2.Selling Price = Cost / (1 − Margin%)
  3. 3.Selling Price = 8 / 0.5 = 16
Result:Selling Price: $16

For 50% margin, coffee must sell at $16 per cup.

Example 3: Online Shop (Target Markup)

Problem:

Buy item for $100, want 40% markup. Selling price?

Solution:
  1. 1.Markup = 100 × 40% = 40
  2. 2.Selling Price = 100 + 40 = 140
  3. 3.Margin = (40/140)×100% = 28.6%
Result:Selling Price: $140

With 40% markup, item sells at $140 with 28.6% margin.

Example 4: Frozen Food (Profit Evaluation)

Problem:

Cost $120 per box, sell $180. Is profit enough?

Solution:
  1. 1.Profit = 60
  2. 2.Margin = 33.3%
  3. 3.Markup = 50%
Result:Margin 33.3%, Markup 50%

33.3% margin is healthy for food business—profitable enough.

Frequently Asked Questions

What is the difference between profit margin and markup?
Profit margin is profit as a percentage of selling price; markup is profit as a percentage of cost price. If cost is $100 and selling price is $150, markup is 50% (of cost) while margin is 33.3% (of selling price). Margin is always smaller than markup for positive profit.
How do I use this profit margin calculator?
Enter cost price and selling price—the calculator computes margin and markup automatically. You can also enter cost and target margin to find the optimal selling price.
Why is profit margin important in business?
It helps you understand product profitability, set competitive prices, manage costs, and make strategic decisions. Investors also use margin to assess financial health.
