Percentage Markup- Practice Questions and Solutions

Percentage Markup — Practice Questions and Solutions

Percentage markup is how businesses turn a cost into a selling price. You take what you paid, slap on a percentage, and that's what the customer pays. Simple in theory. Easy to mess up in practice.

This post gives you real questions, real numbers, and real solutions. No fluff. Just the math you need to price things correctly or pass your exam.

🧮 What Percentage Markup Actually Means

Markup is the difference between your cost and your selling price, expressed as a percentage of the cost.

Formula: Markup % = ((Selling Price - Cost) / Cost) × 100

Notice it's based on cost, not selling price. That's where most people trip up. If you base it on selling price, you're calculating margin, not markup. Different beast.

📋 Practice Questions

Question 1: Find the Selling Price

A retailer buys a jacket for $80 and wants a 25% markup on cost. What's the selling price?

Solution:

First, find the markup amount: $80 × 0.25 = $20.

Then add it to the cost: $80 + $20 = $100.

The selling price is $100.

Question 2: Find the Cost Price

A gadget sells for $150 with a 50% markup on cost. What did the store pay for it?

Solution:

Let the cost be C. The selling price equals cost plus 50% of cost.

So: $150 = C × 1.50

C = $150 / 1.50 = $100.

The cost was $100. Not $75. If you calculated 50% of $150 and got $75, you confused markup with margin.

Question 3: Find the Markup Percentage

A phone costs $400 to stock and sells for $520. What's the markup percentage?

Solution:

Markup amount: $520 - $400 = $120.

Markup %: ($120 / $400) × 100 = 30%.

Question 4: Markup with Multiple Items

A bakery spends $2.50 on ingredients per cupcake. They want a 60% markup. What should each cupcake sell for?

Solution:

Markup: $2.50 × 0.60 = $1.50.

Selling price: $2.50 + $1.50 = $4.00.

Question 5: The Trap Question

A car part is marked up 20% and sells for $240. What was the cost?

Solution:

If cost is C, then C × 1.20 = $240.

C = $240 / 1.20 = $200.

Again, the answer isn't $192. Don't subtract 20% from $240. That calculates margin, not cost.

⚔️ Markup vs. Margin — Know the Difference

People use these words interchangeably. They're wrong.

If your boss asks for a "40% margin," they mean 40% of the selling price. If they say "40% markup," they mean 40% of the cost. Mix them up and your numbers will be wrong.

🛠️ How to Calculate Markup Fast

Here's a dead-simple process you can use right now:

• Write down your cost per unit
• Decide your markup percentage
• Convert the percentage to a decimal and add 1
• Multiply that by your cost

Example: Cost = $50, markup = 35%.

Multiplier: 1 + 0.35 = 1.35.

Selling price: $50 × 1.35 = $67.50.

That's it. One multiplication. No extra steps.

💀 Common Mistakes That Kill Your Numbers

• Using margin instead of markup. A 25% markup and 25% margin give completely different prices. Always check which one your boss or textbook means.
• Forgetting to add 1. If you just multiply cost by the markup percentage, you get the profit amount, not the selling price. Add the cost back in.
• Marking up the wrong base. Markup is always on cost. If you calculate 20% of the selling price and call it markup, you're doing math from another planet.
• Ignoring overhead. Markup covers profit. It doesn't cover rent, labor, or shipping. If you need those covered too, your markup needs to be higher or you need a separate calculation.

🔥 Advanced: Handling Discounts After Markup

Sometimes you mark something up, then put it on sale. The math stacks.

Question: A shirt costs $30. You mark it up 60%, then offer a 20% discount. What's the final price?

Solution:

Marked-up price: $30 × 1.60 = $48.

Discounted price: $48 × 0.80 = $38.40.

Notice the final price isn't just cost + 40%. Discounts apply to the selling price, not the cost. Stack the operations in order.

✅ The Bottom Line

Percentage markup is cost × (1 + rate). That's the whole game.

Get the base right. Get the formula right. Check whether you're dealing with markup or margin before you touch a calculator. Everything else is just arithmetic.
