Profit Margin & Markup Calculator

A profit margin and markup calculator shows how much money you actually make on a sale and how your price compares to your cost. Enter your cost and selling price above to see gross profit, profit margin, and markup — and use the second box to find the price you’d need for a target margin.

Margin vs. Markup: What’s the Difference?

Margin and markup describe the same profit from two different angles, and confusing them is one of the most common (and costly) pricing mistakes. Markup is profit expressed as a percentage of your cost — how much you added on top to get your price. Margin is profit expressed as a percentage of your selling price — how much of each dollar of revenue you keep. Because the denominators differ, the two numbers are never the same: a 100% markup is only a 50% margin. Knowing which one a supplier, report, or rule of thumb is referring to keeps your pricing decisions honest.

How to Use This Calculator

1. Enter your cost per unit — what the item costs you to buy or make.
2. Enter your selling price — what the customer pays.
3. Read your gross profit, profit margin, and markup, all updated instantly.
4. To work backward, enter a cost and a target margin in the second box to get the price you should charge.

How It Is Calculated

Gross profit is simply selling price minus cost. Profit margin is that profit divided by the selling price, shown as a percentage. Markup is the same profit divided by the cost, also as a percentage. To find a price from a target margin, the calculator divides your cost by one minus the margin (as a decimal) — so a $40 item at a 60% target margin needs a $100 price. These are the core numbers behind almost every pricing and profitability decision a business makes.

Why It Matters for Pricing

Pricing on instinct is how good businesses quietly lose money. If you set prices by adding a flat markup but think in terms of margin, you can end up with thinner profits than you expect — especially as costs rise. Margin is usually the more useful lens for running a business, because it tells you directly what share of revenue is left to cover overhead, wages, and profit after the cost of goods. Knowing your margin on each product also helps you spot which items truly carry the business and which are barely worth selling, so you can adjust prices, renegotiate costs, or focus on your most profitable lines.

Tips and Common Mistakes

• Don’t confuse margin with markup — a healthy-sounding markup can hide a thin margin.
• Build all your costs into “cost,” not just the purchase price — shipping, fees, and packaging count.
• Use margin to check whether a price leaves enough to cover overhead and still profit.
• Revisit prices when costs rise; a fixed markup can erode your margin over time.
• Compare margins across products to find your real money-makers.

Pricing for Profit: Beyond Simple Cost-Plus

Knowing your margin and markup is the foundation of pricing, but turning those numbers into prices that actually keep your business healthy takes a little more thought. The simplest approach is cost-plus pricing: take your cost, add a set markup, and that’s your price. It’s easy and ensures every sale covers its cost, but used alone it ignores two important things — your overhead and what the market will bear. The profit on each item has to cover not just the cost of that item but also rent, utilities, wages, software, marketing, and everything else it takes to keep the doors open. That’s why margin is such a useful lens: it tells you directly how much of each sale is left over to cover those fixed costs and still leave a profit. If your margin is thin, you may need to sell an unrealistic volume just to break even. It’s also worth remembering that customers don’t care about your costs — they care about value. A product that solves a real problem or saves customers time can often command a price well above a simple cost-plus figure, while a commodity item may be capped by what competitors charge no matter how you’d like to price it. This is where checking your margin on every product pays off: it reveals which items are genuinely profitable, which are barely worth stocking, and where you have room to raise prices without losing sales. Costs also drift upward over time, and a fixed markup quietly erodes your margin as they do, so it’s smart to revisit your prices periodically rather than setting them once and forgetting them. Don’t overlook the psychology of pricing either — how a price is presented, bundled, or anchored against a higher option can shift what customers are willing to pay. Use this calculator to ground every pricing decision in the real numbers, then layer in your overhead, your market, and the value you deliver. Prices set with all of that in mind hold up far better than a markup picked on instinct.

Frequently Asked Questions

What’s the difference between margin and markup? Markup is profit as a percentage of cost; margin is profit as a percentage of selling price. They describe the same profit but are different numbers.

Is a 50% markup the same as a 50% margin? No. A 50% markup on a $40 cost gives a $60 price and a 33% margin. The two only match at zero.

Which should I use to set prices? Many businesses set prices using markup but evaluate health using margin. The target-margin box above lets you price directly to the margin you want.

What counts as “cost”? Ideally every cost to get the item ready to sell — purchase or production cost, shipping, duties, fees, and packaging.

What is a good margin? It varies hugely by industry. Compare against typical margins in your field rather than a single universal target.
