Q: What is the difference between margin and markup?

Margin is profit as a percentage of the selling price; markup is profit as a percentage of the cost. A product bought for 60 dollars and sold for 100 dollars has a 40% margin but a 66.7% markup.

Q: What is a good profit margin?

As a broad rule of thumb, a 10% net margin is average, 20% is good, and 5% is low. Gross margins vary by industry — software often exceeds 70%, while retail commonly runs 20-40%.

Q: How is the break-even point calculated?

Break-even units equal fixed costs divided by the contribution margin per unit (selling price minus variable cost per unit).

Q: How much does an employee really cost beyond salary?

Employer taxes, benefits, equipment and overhead typically add 25-40% on top of base salary, so a 60,000 dollar hire usually costs 75,000 to 84,000 dollars per year.

How These Calculators Work

What is the difference between margin and markup?

Margin is profit as a percentage of the selling price; markup is profit as a percentage of the cost. A product bought for $60 and sold for $100 has a 40% margin but a 66.7% markup. Confusing the two is one of the most common pricing mistakes in small business.

What is a good profit margin?

It depends on the industry. As a broad rule of thumb, a 10% net margin is considered average, 20% is good, and 5% is low. Gross margins vary far more — software businesses often exceed 70%, while retail and food service commonly run 20–40% gross.

How is the break-even point calculated?

Break-even units = fixed costs ÷ contribution margin per unit, where contribution margin is the selling price minus the variable cost per unit. Once you sell that many units, every additional sale contributes directly to profit.

What counts as a good marketing ROI?

A common benchmark is a 5:1 revenue-to-spend ratio (400% ROI) for a good campaign, with 10:1 considered exceptional. Anything below about 2:1 usually means the campaign is unprofitable once product costs are included.

How much does an employee really cost beyond salary?

Employer taxes, benefits, equipment, and overhead typically add 25–40% on top of base salary. That is why a $60,000 hire usually costs the business $75,000–$84,000 per year — a multiplier of roughly 1.25× to 1.4×.
