Profit Margin & Markup Calculator

Margin vs markup: the difference that trips everyone up

Margin and markup both describe your profit, but they divide it by different things, and mixing them up quietly eats your earnings. Margin is profit as a share of the price you charge. Markup is profit as a share of the cost to you. The same job can be “a 50% markup” and “a 33% margin” at the same time, so if a client or supplier says “50%”, always ask which one they mean. For the full story with more worked examples, see margin vs markup, explained.

How to use this calculator

The first section takes a cost and a price you are considering and tells you the profit, margin and markup. Use it when you are sanity-checking a quote, a retainer or a product price. The second section works the other way: tell it your cost and the margin you want to keep, and it tells you the price you need to charge to get there.

For freelancers, “cost” should include more than obvious out-of-pocket expenses. If you are quoting a fixed project, include your own delivery time valued at your real rate, subcontractors, software bought for the job, payment-processing fees and any materials. A margin that ignores your own labor is not a real margin.

One practical habit is to run the calculation twice: once with the costs you are sure about, and once with a less comfortable version that includes the extra meeting, the second revision round and the payment fee. If the margin only looks healthy in the optimistic version, the quote is fragile. Raise the price, narrow the scope, or write a clearer change-order line before the project starts.

A worked example

Suppose a project costs you $40 in time and tools, and you are thinking of charging $100. That is $60 profit: a 60% margin but a 150% markup. Now flip it. If a job costs $30 and you want to keep a 40% margin, you need to charge $30 / (1 - 0.40) = $50. Notice you cannot just add 40% to the cost; that would only give you a 28.6% margin. This is the trap the second section saves you from.

Why margins matter for freelancers

Your margin is your breathing room. It absorbs scope creep, slow months and the costs you forgot to count. Thin margins mean every surprise comes straight out of your pocket. Pricing to a deliberate target margin, rather than guessing, is one of the simplest ways to make freelancing sustainable. The guide on how to price a project walks through the practical quote-building side.

Who this calculator is for

Use it if you have a cost and a price and need to know what is left in between: freelancers quoting fixed-price projects, makers pricing physical products, small agencies sanity-checking subcontracted work, and side hustlers trying to figure out whether a $25 product that costs $19 to make and ship is actually worth the effort. If you have ever added “a bit on top” of your costs and hoped for the best, this page is for you.

Assumptions and limitations

• Your cost must be fully loaded. Include your own time, subcontractors, software, transaction fees and shipping.
• Figures are pre-tax. Quote and compare prices net of sales tax or VAT you collect for the government.
• Target margin must stay below 100%. Price grows without bound as the target approaches 100%.
• Overheads spread across many jobs are not modeled. Annual software and insurance usually belong in your rate or yearly planning unless the job genuinely consumes them.
