Plumbing Markup & Margin Calculator
Price parts and materials the right way — enter your cost and a markup, a target margin, or a sell price, and the calculator solves the rest, showing markup, margin, and gross profit side by side. A 50% markup is only a 33.3% margin, so plumbing shops that quote the wrong number leave money on every job. Free, no signup.

Margin is the green slice — profit as a share of the price you charge. Markup measures that same profit against the amber slice (your cost), so it always reads higher.

What you'll get
Enter your cost and pick what you know
Start with what you pay for the part or material. Then choose a mode: enter a markup, a target margin, or the sell price you have in mind — you only fill in one.
Get sell price, markup, and margin together
The calculator returns the sell price, gross profit, markup percent, and margin percent at once — plus a cost-vs-profit split so the difference between markup and margin is obvious.
Price to the margin you actually keep
Use the markup-to-margin conversion table and trade benchmarks to check your numbers, then set prices that hit the gross margin your business needs.

How plumbing contractors use a markup and margin calculator
Markup and margin describe the same sale from two directions, and mixing them up is one of the most expensive pricing mistakes contractors make. Markup measures profit against what you paid for the part; margin measures that same profit against what you charge the customer. Because the denominators differ, the numbers never match — a 50% markup is a 33.3% margin, and a 100% markup is only a 50% margin. Quote a "50% margin" when you actually applied a 50% markup and you have quietly underpriced the job.
This calculator removes the guesswork. Enter your landed cost and one driver — a markup, a target margin, or the sell price — and it back-solves the rest with the textbook formulas (price = cost × (1 + markup), price = cost ÷ (1 − margin)), then shows markup, margin, and gross profit together. Materials markup commonly runs 20–50% for plumbing work, with small parts often doubled or more; use the built-in benchmarks and conversion table to sanity-check your pricing. Pair it with the Profit Margin and Job Pricing calculators so the prices you quote clear both your parts margin and your whole-job overhead.

What is the difference between markup and margin?
Markup is profit as a percentage of your cost: (price − cost) ÷ cost. Margin is profit as a percentage of the sell price: (price − cost) ÷ price. On the same sale, markup is always the larger number. A part that costs $100 and sells for $150 has a 50% markup but a 33.3% margin.
How do I convert markup to margin?
Divide the markup by 100 plus the markup: margin = markup ÷ (100 + markup) × 100. So a 50% markup is 50 ÷ 150 = 33.3% margin, and a 100% markup is 100 ÷ 200 = 50% margin. To go the other way, markup = margin ÷ (100 − margin) × 100.
How much should plumbing contractors mark up parts and materials?
Materials and equipment markups commonly run 20–50%, while smaller parts, fittings, and consumables are often marked up 50–100% or more to cover procurement, handling, warranty, and stocking. Set your markup so the resulting gross margin covers overhead and leaves the net profit you target — not just to match a competitor.
Is this markup and margin calculator free?
Yes. Every tool on CloseCrew is free for contractors — no account required. Use it with the Profit Margin, Labor Rate, and Job Pricing calculators to price parts, labor, and whole jobs for healthy margins.
