How to convert between markup and margin
Translate cost-plus markup percentages into sale-price margins (and vice versa) so your bids hit the profitability you actually intend.

Pick the direction you're converting
Use the markup-to-sale form if you have a cost and want to add a percentage to it. Use the margin-to-sale form if you have a cost and want to back into a sale price that produces a target margin. Most contractors should think in margin — it's how the financial statement reads.

Enter your hard cost
Hard cost = direct job cost: materials + burdened labor + sub costs + equipment + permits. Don't include overhead allocation here — overhead lives inside the markup or margin you apply on top.

Enter the markup OR margin percentage
If you charge cost + 30%, that's a 30% markup → enter 30 in the markup form. If you want every dollar of revenue to contain 25 cents of profit, that's a 25% margin → enter 25 in the margin form. Critically, 30% markup ≠ 30% margin — a 30% markup yields only a 23% margin.

Read the conversion
The output shows the resulting sale price, the profit dollars, and BOTH the markup percentage and margin percentage so you can see how they translate. Use the conversion table to check your work — common contractor markups (1.30, 1.50, 1.67, 2.00) are listed with their margin equivalents (23%, 33%, 40%, 50%).

Apply consistently across estimates
Pick one (margin OR markup) and use it the same way on every job. Mixing them — quoting some jobs at 'cost + 30' and others at '25% margin' — guarantees inconsistent profitability and makes your quarterly P&L impossible to read. The pros think and price in margin.
The #1 pricing mistake in construction
A contractor pays $10,000 for materials, wants to make 25% on the job, adds 25% to the cost, and invoices $12,500. The customer pays it. The contractor nets $2,500. Feels like a 25% win.
It's not. 25% markup is 20% margin, meaning only 20 cents of every dollar collected is profit. And that margin has to cover labor, overhead, warranty, and everything else — before any real profit lands in the owner's pocket. Contractors who mix up markup and margin price low and never understand why the business feels so tight.
The formulas
- Markup = profit ÷ cost × 100. If cost is $1,000 and you add $250 of profit, markup is 25%. Sale price = $1,250.
- Margin = profit ÷ sale price × 100. Same $1,000 cost and $250 profit, sale price $1,250 — margin is 20%.
- Markup to margin: markup ÷ (1 + markup).
- Margin to markup: margin ÷ (1 − margin).
The quick gut-check chart every estimator should memorize:
| Markup % | Equivalent margin % |
|---|---|
| 10% | 9.09% |
| 15% | 13.04% |
| 20% | 16.67% |
| 25% | 20.00% |
| 30% | 23.08% |
| 33.3% | 25.00% |
| 40% | 28.57% |
| 50% | 33.33% |
| 66.7% | 40.00% |
| 75% | 42.86% |
| 100% | 50.00% |
| 150% | 60.00% |
Why margin is the right lens
Margin tells you what you keep out of every revenue dollar. If you run your whole business at 30% gross margin and 15% net margin, you can quickly sanity-check any bid: “on this $50k job I should keep $15k gross and $7,500 net — does that math work?” Markup doesn't let you do that sanity check because it's indexed to cost, not revenue.
Every financial statement a CPA, banker, or bonding agent will ever show you is in margin terms. P&L shows gross margin. Tax return shows net margin. If you're talking markup internally while everyone else is talking margin, you'll lose the plot.
Pricing from margin — the contractor formula
Sale price = cost ÷ (1 − margin). If your true cost on a job is $30,000 and you want to make 30% margin, sale price is $30,000 ÷ 0.70 = $42,857. Profit: $12,857, which is exactly 30% of $42,857.
If you had naively added 30% markup instead, the sale price would have been $39,000 and your margin would have been 23%. That $3,857 gap shows up directly in your bank account at the end of the year — and shows up compounded in years where you run 50+ jobs.
When markup is still useful
Markup is useful for back-of-napkin work when you know your cost and want to quickly add profit. “Bump it 50%” is a workable rule of thumb if you're consistent. But before any final bid, always convert to margin and verify the margin number matches your business's actual target. And never, ever trust a vendor's “discount off list” without running the numbers — list-price discounts are markup dressed up in different clothes.
Practical tips
- Publish your target margin internally — every estimator should know what it is and why.
- Different cost categories get different margins. Material is often marked up more than labor (15-25% vs 10-15%), because it includes risk and procurement overhead.
- Revisit margin targets annually. As your cost base grows (new hire, better insurance, bigger office), margin has to grow with it or net profit shrinks.
- Don't apologize for margin. The contractor running at 40% gross will be in business in 10 years; the one at 15% gross likely won't.
Frequently asked questions
What's the difference between markup and margin?
Markup is profit as a percentage of cost. Margin is profit as a percentage of sale price. A 50% markup is a 33.3% margin. A 100% markup is a 50% margin. They're the same profit dollars, just expressed from different angles — and confusing them is the single most common pricing mistake in construction.
Which should I use when pricing a job?
Use margin. Margin tells you what you keep out of every dollar the customer pays. Markup inflates how good your math looks without telling you that. 'We're 30% margin' means 30 cents of every dollar collected is profit. 'We're 30% markup' means roughly 23 cents of every dollar collected is profit. Price to margin, not markup.
Why do supply houses quote in markup?
Retail culture. Supply houses, big-box stores, and auto parts all talk markup because it feels more impressive ('we mark up 40%!') than the equivalent margin (28.5%). Contractors who buy off these vendors and then naively apply the same percentage on top of their cost are leaving real money on the table. Always convert to margin before pricing to the customer.
What's a healthy margin target for a contractor?
Gross margin 30-50% depending on trade. Service work, specialty trades, and time-and-material service contracts can hit 45-55%. Volume residential remodeling runs 25-35%. Commercial competitive bidding can be as low as 15-20% gross. Net margin after overhead should be 10-20% for a healthy operation; under 5% is red flag territory.
Does this calculator handle labor + material separately?
No, this is the conversion tool — markup to margin and vice versa on any total cost. For splitting labor vs material markup or applying different margins to different cost buckets, use the job cost allocation calculator or the contractor hourly rate calculator.
