Contractor pricing formulas
Markup vs margin for contractors: formulas, conversions, and pricing examples
Markup and margin describe the same profit from two different viewpoints. Mixing them up can leave a construction quote below the profit target even when the arithmetic looks correct.
The difference in one sentence
Markup compares profit with cost. Margin compares profit with selling price.
Both percentages can describe the same quote, but they will not be equal. A contractor who intends to earn a 20% margin and adds a 20% markup will miss the target.
Markup formula
Markup = Profit / Cost
Useful for seeing how much profit was added relative to the internal cost base.
Margin formula
Margin = Profit / Selling price
Useful for seeing how much of the revenue remains as profit after internal cost.
One job, two percentages
A job costs $8,000 internally and sells for $10,000 before tax. Profit is $2,000.
Markup
$2,000 / $8,000 = 25%
Margin
$2,000 / $10,000 = 20%
Convert markup and margin
Margin = Markup / (1 + Markup)
Markup = Margin / (1 - Margin)
Use decimal values in the formulas. For example, 30% markup is 0.30. The resulting margin is 0.30 / 1.30, or about 23.1%.
| Markup | Equivalent margin | Price on $10,000 cost |
|---|---|---|
| 10% | 9.1% | $11,000 |
| 20% | 16.7% | $12,000 |
| 25% | 20.0% | $12,500 |
| 33.3% | 25.0% | $13,333 |
| 50% | 33.3% | $15,000 |
Why the distinction matters in construction
Construction estimates contain uncertainty. If a contractor targets 20% profit but accidentally prices at 20% markup, the starting margin is only 16.7%. One labor overrun, damaged material order, or callback can reduce it further.
Margin-first pricing also makes job comparison easier. A $5,000 repair and a $100,000 renovation can be evaluated using the same revenue-based profit measure, provided the underlying cost estimates are complete.
A better estimating habit
- Calculate complete internal cost.
- Select the target profit margin.
- Calculate the required pre-tax selling price.
- Review the resulting markup for comparison and reporting.
- Track actual cost and actual margin after completion.

Frequently asked questions
Is markup always higher than margin?+
For a profitable quote with the same cost and selling price, the markup percentage is higher than the margin percentage because markup divides by cost while margin divides by the larger selling price.
What markup produces a 20% margin?+
A 25% markup produces a 20% margin. On $100 of cost, a 25% markup creates a $125 price and $25 profit. The $25 profit is 20% of the $125 selling price.
What margin does a 30% markup produce?+
A 30% markup produces approximately a 23.1% margin. Divide 0.30 by 1.30, then multiply by 100.
Should contractors price with markup or margin?+
Either can be used consistently, but margin is often clearer for setting a profit goal because it measures profit as part of revenue. Veltril Quote prices from target margin and reports the resulting markup.
