Contractor Markup Calculator
Free Contractor markup Calculator for construction cost projects. Enter dimensions to get material lists and cost estimates.
Formula
Selling Price = Direct Cost x (1 + Overhead) x (1 + Contingency) x (1 + Profit)
The selling price is calculated by applying overhead, contingency, and profit percentages sequentially to the direct cost. Overhead covers indirect business expenses, contingency provides a buffer for unforeseen costs, and profit is the net return on the project. The total markup percentage equals (Selling Price - Direct Cost) / Direct Cost x 100.
Worked Examples
Example 1: Residential Remodel Bid
Problem: A kitchen remodel has $50,000 in direct costs. Apply 15% overhead, 5% contingency, and 10% profit.
Solution: Overhead: $50,000 x 0.15 = $7,500\nSubtotal: $57,500\nContingency: $57,500 x 0.05 = $2,875\nSubtotal: $60,375\nProfit: $60,375 x 0.10 = $6,037.50\nSelling price: $66,412.50
Result: Selling price = $66,412.50 (32.8% total markup)
Example 2: Commercial Project Bid
Problem: A commercial project has $200,000 in direct costs with 18% overhead, 8% contingency, and 12% profit.
Solution: Overhead: $200,000 x 0.18 = $36,000\nSubtotal: $236,000\nContingency: $236,000 x 0.08 = $18,880\nSubtotal: $254,880\nProfit: $254,880 x 0.12 = $30,585.60\nSelling price: $285,465.60
Result: Selling price = $285,465.60 (42.7% total markup)
Frequently Asked Questions
What is the difference between markup and margin?
Markup and margin are related but calculated differently. Markup is the percentage added to the direct cost to arrive at the selling price, calculated as (Selling Price - Cost) / Cost x 100. Margin is the percentage of the selling price that represents profit, calculated as (Selling Price - Cost) / Selling Price x 100. For example, a job that costs $100 and sells for $130 has a 30% markup but only a 23.1% margin. Many contractors confuse these terms, which can lead to underpricing if they apply a margin percentage as a markup. A 20% margin requires a 25% markup.
What markup percentage should a contractor use?
Most successful contractors use a total markup of 25% to 50% on direct costs, which includes overhead recovery and profit. General contractors typically mark up 20-35% over subcontractor costs and 10-20% for overhead plus 10-15% for profit. Specialty contractors may use higher markups of 40-60% because they carry more specialized equipment and training costs. The right markup depends on your overhead structure, local market conditions, competition, and desired profit level. The key is to ensure your markup covers all overhead costs and provides a reasonable net profit.
