Example Data Table

Formula Used

• Direct Cost = Labor + Materials + Equipment + Subcontract + Other.
• Overhead Amount = Direct Cost × (Overhead % ÷ 100).
• Contingency Amount = (Direct Cost + Overhead Amount) × (Contingency % ÷ 100).
• Estimated Cost = Direct Cost + Overhead Amount + Contingency Amount.
• Selling Price (Markup mode) = Estimated Cost × (1 + Markup % ÷ 100).
• Selling Price (Margin mode) = Estimated Cost ÷ (1 − Margin % ÷ 100).
• Net Price = Selling Price − (Selling Price × Discount % ÷ 100).
• Tax Amount = Net Price × (Tax % ÷ 100).
• Profit = Net Price − Estimated Cost.
• Markup % = (Profit ÷ Estimated Cost) × 100.
• Margin % = (Profit ÷ Net Price) × 100.

Professional Guide to Markup, Margin, and Bid Pricing

1) Why markup control matters

Markup is the percentage added to estimated cost to create a selling price. In construction, small pricing shifts can decide whether a bid wins, yet uncontrolled pricing can erase profit through rework, delays, or underestimated labor. This calculator helps you separate cost, profit, and invoice totals so decisions are transparent.

2) Start with defensible direct costs

Direct costs are the items you can trace to the job: labor, materials, equipment, subcontractors, and other direct charges. Better inputs improve price accuracy. For example, labor should reflect crew mix and productivity assumptions, and equipment should include ownership or rental time, fuel, and maintenance allowances.

3) Add overhead as a true burden

Overhead represents business costs that keep projects running: supervision, insurance, office support, vehicles, and compliance. Many contractors express overhead as a percentage applied to direct cost. If overhead is understated, your “profit” may only be paying the company’s fixed expenses. Use the overhead field to model realistic burden.

4) Use contingency to price risk

Contingency is not “extra profit.” It is a planned allowance for uncertainty such as scope gaps, site constraints, weather, market volatility, and coordination risk. Applying contingency after overhead mirrors how risk increases with job size and complexity. Sensible contingency keeps bids stable without overstating the base estimate.

5) Markup versus margin conversion

Markup is based on cost, while margin is based on selling price. A 20% markup does not equal a 20% margin. The calculator shows both so you can communicate consistently with owners, estimators, and finance. Use margin mode when management sets targets in margin terms, and markup mode when pricing is cost-driven.

6) Discounts and tax sequencing

Discounts are modeled before tax, which matches common invoicing practice. This matters because a discount reduces taxable base and changes profit. If you offer early-payment or volume discounts, you can see how net price and margin move immediately. Tax is then calculated on the discounted net price.

7) Run sensitivity checks before submitting

Advanced estimating is scenario-based. Try multiple overhead and contingency settings, or compare markup and margin targets, to identify the “profit cliff” where a small discount or cost increase collapses margin. If the result looks tight, revise productivity, supplier quotes, or risk allowances before final approval.

8) Document the bid with exports

Clear documentation reduces disputes. The CSV export supports quick review in spreadsheets, while the PDF provides a shareable summary for approvals and client conversations. Store exports with the estimate, notes, and assumptions so future change orders and post-job reviews have a reliable baseline.

FAQs

1) What is the difference between markup and margin?
Markup is profit divided by cost, while margin is profit divided by selling price. They use different bases, so the same percentage value does not represent the same profitability.

2) Should overhead be included in cost?
Yes. If you exclude overhead, the “profit” may only cover business expenses. Treat overhead as part of job cost so markup and margin reflect true profitability.

3) When should I use margin mode?
Use margin mode when management sets targets as gross margin percentages. The calculator converts that target into a selling price that meets the margin based on your estimated cost.

4) How is contingency applied here?
Contingency is applied to direct cost plus overhead. This approach scales the allowance with project size and recognizes that risk grows as the managed cost base grows.

5) Why does discount reduce my markup so much?
Discounts reduce net price but do not reduce cost, so profit drops quickly. A small discount can significantly reduce margin, especially on low-markup bids.

6) Can I back-calculate markup from a client’s target price?
Yes. Select selling price mode and enter the target price. The calculator returns profit, markup, and margin based on your cost and your discount and tax settings.

7) Are taxes included in profit?
No. Tax is treated as a pass-through added to the discounted net price. Profit is calculated from net price minus estimated cost, helping you separate earnings from tax collection.
