Sell price and gross margin
Contractors often confuse markup and margin. This calculator shows both from the same estimate.
Example scenario
A tenant-improvement electrical package carries twenty-eight thousand five hundred dollars of burdened direct job cost after pulling vendor quotes, labor burden tables, and allocated shop overhead consistent with the estimator’s work breakdown structure. Pricing committee applies thirty-five percent markup on cost to recover risk, supervision spillover, and contribution toward corporate SG&A embedded in company policy. That policy lifts quoted selling price toward thirty-eight thousand five hundred seventy-five dollars while the gross margin implied on sell dollars settles near twenty-six percent—far lower than thirty-five percent markup implies once profit divides by price rather than cost.

How to translate job cost, markup, and gross margin on bids
- Build estimated project cost from your cost database or export—labor, material, equipment, subcontracts, and job-specific fees before profit line items your policy books above margin.
- Slide markup on cost to the percentage your financial model needs to clear overhead, bond, and profit—separate contingency from pure markup if internal controls require both line items.
- Read selling price as cost times one plus markup—compare to owner budget caps and alternates before you lock schedule-of-value line items.
- Inspect resulting gross margin on sell dollars before you sign—tight margin on price explains why boards demand higher markup even when win-rate pressure tempts lower numbers.
Markup versus margin literacy on real job sites
- Trade and contract-type dispersion
- Service-and-repair shops often print higher markups on small tickets while heavy-civil low-bid work compresses both—peer-group medians mislead when risk profiles differ
- Loaded cost definition
- Accurate markups require fully loaded labor, equipment, tax-on-material, and fee lines your accounting system already capitalizes into cost—marking up bare trade dollars starves bond, insurance, and warranty reserves
- Language with owners and subs
- Clients hear margin colloquially while estimators think markup on cost—this tool surfaces the margin translation that keeps financial covenants and fee recovery models aligned
Best use cases
- Growth and performance planning
- Budget and forecast scenario modeling
- Client-facing pre-qualification and education
Frequently asked questions
Why is gross margin on the bid always lower than markup on cost for positive markups?
Because margin divides profit by selling price while markup divides profit by cost—the same dollars of profit shrink as a percentage when the denominator adds markup to the base cost.
Should project cost include home-office overhead allocation?
Only if your enterprise marks up variable direct cost to recover general conditions—double-count if corporate OH already loads through burden rates baked into labor dollars.
Can I invert margin targets back into required markup?
Yes algebraically—margin m implies markup m divided by one minus m expressed as decimals—this calculator starts from markup convenience typical on estimating spreadsheets.
Does selling price include prevailing wage fringe passthrough?
When statute mandates additive fringe billing, either embed fringe inside loaded cost before markup or treat additive lines separately—keep mechanics aligned with how pay apps reconcile certified payroll.
