What This Calculator Does
This calculator builds a project bid price by layering overhead, contingency, and profit margin on top of direct job costs. It shows the complete cost buildup from direct costs to final bid price and calculates both the effective markup and effective margin percentages.
The Formula
A proper bid starts with direct costs (materials, labor, subs), adds overhead allocation, includes a contingency for unknowns, and then applies a profit margin. The overhead is a percentage of direct costs. Contingency protects against unforeseen conditions. Profit is the margin that sustains and grows the business.
Step-by-Step Example
Enter direct job costs
Total materials, labor, subcontractors, and equipment rental for the specific project. Example: $50,000.
Apply overhead rate
Your company overhead rate from the overhead calculator. Example: 25% adds $12,500.
Add contingency
5% is standard for well-defined scopes. Use 10-15% for renovation work with unknowns. Example: 5% adds $3,125.
Set profit margin
10% is a common target for general contractors. Example: 10% adds $6,563. Final bid: $72,188.
Real-World Use Cases
Bid Preparation
Systematically build competitive bids that cover all costs and generate target profit.
Markup Standardization
Ensure consistent pricing methodology across all estimators and project managers in your company.
Profit Analysis
See the actual dollar amount of profit in each bid and adjust margins based on project risk and competition.
Common Mistakes to Avoid
Applying a single markup percentage that is supposed to cover overhead, contingency, and profit together. This makes it impossible to know your actual profit on any job.
Using the same contingency for all project types. New construction is more predictable (3-5%) than renovation work (10-20%).
Forgetting that profit should be applied AFTER overhead and contingency, not just on direct costs.
Setting profit too low to win bids. A contractor earning 5% profit is one bad job away from losing money. Target 10-15% minimum.
