Job Bid Builder

How It Works

1. Enter Direct Costs

   Input labor cost (total crew hours times burdened hourly rate), material cost (quotes from suppliers), equipment cost (rental rates or ownership cost per day times duration), and subcontractor quotes. Each category is tracked separately for cost breakdown reporting.

2. Set Overhead Percentage

   Enter your company overhead as a percentage of direct costs. Use actual indirect-cost records and a consistent allocation policy; the local benchmark rows are broad planning ranges, not CFMA survey extracts.

3. Set Profit Target

   Enter profit as a markup percentage on total cost plus contingency. The calculator shows bid price and effective margin, then flags low-margin conditions for review. Local profit rows are caution ranges, not pricing recommendations.

4. Add Contingency and Bond Costs

   Optionally add contingency for unknowns, scope gaps, escalation, or schedule risk. If a bond is required, enter a simple bond-rate assumption and verify the actual surety premium tier, contract value, warranty or maintenance term, and accounting treatment separately.

5. Review Bid Summary

   The output shows the cost breakdown, subtotals by category, overhead amount, contingency, profit, simple bond cost, screened bid price, effective margin, break-even price, and optional unit pricing. Export the summary as planning documentation, not as a substitute for a formal estimate package.

Built For

• General contractors assembling lump-sum bids for residential remodels or commercial tenant improvements
• Subcontractors pricing their scope of work (electrical, plumbing, HVAC) for GC bid packages
• Small contractors and sole proprietors verifying that overhead and profit are adequately covered before submitting a quote
• Estimators comparing bid scenarios at different profit margins before market and contract review
• Construction managers reviewing subcontractor bids to verify that markup and contingency percentages are reasonable

Features & Capabilities

Markup vs. Margin Clarity

Enter profit as a markup on cost and the calculator shows the resulting effective margin (profit as a percentage of bid price). Many contractors accidentally confuse markup and margin, leaving profit on the table. The effective margin is always lower than the markup percentage.

Bond Cost Estimator

Calculates the surety bond premium as a percentage of the final contract price. Bond rates vary by contractor qualification, project size, and bonding company. The calculator applies the rate to the total bid including overhead and profit, as sureties charge on the full contract amount.

Cost Breakdown Report

Generates a planning summary showing each cost category as a percentage of the total bid. Useful for identifying whether labor, materials, equipment, subs, overhead, contingency, profit, or bond assumptions dominate the calculator result.

Assumptions

• Labor costs are assumed to be fully burdened (wages plus payroll taxes, insurance, and benefits). Use the Hourly Burden Calculator if you need to compute burdened rates.
• Overhead percentage is applied to total direct costs. Some companies allocate overhead differently (e.g., as a percentage of labor only). Adjust your input accordingly.
• Bond cost is calculated on the total contract price including overhead and profit. Some bid forms require the bond cost to be listed separately.
• Contingency is intended to cover estimating uncertainty, not scope changes. Scope changes should be handled through the change order process.

Limitations

• Does not generate a full CSI-format estimate with division breakdowns.
• Does not account for escalation clauses on multi-year projects.
• Does not model full unit-price bid formats with separate pay items, quantity takeoff, alternates, or allowances.
• Applies only a user-entered material tax percentage and does not determine taxability, exemptions, jurisdiction, or filing treatment.
• Does not validate whether the bid price is competitive for a given market. Use historical bid-to-win ratios for that analysis.
