How to Calculate a Contractor Bid

Formula

Bid Total = (Labor + Materials + Overhead) x (1 + Profit Margin% / 100)

A solid bid covers all your costs and includes a fair profit. Underestimating costs leads to losses. Make sure to include all overhead items and add a contingency buffer to material and labor estimates.

计算示例

A contractor bids on a job with $8,000 labor, $5,000 materials, $2,000 overhead, and wants a 15% profit margin.

  1. Base cost = $8,000 + $5,000 + $2,000 = $15,000
  2. Profit = $15,000 x 15% = $2,250
  3. Bid total = $15,000 + $2,250 = $17,250
