How the Calculator Works

This calculator determines the markup needed to cover your overhead and achieve your profit target:

  1. Direct costs are your materials and labor for the job
  2. Overhead is added as a percentage of direct costs
  3. Profit margin is your target percentage of the selling price
  4. The calculator outputs the total markup multiplier and selling price

Include Overhead First

Before calculating profit markup, make sure your overhead is included in the base cost. The formula above assumes you have already added your overhead allocation to direct costs.

Full Pricing Formula

For complete job pricing with separate overhead and profit:

  1. Step 1: Total Cost = Direct Costs × (1 + Overhead Rate)
  2. Step 2: Selling Price = Total Cost ÷ (1 – Target Margin)

Example: $10,000 direct costs, 35% overhead, 20% profit target

  • Total Cost = $10,000 × 1.35 = $13,500
  • Selling Price = $13,500 ÷ 0.80 = $16,875
  • Profit = $16,875 – $13,500 = $3,375 (20% of selling price)
