Job Costing Calculator

1. Select the job type. Choose the type of electrical job you are quoting. The calculator auto-fills typical install hours based on your selection: panel upgrades default to 8 hours, sub-panels to 5, whole house rewires to 24, EV charger installs to 4, generator hookups to 6, and lighting retrofits to 6.

2. Enter equipment cost and markup. Use your wholesale cost from the supply house. A 50% markup is a common starting point for major equipment like panels and transfer switches. Adjust based on your market.

3. Set labor details. Enter crew size, install hours, and your billable rate per electrician. The billable rate is what you charge the customer per electrician per hour, not the electrician's wage.

4. Configure materials. Use the checklist to toggle common material items on or off. The total auto-fills the materials cost field. Set your materials markup percentage to calculate the customer-facing price.

5. Add other costs and review. Include permit fees, disposal fees, and miscellaneous costs. Enter the number of circuits so the calculator can show your price per circuit. Review the full breakdown, profit, and margin.

Cost-plus pricing is the foundation. You start with your actual costs for equipment, labor, and materials, then add a markup to each category. The markup covers your overhead, warranty reserve, and profit. This method ensures you never sell a job below cost.

Target margin drives your pricing. Most electrical contractors aim for 25-40% gross margin on jobs. If the calculator shows you below 25%, you need to increase your markups, reduce costs, or both. Use the reverse calculator toggle to enter a target sell price and see what margin it gives you before sending the proposal.

Price per circuit is a quick benchmark. Dividing total sell price by the number of circuits gives you a per-circuit number you can compare across jobs and against competitors. Standard 20A circuits typically run $250 to $450 per circuit. Dedicated 240V circuits tend toward $350 to $600. If your number is significantly outside these ranges, investigate why.

Building a quote in the field. You have finished the site survey and need to quote the customer before you leave. Plug in your equipment cost from the supply house, set your standard markups, and adjust the hours based on the difficulty of the job. Walk the customer through the price with confidence because you know the margin is healthy.

Comparing job options for the customer. Run the calculator for a panel upgrade, then again for a sub-panel install. Show the customer both price points side by side. The equipment, hours, and material costs change, so the total and price per circuit shift. This helps the customer make an informed decision and positions you as a consultant, not just a bidder.

Training your sales team on pricing. New salespeople often discount too aggressively to close deals. Have them use this calculator to see exactly what happens to profit margin when they knock $500 off the price. When they see the margin drop from 32% to 22%, they learn to protect the price or find other ways to add value.
