See how a service-job price is built

A cost breakdown using Core's documented calculation. These sample assumptions illustrate the method; use your own costs, hours and fee rates.

Build the job cost

Five worker-hours, with owner pay included in labor
Cost assumption	Amount
Labor: 5 hours × $30	$150.00
Direct expenses	$40.00
Overhead: $600 ÷ 100 billable hours × 5	$30.00
Subtotal	$220.00
Contingency allowance: 10%	$22.00
Modeled cost per job	$242.00

Check the target price

With a 30% target operating margin, a 3% payment fee and a $0.50 fixed fee:

Target price before sales tax
$361.94

($242 + $0.50) ÷ (1 − 0.30 − 0.03)

At a current price of $350, the same assumptions leave $97 modeled profit after the entered fees and costs: a 27.7% margin.

Results depend on the inputs. Actual costs and what customers will pay still need your judgment.

Core lets you change these cost inputs and compare a target price with your current price. It requires a desktop browser and manual JSON backups.
