How do you calculate what your labor really needs to earn?

Start by separating four different numbers

Wage is what a worker earns. Loaded labor cost includes the employer costs connected to that worker. Billable or selling rate is what the customer is charged when labor is priced by time. Required contribution per productive hour is what the business needs left after direct costs to carry overhead, owner pay, and profit.

Those numbers may be very different, which is why simply doubling a wage is not a reliable pricing method for every business.

Calculate the productive capacity first

A person can be paid for 40 hours in a week without producing 40 customer-billable hours. Travel, setup, meetings, quoting, supply runs, training, cleanup, administration, and downtime all reduce productive capacity.

If an owner works 48 weeks per year, five days per week, and averages five productive hours per day, that is about 1,200 productive hours—not 1,920 or 2,080.

Then determine what those productive hours must carry

Add the annual overhead the business must cover, the owner's desired income, employee or helper costs that are not already treated as direct job costs, and the desired profit cushion. Then account separately for direct job costs so materials and subcontractors are not accidentally treated as overhead.

Why this matters on flat-rate jobs

Even if customers never see an hourly rate, productive-hour math still helps. A $1,500 job with $500 in direct costs leaves $1,000 of contribution. If it takes 8 productive hours, that is $125 per productive hour. If it takes 16 hours, it is only $62.50. The customer sees the same flat price, but the economics are completely different.

Employees require another layer

When you hire, include the real employer costs that apply to your situation and account for how much productive capacity the employee adds. A new hire can increase revenue capacity, but only if the business has enough work and enough margin to support the added fixed or semi-fixed cost.
