Labor Effectiveness Ratio (LER)

Formula

Labor Effectiveness Ratio = Gross Profit ÷ Direct Labor Cost

Direct labor cost is salaries. Not payroll taxes, not benefits, not contractors. Each of those is measured somewhere else, and folding them in here makes the ratio both harder to read and harder to compare against anything.

Nobody describes their pay as "$100,000 plus payroll taxes and benefits." They say $100,000. Even a total compensation conversation leaves taxes and benefits out of the headline. The ratio should run on the number people actually reason with.

What counts as direct labor

Direct labor is the employees who produce the work you sell, and who stay on payroll when revenue stops. Contractors are cost of goods sold. Administrative staff are measured against the Salary Cap instead.

The distinction is doing real work here. The ratio is asking whether the fixed cost of production is covered by what production earns, so anything that scales down when revenue scales down does not belong in the denominator.

What the bands mean

Ratio	Reading
Below 1.5x	The team is not paying for itself.
1.5x to 2.0x	Surviving, with no margin for error.
2.0x to 3.5x	Normal for most service firms.
3.5x to 5.0x	A better firm than most.
Above 5.0x	Exceptional leverage, or underpaid staff, and it is worth knowing which.

These bands assume the direct-labor denominator above. A ratio built on total labor cost reads lower and is not comparable to them.

Most service firms live between 2.0x and 3.5x. That range is normal. Normal is not the same as healthy, and the distance between those two words is where most of the available margin is sitting.

Why "effectiveness" and not "efficiency"

The concept originates with Greg Crabtree, who named it the Labor Efficiency Ratio in Simple Numbers, Straight Talk, Big Profits. We have used "Effectiveness" for 15 years, because efficiency measures output against input while effectiveness measures output against the goal. A team can be highly efficient at work that produces no margin.

That distinction matters more, not less, as AI compresses the cost of the input. When the input gets cheap, measuring against it tells you less every year.

What a weak ratio actually tells you

Less than most people assume. A weak ratio can mean overstaffing, underpricing, poor utilization, or scope creep. Those are four different problems with four different fixes, and the ratio cannot tell them apart.

The ratio tells you something is wrong. It does not tell you what. That part is the diagnosis, and it is a different job.

Common mistake

Putting the owner's salary into direct labor without normalizing it to a market rate. If you pay yourself irregularly, or take distributions when cash allows, the ratio will lie to you every month, and it will lie in a different direction each time.

Normalize first. Salary Cap covers the method.
