See how much of your revenue goes to labor. Enter your labor cost and your revenue for the period — and get labor as a percentage of sales.
A general health metric — target ranges vary a lot by industry (restaurants often watch a ~25–35% range; other services differ). Compare against your own trend and industry norms.
Labor is often the biggest controllable cost in a service or food business. Tracking it as a percentage of revenue — not just a dollar figure — tells you whether you're staffing profitably as sales rise and fall.
A payroll figure on its own is unreadable. Six thousand dollars of wages is either comfortable or fatal depending entirely on what came in the door beside it, and that is the whole reason this ratio exists: it converts your largest controllable cost into a share of the thing that has to pay for it. The consequence people miss is that the ratio has two moving parts. Labor percentage rises when you pay more or when you sell less, and a slow month produces exactly the same warning light as a hiring mistake.
Defaults are $6,000 of labor cost against $20,000 of revenue for the period. That is 6,000 ÷ 20,000 = 30%, and it leaves $14,000 for everything else — rent, materials, insurance, software, marketing and your own profit. Read the leftover rather than the percentage and the number starts doing work: if rent, materials and overhead come to $12,000, this period earns $2,000, and a two-point move in labor percentage is $400 of that profit, or a fifth of it.
Now move each part separately, because they behave differently. Add $2,000 of labor — one more part-time person — with revenue unchanged and you are at 8,000 ÷ 20,000 = 40%, with $12,000 left. For that hire to leave the ratio where it started, revenue would have to reach $26,667, which is the real question to ask before hiring: can this person plausibly bring in another $6,667 of sales? Now hold labor still and let revenue slip 15%, to $17,000: the percentage climbs to 35.3% and the leftover falls to $11,000 — nobody got a raise, and the business is $3,000 worse off. A genuinely quiet period at $15,000 of revenue puts the same $6,000 of labor at 40%. That asymmetry is the argument for scheduling against forecast demand rather than habit: fixed labor against variable revenue is how service businesses lose money in slow weeks.
Most people compute this on gross wages and stop, which understates it. Labor cost means the fully burdened cost of employing people: gross wages plus the employer's share of payroll taxes — FICA alone is 7.65% of wages on the employer side — plus unemployment insurance, workers' compensation, any benefits you pay, and paid time off. Run the defaults the wrong way and the distortion is easy to see: if that $6,000 was wages only and your burden adds 15%, your real labor cost is $6,900 and your real ratio is 34.5%, not 30%. Decide whether your own pay is in or out, write the decision down, and never change it mid-year — a ratio is only meaningful against its own history, and the fastest way to make a trend lie is to redefine the numerator halfway through it.
Published targets exist — restaurants are commonly discussed in a mid-20s to mid-30s percent range — but they vary enormously by industry, by service model and by whether the business is capital-heavy or people-heavy, and a consultancy that is almost entirely payroll can run far higher and still be extremely profitable. Treat any external benchmark as context, not a target. The comparison that actually tells you something is your own figure month over month on the same definition, and the pairing that tells you more: labor percentage beside revenue per employee, because falling productivity and a rising labor share are the same problem seen from two sides. And if the ratio is drifting up while the leftover shrinks, the question is whether the business still clears its break-even point at current volume.
This ratio is worthless as a one-off and valuable as a series. A single 30% reading tells you almost nothing; twelve monthly readings tell you whether staffing is tracking sales or quietly decoupling from them, and they do it early enough to act. That requires labor and revenue captured in the same periods, on the same definitions, month after month — which is a record, not a calculation. Our small business bookkeeping template keeps both lines on one dashboard so the percentage plots itself.
Divide total labor cost by revenue for the same period and multiply by 100. This calculator does it and shows what's left for everything else.
It's highly industry-specific — restaurants often aim in the mid-20s to mid-30s percent, while other services differ. The most useful comparison is your own trend over time.
