Engineering Team Payroll & Expenses

What it measures

The fully loaded monthly cost of every engineer on payroll: base salary, bonuses or commissions, health insurance (employer portion), retirement contributions, equity grants amortized monthly, payroll taxes, and employer-paid benefits (commuting, wellness, training, etc.). It captures total labor cost tied to the engineering function; contractors and outsourced development are excluded and belong to R&D contractor expenses.

Why it matters

Engineering is typically your largest operating expense after sales and marketing. You track it to calibrate hiring velocity against revenue growth, to model runway, and to hold engineering leadership accountable for cost-per-product-output. Boards use this line to sense-check whether you're over-hiring, under-hiring, or running a sustainable burn rate toward profitability.

How to read it

Read Engineering Payroll in two ways: (1) as a trend — is it accelerating faster than revenue? If yes, you're burning down runway too quickly; (2) as a ratio — divide it by monthly ARR to get cost per $1M in revenue. A rising ratio suggests you're hiring faster than you're upselling; a falling ratio shows you're gaining operating leverage. Always compare month-over-month to separate one-time events (new hires ramping, benefits resets) from structural changes.

What good looks like

Watch-outs

• Including non-engineering headcount (product, design, QA) if they report to another department. If your product and design teams report to a separate Chief Product Officer, their costs belong to that function, not engineering. Only include people who report into engineering leadership.
• Omitting benefits and taxes, counting only base salary. Fully loaded cost is 1.3–1.5× base salary once you add health insurance, 401k match, payroll taxes, and other benefits. Understating the cost distorts runway calculations and makes hiring decisions look cheaper than they are.
• Double-counting when reconciling to total operating expenses. Engineering Payroll is a component of R&D Expenses, not a separate line. Include it once, either as part of R&D or as a standalone metric, but never sum both into total burn.
• Treating contractor spend as engineering payroll. Contractors are variable cost; employees are fixed. They deserve separate lines so you can see how much of your engineering capacity is permanent versus outsourced.
