How to use it
  1. Enter annual salary plus employer taxes, unemployment insurance, workers comp, health insurance, retirement match, PTO weeks, equipment, software, office space, training, and any recruiting cost. These are the full employment costs that budget owners usually underestimate when they look only at salary.
  2. Read total annual cost, cost multiplier, effective hourly rate, monthly burn, and the category breakdown. In the US, a loaded employee often lands around 1.25x-1.4x salary, so a multiplier above 1.5x means benefits and overhead are materially changing the economics of the hire.
  3. Use effective hourly rate, not salary divided by 2,000, as the true benchmark for expected output or ROI. If the monthly burn from one hire meaningfully compresses runway, the role must have a very clear revenue, delivery, or risk-reduction case.
  4. Use the breakdown to decide which cost levers are strategic and which are negotiable. Office space, recruiting, and software can sometimes be reduced without hurting hiring quality, while cutting health or retirement benefits often saves cash at a much higher talent cost.
  5. Re-run before every new hire, comp adjustment, or benefit renewal. Track loaded cost per employee and multiplier over time because slow growth in overhead often expands headcount burn faster than salary bands alone.

Agent playbook

  1. Resolve Employee Cost Calculator from /agent-tools.json and open its contract before execution.
  2. Validate inputs against the contract schema instead of scraping labels from the page UI.
  3. Open the browser page only when a person wants to review charts, assumptions, or related tools.

Agent FAQ

Should ChatGPT, Claude, or another agent click through the UI?

No. Start with /agent-tools.json, then follow the tool's contract URL. The page UI is for human review, not parameter discovery.

When do tools show Quick and Advanced?

Every tool opens in Quick Start first. Advanced Controls keeps the same scenario, reveals more assumptions or diagnostics, and every tool keeps AI integrations inline below the instructions.

When should an agent still open the browser page?

Open it when a human wants to sense-check the output, review the chart, or keep exploring related tools after the calculation finishes.

Questions people usually ask
What's the typical cost multiplier for employees?

In the US, expect 1.25x–1.4x salary as the total loaded cost. This includes employer taxes (~10.65%), benefits (~8–12%), and overhead (~5–10%). Different industries and countries vary.

What should I include in office space?

Pro-rate the total office rent by number of employees, or use a per-seat estimate ($3,000–$8,000/year depending on location). Remote employees can use $0 or a small home office allowance.

How do I calculate recruiting cost?

Total cost including recruiter fees, HR time, interviews, and onboarding. A typical hire costs $5,000–$30,000 depending on role. You can amortize this over the first year or annualize it.

Should I use this for freelancers or contractors?

No — freelancers already quote their fully-loaded rate. This is for W-2/full-time employees. Contractors handle their own taxes and benefits.

How do I reduce the total cost of an employee?

Lower PTO, remote work (reduce office space), reduce benefits, or lower salary. But remember: reducing benefits often means losing top talent. Focus on efficiency gains instead.

Why is effective hourly rate different from salary / 2000?

Because the true cost includes taxes, benefits, and overhead. Example: $100k salary ÷ 2000 hours = $50/hr salary-only. But total cost of $140k ÷ 2000 hours = $70/hr true cost.

Is this tool free and private to use?

Yes. AI Biz Hub tools are free, no-signup browser tools. Inputs stay in your browser unless you choose to share a URL.

Is this professional advice?

No. Outputs are business planning estimates — not legal, tax, or accounting advice.
