You\'re hiring. You\'re budgeting $100k for a new role. The actual cost to your business is $125-150k. Here\'s the breakdown of what makes a "$100k salary" cost so much more than $100k.
The 1.25-1.5x rule
Standard rule of thumb in U.S. business: total employee cost = salary × 1.25 to 1.5.
- Lean operations (small business, basic benefits): 1.25x
- Standard tech company: 1.35x
- Generous benefits, full overhead: 1.5x+
For a $100k salary, expect $125k-$150k all-in cost.
Where the extra 25-50% goes
1. Employer payroll taxes (~7.65%)
Federal Insurance Contributions Act (FICA):
- Social Security: 6.2% of wages up to $168,600 (2024 cap; rises annually).
- Medicare: 1.45% of all wages.
- Additional 0.9% Medicare for high earners (employee pays this).
Plus state-specific:
- Federal Unemployment (FUTA): 0.6%
- State Unemployment: 0.5–6% (varies)
- State disability insurance (some states): 0.5–1%
Total: typically 8–10% of salary in employer taxes.
2. Health insurance (~5–15% of salary)
Average employer cost:
- Single coverage: $7,000–10,000/year.
- Family coverage: $20,000–25,000/year.
For a $100k employee with family coverage, ~$22k/year. ~22% of salary if expensive plan; less for HMO.
3. Retirement (401k matching) (~3–6%)
Common: 401k match of 3–6% of salary, fully or partially vested over years.
$100k salary × 4% match = $4,000/year. Plus administrative costs.
4. Paid time off and holidays (~7–10%)
Standard U.S. PTO: 15–25 days/year + 8–12 holidays = 4–7 weeks paid not working.
If salary is $100k for 50 working weeks (after vacation), the per-week cost is $2,000. PTO/holidays cost ~$10k–14k of "salary for time not worked."
This is implicit in the salary but should be remembered when calculating productive output.
5. Worker's compensation and disability (~1–3%)
Cost varies by industry — office work much lower than construction.
- Office: 0.3–1% of salary.
- Manufacturing: 2–5%.
- Construction: 5–15%.
6. Other benefits (~3–8%)
- Life insurance: $50–200/year.
- Dental and vision: $300–800/year.
- Long-term disability: $200–500/year.
- Wellness benefits, gym, snacks: variable.
- Educational reimbursement: $1,000–5,000/year if offered.
- Bonuses: typically 5–10% of salary on average.
7. Office and equipment overhead (~10–20%)
Per-employee allocation:
- Office space: $500–2,000/month per person ($6k–24k/year).
- Computer + monitor: amortized $500–1,000/year.
- Software licenses: $1,500–3,000/year (Office, Adobe, Slack, etc.).
- Phone, mobile reimbursement: $500–1,500/year.
- Travel/expenses: variable.
Total: $10–30k+ per employee per year.
Worked example: $100k engineer
| Item | Cost |
|---|---|
| Salary | $100,000 |
| FICA + state taxes (8%) | $8,000 |
| Health insurance (single) | $8,000 |
| 401k match (4%) | $4,000 |
| PTO is implicit in salary | $0 added |
| Worker's comp (0.5%) | $500 |
| Other benefits | $2,500 |
| Office and equipment | $8,000 |
| Total | $131,000 |
Multiplier: 1.31×.
Worked example: senior with family coverage
$200k salary, family health coverage, generous benefits.
- Salary: $200,000.
- FICA + state (with cap effect on Social Security): $16,000.
- Health (family): $22,000.
- 401k match (6%): $12,000.
- Other benefits: $6,000.
- Office: $12,000.
- Total: $268,000.
Multiplier: 1.34×.
Contractor vs employee math
Contractors don't get benefits, so their cost is closer to their billed rate.
$120/hour contractor for 2000 hours = $240k.
Equivalent salaried employee at $150k all-in cost = $200k. Less than the contractor.
Why hire contractors anyway? Flexibility, specific expertise, no long-term commitment, no PTO/insurance overhead.
Implications for pricing
If you bill clients for an employee's time, you must charge enough to cover all-in cost plus overhead and profit.
Standard formula: charge 2.5–3.5× the employee's hourly rate for typical billable work.
- Engineer at $50/hour billable rate covers their salary.
- To cover all-in cost (1.35x): need $67/hour.
- To cover all-in cost + 30% margin: need $87/hour.
- To cover utilization losses (60% billable): need $145/hour.
Consultants at $200/hour aren't ripping you off — that's what it costs.
Hiring strategy implications
Knowing the multiplier helps with hiring decisions:
- "Can we afford this hire?" Salary × 1.35 is the realistic budget.
- "Is freelancing cheaper?" Yes if needed less than ~50% time.
- "Is offshoring profitable?" Maybe — but factor in time zone and management overhead.
The salary-vs-benefits tradeoff
For employees:
- $100k salary + $30k benefits = $130k total comp.
- $110k salary + $20k benefits = $130k total comp.
- Employees often value salary higher than equivalent benefits.
Many companies offer "flexible benefits" — choose between extra salary or richer benefits. Lets each employee optimize.
