New founders almost always make the same budgeting mistake: they see a $70,000 salary and set aside $70,000. Then the first payroll run happens, benefits kick in, and the real number turns out to be closer to $95,000. Nobody hides this — it's just spread across enough line items that it's easy to underestimate until you've actually hired someone.
Beyond the Salary Number
Salary is just the starting point of employee cost. Employers must also pay: mandatory payroll taxes, health and dental insurance contributions, 401(k) match, paid time off (PTO), paid holidays, workers' compensation insurance, and indirect costs like equipment, software, office space, and management time. The gap between salary and true cost is significant — and often underestimated.
Mandatory Employer Payroll Taxes
US employers pay these mandatory taxes on top of every employee's salary: Social Security (6.2%) on wages up to $184,500 (2026, up from $176,100 in 2025), Medicare (1.45%) with no cap (plus 0.9% additional on wages over $200K, employee-paid only), FUTA (Federal Unemployment, 0.6-6% on first $7,000), and SUTA (State Unemployment, varies by state — typically 1-5%). Total mandatory employer taxes: approximately 8-12% of salary.
| Tax | Employer Rate | On $70K Salary |
|---|---|---|
| Social Security | 6.20% | $4,340 |
| Medicare | 1.45% | $1,015 |
| FUTA | ~0.60% | $42 |
| SUTA (avg) | ~2.70% | $189 |
| Total Employer Taxes | ~10.95% | $5,586 |
Benefits Cost Breakdown
Voluntary (but competitive necessity) benefits add significant cost: Health insurance: employer typically contributes $6,000-$16,000/year for individual coverage; $15,000-$30,000 for family. 401(k) match: 3-6% of salary ($2,100-$4,200 on $70K). Dental/vision: $500-$2,000/year. PTO: 15 days = $4,038 on a $70K salary. Paid holidays: 10 days standard = $2,692 on $70K. Benefits typically add $15,000-$35,000/year on a $70,000 salary.
Indirect Overhead Costs
True cost also includes: Equipment (computer, monitors, peripherals: $1,500-$3,000 upfront, ~$500-$800/year amortized), software licenses ($500-$2,000/year per person), office space ($5,000-$20,000/year per person in leased space, less for remote), HR and recruiting (recruiting cost is typically 15-25% of first-year salary), and management overhead (~10-20% of employee time from managers).
The 1.25-1.4x Employer Cost Multiplier
The widely-used rule of thumb: total employee cost = 1.25-1.4× base salary. A $70,000 salary employee costs approximately $87,500-$98,000 all-in. For remote employees (no office space cost), the lower end of the range applies. For on-site employees with full benefits in high-cost areas, the upper end — sometimes exceeding 1.5x. Use this multiplier for rapid budgeting, then refine with actual benefit costs.
💡 For startups and small businesses: the 1.4x rule helps with pricing — if you bill a client $150/hour, your fully-loaded $70K employee ($87,500/year ÷ 2,000 hours) costs $43.75/hour, leaving $106.25 for overhead and profit.
Quick Checklist
- Use the 1.3x multiplier for quick headcount budget estimates
- Calculate fully-loaded cost before approving any new hire
- Include recruiting cost (15-25% of first-year salary) in hiring budget
- Compare contractor vs employee cost using fully-loaded numbers
- Track actual benefit costs annually — they typically increase 3-8% per year
- Include equipment and software in first-year total hiring cost
