Employee Cost Calculator

When budgeting for a new hire, the advertised salary is just the starting point. Health insurance alone averages $8,435 for single coverage and $23,968 for family coverage annually (2024 KFF Employer Health Benefits Survey), with employers typically paying 70–85% of those premiums. Add payroll taxes at 7.65–10% (employer FICA at 7.65% plus FUTA at 0.6% after state credit plus SUTA at 1–5% depending on state), retirement matching at 3–6% of salary (median employer contribution per Vanguard's How America Saves report), workers' compensation insurance (0.3–3% by industry, much higher for hazardous work), and overhead costs for workspace, equipment, and administrative support.

For a typical US office employee earning $75,000, the add-ons commonly stack to $25,000–$35,000 beyond base salary: roughly $15,000 in health and retirement benefits, $7,000–$9,000 in payroll taxes, $500–$2,000 in workers' comp, and $3,000–$8,000 in allocated overhead. That produces a total employer cost of $100,000–$110,000 — a 1.33×–1.47× burden multiplier. Getting this math right matters because headcount is typically the single largest cost center in any knowledge-work business, and systematically understating employer cost by 20–30% through naïve salary-only planning is one of the most common cash-flow mistakes in early-stage companies.

Workers' comp rates vary dramatically by industry risk class, from 0.3–0.5% of payroll for office and professional workers to 5–15% for construction, roofing, and manufacturing. State insurance rating bureaus (NCCI for most states, California's WCIRB for California, independent bureaus in NY/NJ/PA) publish class codes and base rates that categorize each job function by injury risk. A company with a mix of office workers and field technicians pays blended rates that average across both groups, and misclassifying employees into lower-risk codes is a common audit finding that produces retroactive premium bills plus penalties.

Your Experience Modification Rate (EMR) adjusts your base rate based on your actual claims history over the previous three years. An EMR of 1.0 means you pay the class code base rate exactly; above 1.0 you pay more (worse-than-average claims); below 1.0 you pay less (better-than-average claims). A strong safety record with EMR of 0.75 reduces costs by 25%, while a company with EMR of 1.25 pays 25% more than base rate. Over 3–5 years, investing in safety programs, return-to-work programs, and proactive claims management can move EMR from 1.0 to 0.70, saving 30% of workers' comp costs indefinitely. For high-risk industries, this represents 1–4% of total payroll and is one of the highest-ROI risk-management investments available to employers.

Contractors often seem expensive at $75–$150/hour sticker rates, but the honest comparison is against true FTE cost per productive hour, not against base salary. At $65,000 base salary with a 1.40× burden multiplier, your FTE costs $91,000/year; dividing by 2,080 annual hours minus 120 PTO hours yields $46/productive hour. A contractor billing $75/hour for 40 hours/week across 48 weeks costs $144,000 in year 1 — significantly more than the FTE — but with zero benefits, no payroll taxes, no workers' comp, no long-term commitment, and no severance obligation if the project ends.

The crossover point depends on consistency of need (full-time ongoing work favors FTE; variable-demand or project-specific work favors contractor), training investment (contractors work for multiple clients so knowledge walks out the door; FTEs build institutional knowledge), IP and loyalty considerations (contractors often retain IP rights unless contracts explicitly transfer ownership), and legal classification risk (misclassifying a contractor who should be an employee exposes the employer to back FICA, penalties, and state-level claims). For predictable full-time roles continuing 18+ months, FTEs are almost always cheaper on a blended cost-per-outcome basis. For 3–12 month projects or specialized skills needed occasionally, contractors are typically better. Use the Headcount Planner tab to model specific scenarios with your actual burden rate.

Cost-management strategies that preserve compensation signal and employee satisfaction include: offering high-deductible health plans paired with employer-funded HSAs (typically saves 10–20% on premiums while giving employees a tax-advantaged savings vehicle), shifting to remote or hybrid work to reduce office overhead ($3,000–$8,000/employee/year in facilities cost plus higher retention from remote flexibility), professional-development stipends ($2,000–$5,000/year) that often produce better outcomes than mandatory external training at a fraction of the cost, and unlimited or generous PTO policies that surprisingly reduce average days taken while improving recruitment.

The highest-ROI cost management investment is retention, not compensation reduction. Replacing an employee costs $15,000–$25,000 for frontline roles and $50,000–$200,000 for senior professional roles when you account for recruiting fees, onboarding time, lost productivity, and knowledge loss — SHRM research puts the total at 50–200% of annual salary depending on role level. Reducing turnover from 20% to 15% in a 100-person company saves $75,000–$125,000 annually at the low end, far more than equivalent compensation cuts would save in visible salary expense. Practical retention investments include competitive compensation benchmarking (prevents silent underpayment that drives resignations), career development programs, flexible work arrangements, manager-training programs (bad managers are the #1 cause of voluntary turnover per Gallup research), and stay-interview programs that catch concerns before they become resignation letters.
