The True Cost of an In-House Employee vs. a Virtual Assistant
When businesses compare the cost of a virtual assistant against an in-house hire, they almost always start with the wrong number. Base salary is visible. The loaded cost is not—and the gap between the two is where the real savings argument lives.
According to the U.S. Bureau of Labor Statistics 2024 Employer Costs for Employee Compensation report, benefits and employer-paid taxes add an average of 31.8% to base wages for civilian workers. For a $50,000 administrative employee, that means the real cost to the employer is closer to $65,900 before factoring in office space, equipment, training, and management overhead.
Virtual assistants eliminate almost all of those secondary costs by definition. They work remotely, supply their own equipment, operate independently, and are typically engaged as contractors or through staffing agencies—meaning no employer payroll taxes, no benefits liability, and no overhead allocation.
What to Include in a VA Cost Savings Calculator
A complete cost savings model has two sides: what you currently pay (or would pay) for in-house support, and what you pay for VA support. The difference is your savings.
In-House Cost Inputs:
- Base annual salary or hourly rate
- Employer payroll taxes (Social Security 6.2%, Medicare 1.45%, FUTA/SUTA approximately 1–3%)
- Health insurance employer contribution (national average: $7,911/year for single coverage per KFF 2023 Employer Health Benefits Survey)
- Paid time off (average 15 days = 6% of annual hours)
- Office space per employee (average $8,000–$12,000/year for commercial office in mid-tier U.S. markets per CBRE 2023 data)
- Equipment and IT support ($1,500–$3,000/year)
- Recruiting and onboarding costs ($4,000–$7,000 for administrative roles per SHRM)
VA Cost Inputs:
- Hourly rate or monthly retainer
- Any agency placement fee (if applicable)
- Onboarding time cost (typically 2–4 weeks at reduced output)
- Software licenses or tool access you provide
Running the Numbers: A Sample Calculation
Consider a business replacing a part-time, 20-hour-per-week in-house administrative assistant earning $22/hour in a mid-sized U.S. city.
Annual in-house cost:
- Base wages: $22,880
- Payroll taxes (7.65%): $1,750
- Pro-rated benefits (50%): $3,956
- Office allocation (50%): $4,000–$6,000
- IT/equipment (50%): $750–$1,500
- Total: $33,336–$36,086
Annual VA cost at $15/hour, 20 hours/week:
- VA wages: $15,600
- No payroll taxes, no benefits, no office overhead
- Agency fee (if applicable): $0–$2,000
- Total: $15,600–$17,600
Annual savings: $15,736–$20,486, a savings rate of approximately 47–57% depending on the specific inputs.
This calculation is consistent with findings from the National Federation of Independent Business 2024 Small Business Survey, which reported that 68% of small businesses using virtual assistants cited cost reduction as the primary measurable benefit, with average reported savings of $11,000–$22,000 annually per VA position.
Hidden Savings That Most Calculators Miss
Beyond the direct labor cost differential, several secondary savings categories rarely make it into initial cost models:
Turnover avoidance: The average cost to replace an administrative employee runs 50–200% of annual salary (Work Institute, 2023 Retention Report). VA arrangements with established agencies reduce turnover risk substantially.
Overtime elimination: In-house employees generate overtime liability during peak periods. VAs absorb volume spikes without premium pay.
Benefits administration overhead: HR management time for benefits, compliance, and payroll for each additional in-house employee has real cost—typically 15–20 minutes per employee per week at HR rates.
Real estate optimization: Companies that replace in-house roles with VAs can reduce leased square footage, generating compounding savings especially in high-cost markets.
Using the Calculator to Make the Hiring Decision
The cost savings calculation should answer one question: at what engagement level does a VA generate net savings compared to the current alternative? For most businesses, the answer is "immediately"—but the magnitude of savings scales with how accurately you've modeled your in-house costs.
Businesses that want to apply these numbers to their specific situation can explore structured VA solutions through Stealth Agents, which offers transparent pricing that makes the cost savings calculation straightforward.
Undercounting hidden in-house costs is the most common reason businesses underestimate VA value. Running the full model—not just the hourly rate comparison—almost always strengthens the case for making the switch.
