Employee Cost Calculator
Base Salary Is the Smallest Number in the Real Cost of a Hire
Budget a new position at exactly its salary and the real cost will overrun that figure every time, because salary is only the starting point. Benefits, payroll taxes, and general overhead stack on top of it, and by the time they're all accounted for, the fully-loaded cost of an employee routinely runs well above the number printed on the offer letter.
The Formula
Load Factor = Fully-Loaded Cost ÷ Base Salary
Benefits and payroll taxes are calculated as percentages of base salary, while overhead is entered as a flat dollar figure — covering things like equipment, workspace, software licenses, and other costs that don't scale with salary the same way benefits typically do. The load factor expresses the whole result as a single multiplier on base salary, useful for quick comparisons across roles.
Why the Fully-Loaded Number Is the One That Matters
- Hiring budget accuracy — approving a position based on salary alone consistently underestimates the actual budget impact once benefits, taxes, and overhead are added.
- Build vs. contract comparisons — comparing a contractor's billed rate against an employee's fully-loaded cost, not just base salary, is the only apples-to-apples way to evaluate that staffing decision.
- Department cost allocation — charging departments for the true fully-loaded cost of their staff, rather than base salary, gives leadership an accurate picture of where labor spend is actually concentrated.
- Pricing and margin analysis — service-based businesses need fully-loaded labor cost, not salary, to correctly price work and understand true margins on billable time.
Example: A $60,000 Base Salary, Fully Loaded
| Component | Amount |
|---|---|
| Base Salary | $60,000.00 |
| Benefits (20%) | $12,000.00 |
| Payroll Taxes (7.65%) | $4,590.00 |
| Overhead | $3,000.00 |
| Fully-Loaded Cost | $79,590.00 |
Computed directly from the formula above; the resulting load factor here is 1.33x base salary. The 7.65% figure reflects the combined employer share of U.S. Social Security and Medicare payroll tax.
