The Complete Guide to the True Cost of an Employee
By Arshi Khan, Founder of Just4Marketing · Last reviewed October 2026
An employee's salary is only part of what they cost. Employer payroll taxes, health insurance, retirement contributions, equipment, and software all add up, and paid time off means the cost is spread over fewer working hours. This guide shows how to estimate the full cost so you can budget a hire or compare it with a contractor.
What goes into the total
True cost = salary + employer payroll taxes + benefits + retirement match + equipment, software, and training. Cost per worked hour = true cost ÷ (2,080 − paid time-off hours).
In the calculator's example, a $70,000 salary costs about $93,155 a year in total — 1.33× salary — or $47.53 per hour actually worked, compared with $33.65 from salary alone.
How the multiple changes with salary
| Salary | Estimated true cost | Multiple |
|---|---|---|
| $50,000 | $70,825 | 1.42× |
| $70,000 | $93,155 | 1.33× |
| $100,000 | $126,650 | 1.27× |
Assumes 7.65% payroll taxes, a 4% retirement match, $12,000 of benefits, and $3,000 of equipment and software per year.
Costs that are easy to miss
Recruiting and onboarding
Agency fees, job ads, and the months before a new hire is fully productive add a one-time cost.
Office space
Desks, rent, and utilities for in-office staff are often several thousand dollars per person per year.
Insurance and compliance
Workers' compensation, payroll software, and HR services scale with headcount.
Frequently asked questions
How much does an employee cost on top of salary?
In the U.S., a common rule of thumb is 1.25 to 1.4 times salary once taxes and benefits are included. The multiple is usually higher for lower salaries, because benefits like health insurance cost about the same regardless of pay.
What employer payroll taxes are there in the U.S.?
Employers pay 7.65% of wages for Social Security and Medicare (6.2% Social Security up to the annual wage base, plus 1.45% Medicare), plus federal and state unemployment taxes. Rates and wage bases change yearly and vary by state, so check current figures. Other countries have different systems — enter your own rate.
Why does paid time off raise the hourly cost?
A full-time year is about 2,080 hours, but holidays, vacation, and sick days aren't worked. With 120 hours of paid time off, the year's cost is spread over 1,960 working hours, so each worked hour costs more.
Should I compare this with a contractor's rate?
Yes — compare a contractor's hourly rate with the employee's cost per hour actually worked, not with salary ÷ 2,080. Contractors usually charge more per hour because they cover their own taxes, benefits, and downtime.
