Employee Cost Calculator: What a Hire Really Costs

The salary on an offer letter is never the full cost of an employee. Payroll taxes, benefits, retirement contributions and the equipment and software they use all add up, typically pushing the real number well above the base salary alone.

What the cost multiplier actually tells you

A common rule of thumb puts the fully-loaded cost of an employee at 1.25x to 1.4x their base salary, though it varies a lot by how generous your benefits are and how much overhead you allocate per head. The multiplier this calculator shows is specific to the numbers you entered, not a generic industry average.

Knowing your real multiplier matters most when you're deciding between hiring and other options, like a contractor, a raise for an existing employee, or new tooling that removes the need for the role entirely.

What people usually forget to include

Employer-side payroll tax, which in the US includes the employer's share of Social Security and Medicare, is easy to overlook since it never shows up on the employee's own pay stub. Retirement matching and the ongoing cost of benefits like health insurance are the next most commonly underestimated line items.

Overhead, a laptop, software licenses, a share of office rent or a home-office stipend, is smaller individually but adds up across a growing team and is worth estimating honestly rather than leaving out entirely.

Using this number when you're deciding to hire

Compare the true annual cost against the revenue or time savings you expect the role to generate, not just the salary line in your budget. A role that looks affordable at its salary alone can look very different once the full multiplier is applied.

This calculator doesn't include one-time costs like recruiting fees or onboarding time, which are real but separate from the ongoing annual cost of keeping someone employed.
