QuickBooks offers a free employee cost calculator as one of its hiring resources — a genuinely useful tool for estimating what a new hire really costs, positioned as a lead-in to QuickBooks' payroll and accounting products.
The core insight both tools are built around is the same, and it's one every hiring manager should internalize: the real cost of an employee typically runs 1.25 to 1.4 times their base salary once you account for employer payroll taxes, benefits, and overhead — so a $50,000 salary can mean $62,500-$70,000 in actual cost to the business, not $50,000.
A large piece of that gap is a specific, fixed number worth knowing directly: the employer share of FICA payroll tax is 7.65% of wages (6.2% Social Security up to the annual wage base, plus 1.45% Medicare) — a cost that applies to every employee, every paycheck, regardless of state or industry.
QuickBooks' calculator is a genuinely useful hiring cost estimator for small business, and if you're already running payroll through QuickBooks, staying in that ecosystem for the estimate keeps things connected. SMBkits' employee cost calculator does the same total-compensation math — wage, taxes, benefits, overhead — as a standalone tool with no account and no payroll platform attached.
Either way, the number that matters before extending an offer is the fully loaded cost, not the salary line alone. Budgeting a hire off salary and then discovering the real monthly cost once taxes and benefits land is a common and avoidable surprise — running the calculation first, with either tool, prevents it.
| Feature | SMBkits | QuickBooks |
|---|---|---|
| Includes payroll tax (FICA) | Yes | Yes |
| Includes benefits & overhead | Yes, configurable | Yes |
| Account required | No | No, for the calculator |
| Connected to payroll software | No | Yes — QuickBooks Payroll |
Employer payroll taxes (including the 7.65% FICA share), benefits (health insurance, retirement matching), workers' comp insurance, and any equipment or software the role requires — these commonly add 25-40% on top of salary alone.
It's easy to budget for a hire based on salary alone and get blindsided by the real monthly cost once taxes and benefits are added. Knowing the fully loaded number upfront prevents that surprise.
It's a widely used planning benchmark, not a precise figure — your actual multiplier depends on your specific benefits package, state payroll taxes, and any role-specific costs like equipment or licensing, so treat it as a starting estimate.
