The salary you write on an offer letter is rarely the amount that actually leaves your bank account. A $80,000 base salary usually costs a business closer to $112,000 once employer payroll taxes, health benefits, a 401(k) match, paid time off, and workers' compensation are stacked on top. That gap — often called the loaded cost, burdened cost, or fully-loaded cost of labor — is the single most under-budgeted number in small business hiring.
This employee cost calculator adds every employer-borne percentage onto the base salary and gives you the true annual (and monthly) cost of a hire. Slide the inputs and watch the loaded-cost multiplier move: it shows you, in one number, how many cents of extra cost you pay on top of every dollar of salary.
How to Use
- Enter the Annual Base Salary — the gross cash pay promised in the offer letter, before any withholdings. This is the foundation the rest of the load is calculated against.
- Set the Employer Payroll Tax rate. The default of 7.65% is the standard US employer share of FICA: 6.2% Social Security on wages up to the annual wage base, plus 1.45% Medicare with no cap. Change it only if you have a special exemption.
- Type your Benefits Load as a percent of salary. This bundles employer-paid health insurance, 401(k) match, dental/vision, life insurance, and the cost of paid time off. A common band is 25%–40%; 30% is a safe default.
- Set the Workers' Compensation rate. Premiums vary wildly by risk class — office staff might be 0.5%, while roofing or delivery can exceed 5%. Leave it at 2% as a middle estimate if you do not know your code.
- Read the result card. It breaks out each cost line, shows the Loaded Cost Multiplier (for example 1.40×), and gives you both the total annual loaded cost and the monthly figure.
The loaded multiplier is the number to remember: a 1.40× multiplier means every $1 of base salary costs the company about $1.40 in total.
The Loaded Cost Formula
This calculator uses the standard employer-burden formula used by HR departments and payroll providers:
Total Loaded Cost = Base Salary × (1 + payrollTax% + benefits% + workersComp%)
Each line is a percentage of base salary, so they add together into a single multiplier. On a $80,000 salary at the defaults:
- Employer payroll tax: 7.65% × $80,000 = $6,120
- Benefits load: 30% × $80,000 = $24,000
- Workers' comp: 2% × $80,000 = $1,600
- Total loaded cost = $80,000 × 1.3965 = $111,720
That is a $31,720 burden on top of the advertised salary — roughly a 40% uplift. Budgeting off the $80,000 figure alone would understate the real cost of the role by nearly a third.
What Each Line Actually Covers
- Employer Payroll Tax (7.65%) — The employer's half of FICA. Social Security is 6.2% on wages up to the annual wage-base cap; Medicare is 1.45% uncapped. On top of this, most employers also pay FUTA (6% on the first $7,000, usually reduced to 0.6% after SUTA credits) and state unemployment (SUTA), which this model lets you fold into the payroll-tax line if you wish.
- Benefits Load (often 25%–40%) — The largest lever after salary itself. Employer-paid health premiums alone commonly run $6,000–$12,000 per employee per year; a 3%–6% 401(k) match and accrued PTO push the total higher.
- Workers' Compensation (0.5%–5%) — A state-based insurance premium tied to your industry's injury history (experience modifier). Desk jobs are cheap; physically risky trades are not.
Use the monthly loaded cost to price roles against revenue: if a new hire must generate billings, a rough rule of thumb is that a productive employee should return at least 1.25×–1.5× their loaded cost to the business.
Examples
Example 1 — The default hire. You offer a mid-level role at $80,000, with a standard 7.65% payroll tax, a 30% benefits load, and 2% workers' comp. The calculator shows payroll tax of $6,120, benefits of $24,000, and comp of $1,600, for a total loaded cost of $111,720 — about $9,310 per month. The multiplier is 1.40×.
Example 2 — A lean benefits package. A startup offers $90,000 but keeps benefits light at 15% (a 3% 401(k) match, a subsidized but not free health plan), with the same 7.65% tax and 2% comp. The factor is 1 + 0.0765 + 0.15 + 0.02 = 1.2465×, and the loaded cost is $112,185 — still over $112,000 even though benefits are half the default.
Example 3 — A six-figure executive. For a $1,000,000 executive role at the same 7.65% / 30% / 2% load, the multiplier holds at 1.3965× and the total loaded cost is $1,396,500 per year — roughly $116,375 per month. High salaries scale linearly with the burden, so a 10% raise moves the loaded cost by nearly 14%.
FAQ
How much does an employee actually cost on top of salary?
For most US employers the loaded cost is about 1.25× to 1.40× base salary. On an $80,000 salary that is roughly $100,000–$112,000 per year. The extra comes mainly from employer payroll taxes (7.65%), benefits (25%–40%), and workers' compensation (0.5%–5%).
What is the employer share of payroll tax?
The standard employer FICA contribution is 7.65%: 6.2% for Social Security on wages up to the annual wage-base cap, plus 1.45% for Medicare with no upper limit. Most employers also owe federal (FUTA) and state (SUTA) unemployment tax, which is small but should be added to the payroll-tax line.
Why is the benefits load so high?
Because it bundles several recurring costs: employer-paid health, dental and vision premiums, a 401(k) or pension match, short- and long-term disability, life insurance, and the cost of accrued paid time off. Health premiums alone often run thousands of dollars a year per employee, which is why a 30% load is typical rather than generous.
What is a good loaded-cost multiplier?
A multiplier near 1.25×–1.30× is lean (modest benefits, low-risk workers' comp). 1.35×–1.40× is typical for a full-benefits US role. Anything above 1.50× usually signals rich benefits, a high-risk industry, or heavy unemployment-tax exposure — worth scrutinizing before you approve the headcount.
Do contractors cost less than employees?
Often yes on paper, because a 1099 contractor does not trigger employer FICA, workers' comp, or benefits load. However, misclassifying a worker as a contractor when they should be an employee carries back-pay and penalty risk. Use this calculator to price the W-2 baseline, then compare the contractor quote against the loaded employee figure rather than the base salary.
How do I budget payroll for a new hire?
Take the monthly loaded cost, not the monthly salary. If a role's total loaded cost is $9,310 per month, budget that number — not $6,667 — when you model cash flow, and remember payroll taxes and benefits recur every paycheck whether revenue arrives or not.
