What a New Hire Actually Costs a Small Business

When you hire someone at $18 an hour, you don't pay $18 an hour. You pay closer to $21 or $22, and if you add health insurance, it can reach $25 or more. Most small business owners figure this out on their first payroll run, when the total looks bigger than what they expected.

This post walks through every cost so you can budget accurately before you make your next hire.

The baseline number

The U.S. Small Business Administration estimates that a worker's true cost to the employer is 1.25 to 1.40 times their base wage. For a $40,000 salary, that means you're spending $50,000 to $56,000 all-in.

That multiplier comes from a stack of costs that don't appear in the wage you agree on with the applicant. Let's go through each layer.

Federal payroll taxes

The moment you run payroll, you owe the federal government a cut on top of the wages you pay.

FICA (Social Security and Medicare):

Employers pay 6.2% for Social Security on wages up to $176,100 per employee in 2026, plus 1.45% for Medicare on all wages. That's 7.65% of every paycheck.

For a worker earning $20/hr full-time (about $41,600/year), that's roughly $3,182 in FICA taxes that comes out of your pocket, not theirs.

FUTA (Federal Unemployment Tax):

This is 6% on the first $7,000 of wages, but most employers pay only 0.6% after taking the standard credit for paying state unemployment taxes. That works out to $42 per employee per year. Small, but real.

California-specific employer costs

California adds its own layer. Every business in Orange County, the Inland Empire, and everywhere else in the state pays these on top of federal taxes.

State Unemployment Insurance (SUI):

New employers pay 3.4% on the first $7,000 of wages per employee per year. That's $238 per employee annually. Once you've been operating for a few years, your rate can drop as low as 1.5% or climb as high as 6.2%, depending on how many former employees have filed unemployment claims against you.

If you're dealing with frequent turnover, this rate creeps up and becomes a real cost. The California EDD publishes the current rate schedules.

Employment Training Tax (ETT):

0.1% on the first $7,000 per employee per year. That's $7 per person. Barely noticeable, but worth knowing it exists.

Workers' Compensation Insurance:

Not a tax, but required by California law. Rates depend on your industry and claims history. For most retail, restaurant, and service jobs, expect 1.5% to 4% of total payroll.

A cafe owner in Huntington Beach we spoke with was running about 2.2% for front-of-house staff. On a $35,000 salary, that's $770 per employee per year. Multiply it by five people and it's nearly $4,000 you didn't have a line item for.

If you've ever had a workplace injury claim filed against you, your rate goes up. Taking care of workplace safety is an actual financial issue, not just a compliance checkbox.

Mandated benefits

California requires a few things that add real dollars to your per-employee cost, even if you're not offering anything optional.

Paid Sick Leave:

California requires at least 5 days (40 hours) of paid sick leave per year. For a $20/hr worker, that's $800 in paid time that doesn't produce revenue. For a part-time worker at fewer hours, the accrual is prorated, but the obligation is still there.

This isn't optional and it doesn't matter how small your business is. One employee means you owe paid sick leave.

ACA Health Coverage:

If you have 50 or more full-time equivalent employees, you're required to offer health coverage under the Affordable Care Act. Most small businesses hiring hourly workers stay well under that threshold. But if you're growing toward 30 or 40 employees, start running the numbers before you cross the line.

If you do offer health insurance to attract better candidates, which makes sense in a competitive market like Orange County, individual premiums typically run $400 to $600 per employee per month. That's $4,800 to $7,200 per year per person.

For a breakdown of which benefits actually move the needle for hourly workers without breaking the bank, see Affordable Employee Benefits for Hourly Workers.

One-time hiring costs

Every new hire comes with upfront costs that never show up on a pay stub but absolutely come out of your pocket.

Recruiting:

Job board postings on Indeed or ZipRecruiter typically run $200 to $400 per listing, and you may run several before finding the right person. Staffing agencies charge 15% to 25% of first-year wages as a placement fee.

Some small businesses use tools that skip the per-listing fee entirely. My Friendly Staff puts a phone number on your help wanted sign and has an AI interview callers 24/7 in English or Spanish, ranking each applicant in a dashboard by fit. For businesses that hire regularly, that keeps recruiting costs predictable and avoids surprise per-posting bills. See Where to Post Jobs for Hourly Workers for a comparison of what's worth paying for.

Onboarding and Training:

Getting a new hire to full productivity typically takes 10 to 40 hours of someone else's time, whether that's yours or a senior employee's. At $25 to $40 an hour in management time, that's $250 to $1,600 per new hire.

Most owners undercount this one. For a practical framework on doing it efficiently, see How to Onboard a New Employee at Your Small Business.

Uniforms and Supplies:

Depending on your business, figure $75 to $300 for uniforms, safety gear, branded clothing, or tools you supply at hire.

The worked example

Let's put it all together. A full-time front-of-house worker at a restaurant or retail shop in Orange County, hired at $20/hr, working 38 hours a week.

Annual wages: $39,520

Employer payroll taxes:

• FICA (7.65%): $3,023
• FUTA (0.6% on first $7k): $42
• CA SUI (3.4% on first $7k, new employer): $238
• CA ETT (0.1% on first $7k): $7

Workers' comp at 2.2%: $869

CA paid sick leave (40 hours at $20/hr): $800

One-time costs amortized over one year:

• Recruiting: $350
• Onboarding and training time: $600
• Uniforms and supplies: $150

Total first-year cost: approximately $45,599

You're paying $20/hr but spending effectively around $23/hr all-in. That's a 15% premium over wages with no health insurance included. Add a basic health contribution and you're closer to $27 to $28 per hour in real cost.

What surprises owners

A few things trip up people doing this math for the first time.

Workers' comp audits. Your rate is an estimate paid throughout the year. At the end of the policy period, your insurer audits actual payroll and adjusts. If you ran more overtime than expected, the bill goes up. This catches a lot of owners off guard in December.

Overtime. California overtime kicks in after 8 hours in a single day, not just 40 hours in a week. If employees are regularly hitting 8.5 or 9-hour shifts, you're paying 1.5x wages on those extra hours and it compounds fast. See California Overtime Law for the full breakdown.

SUI rate creep. New employers start at 3.4%, but if former employees file multiple unemployment claims, your rate climbs. Some experienced employers pay 5% or 6%. That adds $200 to $350 per employee per year on top of everything else.

Turnover multiplier. Every time someone quits and you hire again, you restart the clock on recruiting, training, and one-time costs. At $1,000 to $2,000 per hire for a frontline worker, high turnover can quietly add $5,000 to $10,000 a year in hidden costs. For strategies that actually cut that number, see How to Reduce Employee Turnover at Your Small Business.

Why this number matters

Once you know your true per-employee cost, two decisions get a lot clearer.

Pricing. If you run a service business, you need the fully-loaded cost of labor before you quote a job. A lot of operators price based on hourly wage and wonder why margins are tighter than expected. The workers' comp, taxes, and paid leave you forgot to include are part of the reason.

Hiring decisions. Many owners wait too long to hire because they're scared of the wage number. But they're not counting what understaffing costs: missed sales, bad customer experience, their own burnout. The true cost of hiring is real. So is the true cost of not hiring.

If you're thinking through that calculation, the cost of a bad hire breakdown shows how the math gets worse when you hire the wrong person and have to start over. And the labor cost percentage guide shows how to track your total labor spending weekly so a problem shows up in your spreadsheet before it shows up in your bank account.

The short version

• Expect to spend 1.15x to 1.40x the base wage per employee all-in
• In California, workers' comp and SUI add meaningful cost on top of federal taxes
• Paid sick leave is mandatory and costs 40 hours of wages per year per employee
• Recruiting and onboarding add $1,000 to $2,000 per hire in one-time costs
• Every time someone leaves, you pay those one-time costs again
• Know your fully-loaded cost before you price your services or decide whether to hire

The number is not meant to scare you off. It's meant to help you budget honestly and build a business that can actually afford to keep good people.
