You think that $100K employee costs $100K. Wrong.
When you hire someone at $100K salary, you're not adding $100K to your burn. You're adding $125K-$140K, maybe more. There's health insurance, retirement match, payroll taxes, equipment, office space, training, and tools. Most founders dramatically underestimate what an employee actually costs, then hire too fast and run out of cash. This calculator shows you the true all-in cost.
What This Calculator Does
This tool takes a base salary and layers on all the hidden costs of employment: benefits (health, dental, vision, 401k match), employer payroll taxes (FICA, unemployment insurance), equipment (laptop, monitor, phone), software tools, office space allocation, training, and overhead. The result is the fully loaded cost-what that employee truly costs your company monthly and annually.
How to Use This Calculator
Step 1: Enter the employee's base salary. If you're hiring a software engineer at $120K, enter 120000.
Step 2: Add benefits. Health insurance (employer cost) is typically $12K-$20K/year per employee depending on plan and location. Dental and vision are another $1.5K-$3K. Retirement match (401k) is often 3-6% of salary. Enter your company's benefits allocation.
Step 3: Calculate employer payroll taxes. Employer FICA (Social Security and Medicare) is 7.65% of salary. Unemployment insurance is another 1-2%. Most payroll providers calculate this automatically, but it's real money out of your pocket. Add about 10% to the salary for taxes.
Step 4: Estimate equipment and software costs. A laptop ($1.5K), monitor ($400), software licenses ($100-200/month), cell phone ($50-100/month). Annual cost is roughly $2K-$3K per employee depending on role.
Step 5: Add office and overhead. If you have office space, allocate rent, utilities, WiFi, kitchen, and facilities per person. If you're remote, cloud storage and collaboration tools. A fair allocation is $300-1000/month depending on whether you have physical office.
Step 6: The calculator shows total annual cost and monthly cost. Compare it to the base salary and be shocked.
The Formula Behind the Math
Basic Employee Cost Calculation
Total Cost = Salary + Benefits + Payroll Taxes + Equipment + Tools + Overhead
Breaking it down:
Cost as multiplier of base salary:
Cost Multiplier = Total Cost / Base Salary
Example: $144,700 / $100,000 = 1.447x. The employee costs 44.7% more than their base salary.
Monthly fully loaded cost:
Monthly Cost = Total Annual Cost / 12
Example: $144,700 / 12 = $12,058/month.
Our calculator does all of this instantly-but now you understand exactly what it's computing.
Startup Founders Making First Hires
You're solo and thinking about hiring your first engineer at $80K/year. You think "okay, burn increases by $80K." Wrong. Add 25% benefits, 10% payroll taxes, $2.5K equipment, $7.2K overhead. True cost is about $117K/year, or $9.75K/month. That's a 46% bump from the base salary. Your runway just got compressed significantly. This calculator makes that hit visible before you make the offer.
Series A Companies Expanding Teams
You raised $5M and you're in year two. You want to double your team from 5 to 10 people. You budget $500K for "salaries" and think you're golden. But true fully loaded cost for those five new hires is probably $700K-$750K. Now your burn increases faster than you planned. This calculator prevents that surprise mid-year when you run out of cash.
Finance Leaders Building Headcount Plans
You're forecasting hires for the next 18 months and need to model the cash impact. With this calculator, you can show the true all-in cost of each hire. When the board asks "can we afford five more engineers next quarter?", you have a number: $50K-$60K/month depending on seniority and benefits. That feeds directly into runway and cash forecasting.
Operators Deciding Between Hiring and Freelancing
You need a contractor for a three-month project. The freelancer charges $8K/month. An employee doing the same work costs $12K+/month all-in, and you have ongoing commitment. If this is truly a short-term need, freelancing is cheaper. But if this becomes a permanent role, hiring the employee is better long-term. This calculator helps you see the break-even point.
Tips and Things to Watch Out For
Benefits vary by location and company stage. Early-stage startups often can't afford fancy benefits. A $100K employee at a startup might have $50K in benefits while the same employee at a large company has $35K. Know what you're offering and be realistic about the cost.
Taxes and benefits are not optional. You cannot skip payroll taxes to save money. You cannot avoid employer-paid health insurance costs. These are real costs that come out of your cash. Don't pretend they don't exist when budgeting.
Equipment should match the role. A designer needs a better computer ($3K) than a customer support rep ($1.2K). A salesperson might need a phone and CRM tools ($200+/month) while a designer doesn't. Customize equipment costs by role rather than averaging.
Overhead allocation matters at scale. If you have a $50K/month office rent and 10 employees, that's $5K per employee per month in overhead. If you have 50 employees, it's $1K per employee per month. As you scale, overhead allocation per employee shrinks, which improves your unit economics. This is one reason big companies can afford to pay the same salary at lower fully loaded cost.
Don't forget training and onboarding. A new employee typically takes 2-3 months to become fully productive. During that time, you're paying for training, onboarding, and mentorship from existing staff. Add 5-10% to the first-year cost of every new hire to account for ramp time.
International hires have different costs. Hiring in the Philippines or Eastern Europe has much lower salary and benefit costs but adds complexity (payroll processing, tax compliance, time zone coordination). Use this calculator with localized costs if you're hiring globally.
Total cost per employee improves with scale. Your first five employees have the highest fully loaded cost (office overhead spreads thin). Your 50th employee has a lower fully loaded cost (overhead allocates across more people). This is why businesses can scale labor costs more efficiently as they grow.

Frequently Asked Questions
What percentage should benefits be of salary?
Typically 20-30% for startups, 25-35% for established companies. Health insurance is the big cost (typically 50-70% of benefits spend). The rest goes to retirement, dental, vision, HSA, and other perks. Talk to your payroll provider or insurance broker to get actual quotes for your team.
Are payroll taxes really 10% on top of salary?
About 7.65% is employer FICA (Social Security and Medicare), plus 1-2% for unemployment insurance, state disability, and state-specific taxes. So yes, roughly 10% is a good estimate. Different states have different rules, so check with your payroll provider.
Should I include my own founder salary in cost calculations?
Yes. Even if you're not paying yourself, you should include a market-rate salary for your role in your cost calculations. This tells you the true cost of the business and prevents you from making decisions that only work because you're not being paid.
Does outsourcing to freelancers really save money?
Depends on the duration. For short-term projects (under six months), freelancers are cheaper because you avoid benefits and overhead. For ongoing work (over 18 months), a full-time employee usually becomes cheaper and gives you better alignment and productivity. Use this calculator to compute the break-even point for your specific numbers.
What if I provide cheap or no benefits?
You might reduce cost by 15-20%, but you'll struggle to attract and retain talent. Good engineers and designers expect competitive benefits. Startups typically offer lower salaries in exchange for equity, but benefits are table stakes. Cutting benefits is penny-wise and pound-foolish.
How do I reduce employee cost without cutting headcount?
Reduce overhead allocation (move to cheaper office or remote), negotiate better health insurance rates, offer equity instead of some cash compensation, or hire more junior people with lower salaries. But the biggest leverage is growth-if you grow revenue 50% but headcount only grows 30%, you're improving cost efficiency.
Should I count equity as part of employee cost?
Not in this calculator, but yes in your overall cost. A $80K employee with $100K in equity (vesting over four years) costs you more than $80K. Include equity value when evaluating total employee cost, but it doesn't impact your cash burn. This calculator focuses on cash cost.
