Gusto Payroll Calculator
Managing payroll is one of the most important — and expensive — responsibilities for any business owner. Whether you run a small startup or a growing company, understanding your true payroll costs goes far beyond simply multiplying salary by the number of employees.
That’s where our Gusto Payroll Calculator comes in.
This powerful, easy-to-use online tool helps you estimate:
- Gross payroll per pay period
- Employer FICA taxes (7.65%)
- Employer state payroll taxes
- Monthly payroll expenses

Why Payroll Cost Calculation Is So Important
Many employers underestimate the real cost of hiring employees. Salary is only part of the equation.
As an employer, you are responsible for:
- Paying the employee’s salary
- Covering employer FICA taxes
- Paying state employer taxes
- Funding employee benefits
- Paying payroll software fees
These expenses add up quickly. Without accurate forecasting, payroll can strain cash flow and reduce profitability.
Our calculator helps you see the complete financial picture before making hiring or budgeting decisions.

Example Payroll Calculation
Let’s walk through a realistic example.
Number of Employees: 5
Average Salary: $60,000
Payroll Frequency: Bi-Weekly
State Tax Rate: 5%
Benefits: $400 per employee/month
Gusto Base Fee: $39/month
Per Employee Fee: $6/month
Step 1: Annual Gross Payroll
5 × $60,000 = $300,000
Step 2: Per Payroll Period (Bi-Weekly = 26 periods)
$300,000 ÷ 26 = $11,538.46 per payroll
Employer FICA (7.65%):
$11,538.46 × 7.65% = $882.69
State tax (5%):
$11,538.46 × 5% = $576.92
Total per payroll period:
$11,538.46 + $882.69 + $576.92 = $12,998.07
Step 3: Monthly Breakdown
Monthly Gross Payroll:
$300,000 ÷ 12 = $25,000
Monthly FICA (7.65%):
$25,000 × 7.65% = $1,912.50
Monthly State Tax (5%):
$25,000 × 5% = $1,250
Total Monthly Taxes:
$3,162.50
Monthly Benefits:
5 × $400 = $2,000
Monthly Gusto Fees:
$39 + (5 × $6) = $69
Total Monthly Payroll Cost:
$25,000 + $3,162.50 + $2,000 + $69 = $30,231.50
Step 4: Annual Employer Cost
Annual Taxes:
$3,162.50 × 12 = $37,950
Annual Benefits:
$2,000 × 12 = $24,000
Annual Gusto Fees:
$69 × 12 = $828
Total Annual Payroll Cost:
$300,000 + $37,950 + $24,000 + $828 = $362,778
This example clearly shows how payroll costs extend far beyond base salaries.
Understanding Employer FICA (7.65%)
Employers must pay:
- 6.2% Social Security
- 1.45% Medicare
Total: 7.65%
This is separate from employee withholdings and is an additional employer expense.
Why Include Benefits in Payroll Cost?
Many business owners forget to include benefits when calculating labor costs.
Benefits can significantly increase your total payroll expenses, including:
- Health insurance premiums
- Retirement contributions
- Life insurance
- Disability coverage
Including them ensures accurate budgeting.
