Formula Used

The payroll calculation follows these steps:

Gross Pay Calculation

For hourly employees: Gross Pay = Hourly Wage × Hours Worked

For salaried employees: Gross Pay = Annual Salary ÷ Pay Periods per Year

Payroll Taxes

Federal Income Tax = Gross Pay × Federal Tax Rate

State Income Tax = Gross Pay × State Tax Rate

Social Security = Gross Pay × 6.2%

Medicare = Gross Pay × 1.45%

Net Pay Calculation

Net Pay = Gross Pay - (Federal Income Tax + State Income Tax + Social Security + Medicare)

Note: Tax rates are approximate and may vary based on individual circumstances. The calculator uses standard tax rates for the selected state.

Worked Example

Let's calculate payroll for an employee with the following details:

Hourly wage: $25/hour
Hours worked: 40 hours/week
Pay frequency: Weekly
State: California

Calculation Steps

Gross Pay = $25 × 40 = $1,000
Federal Income Tax = $1,000 × 12% = $120
State Income Tax (California) = $1,000 × 9.3% = $93
Social Security = $1,000 × 6.2% = $62
Medicare = $1,000 × 1.45% = $14.50
Net Pay = $1,000 - ($120 + $93 + $62 + $14.50) = $710.50

The calculator would show that for this employee, the net pay after taxes is $710.50 per week.

Interpreting Results

The payroll calculator provides several key metrics:

Gross Pay: The total amount earned before deductions
Net Pay: The amount the employee takes home after taxes and deductions
Payroll Taxes: The total taxes withheld from the employee's paycheck
