About the Payroll Tax Calculator
The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.
Formula basis:
SS Tax = min(wages, wage base - YTD) x 6.2% (employee and employer each)
Medicare = wages x 1.45% (both sides)
Additional Medicare = max(0, wages - $200,000) x 0.9% (employee only)
FUTA = min(wages, $7,000) x 0.6% (employer only)
Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.
Formula & How It Works
The calculation applies the following relations exactly as recorded in the metadata: SS Tax = min(wages, wage base - YTD) x 6.2% (employee and employer each) Medicare = wages x 1.45% (both sides) Additional Medicare = max(0, wages - $200,000) x 0.9% (employee only) FUTA = min(wages, $7,000) x 0.6% (employer only) Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.
Worked Examples
Example 1: Small business: paying one employee $52,000/year — employer taxes
Inputs
With Annual Gross Wages = 52,000, Filing Status = Single and YTD Wages Already Paid = 0 as the stated inputs, the result is Social Security = $3,224/yr, Medicare = $754/yr and Social Security = $3,224/yr. Each value corresponds to the declared output fields.
Example 2: Employee earning $85,000 single filer — net pay estimate
Inputs
With Annual Gross Wages = 85,000, Filing Status = Single and YTD Wages Already Paid = 0 as the stated inputs, the result is Social Security = $5,270/yr, Medicare = $1,232.5/yr and Social Security = $5,270/yr. Each value corresponds to the declared output fields.
Example 3: High earner: $250,000 single filer — SS wage base cap effect
Inputs
With Annual Gross Wages = 250,000, Filing Status = Single and YTD Wages Already Paid = 0 as the stated inputs, the result is Social Security = $10,453.2/yr, Medicare = $3,625/yr and Social Security = $10,453.2/yr. Each value corresponds to the declared output fields.
Example 4: Mid-year hire: employee joins July 1, will earn $90,000 by year-end; YTD from previous employer = $60,000
Inputs
With Annual Gross Wages = 90,000, Filing Status = Married Filing Jointly and YTD Wages Already Paid = 60,000 as the stated inputs, the result is Social Security = $5,580/yr, Medicare = $1,305/yr and Social Security = $5,580/yr. Each value corresponds to the declared output fields.
