Time Card Calculator with Social Security and Medicare Calculation

This time card calculator helps you determine your take-home pay after federal taxes including Social Security and Medicare deductions. Simply enter your gross pay and the calculator will show you how much you'll actually receive after taxes.

How This Calculator Works

When you receive a paycheck, your employer withholds federal taxes including Social Security and Medicare taxes. These taxes are calculated as percentages of your gross pay. The calculator uses these standard rates to show you what your net pay will be.

The current federal tax rates for Social Security and Medicare are:

Social Security: 6.2%
Medicare: 1.45%
Total federal taxes: 7.65%

The formula used is:

Net Pay = Gross Pay × (1 - (Social Security Rate + Medicare Rate))

For example, if your gross pay is $1,000, the calculation would be:

Net Pay = $1,000 × (1 - (0.062 + 0.0145)) = $1,000 × 0.9235 = $923.50

How to Use This Calculator

Enter your gross pay amount in the calculator form.
Click the "Calculate" button.

Example Calculation

Let's say you earn $1,500 per week. Here's how the calculation works:

Social Security Deduction = $1,500 × 6.2% = $93.00 Medicare Deduction = $1,500 × 1.45% = $21.75 Total Deductions = $93.00 + $21.75 = $114.75 Net Pay = $1,500 - $114.75 = $1,385.25

So with a $1,500 gross pay, your net pay after federal taxes would be $1,385.25.
