About this tool

Enter your yearly wages. The calculator applies Social Security at 6.2 percent up to the wage base and Medicare at 1.45 percent, plus the additional 0.9 percent Medicare tax over $200,000, and shows the matching employer share. Figures are for the 2026 tax year and can change. A guide only, check irs.gov or a tax professional.

What FICA is

FICA stands for the Federal Insurance Contributions Act. Social Security funds retirement and disability benefits, and Medicare funds health insurance for older adults. Employees and employers each pay 7.65 percent of wages up to the Social Security wage base of $184,500 in 2026.

Example

On $75,000 of wages, Social Security is $4,650 and Medicare is $1,088, a total of $5,738 or 7.65 percent. The employer pays the same amount again.

Not included

This is separate from federal and state income tax. The self-employed pay both halves, see the self-employment tax calculator.
