Why This Calculator is Useful

Many employees only see the final “net pay” on their paycheck without fully understanding how deductions such as federal tax, state tax, and FICA (Social Security and Medicare) are applied. This calculator breaks down each deduction and shows you exactly where your money goes.

It’s especially useful if:

• You’re starting a new job and want to estimate your paycheck.
• You’re budgeting monthly expenses.
• You want to compare different work hours or rates.
• You’re an employer running quick payroll estimates.

• Tax rates change yearly; be sure to use current rates for accuracy.
• For salaried workers, this calculator works if you divide your annual salary into an hourly equivalent.
