For 2025, Social Security tax is calculated as your gross earnings times 6.2%. For 2025, incomes over $176,100 that have already had the maximum Social Security tax of $10,918.20 withheld will not have additional withholding. Please note that if you have other wages or employers this calculator does not make any assumptions as to the total Social Security tax withheld for the current year other than the actual inputs for this calculator. This tax is also referred to as the Federal Insurance Contributions Act Old Age Survivors and Disability Insurance (FICA OASDI).
Medicare tax is calculated as your gross earnings times 1.45%. Unlike the Social Security tax, there is no annual limit to the Medicare tax. Starting in 2013, an additional Medicare tax of 0.9% is withheld on all gross earnings paid in excess of $200,000 in a calendar year. If you enter an amount for the year-to-date gross earnings, this additional Medicare tax will be calculated based on the current period's gross earnings that exceed the annual $200,000 threshold. If no year-to-date amount is entered, any additional Medicare tax withholding will be calculated only for any gross earnings in excess of $200,000 for the current payroll period. If year-to-date wages prior to the current payroll period have exceeded $200,000, the year-to-date wages must be entered to calculate an accurate additional Medicare tax.

Choose the type of 457 plan contributions. The choices are pre-tax and after-tax.
The current balance of your retirement plan.
Your current age.
Age you wish to retire. This calculator assumes that the year you retire, you do not make any contributions. For example, if you retire at age 65, your last contribution occurs when you are actually 64.
Your total contribution for one year is based on your annual salary times the percent you contribute. However, your annual contribution is also subject to certain maximum total contributions per year. For 2025, the maximum contribution for this type of plan is $23,500 per year for individuals under age 50. For individuals age 60 to 63 the limit is $34,750. For all other individuals age 50 or older the limit is $31,000. It is also important to note that employer contributions do not affect an employee's maximum annual contribution limit. The catch-up amount is indexed for inflation in increments of $500.
It is important to note that some employees are subject to another form of contribution limitations. Employees classified as 'Highly Compensated' may be subject to contribution limits based on their employer's overall participation. If you expect your salary to be $160,000 or more in 2025 or was $155,000 or more in 2024, you may need to contact your employer to see if these additional contribution limits apply to you.
