How much can I contribute?
- Elective Contributions
- Elective Deferral Limits
Each year the IRS determines the maximum amount you can contribute to tax-deferred savings plans like the TSP. This is known as the IRS elective deferral limit. Participants should use this calculator to determine the specific dollar amount to be deducted each pay period in order to maximize your contributions and to ensure that you do not miss out on Agency or Service Matching Contributions if you are entitled to them.
What information do you need to use this calculator?
- Your most recent Leave and Earnings statement or payslip.
- The number of salary payments you have left for the year.
Special Note for FERS and BRS Participants
This calculator is especially important for FERS employees and members of the
uniformed services covered by the Blended Retirement System (BRS). If you reach the
IRS elective deferral limit
before the end of the year, your contributions and Agency or Service Matching Contributions
must stop for the remainder of the year. As a result, you will lose some of your Agency or
Service Matching Contributions.
For more detailed information, read the Fact Sheet Annual Limit on Elective Deferrals.
The dollar amount determined by using this calculator distributes your employee/member contributions over the entire year (or remainder of the year), and thus allows you to receive the maximum Agency or Service Matching Contributions.
A summary of your computations based on the data you entered is shown below.
Maximizing Agency or Service Contributions
To receive the maximum Agency or Service Matching Contributions, you must contribute 5% of your basic pay each pay period.
Warning: Accuracy of Results
This calculator can provide you with a reasonable estimate. However, calculations may vary from actual contribution amounts because of a variety of factors influencing your pay (including pay increases) and the accuracy of the input.
Here’s the new amount you can contribute each remaining pay period if you want to maximize your contributions for YYYY (rounded down to the nearest dollar).
To change how much you contribute, log into your payroll system and select the Thrift Savings Plan option. Common payroll systems include
