This calculator uses information you enter from your pay stub to help you determine the highest TDA contribution rate that may be implemented on payroll.
TDA contributions can be deducted from your pay only after certain other deductions are taken. Use this tool to find out how much of your pay remains after those deductions—and the TDA contribution rate that this equates to.
The calculated contribution is likely to be implemented successfully on payroll, based on the information you entered. However, if the rate is too high (the requested TDA deduction exceeds the amount available to deduct), then no TDA deduction would be taken from your pay. Please use caution when electing a high TDA contribution rate.
Please refer to your most recent pay stub (or online pay statement) to enter the following information.
