Calculators
The MFPRSI calculators, Benefit Estimate and Tax Withholding, can help you estimate your future retirement benefits and the amount that should be withheld from your monthly benefit, respectively. Since these are planning tools, you can experiment by adding various data inputs, such as retirement dates and salary information on the Benefit Estimate calculator and number of allowances and additional amounts withheld on the Tax Withholding calculator.
These calculators are meant to provide guidance as to the totals of your monthly benefit and tax withholding and are not meant as guarantees of either your monthly benefit and tax withholding amounts.
