The 72tNET website offers three calculators to help you develop your 72t SEPP plan.
The SEPP Distribution calculator helps you determine the amount you can withdraw annually from your retirement account(s).
The Minimum Balance calculator is exclusive to 72tNET and helps you calculate the initial balance you should have in your SEPP retirement account(s) so you can withdraw the exact annual distribution amount you need.
Also exclusive to 72tNET, the First Modification Date calculator determines the date at which you will have fulfilled your SEPP obligation and can modify your distribution payment amounts. After this date you are free to take any distribution amount you want.
