What Is 72(t) SEPP Early Withdrawal?
IRS Rule 72(t) allows you to take Substantially Equal Periodic Payments (SEPP) from an IRA or 401(k) before age 59½ without paying the normal 10% early withdrawal penalty. It was designed to give people who retire early legitimate access to their retirement accounts without the penalty that otherwise applies to early distributions.
The catch is the commitment: once you start a SEPP plan, you must continue taking exactly the same distributions (or the IRS-recalculated equivalent under the RMD method) for the longer of five years or until you reach age 59½. Any modification, including stopping the payments, changing the amount, or rolling the account over, terminates the plan and triggers retroactive 10% penalties plus interest on all prior distributions. It is one of the most inflexible strategies in the retirement planning toolkit, which is exactly what makes the readiness question so important.
How This Calculator Works
The IRS allows three methods for calculating your SEPP amount. All three use your account balance and your IRS life expectancy factor (from the Single Life Expectancy Table in Pub 590-B). The methods differ in how they treat the Applicable Federal Rate (AFR) and whether the payment is fixed or recalculated annually.
Personal Considerations
The psychological challenge with 72(t) isn't understanding the math, it's accepting the inflexibility. People who are otherwise financially sophisticated sometimes underestimate how much their life can change over a 5-10 year commitment period. A medical event, a major expense, a change in living situation, or a business opportunity that requires capital can all create pressure to modify the plan, which is exactly what you can't do. Running the 72(t) Readiness Assessment alongside this calculator is worth doing before committing.
There's also an anchoring risk on the payment amount. The amortization and annuitization methods produce relatively high fixed payments, which can be appealing when you're cash-constrained in early retirement. But the plan is built around that amount permanently, and locking in a high withdrawal rate in the early years of retirement can create real problems if returns disappoint or expenses change.

Frequently Asked Questions
Yes. You can split your IRA into two accounts and apply 72(t) only to one of them, leaving the other untouched until 59½. This is a common strategy for people who need only part of their account balance to cover early retirement expenses.
The Applicable Federal Rate is published monthly by the IRS in a Revenue Ruling (typically titled Rev. Rul. [year]-[number]). For 72(t), you use the mid-term AFR, and you're allowed to use the rate from either of the two months before your first distribution. The IRS also allows up to 120% of that rate.
You cannot, without triggering retroactive penalties. If circumstances genuinely change and you cannot maintain the plan, the only IRS-recognized relief is a method switch from Amortization or Annuitization to the RMD method, which is allowed once and can reduce future payments to the lower, recalculated amount.
No. Other options include: Roth conversion ladders (tax-free after 5-year seasoning), 72(t) applied only to a separated 401(k) after leaving a job, substantially equal withdrawals from a Roth IRA contribution basis (not earnings), HSA distributions for qualified medical expenses, and a few IRS hardship exceptions. 72(t) is most useful when you have a large Traditional IRA and no other low-penalty access path.
