Over 5+ yrs total $252,149

Fixed payment path generated through IRS mortality factor tables. Marginally lower or higher than amortization.

⚠️ IRA Split Tip: If the Amortization payment ($31,233/yr) is more than you actually need, split your IRA account balances first. To safely target an exact goal, partition a specific sub-portfolio size to lock in optimal payout values.
Calculations follow IRS Rev. Rul. 2002-62 rules. System maximum capped interest rate boundaries cannot exceed 120% of the active federal mid-term AFR indexes. Always consult a licensed tax professional or certified CPA advisor before triggering early SEPP distributions.

Frequently Asked Questions

Planning early retirement? Our 72(t) calculator shows your penalty-free IRA withdrawal options under Rule 72(t). Fast, accurate, built for FIRE planners.

Q1: What is a 72(t) SEPP distribution, and who qualifies?

A: A 72(t) SEPP (Substantially Equal Periodic Payment) is an IRS-approved method to withdraw from your IRA before age 59½ — without the standard 10% early withdrawal penalty. Any IRA owner under 59½ qualifies. Payments must follow one of three IRS-sanctioned calculation methods and continue for the SEPP required period (the longer of 5 years or until you reach age 59½).

Q2: How do you calculate 72(t) SEPP distributions?

A: The IRS allows three calculation methods: the RMD Method, Fixed Amortization, and Fixed Annuitization. Each uses your IRA account balance, current age, and an interest rate capped at 120% of the federal mid-term AFR. A 72(t) SEPP calculator runs all three simultaneously — so you can compare annual payout amounts before committing to one method.

Q3: How many years do 72(t) payments have to continue?

A: Payments must continue for the longer of two conditions: at least 5 full years, or until you reach age 59½. For example, if you start SEPP distributions at age 52, your required period is 8 years (until age 60). Starting earlier means a longer commitment — model this carefully before you begin.

Q4: Can you change the 72(t) SEPP payment amount once it has started?

A: Generally, no — and this is the biggest compliance risk. Once you lock in a SEPP schedule, changing the payment amount or stopping distributions early triggers a retroactive 10% penalty plus interest on all prior payments. The only permitted one-time change is switching from Fixed Amortization to the RMD Method — which some use strategically to reduce distributions during a market downturn.

Q5: Which 72(t) method pays out the most — Fixed Amortization or Annuitization?

A: Fixed Amortization typically yields the highest annual payout and is strongly interest-rate dependent. At a 5% rate on a $500,000 IRA, it can generate ~$30,773/year versus ~$14,665/year under Fixed Annuitization. The RMD Method pays the least but recalculates annually, giving you a built-in safety cushion if your balance drops.

Q6: What interest rate should I use for my 72(t) SEPP calculation?

A: The IRS caps the allowable rate at 120% of the federal mid-term Applicable Federal Rate (AFR) for the month of the first distribution. You can use any rate at or below that ceiling. Choosing a higher rate increases your payout — but also increases the risk of depleting your account. Always verify the current AFR on the IRS website before finalizing your election.

Q7: What is the IRA Split strategy for 72(t) SEPP, and when does it make sense?

A: If the maximum SEPP payout exceeds your actual income need, splitting your IRA into two accounts before starting distributions is a smart move. You apply Rule 72(t) only to the sub-account sized to generate your target income — leaving the remainder untouched to grow. This avoids over-withdrawing and preserves long-term tax-deferred growth on assets you don't need yet.

Q8: Does a 72(t) SEPP distribution avoid all taxes, or just the penalty?

A: It avoids only the 10% early withdrawal penalty — not income tax. All SEPP distributions from a traditional IRA are still taxed as ordinary income in the year received. If you hold a Roth IRA, different rules apply. Factor your effective tax rate into the net payout when comparing SEPP methods — gross withdrawal numbers alone can be misleading.
