72(t) SEPP Calculator
Calculate substantially equal periodic payments from an IRA under section 72(t), comparing the required minimum distribution and fixed amortization methods, with the commitment each one locks you into.
How to use this calculator
- 1Enter the balance you intend to dedicate to the schedule, not necessarily your whole IRA.
- 2Enter your age when the first payment will be made.
- 3Choose the method — amortization for the largest payment, RMD for the smallest and most flexible.
- 4Leave the rate at 5% unless you have checked the federal mid-term AFR for one of the two months before payments start.
- 5Read the lock-in period carefully. It is the later of five years and age 59½, and breaking it is retroactive.
How the calculation works
RMD method: payment = balance ÷ life expectancy, recalculated annually. Fixed amortization: payment = balance × r ÷ (1 − (1 + r)^−n), where n is life expectancy and r the permitted rate- Life expectancy
- From the single life table in Treas. Reg. 1.401(a)(9)-9, updated in 2022
- r
- Any rate up to the greater of 5% or 120% of the federal mid-term AFR for one of the two months before the first payment
- Commitment
- The later of five years from the first payment and the date you reach 59½
The fixed annuitization method is the third permitted option and is not modelled here: it requires the annuity mortality table in Notice 2022-6 Appendix B, which is not carried in this codebase.
The account balance may be determined in any reasonable manner, which in practice means splitting an IRA first and running the schedule on a part large enough to produce the payment you want.
A one-time switch from either fixed method to the RMD method is permitted and is not a modification — the standard escape valve when a fixed payment is draining the account.
Worked example
$500,000 at age 50, fixed amortization at 5%
- 1.At 50 the single life table gives a life expectancy of 36.2 years.
- 2.Amortising $500,000 over 36.2 years at 5% gives a level payment of about $30,157 a year.
- 3.The RMD method would give only $500,000 ÷ 36.2, about $13,812 — less than half.
- 4.Starting at 50 means payments must continue until 59½, which is 9.5 years, not the five-year minimum.
- 5.Over 9.5 years that is roughly $286,000 of payments, all ordinary income.
Result: About $30,157 a year, locked in for 9.5 years
A commitment, not a withdrawal
Section 72(t)(2)(A)(iv) exempts a series of substantially equal periodic payments from the 10% early distribution tax. It is the main route to spending an IRA before 59½, and it is the one most early retirees have heard of.
What gets underweighted is that it is a binding commitment rather than a withdrawal strategy. Once payments start they must continue, in the same amount and on the same schedule, until the later of five years and the date you turn 59½. Stopping early, changing the amount, rolling the account over or taking an extra distribution from it all count as modifications.
The penalty for modifying is not prospective. Under section 72(t)(4) the 10% tax is applied retroactively to every payment already taken, plus interest for the deferral period. Someone who started at 50, took nine years of payments and then needed a lump sum in year nine faces a bill on the whole nine years.
The exceptions are narrow: death, disability, complete exhaustion of the account, and a one-time switch from either fixed method to the RMD method. That last one is the genuine escape valve, and it is worth knowing before you start rather than after.
Choosing the method, and the lever nobody mentions
Three methods are permitted. The RMD method divides the balance by life expectancy and is recalculated every year, so the payment moves with the account — smallest payment, most flexibility. The two fixed methods, amortization and annuitization, produce a level payment fixed at the outset, typically more than double the RMD figure.
The rate you may use for the fixed methods is capped at the greater of 5% or 120% of the federal mid-term applicable federal rate for one of the two months before the first payment. Notice 2022-6 introduced that 5% floor, and it was a significant liberalisation: in a low-rate environment the AFR-only cap had made fixed-method payments punishingly small.
The lever that matters most is not the method at all. The balance used may be determined in any reasonable manner, and there is no requirement to dedicate the whole account. The standard practice is to split an IRA into two before starting, run the schedule on the piece that produces exactly the payment you need, and leave the rest untouched and unencumbered. That preserves both flexibility and a source of emergency money that is not subject to the modification rules.
Why the rule of 55 usually beats it
For someone leaving a job at 55 or later, a 72(t) schedule is frequently the wrong instrument. The rule of 55 allows penalty-free withdrawals from the employer plan you just separated from, in any amount, on any schedule, with no commitment and no modification risk.
The catch is that it applies only to a workplace plan and only to the plan of the employer you separated from — not to an IRA, and not to a plan from an earlier job. This produces a common and expensive mistake: rolling a 401(k) into an IRA on leaving, which is the reflexive advice, permanently forfeits the rule of 55 for that money and leaves 72(t) as the only route.
The practical sequence for anyone separating at 55 or later is to leave the money in the plan until they are past 59½, use it as needed, and roll over afterwards. A 72(t) schedule then only makes sense for money already in an IRA, or for someone retiring well before 55.
What this assumes, and where it stops
Assumptions
- The single life table is used, which is the most common choice for a SEPP.
- The account balance entered is the amount dedicated to the schedule.
- Payments are annual; monthly or quarterly payments totalling the same annual amount are equally permitted.
- The interest rate entered is within the permitted ceiling for the month payments begin.
Limitations
- The fixed annuitization method is not modelled, because it needs the annuity mortality table in Notice 2022-6 Appendix B which is not carried here. It typically produces a payment close to fixed amortization.
- The joint and last survivor table, which is also permitted, is not carried.
- Under the RMD method the payment changes every year with the account balance; only the first year is shown.
- Interest on the retroactive penalty is not computed, so the figure for breaking the schedule is understated.
- State income tax and any state-level early distribution penalty are not included.
Common questions
How long do 72(t) payments have to continue?
Until the later of five years from the first payment and the date you reach age 59½. For someone starting at 50 that means nine and a half years, not five. For someone starting at 57 the five-year minimum runs past 59½, so five years is the answer. The distinction catches people out, because the rule is usually shortened to "five years" in general guidance.
What happens if I break a 72(t) schedule?
The 10% early distribution tax is applied retroactively to every payment you have already taken, not just to the one that broke the schedule, plus interest for the deferral period. On a decade of payments that is a substantial bill arriving at once. Death, disability, complete exhaustion of the account, and a single switch from a fixed method to the RMD method are the only ways out that do not count as modifications.
Which 72(t) method gives the highest payment?
Fixed amortization, usually by a factor of two or more over the RMD method, because it amortises the balance at an interest rate rather than simply dividing by life expectancy. Fixed annuitization gives a similar figure. The trade is rigidity: fixed payments stay the same even if the account falls sharply, which is how a SEPP can drain an account in a bad market. The RMD method moves with the balance.
Can I use 72(t) on my 401(k)?
Technically yes, but it is rarely the right move. If you separated from that employer at 55 or later, the rule of 55 lets you take whatever you want from that plan with no penalty and no commitment at all, which is strictly better. A 72(t) schedule makes sense for money already in an IRA, or for someone retiring well before 55. Rolling a 401(k) to an IRA on leaving destroys the rule of 55 option, so check before you move anything.
