72(t) SEPP Calculator – Penalty-Free Early IRA & 401(k) Withdrawals
Calculate your IRS Section 72(t) Substantially Equal Periodic Payments. See exactly how much you can withdraw penalty-free from your IRA or 401(k) before age 59½. Compare all three IRS-approved calculation methods.
⚠️ 72(t) plans must continue for 5 years or until age 59½ (whichever is longer). Breaking the plan early triggers retroactive 10% penalties on ALL prior withdrawals.

RMD Method: $12,195/year
Lowest. Recalculates each year based on account balance and IRS life expectancy table. Most flexible for changing account values.
Fixed Amortization: $26,931/year
Highest fixed payment. Uses the IRS mid-term AFR spread over your remaining life expectancy. Payment never changes.
Fixed Annuitization: $26,931/year
Very close to amortization in practice. Based on IRS mortality tables; this calculator approximates it with the amortization formula.
What Is a 72(t) SEPP?
Normally, withdrawing from an IRA or 401(k) before age 59½ costs a 10% early-withdrawal penalty on top of ordinary income tax. IRS Section 72(t)(2)(A)(iv) is the exception: it lets you take Substantially Equal Periodic Payments (SEPP) — fixed annual withdrawals calculated by one of three IRS-approved methods — with no 10% penalty, at any age.
A "SEPP IRA" is simply an IRA that carries a 72(t) plan. Because the payment schedule is locked for 5 years or until age 59½ (whichever is longer), most early retirees split their savings first and apply the rule to only part of their portfolio — see 72(t) SEPP Explained for the full walkthrough.
The Three IRS-Approved Calculation Methods
Rule 72(t) gives you exactly three ways to size the payments. Pick one at the start — switching later (other than a one-time move to the RMD method) retroactivates penalties.
1. RMD Method
Annual payment = account balance ÷ life-expectancy divisor (IRS Single Life Table). The payment recalculates every year, so it rises and falls with the account. It produces the lowest withdrawal and suits larger balances or conservative planners. Formula: Payment = Balance ÷ Divisor(Age).
2. Fixed Amortization
Spreads the balance over your life expectancy at a fixed interest rate. IRS guidance caps that rate at the greater of 5% or 120% of the federal mid-term rate (Notice 2022-6, which supersedes Rev. Rul. 2002-62 for payments starting on or after January 1, 2023; the 5% floor is new). The payment is a level annuity — the highest of the three methods. Formula: Payment = Balance × [r ÷ (1 − (1+r)−N)], where r is the chosen rate and N is your life expectancy in years.
3. Fixed Annuitization
Divides the balance by an annuity factor built from IRS mortality tables and the AFR. Payments land very close to the amortization method. This calculator approximates annuitization with the amortization formula, so the two figures match here — real annuitization payments differ slightly.
Year-by-Year SEPP Schedule
Worked example with the default inputs — age 45, $500,000 balance, 4.5% AFR: the RMD method pays about $12,195 per year, while fixed amortization pays $26,931 per year, level for every year of the plan. Because a SEPP must run for the later of five years from the first payment or age 59½ (IRC §72(t)(4)), a plan started at age 45 runs until you turn 59½ — a 14.5-year plan. Where that end date falls mid-year, the final row shows the prorated amount for the months actually paid.

72(t) Rules and Requirements
- Duration: payments must continue for the later of 5 years from the first payment or age 59½ (IRC §72(t)(4)).
- Locked method: you choose one calculation method up front. Only a one-time switch to the RMD method is allowed (IRS Revenue Ruling 2002-62).
- One plan per account: each IRA or 401(k) can carry only one 72(t) arrangement — another reason people split accounts first.
- Taxes still apply: 72(t) waives the 10% penalty only. Withdrawals are taxed as ordinary income.
- Account-based: the payment is fixed at the start and does not adjust for market losses — a steep downturn plus a high fixed payment can drain the account.
- Interest rate cap: the amortization and annuitization methods use a reasonable rate — no more than the greater of 5% or 120% of the federal mid-term rate for either of the two months before the first payment (Notice 2022-6, which supersedes Rev. Rul. 2002-62 for payments starting on or after January 1, 2023; the 5% floor is new). This calculator uses a 4.5% illustrative rate, which is within the cap.

72(t) SEPP Explained: How to Access Your IRA Before 59½ →Methodology & Data Sources
The life expectancy factors used in this calculator are taken from Table 1 (Single Life Table) of Treas. Reg. §1.401(a)(9)-9(b), finalized in T.D. 9930, 85 FR 72472 (November 12, 2020), which applies to distribution calendar years beginning on or after January 1, 2022. This is the same table the IRS publishes as Table I in Appendix B of IRS Publication 590-B.
SEPP plans started in 2021 or earlier may be subject to different table rules — consult a qualified tax professional about your specific plan.

72(t) Frequently Asked Questions
What is a 72(t) SEPP?
Section 72(t) allows you to take penalty-free withdrawals from your IRA or 401(k) before age 59½ through Substantially Equal Periodic Payments. You must continue payments for 5 years or until age 59½ — whichever is longer. Breaking the plan triggers retroactive 10% penalties on ALL prior withdrawals.
How can I withdraw from a 401(k) before 59½ without penalty?
Two common routes: (1) roll your 401(k) into an IRA and set up a 72(t) SEPP plan on that IRA, or (2) if you separate from service in or after the year you turn 55, use the Rule of 55 (IRC §72(t)(2)(A)(v)) to take penalty-free distributions from that employer's 401(k). Either way you still owe ordinary income tax on withdrawals.
Can I change or stop my SEPP payments after starting?
Generally no — the calculation method and amount are locked once the plan starts. The IRS allows one one-time switch to the RMD method (Revenue Ruling 2002-62). Any other modification or stop before the required period ends retroactivates the 10% penalty on every dollar withdrawn so far.
How long does a 72(t) plan have to continue?
Five years or until you turn 59½ — whichever is LATER (IRC §72(t)(4)). If you start at 52, the age rule binds and payments run until 59½ (7.5 years). If you start at 50, payments still run until 59½ (9.5 years), because that is longer than five years. If you start at 57 or later, the five-year rule binds instead — a plan started at 57 runs to age 62.
What is the 5-year rule for 72(t) plans?
The 5-year rule sets the minimum plan duration: payments must continue for the later of five years from the first payment or age 59½ (IRC §72(t)(4)). Start at 57 and the five-year rule binds — payments run to age 62. Start at 52 or younger and the age rule binds instead — payments run until 59½.
What happens if I terminate my SEPP early?
In the year you break the plan you owe the 10% additional tax on that year's total distributions, plus a recapture of the 10% tax for every prior year of the plan, plus interest (IRC §72(t)(1) and §72(t)(4)). On a plan paying $30,000 a year for four years, breaking it early can cost over $12,000 in recapture tax alone, before interest.
Which 72(t) method gives the highest withdrawal?
The Fixed Amortization method typically yields the highest annual withdrawal because it uses a fixed interest rate (the IRS AFR) spread over your life expectancy. The RMD method gives the lowest withdrawal but recalculates annually. Once you choose a method, you are locked in.
Can I split my IRA to use 72(t) on only part of it?
Yes — and this is a common strategy. You can transfer the amount you need into a separate IRA (a "SEPP IRA"), set up 72(t) on that account, and leave the rest untouched. This gives you flexibility if your needs change later.
What data source does this calculator use?
The life expectancy factors come from the Single Life Table in Treas. Reg. §1.401(a)(9)-9(b), finalized in T.D. 9930 (85 FR 72472) — the same table the IRS publishes as Table I in Publication 590-B, Appendix B. These tables apply to distribution calendar years beginning on or after January 1, 2022. SEPP plans started in 2021 or earlier should be reviewed with a qualified tax professional.
