How to Use This 72(t) SEPP Calculator
Enter your retirement account balance, current age, and the interest rate you will use (up to 120% of AFR). The calculator computes your required annual payment under all three IRS-approved methods. The commitment period is the longer of 5 years or until age 59½.
Formulas
Commitment Period = max(5 years, 59.5 − current age)
RMD Method: Payment = Balance ÷ Life Expectancy Factor (IRS Uniform Table)
Amortization: Payment = Balance × [r / (1 − (1+r)^−n)] where r = AFR, n = life expectancy
Annuitization: Payment = Balance ÷ Annuity Factor (IRS table at AFR)
RMD Method: Payment = Balance ÷ Life Expectancy Factor (IRS Uniform Table)
Amortization: Payment = Balance × [r / (1 − (1+r)^−n)] where r = AFR, n = life expectancy
Annuitization: Payment = Balance ÷ Annuity Factor (IRS table at AFR)

Example
Age 45 with $500,000 IRA, 4.5% AFR rate:
Commitment period: max(5, 59.5−45) = 14.5 years
Life expectancy factor: 38.8 years
RMD method: $500,000 ÷ 38.8 = $12,887/year
Amortization: $500,000 × [4.5%/(1−(1.045)^−38.8)] = ~$27,300/year
Amortization typically gives 2–3× more annual income than RMD method

Frequently Asked Questions
What is Rule 72(t) and how does SEPP work?
Rule 72(t) of the Internal Revenue Code allows penalty-free early withdrawals from IRAs, 401(k)s, and similar retirement accounts before age 59½ through Substantially Equal Periodic Payments (SEPP). You must commit to receiving payments for the longer of: 5 years or until you turn 59½. Once begun, the payment amount cannot be modified (except for a one-time switch from amortization to RMD method). Violating the schedule triggers a retroactive 10% penalty on all prior payments, plus interest.
What are the three SEPP calculation methods?
The three IRS-approved SEPP methods are: (1) Required Minimum Distribution (RMD) method — payment is recalculated annually by dividing account balance by life expectancy factor; amounts vary each year. (2) Amortization method — payment is fixed using account balance, life expectancy, and the federal mid-term AFR; typically produces the highest annual payment. (3) Annuitization method — payment is fixed using an annuity factor; similar to amortization. IRS Notice 2022-6 governs current SEPP rules.
What interest rate should I use for SEPP calculations?
For the amortization and annuitization methods, you may use any interest rate up to 120% of the federal mid-term Applicable Federal Rate (AFR) for either of the two months preceding the first SEPP payment. The April 2026 federal mid-term AFR is approximately 4.50%, so you could use up to 5.40% (120%). Using a higher rate produces a larger annual payment, which may be advantageous if you need more income. The RMD method does not use an interest rate.
What happens if I modify or stop my SEPP payments?
If you modify the SEPP schedule before the later of 5 years or age 59½, the IRS will impose a 10% early withdrawal penalty retroactively on ALL previous SEPP distributions, plus interest. The only permitted change is a one-time switch from the amortization or annuitization method to the RMD method. Common modifications that trigger penalties include: changing the payment amount, taking an extra distribution, rolling over part of the account, or stopping payments early.
Is SEPP taxable income?
Yes. SEPP payments avoid the 10% early withdrawal penalty, but they are still fully taxable as ordinary income (for traditional IRA/401k). The payments are not tax-free — they simply bypass the 10% penalty. You will receive a 1099-R showing the distribution, and you report it on Form 5329 to claim the penalty exception (Code 02). Plan to set aside roughly 25%–35% for federal and state income taxes depending on your bracket.
