Retirement
72(t) SEPP Calculator
Rule 72(t) lets you tap a retirement account before 59½ without the 10% penalty, provided you take substantially equal periodic payments. Two methods set the amount: the RMD method, which varies yearly, and fixed amortization, which is level and usually larger.
Tested against worked examplesHow we verify
From the IRS Single Life Table for your age — about 36.2 at age 50.
Capped at 120% of the federal mid-term rate for the amortization method.
Annual withdrawal (amortization method): $30,217
Annual withdrawal (amortization method)
$30,217
About $2,518 a month, level for the whole schedule.
A 72(t) schedule is a serious commitment: once started, you must continue substantially equal payments for five years or until 59½, whichever is longer. Change the amount, add to the account, or stop early, and the IRS retroactively applies the 10% penalty plus interest to every withdrawal. Set this up with a tax professional.

How this calculator works
The RMD method divides the balance by the life-expectancy divisor you supply from the IRS Single Life Table. Fixed amortization computes a level annual payment that amortises the balance over that life expectancy at the interest rate — capped in practice at 120% of the federal mid-term rate. The penalty avoided is 10% of the first year's withdrawal.
Fixed annuitization, the third IRS method, uses an actuarial mortality factor and lands very close to amortization, so it is not shown separately. The divisor and rate are inputs — confirm the correct life-expectancy factor and the current maximum rate before filing. Given the retroactive penalty for errors, this is a decision for a tax professional.
What this assumes
- Substantially equal periodic payments must continue for five years or until 59½, whichever is longer. Modifying or stopping early retroactively applies the 10% penalty to every distribution taken.
- One of the three IRS-approved calculation methods, using the interest rate and life expectancy table entered.
- This is a rigid commitment with unforgiving rules. It is a case for professional advice rather than a calculator alone.
What changes this number
- The lock-in period
- The defining risk. Circumstances change over five years, and the schedule does not.
- Which method you choose
- The three methods produce materially different payments from the same balance.
- Account balance used
- Splitting an IRA before starting lets you size the payment, since the schedule is calculated on the account you designate.

Frequently asked questions
What is a 72(t) SEPP?
A series of substantially equal periodic payments from an IRA or, after leaving a job, a 401(k), taken under IRS Rule 72(t). It lets you access retirement money before 59½ without the usual 10% early-withdrawal penalty — the main legal route to funding an early retirement from tax-advantaged accounts.
How long must the payments continue?
For five years or until you reach 59½, whichever is longer. Start at 50 and you are committed until 59½ — nearly a decade. Start at 58 and you must continue until 63, past 59½, because the five-year minimum still applies. There is no early exit without penalty.
What are the calculation methods?
Three are allowed: the required minimum distribution method (balance divided by a life-expectancy factor, recomputed yearly, so it varies), fixed amortization (a level payment over life expectancy at an approved rate), and fixed annuitization (using an actuarial factor, landing close to amortization). Amortization usually produces the largest, steadiest payment.
What happens if I break the schedule?
The penalty is severe and retroactive. Modify the payments, take an extra distribution, or contribute to the account before the schedule ends, and the IRS applies the 10% penalty to every SEPP withdrawal you have taken, plus interest. One allowed switch to the RMD method exists, but otherwise the schedule is rigid.
Should I use a 72(t)?
Only when you genuinely need pre-59½ access and have no better source, because the commitment is long and unforgiving. Many early retirees instead bridge with taxable accounts and Roth contributions, which are more flexible, and reserve 72(t) for when those run short. It is powerful but rigid — plan it with an advisor.
