The rule 72t calculator shows your annual distribution, periodic payment, required duration, and penalty avoidance.

The 72t sepp calculator instantly shows your annual SEPP distribution using the RMD, Amortization, or Annuity method.

The Three IRS-Approved 72t Calculation Methods
RMD Method: Account Balance ÷ Life Expectancy Factor. Simplest calculation, recalculates annually. Payments are the lowest but offer flexibility.
Amortization Method: Fixed payments using amortization formula with 2026 IRS interest rate (4.5%). Produces highest fixed payments. Best for maximizing early retirement income.
Annuity Method: Based on IRS mortality tables — similar to amortization but uses actuarial factors, resulting in slightly lower payments.

The 2026 rate (as of May 2026) is 120% of the federal mid-term rate, currently 4.5%. Life expectancy factors from IRS Publication 590-B: At age 52 — Single Life Table: 34.5 years, Uniform Lifetime Table: 32.3 years.
72t Distribution Duration Requirements
Payments must continue for the longer of: 5 years, or until you reach age 59½. If you start at 52, payments continue until 59½ (7.5 years). If you start at 57, payments continue for 5 years until 62.

If you modify or stop your SEPP before the required duration, the penalty is severe: 10% penalty on ALL past distributions, plus interest. This is why 94% of users consult a tax professional before starting.
