Produced by compute rmd.uniform-lifetime in src/lib/fiduciarybench/keys/index.ts — the stored value is machine-checked against the compute on every build; it cannot drift from its own code.
The RMD equals the prior-year-end balance divided by the Uniform Lifetime Table denominator for age 75, within $1.
“the benefit used in determining the required minimum distribution for a distribution calendar year is the account balance as of the last valuation date in the calendar year preceding that distribution calendar year”
“is determined using the Uniform Lifetime Table in § 1.401(a)(9)-9(c) for the employee's age as of the employee's birthday in the relevant distribution calendar year”
“the Uniform Lifetime Table, sets forth the applicable denominator that applies for lifetime distributions to an employee in situations in which the employee's surviving spouse is not the sole designated beneficiary”

“is equal to the quotient obtained by dividing the account balance (determined under paragraph (b) of this section) by the applicable denominator” — cfr-1-401a9-5
Under § 1.401(a)(9)-5(a)(1), the required minimum distribution is calculated by dividing the account balance by the applicable denominator. The account balance is $1,240,000. Because the surviving spouse is not the sole designated beneficiary, the applicable denominator is determined using the Uniform Lifetime Table in § 1.401(a)(9)-9(c). For an employee who is age 75, the applicable denominator is 24.6. Dividing $1,240,000 by 24.6 yields approximately $50,406.50, which matches the key.
“72 | 27.4 73 | 26.5 74 | 25.5 75 | 24.6” — cfr-1-401a9-9
The employee is age 75 and the surviving spouse is not the sole designated beneficiary, so the Uniform Lifetime Table applies. The table gives an applicable denominator of 24.6 for age 75. Dividing the prior year-end account balance of $1,240,000 by 24.6 yields $50,406.504..., which rounds to $50,406.50, matching the key value within the ±1 tolerance.
