403b Minimum Distribution Calculator
🚀 What is a 403(b) RMD?
A 403(b) Required Minimum Distribution is the minimum amount you must withdraw annually from your 403(b) retirement account once you reach age 73 (starting from 2023, previously age 72). These distributions are mandated by the Internal Revenue Service (IRS) to ensure that retirement savings are eventually taxed.
🧠 Why Use a 403(b) RMD Calculator?
The RMD formula can be confusing due to varying divisors, beneficiary rules, and account balances. Our calculator:

$250,000 - Enter
75 - Select
Spouse is sole beneficiary... - Enter
62 - Click “Calculate”
Result:
- RMD: ~$10,162.60 (depending on divisor logic)

📈 How the Calculator Works
The calculator uses two main IRS tables:
- Uniform Lifetime Table: Used for most individuals.
- Joint Life Table: Used when your spouse is more than 10 years younger and is your sole beneficiary.
The divisor from the appropriate table is used to divide your 403(b) balance, giving you the minimum withdrawal amount required.
🧮 Formula:
RMD = Account Balance / IRS Divisor
The divisor varies by age. For example:
- Age 73: Divisor = 26.5
- Age 75: Divisor = 24.6
- Age 90: Divisor = 12.2
The calculator includes logic to auto-adjust the divisor if the spousal condition is met, using a simplified joint expectancy table.
