Calculate required minimum withdrawals for eligible retirement accounts.
Overview
Required Minimum Distributions (RMDs) are mandatory withdrawals for certain retirement accounts once you reach applicable distribution age. Missing RMDs can trigger significant penalties.
This calculator estimates annual RMD amount using prior year-end account balance and life expectancy divisor assumptions. It helps with tax and cash-flow planning.
RMD rules can change and may vary by account type and beneficiary status, so always confirm with current IRS guidance and your custodian.
Steps
Use official December 31 statement value.
Match your age for the current RMD year.
Use relevant IRS table divisor for your case.
Divide account balance by divisor.
Estimate tax impact of required withdrawal.
Repeat for each account where aggregation rules require.
Math
RMD = Prior year-end account balance / IRS life expectancy divisor
RMD amounts are based on account value at prior year-end and the divisor from the applicable IRS life expectancy table for your age and status.
