Identify the account type: traditional IRA, SEP IRA, SIMPLE IRA, 401(k), 403(b), or other eligible retirement account
Find your prior year-end account balance
Determine your RMD age and required starting date
Use the IRS Uniform Lifetime Table unless a different table applies
Divide the prior year-end balance by the distribution period from the table
If you have multiple IRAs, calculate each IRA’s RMD separately, then total them
If you have multiple 401(k)-type accounts, calculate and take the RMD from each account separately
Subtract any RMDs already taken for the year
Use the result as the remaining amount you must withdraw
