RMD Calculator

The RMD Calculator computes the Required Minimum Distribution you must withdraw each year from tax-deferred retirement accounts such as Traditional IRAs and 401(k)s once you reach the mandatory age. The IRS requires these withdrawals so that tax-deferred savings are eventually taxed; failing to take them triggers a steep excise penalty, making accurate calculation important for retirees.

The calculation divides your prior-year-end account balance by a life-expectancy factor from the IRS Uniform Lifetime Table (or the Joint Life Table if your sole beneficiary is a spouse more than ten years younger). As you age, the divisor shrinks, so the required percentage of your balance rises each year. The tool automates this lookup and division so you don't have to interpret the IRS tables manually.

Use it to plan the tax impact of distributions, since RMDs count as ordinary income and can push you into a higher bracket or affect Medicare premiums and Social Security taxation. The required beginning age has moved over time under the SECURE Act legislation, currently age 73 for many savers, so confirm the age that applies to your birth year. Roth IRAs are not subject to RMDs during the original owner's lifetime, a key planning distinction.

Practical tips: aggregate IRA RMDs can be taken from any one IRA, but 401(k) RMDs must generally be taken from each plan separately. Consider Qualified Charitable Distributions to satisfy your RMD tax-efficiently if you give to charity, and coordinate with an IRA Calculator and 401(k) Calculator while still saving so you understand the future distribution obligations you are building.
