Comprehensive Guide: How to Calculate RMDs (Required Minimum Distributions)

Required Minimum Distributions (RMDs) are mandatory withdrawals from retirement accounts that must begin when you reach a certain age. The SECURE Act 2.0 changed the RMD age to 73 for those who turn 72 after December 31, 2022, and will increase to 75 in 2033. Failing to take RMDs results in a 25% penalty (reduced from 50% in 2023) on the amount not withdrawn.

Who Must Take RMDs?

RMD rules apply to:

  • Traditional IRAs
  • SEP IRAs
  • SIMPLE IRAs
  • 401(k), 403(b), and 457(b) plans
  • Profit-sharing plans
  • Other defined contribution plans

Roth IRAs do not require withdrawals until after the death of the owner.

When Must You Take Your First RMD?

Your first RMD is due by:

  • April 1 of the year after you turn the RMD age (73 for most people)
  • December 31 of the same year for all subsequent RMDs
RMD Age Requirements by Birth Year
Birth Year RMD Age First RMD Deadline
Before 1951 70½ April 1 after turning 70½
1951-1959 72 April 1 after turning 72
1960 or later 73 April 1 after turning 73

How to Calculate Your RMD

The RMD calculation involves three key steps:

  1. Determine your account balance as of December 31 of the previous year
  2. Find your life expectancy factor from the IRS tables (Uniform Lifetime, Joint Life, or Single Life)
  3. Divide your account balance by the life expectancy factor

Formula: RMD = Account Balance ÷ Life Expectancy Factor

IRS Life Expectancy Tables

The IRS provides three tables for calculating RMDs:

  1. Uniform Lifetime Table – Used by most retirees (unmarried owners, married owners whose spouses aren’t more than 10 years younger, and married owners whose spouses aren’t the sole beneficiaries)
  2. Joint Life and Last Survivor Table – Used when the sole beneficiary is a spouse who is more than 10 years younger
  3. Single Life Expectancy Table – Used by beneficiaries of inherited IRAs
Sample Uniform Lifetime Table Factors (2024)
Age Life Expectancy Factor Age Life Expectancy Factor
70 27.4 85 14.8
72 25.6 90 11.4
75 22.9 95 8.6
80 18.7 100 6.3

Common RMD Mistakes to Avoid

  • Missing the deadline – First RMD has a special April 1 deadline, but subsequent RMDs are due by December 31
  • Calculating incorrectly – Using the wrong life expectancy table or account balance
  • Not taking RMDs from all accounts – You must calculate RMDs separately for each IRA, though you can withdraw the total from one account
  • Forgetting about inherited IRAs – Beneficiaries have different RMD rules
  • Ignoring Roth 401(k) RMDs – Unlike Roth IRAs, Roth 401(k)s require RMDs

Strategies to Manage RMDs

While you can’t avoid RMDs, you can implement strategies to minimize their impact:

  1. Qualified Charitable Distributions (QCDs) – Directly transfer up to $100,000/year to charity tax-free (counts toward RMD)
  2. Roth conversions – Convert traditional IRA funds to Roth IRAs before RMDs begin (no RMDs for Roth IRAs)
  3. Withdraw more than the RMD – Take larger distributions in low-income years to reduce future RMDs
  4. Use RMDs for reinvestment – Reinvest RMD amounts in taxable accounts for continued growth
  5. Consider annuities – Qualified Longevity Annuity Contracts (QLACs) can reduce RMD amounts

RMD Rules for Inherited IRAs

The SECURE Act changed inheritance rules significantly:

  • Spouse beneficiaries can treat the IRA as their own or roll it over
  • Non-spouse beneficiaries (most cases) must empty the account within 10 years (no annual RMDs, but full distribution by year 10)
  • Eligible designated beneficiaries (minor children, disabled/chronically ill individuals, or beneficiaries not more than 10 years younger) can stretch distributions over their life expectancy

Tax Implications of RMDs

RMDs are treated as ordinary income and subject to federal income tax (and possibly state tax). Key considerations:

  • Withholdings – You can elect to have federal/state taxes withheld from RMDs
  • Estimated taxes – Large RMDs may require quarterly estimated tax payments
  • Tax brackets – RMDs may push you into a higher tax bracket
  • IRMAA – Higher income from RMDs may increase Medicare premiums
  • State taxes – Some states don’t tax retirement income

Frequently Asked Questions About RMDs

Can I take my RMD in monthly payments?

Yes, you can take your RMD in installments throughout the year as long as the total amount meets or exceeds your calculated RMD by December 31.

What if I have multiple retirement accounts?

For IRAs (including SEP and SIMPLE IRAs), you must calculate the RMD for each account but can withdraw the total from one or more accounts. For 401(k)s and similar plans, you must take RMDs separately from each account.

Can I reinvest my RMD?

Yes, you can reinvest your RMD proceeds in a taxable brokerage account. However, you cannot roll over RMD amounts into another retirement account.

What happens if I don’t take my RMD?

The penalty for missing an RMD is 25% of the amount not taken (reduced from 50% in 2023). For example, if your RMD was $10,000 and you didn’t take it, you’d owe $2,500 in penalties.

Do RMDs affect Social Security benefits?

RMDs count as income, which may make more of your Social Security benefits taxable (up to 85% of benefits can be taxable depending on your income level).
