RMD Age Calculator: Find Your Required Minimum Distribution Start Date
Use this guide to understand the assumptions, inputs, results, and next steps behind the calculator.
Quick Summary
Determine the exact age and year you must begin taking Required Minimum Distributions (RMDs) from your retirement accounts. This calculator uses the latest SECURE Act 2.0 rules based on your birth year to identify your specific RMD start date, helping you avoid costly penalties and plan your withdrawal strategy.
This tool is for anyone approaching retirement or managing a pre-tax retirement account like a Traditional IRA or 401(k). If you need to calculate the specific dollar amount of your withdrawal, use the main RMD Calculator. To project future RMDs, try the Future RMD Calculator. For a complete overview of the rules, see our guide on Required Minimum Distributions explained.
The calculator provides your RMD start age, the calendar year your RMDs begin, and the deadline for your very first withdrawal. By entering your account balance, you can also get an estimate of your first RMD amount. The results include a clear reference table showing how the RMD age has changed, so you can see exactly which rule applies to you.
How To Use This Calculator
Start by entering your birth year. This is the most important factor, as the SECURE Act 2.0 sets different RMD starting ages for different birth cohorts.
Next, select your account type. The rules can differ for a Traditional IRA, a 401(k), or an Inherited IRA. This choice helps the calculator apply any special exceptions that may be relevant to your situation.
Then, indicate if you are still working. This input is used to determine if you qualify for the "still-working exception," which allows some individuals to delay RMDs from their current employer's 401(k) plan.
For a more detailed projection, open the advanced settings. Here you can enter your current account balance and an expected annual return. These optional inputs allow the calculator to project your account's growth and estimate the dollar amount of your first RMD, giving you a more complete picture of what to expect.
What Each Input Means
Birth Year
Your birth year is the primary factor that determines your RMD starting age. The SECURE Act of 2019 and the SECURE 2.0 Act of 2022 created three different age tiers. This calculator automatically applies the correct age (72, 73, or 75) based on the year you were born.
Account Type
The type of retirement account you have can affect your RMD rules.
- Traditional IRA: RMDs must begin at your designated start age, regardless of your employment status. This also applies to SEP IRAs and SIMPLE IRAs.
- 401(k): These accounts follow the standard RMD age rules. However, if you are still working for the company that sponsors the 401(k), you may be able to delay RMDs from that specific plan. This is known as the still-working exception. This also applies to 403(b) and other defined contribution plans.
- Inherited IRA: The rules for inherited accounts are complex and depend on your relationship to the original owner and when they passed away. Most non-spouse beneficiaries are now subject to a 10-year withdrawal rule. Use the non-spouse inherited IRA RMD calculator for specific guidance.
Still Working
This input determines if you qualify for the still-working exception. If you are still employed past your RMD start age and are not a 5% owner of the company, you can generally delay RMDs from your current employer's 401(k) or 403(b) plan until you retire. This exception does not apply to IRAs or 401(k)s from previous employers.
Current Account Balance & Expected Return
These optional inputs are used to estimate the size of your first RMD. The calculator projects your balance forward from today until your RMD start year using the expected annual return you provide. This helps you anticipate the potential tax impact of your first required withdrawal. For more detailed tax planning, use the RMD Tax Calculator.
How The Calculator Works
This calculator determines your RMD timeline using a clear, rule-based process.
First, it identifies your RMD start age by comparing your birth year to the thresholds established by the SECURE Act 2.0.
Next, it checks for exceptions. If you select "401(k)" as the account type and indicate you are "still working," the calculator applies the still-working exception and adjusts your RMD start age to your retirement year (if later than the standard age). For Inherited IRAs, it notes that different rules apply, often requiring faster distributions.
The calculator then calculates your RMD start year by adding your RMD start age to your birth year. The deadline for your first RMD is set to April 1 of the year following your start year, per IRS rules.
If you provide a balance and return rate, the calculator runs a simple projection. It compounds your current balance annually by the expected return for the number of years remaining until your RMDs begin. It then estimates your first RMD by dividing that projected balance by the appropriate life expectancy factor from the IRS Uniform Lifetime Table.
Calculator Formula
The calculator uses a series of logical steps and formulas to determine your RMD age and estimated first withdrawal.
RMD Start Age Determination
The calculator uses the following logic based on SECURE Act 2.0 rules:
IF birth year <= 1950, THEN RMD start age = 72
ELSE IF birth year >= 1951 AND birth year <= 1959, THEN RMD start age = 73
ELSE IF birth year >= 1960, THEN RMD start age = 75
Effective RMD Age (with Still-Working Exception)
If the still-working exception applies, the start age is delayed.
IF still working exception applies, THEN effective RMD age = retirement age (assumed to be at least current age + 1)
ELSE effective RMD age = RMD start age
RMD Timeline Calculation
RMD start year = birth year + effective RMD age
First RMD deadline = April 1 of (RMD start year + 1)
Years until RMD = RMD start year - current year
Estimated First RMD Calculation
This calculation is performed if a balance is entered.
Projected balance = current balance * (1 + expected annual return) ^ years until RMD
Estimated first RMD = projected balance / IRS life expectancy factor for RMD start age
When Do RMDs Start? The SECURE Act 2.0 Rules
Required Minimum Distributions are the minimum amounts you must withdraw from most retirement accounts annually, starting at a certain age. The age you must begin taking RMDs was changed by the SECURE Act of 2019 and the SECURE 2.0 Act of 2022. The specific age depends on when you were born.
Here is a breakdown of the RMD starting ages:
| If you were born... | Your RMD Start Age is... | Governed By |
|---|---|---|
| 1950 or earlier | 72 | Original SECURE Act |
| Between 1951 and 1959 | 73 | SECURE Act 2.0 |
| 1960 or later | 75 | SECURE Act 2.0 |
These rules apply to traditional retirement plans like 401(k)s, 403(b)s, Traditional IRAs, SEP IRAs, and SIMPLE IRAs. As of 2024, neither Roth 401(k)s nor Roth IRAs are subject to RMDs for the original owner under SECURE 2.0. Understanding your correct start age is the first step in creating a compliant withdrawal plan and developing RMD strategies to minimize the tax hit.
The Still-Working Exception Explained
A common RMD planning question is whether you can delay withdrawals if you continue working past the standard RMD age. The answer is yes, but only for certain accounts.
The "still-working exception" allows you to delay RMDs from your current employer's 401(k) or 403(b) plan until you actually retire.
To qualify, you must:
- Be employed past your RMD start age (73 or 75).
- The retirement plan must be with your current employer.
- You cannot be a 5% or greater owner of the company.
This exception does not apply to:
- Traditional IRAs, SEP IRAs, or SIMPLE IRAs.
- 401(k) or 403(b) plans from previous employers.
For example, if you are 74, still working, and have a 401(k) with your current job and a Traditional IRA, you must take an RMD from the IRA. However, you can delay taking an RMD from the 401(k) until you retire. This can be a powerful tool for allowing more of your savings to grow tax-deferred.
RMD Rules for Inherited IRAs
When you inherit a retirement account, the RMD rules are different and often more aggressive. The SECURE Act significantly changed these rules for most non-spouse beneficiaries.
- Spouse Beneficiaries: A surviving spouse has the most flexibility. They can treat the inherited IRA as their own, rolling it over into their personal IRA. This allows them to delay RMDs until they reach their own RMD start age.
- Non-Spouse Beneficiaries (Post-2019 Deaths): For most non-spouse beneficiaries who inherit an IRA from someone who passed away in 2020 or later, the account must be fully distributed within 10 years of the original owner's death. Annual RMDs may also be required during this 10-year period if the original owner had already started taking their own RMDs.
- Exceptions: There are exceptions to the 10-year rule for certain "eligible designated beneficiaries," including minor children, disabled or chronically ill individuals, and beneficiaries not more than 10 years younger than the decedent.
Inherited IRA rules are complex. If you have inherited an account, it is crucial to understand your specific obligations. Use the inherited IRA calculator for more personalized information.
Understanding Your Results
- RMD Start Age: This is the age you must take your first RMD, based on your birth year and any applicable exceptions.
- RMD Start Year: This is the first calendar year for which an RMD is required. Your RMD is calculated based on your account balance on December 31 of the prior year.
- First RMD Deadline: You have until April 1 of the year following your RMD start year to take your very first RMD. However, if you delay, you will have to take two RMDs in that second year (the one for the first year and the one for the current year), which could result in a higher tax bill.
- Estimated First RMD: If you provided an account balance, this is a projection of the amount you'll need to withdraw. This helps you plan for the income and potential tax impact. You can use this figure in our RMD Tax Withholding Calculator to estimate your tax liability.
- Years Until RMDs: This shows how much time you have to plan. A longer runway provides more opportunities for strategic planning, such as Roth conversions.
Strategies to Prepare for RMDs
If your RMDs are still several years away, you have time to plan and potentially reduce their future tax impact.
- Roth Conversions: Converting funds from a Traditional IRA or 401(k) to a Roth IRA can be a powerful strategy. You pay taxes on the converted amount now, but future qualified withdrawals are tax-free, and Roth IRAs have no RMDs for the original owner. This reduces the pre-tax balance that will be subject to RMDs later. Use the Roth Conversion Calculator to see if this makes sense for you.
- Qualified Charitable Distributions (QCDs): Once you reach age 70½, you can donate up to $105,000 (for 2026) per year directly from your IRA to a qualified charity. A QCD counts toward your RMD for the year but is excluded from your adjusted gross income, offering a significant tax advantage.
- Manage Your Tax Bracket: In the years leading up to your RMD start age, you may be in a lower tax bracket. This can be an ideal time to realize income strategically through Roth conversions or other withdrawals to "fill up" lower tax brackets, reducing the likelihood that RMDs will push you into a higher bracket later.
- Plan Withdrawals: Don't just take the minimum. Coordinate withdrawals from different account types (taxable, tax-deferred, and tax-free) to manage your taxable income each year.
Common RMD Age Mistakes
- Applying the Still-Working Exception to IRAs: This is the most common error. The ability to delay RMDs while working only applies to your current employer's 401(k) or similar plan, never to IRAs.
- Ignoring RMDs from Old 401(k)s: If you have 401(k)s from previous jobs, you must start taking RMDs from them at your RMD age, even if you are still working elsewhere.
- Missing the April 1st Deadline Nuance: Delaying your first RMD until April 1st of the next year means taking two distributions in one year, which can significantly increase your taxable income.
- Forgetting RMDs for Each Account: You must calculate the RMD for each of your pre-tax retirement accounts separately. While you can aggregate the total RMD amount for all your Traditional IRAs and take it from a single IRA, you cannot do this between IRAs and 401(k)s.
- Misunderstanding Inherited Account Rules: The 10-year rule for non-spouse beneficiaries is a major change. Failing to empty the account in time can lead to steep penalties.
Frequently Asked Questions
Quick answers to the questions people usually have after running the retirement calculator.
1What is the RMD age for 2026?
Your RMD age is based on your birth year, not the current year. If you were born between 1951 and 1959, your RMD age is 73. If you were born in 1960 or later, your RMD age is 75.
2Did the RMD age change recently?
Yes. The SECURE 2.0 Act of 2022 increased the RMD age. It rose from 72 to 73 starting in 2023 for those born in 1951 or later. It will increase again to 75 for those born in 1960 or later.
3Can I delay RMDs if I'm still working?
You can only delay RMDs from your current employer's 401(k) or 403(b) plan if you are not a 5% owner. This exception does not apply to IRAs or plans from former employers.
4What is the penalty for missing an RMD?
The penalty for failing to take your full RMD is 25% of the amount you should have withdrawn. If you correct the mistake in a timely manner, the penalty may be reduced to 10%.
5Do Roth IRAs have RMDs?
No, original owners of Roth IRAs are not required to take RMDs during their lifetime. As of 2024, Roth 401(k)s are also exempt from RMDs for the original owner under SECURE 2.0. However, beneficiaries who inherit a Roth IRA or Roth 401(k) are typically required to take distributions.
6How is the first RMD calculated?
Your first RMD is calculated by taking your account balance on December 31st of the prior year and dividing it by a life expectancy factor from the IRS's Uniform Lifetime Table. Use the main RMD Calculator for a precise calculation.
7What's the difference between an RMD calculator and an RMD age calculator?
An RMD age calculator, like this one, tells you when you must start taking withdrawals. A standard RMD calculator tells you how much you must withdraw each year.
8Do I have to take RMDs from an inherited IRA?
Yes, in almost all cases. Most non-spouse beneficiaries must withdraw all funds from an inherited IRA within 10 years of the original owner's death. For more details, see our Inherited IRA Calculator.
9Can I do a Roth conversion to avoid RMDs?
Yes. Converting money to a Roth IRA reduces the balance in your traditional accounts that are subject to RMDs. Since Roth IRAs don't have RMDs for the original owner, this is a popular strategy. Explore it with the Roth IRA Conversion Calculator.
10Where can I find the official RMD life expectancy tables?
The IRS provides the official tables in their publications, such as Publication 590-B. Our main RMD Calculator has these tables built-in for your convenience.
