RMD Calculator-Planning your retirement income is important, especially when you have money saved in a traditional IRA or 401(k). As you get older, the IRS may require you to withdraw a minimum amount from certain retirement accounts each year. This amount is called a Required Minimum Distribution, or RMD.Use our free conversion tools to quickly convert units and measurements without Marriage Tax Calculator manual calculations.

Our RMD Calculator helps you estimate how much money you may need to withdraw from your retirement account for the year. You can use it to understand your required withdrawal, plan your retirement income, and avoid missing an important deadline.
Whether you have a traditional IRA, SEP IRA, SIMPLE IRA, or an eligible employer retirement plan, understanding RMD rules can help you manage your savings more confidently.
In this guide, you will learn how to calculate your RMD, when withdrawals must begin, which IRS life expectancy table to use, and what happens if you miss a required distribution.
What Is an RMD Calculator?
An RMD Calculator is a retirement planning tool that estimates your required minimum distribution from certain tax-deferred retirement accounts.
RMD stands for Required Minimum Distribution. It is the minimum amount that eligible retirement account owners must generally withdraw each year after reaching the applicable starting age.
The amount depends mainly on two things:
- Your retirement account balance at the end of the previous year.
- Your applicable life expectancy factor from the IRS tables.
For example, if your eligible retirement account had a balance of $300,000 on December 31 of the previous year, and your applicable IRS distribution factor is 26.5, your estimated RMD would be about $11,320.75.
The actual amount depends on the factor that applies to your age, account type, and beneficiary situation.
An RMD calculator can make this calculation easier without requiring you to work through the IRS tables manually.
How to Use Our RMD Calculator
Follow these steps to estimate your required minimum distribution.
- Enter your retirement account balance: Use the account balance as of December 31 of the previous year.
- Select the distribution year: Choose the year for which you need to calculate your RMD.
- Enter your age: Use your age on your birthday during the distribution year, where applicable under the IRS rules.
- Choose the correct account type: Select your traditional IRA, 401(k), or other supported retirement account.
- Select the applicable IRS table: Most account owners use the Uniform Lifetime Table. Some people must use a different table.
- Enter your distribution factor: If the calculator does not automatically select the correct factor, enter the factor from the applicable IRS table.
- Calculate your RMD: Review the estimated annual withdrawal.
For a more reliable result, make sure the calculator uses the correct IRS table and current rules. Inherited retirement accounts and certain employer plans may follow different requirements.
RMD Formula: How to Calculate Required Minimum Distribution
The basic RMD formula is straightforward.
RMD = Previous Year-End Account Balance ÷ IRS Distribution Period Factor
The previous year-end account balance is generally the value of your retirement account on December 31 of the year before the withdrawal year.
The distribution period factor comes from the applicable IRS life expectancy table.
RMD Calculation Example
Suppose you have a traditional IRA and want to calculate your RMD for 2026.
Your details are:
- IRA balance on December 31, 2025: $300,000
- Applicable IRS distribution factor: 26.5
- Distribution year: 2026
Using the formula:
RMD = $300,000 ÷ 26.5
Estimated RMD = $11,320.75
You would generally need to withdraw at least the applicable required amount for the year, subject to the rules for your account.
The factor of 26.5 is used here only to demonstrate the calculation. Your actual factor must come from the correct IRS table for your age and circumstances.
When Do RMDs Start in 2026?
The age at which you must begin taking required minimum distributions depends on your birth year and the applicable rules.
Under current federal rules, many traditional IRA and retirement plan owners must begin RMDs at age 73. For people born in 1960 or later, the applicable starting age is generally 75.
The first distribution deadline can differ from the deadlines for later years.
RMD Starting Age by Birth Year
| Birth year | General RMD starting age |
|---|---|
| 1950 or earlier | Earlier rules may apply |
| 1951–1959 | 73 |
| 1960 or later | 75 |
This table is a general guide. Special rules may apply depending on your account type, employment status, and retirement plan.
When Is Your First RMD Due?
Your first RMD is generally due by April 1 of the year after the year you reach your applicable starting age.
For example, if your first RMD year is 2026, you may generally delay that first withdrawal until April 1, 2027.
However, if you use this option, you will usually need to take your second RMD by December 31, 2027. That means two taxable distributions may fall in the same calendar year.
For this reason, it is worth considering the potential tax impact before delaying your first RMD.
After the first year, RMDs are generally due by December 31 each year.
What Is the IRS RMD Table?
The IRS publishes life expectancy tables to help retirement account owners and beneficiaries calculate required minimum distributions.
The appropriate table depends on your circumstances.
1. Uniform Lifetime Table
The Uniform Lifetime Table is used by most retirement account owners calculating their own RMDs.
It generally applies when your spouse is not your sole designated beneficiary or your spouse is not more than 10 years younger than you.
To calculate your RMD, find the factor beside your age in the applicable distribution year and divide your previous year-end account balance by that factor.
2. Joint and Last Survivor Expectancy Table
The Joint and Last Survivor Expectancy Table is generally used when your spouse is your sole designated beneficiary and is more than 10 years younger than you.
This table considers both your age and your spouse’s age. It often produces a larger distribution factor, which can result in a smaller required withdrawal.
3. Single Life Expectancy Table
The Single Life Expectancy Table is used in certain inherited retirement account situations.
The rules depend on who inherited the account, when the original owner died, and whether the beneficiary qualifies for a special exception.
Inherited IRA RMD calculations can be more complicated than calculations for an original account owner, so use the applicable IRS guidance.
RMD Calculation Examples for Different Account Balances
The following examples show how the RMD formula works with different retirement account balances.
For illustration, assume an applicable distribution factor of 25.5 in every example. This is a hypothetical factor, not a claim that 25.5 applies to every person.
| Previous year-end balance | Example factor | Estimated RMD |
|---|---|---|
| $100,000 | 25.5 | $3,921.57 |
| $200,000 | 25.5 | $7,843.14 |
| $300,000 | 25.5 | $11,764.71 |
| $500,000 | 25.5 | $19,607.84 |
| $750,000 | 25.5 | $29,411.76 |
| $1,000,000 | 25.5 | $39,215.69 |
These examples are designed to explain the formula. Your real RMD should be calculated using the factor that applies to your situation.
RMD Calculator for a Traditional IRA
A traditional IRA is an individual retirement account that can provide tax advantages for retirement savings.
Traditional IRA owners generally must take RMDs starting at the applicable required age. The distribution is usually included in taxable income, except for amounts that represent a return of after-tax basis or otherwise qualify for different treatment.
To estimate your traditional IRA RMD, you generally need:
- Your account balance on December 31 of the previous year.
- Your age during the distribution year.
- The applicable IRS distribution factor.
- Any special circumstances affecting the calculation.
If you own multiple traditional IRAs, you generally calculate the RMD separately for each account. You can usually take the combined amount from one or more of your traditional IRAs.
However, do not assume that you can combine required withdrawals across different types of retirement plans. Employer plans often have separate distribution requirements.
RMD Calculator for a 401(k)
A 401(k) is an employer-sponsored retirement savings plan. Traditional 401(k) accounts are generally subject to RMD rules.
For a 401(k) RMD calculation, use the account balance and applicable IRS factor for the distribution year.
One important difference is that RMDs from 401(k) accounts generally must be satisfied separately for each plan. The rules are not identical to those for multiple traditional IRAs.
If you are still working for the employer sponsoring the plan, you may qualify for an exception that delays RMDs from that employer’s plan until retirement. This exception generally does not apply to an account in a former employer’s plan and does not apply in the same way to IRAs. The plan’s rules and ownership circumstances matter.
Designated Roth 401(k) accounts are no longer subject to lifetime RMDs for the original account owner under the rules effective from 2024. Beneficiaries can still have distribution requirements.
RMD Rules for Roth IRA Accounts
One common question is whether Roth IRA owners need to take required minimum distributions.
The original owner of a Roth IRA generally does not have to take RMDs during their lifetime.
This is different from a traditional IRA, where required minimum distributions usually apply once the owner reaches the applicable starting age.
However, inherited Roth IRAs can be subject to distribution rules. The requirements depend on the beneficiary and other circumstances.
Do not assume that every account described as a Roth account follows identical rules. Check the account type and the current IRS guidance before deciding whether a withdrawal is required.
Are RMDs Taxable?
Required minimum distributions from traditional tax-deferred retirement accounts are generally taxable as ordinary income, except for amounts that qualify for different treatment.
For example, a traditional IRA distribution may be partly or fully taxable depending on your contributions, tax basis, and other circumstances.
RMDs themselves are not subject to the 10% additional tax that can apply to certain early retirement account distributions. However, the distribution can increase your taxable income and may affect other tax calculations.
A qualified Roth IRA distribution is generally tax-free, but inherited account rules and other exceptions must be considered.
An RMD calculator estimates the amount you need to withdraw. It does not automatically determine your final tax liability.
What Happens If You Do Not Take Your RMD?
Failing to withdraw the required amount by the applicable deadline can result in an excise tax.
Under current federal rules, the standard excise tax on an RMD shortfall is generally 25% of the amount that should have been withdrawn but was not.
The tax may be reduced to 10% if the shortfall is corrected within the applicable correction window. Other relief may be available in qualifying circumstances, depending on the facts and applicable IRS procedures.
Example of a Missed RMD
Suppose your required RMD is $10,000, but you withdraw only $7,000 by the deadline.
Your shortfall is:
$10,000 − $7,000 = $3,000
At the standard 25% excise tax rate, the potential tax on the shortfall would be:
$3,000 × 25% = $750
This is an illustration of the standard calculation, not a determination of your actual tax. Correction rules and eligibility for relief may change the outcome.
If you miss an RMD, contact your retirement account provider or a qualified tax professional promptly. You may need to take the remaining distribution and file the appropriate IRS form.
How Can You Plan Your RMD Withdrawals?
Planning ahead can make retirement withdrawals easier to manage.
Review Your Retirement Accounts
Check your traditional IRAs, employer retirement plans, and other relevant accounts. Make sure you understand which accounts require separate RMD calculations.
Estimate Your RMD Before the Deadline
Use your previous year-end balances and the correct IRS distribution factors to estimate your required withdrawals early in the year.
Consider Your Tax Bracket
An RMD can increase your taxable income. Consider how withdrawals may affect your federal income tax, state income tax, and other income-related calculations.
Coordinate Withdrawals With Other Retirement Income
Social Security, pension income, investment income, and retirement account distributions can all affect your overall financial picture.
A retirement income plan can help you decide how to use your RMD while managing your other income sources.
Keep Records of Your Withdrawals
Save statements and distribution confirmations. These records can help you verify that you satisfied your annual RMD requirement.
Frequently Asked Questions About RMD Calculators
1. What is an RMD calculator?
An RMD calculator estimates the minimum amount you must withdraw from an eligible retirement account each year. It uses your previous year-end account balance and the applicable IRS distribution factor.
2. How do I calculate my RMD for 2026?
Start with the eligible account balance on December 31, 2025. Divide that amount by the applicable IRS life expectancy factor for 2026. Make sure you use the correct table for your account and circumstances.
3. What is the RMD formula?
The general formula is:
RMD = December 31 Previous-Year Account Balance ÷ Applicable IRS Distribution Factor
Special rules may apply to inherited accounts and certain employer plans.
4. At what age do RMDs start?
Many retirement account owners begin RMDs at age 73. For people born in 1960 or later, the general starting age is 75. Your exact requirement depends on the applicable law and account type.
5. Can I delay my first RMD?
You can generally delay your first RMD until April 1 of the year after the year you reach your applicable starting age. If you do, you will usually need to take a second RMD by December 31 of that same year.
6. Are RMDs required from Roth IRAs?
The original owner of a Roth IRA generally does not have lifetime RMDs. Inherited Roth IRAs can be subject to required distributions.
7. Are RMDs taxable?
Traditional IRA and traditional retirement plan RMDs are generally taxable as ordinary income, except for amounts that qualify for different treatment. The final tax amount depends on your circumstances.
8. Can I combine RMDs from multiple IRAs?
You generally calculate the RMD separately for each traditional IRA, but you can usually withdraw the combined amount from one or more of those IRAs. Different rules apply to many employer retirement plans.
9. Can I combine my IRA and 401(k) RMDs?
Generally, no. IRA aggregation rules do not automatically allow you to satisfy a 401(k) RMD by withdrawing money from an IRA. Employer plans usually have their own requirements.
10. What happens if I miss an RMD deadline?
A shortfall can trigger an excise tax. The standard rate is generally 25% of the amount not withdrawn, with a possible reduction to 10% when the applicable correction requirements are met.
11. Does a 401(k) have RMD rules?
Traditional 401(k) accounts generally have RMD requirements. An exception may apply while you are still working for the sponsoring employer, subject to plan rules and other conditions. Designated Roth 401(k) accounts are generally exempt from lifetime RMDs for the original owner beginning in 2024.
12. Which IRS table should I use for my RMD?
Most original account owners use the Uniform Lifetime Table. If your spouse is your sole beneficiary and more than 10 years younger, you may need the Joint and Last Survivor Expectancy Table. Certain beneficiaries use the Single Life Expectancy Table.
13. Does my RMD change every year?
Your RMD can change each year because your previous year-end account balance and applicable distribution factor may change. Market gains, losses, contributions, and withdrawals can affect your account balance.
14. Can I withdraw more than my RMD?
You can generally withdraw more than the required minimum, subject to your account’s distribution rules. However, taking extra money in one year usually does not count toward the next year’s RMD.
15. Can I reinvest my RMD?
You may be able to invest money after taking a required distribution, subject to the rules of the investment account and any applicable tax requirements. You generally cannot roll an RMD itself into another tax-deferred retirement account.
16. Is an RMD calculator accurate?
An RMD calculator can provide a useful estimate when it uses the correct account balance, IRS table, distribution year, and account rules. Always confirm the result with your retirement plan provider or a qualified tax professional when your circumstances are complex.
