RMD Calculator — Calculate Your Required IRA Withdrawals — USA 2026
Calculate your Required Minimum Distributions from traditional IRA and 401k accounts. See how much you must withdraw each year after age 73.
Required Minimum Distributions are mandatory annual withdrawals from tax-deferred retirement accounts starting at age 73 (increased from 72 by SECURE 2.0 Act). The IRS calculates your RMD by dividing your account balance by a life expectancy factor from their Uniform Lifetime Table. Failing to take your full RMD results in a 25% excise tax on the amount not withdrawn reduced from the previous 50% penalty.
How much is my RMD at age 73?
Your RMD equals your account balance as of December 31 of the prior year divided by the IRS life expectancy factor. At age 73 the factor is 26.5. With a $500000 IRA balance: RMD = $500000 / 26.5 = $18868. This increases each year as the life expectancy factor decreases. At age 80 the factor drops to 20.2 making the RMD approximately $24752 on the same balance.

How Tax Calculation Works
Income tax is calculated on your total taxable income after deducting eligible exemptions and deductions from your gross income. The tax is applied progressively — you pay a lower rate on initial income slabs and higher rates only on income that exceeds each threshold. This means moving into a "higher tax bracket" does not mean your entire income is taxed at the higher rate. Understanding marginal vs effective tax rate is crucial: your marginal rate applies only to the last rupee earned, while your effective rate is the average across all slabs.
Tax-Saving Strategies
Under the old regime, maximize deductions: Section 80C allows up to Rs 1.5 lakh through PPF, ELSS, EPF, and life insurance. Section 80D covers health insurance premiums up to Rs 25,000 (Rs 50,000 for senior citizens). Section 80CCD(1B) offers an additional Rs 50,000 deduction for NPS contributions. Home loan interest up to Rs 2 lakh is deductible under Section 24. Under the new regime, the Rs 75,000 standard deduction and lower slab rates may save you more if your total deductions are below Rs 3.75 lakh. Calculate under both regimes before choosing.

Frequently Asked Questions
How much is my RMD at age 73?
Your RMD equals your account balance as of December 31 of the prior year divided by the IRS life expectancy factor. At age 73 the factor is 26.5. With a $500000 IRA balance: RMD = $500000 / 26.5 = $18868. This increases each year as the life expectancy factor decreases. At age 80 the factor drops to 20.2 making the RMD approximately $24752 on the same balance.
Can I withdraw more than my RMD?
Yes you can always withdraw more than the minimum. The RMD is only the required minimum. However all withdrawals from traditional IRAs and 401ks are taxed as ordinary income. Some retirees strategically withdraw more than the RMD in lower-income years to reduce future RMDs and manage their tax bracket over retirement.
How do Roth accounts handle RMDs?
Roth IRAs have no RMDs during the owner lifetime making them excellent for estate planning and tax-free growth. Roth 401ks previously required RMDs but the SECURE 2.0 Act eliminated this requirement starting in 2024. Converting traditional IRA funds to Roth before age 73 can eliminate future RMDs though you pay income tax on the conversion amount.
What are the US federal tax brackets?
The US uses seven progressive tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Your effective tax rate is the average across all brackets, which is always lower than your marginal rate. Standard deduction for 2026 is approximately $15,000 for single filers and $30,000 for married filing jointly.
How can I reduce my US tax bill legally?
Maximize 401(k) or IRA contributions to reduce taxable income. Contribute to an HSA if eligible. Claim the standard or itemized deduction — whichever is higher. Use tax-loss harvesting to offset capital gains. Consider qualified charitable contributions and education credits.
What is the difference between marginal and effective tax rate?
Your marginal rate is the tax on your last dollar earned. Your effective rate is total tax divided by total income — always lower. For example, at $100,000 income, your marginal rate might be 22% but your effective rate is only about 15% because lower brackets are taxed at 10% and 12%.
