Required minimum distributions can push you into higher tax brackets, trigger Medicare surcharges, and reduce your estate — often with little warning. Understanding your RMD schedule years in advance gives you time to act.
Use the calculator below to see your year-by-year RMD schedule, estimated tax impact, and how much you can reduce future distributions through Roth conversions and other strategies.
Traditional IRAs, 401(k)s, 403(b)s, and most other tax-deferred retirement accounts have been growing tax-free for decades. The IRS eventually requires those deferred taxes to be paid. Starting at age 73 (75 for those born in 1960 or later under SECURE 2.0), you must withdraw a minimum amount each year — calculated using your account balance and an IRS life expectancy table. Miss a distribution and the penalty is steep.
The SECURE 2.0 Act pushed the RMD starting age from 72 to 73 for those born between 1951 and 1959, and to 75 for those born in 1960 or later — giving more time for tax planning and Roth conversions.
Your prior year-end account balance is divided by your life expectancy factor from the IRS Uniform Lifetime Table. The factor decreases each year, meaning a growing percentage of your balance must be withdrawn — and taxed — annually.
Failing to take your full RMD triggers a 25% excise tax on the shortfall — reduced to 10% if corrected within two years. Under prior law the penalty was 50%. Missing distributions is one of the most avoidable and costly tax mistakes in retirement.
Enter your account balance, current age, and tax information. The calculator uses the IRS Uniform Lifetime Table to project your RMD for each year, along with an estimated federal tax impact. Adjust inputs to model different scenarios.

The best time to reduce future RMDs is years before they begin. Several strategies can significantly lower the balance subject to mandatory withdrawals — reducing your tax burden and giving you more flexibility in retirement.
Converting traditional IRA or 401(k) funds to a Roth account before age 73 reduces the balance subject to RMDs. Roth accounts have no RMD requirements during the owner's lifetime. Converting in low-income years — especially the gap between retirement and Social Security — can dramatically reduce future RMD exposure while keeping you in a lower bracket.
Reduces future RMD balanceIf you are 70½ or older, you can donate up to $105,000 per year directly from your IRA to a qualifying charity. QCDs count toward your RMD but are excluded from taxable income — unlike a regular withdrawal followed by a charitable deduction. For charitably inclined retirees this is one of the most tax-efficient strategies available.
Satisfies RMD tax-freeDrawing down traditional accounts in the years between retirement and age 73 — even before RMDs are required — can reduce the balance that will be subject to mandatory distributions. Combined with Roth conversions, this approach can meaningfully lower the size of future RMDs while managing your current tax bracket.
Reduces future RMD balanceIf you are still employed and participating in your current employer's 401(k), you may be able to delay RMDs from that specific plan past age 73 — but only while you remain employed. This does not apply to IRAs or former employer plans. It can provide additional time for planning while you remain in the workforce.
Defers RMD start dateIRMAA — the Income-Related Monthly Adjustment Amount — is an additional Medicare Part B and Part D premium charged to higher-income retirees. Because it is based on your income from two years prior, a large RMD today can increase your Medicare premiums two years from now. This is one of the most overlooked consequences of unplanned RMDs.
Medicare uses your MAGI from two years prior to determine your IRMAA surcharge. A large RMD or Roth conversion in 2025 could affect your Medicare premiums in 2027 — giving you a narrow window to plan ahead.
IRMAA surcharges in 2024 range from an additional $69.90/month to $419.30/month per person for Part B alone, depending on income tier. For a couple, that's up to $10,000 per year in additional premiums — on top of regular Medicare costs.
Keeping RMDs and other income below IRMAA thresholds — through QCDs, careful Roth conversion sizing, and withdrawal sequencing — can preserve tens of thousands in Medicare savings over a long retirement. This requires forward-looking, proactive planning.
RMD planning isn't just about withdrawals — it's about managing a cascade of tax and benefit consequences that most people don't see until it's too late to act.
The window between retirement and age 73 is the most valuable planning opportunity most retirees never use. As fee-only fiduciaries, we model every scenario with no product incentives — just the strategy that's best for you.
