RMD vs. Amortization 72(t) Method: Which Pays More? (w/Examples) + FAQs

Currency note: This article reflects federal rules under IRS Notice 2022-6 and general state-tax conformity as of June 2026, and covers tax year 2026. Tax law changes — confirm current figures before you file. This guide is educational and is not a substitute for advice from a licensed CPA or tax attorney for your specific situation.

Quick Answer

The fixed amortization method almost always pays more — often two to three times as much. For tax year 2026, a 50-year-old with a $500,000 IRA gets about $13,800 a year under the RMD method, but roughly $30,200 a year under amortization at the 5% rate. RMD pays less but flexes yearly.

What This Comparison Really Decides

You are likely staring at a retirement account you cannot touch yet without a 10% penalty, and you need a paycheck from it before age 59½. The choice between the required minimum distribution method and the fixed amortization method is not a small one — it sets the size of every check you receive, and once you start a fixed plan, you are usually locked in for years.

The stakes are real. Pick the wrong method and you either starve your budget or drain your account too fast, and a single misstep can claw back every penalty you avoided, plus interest. According to Fidelity’s overview of the 72(t) rule, these substantially equal periodic payment (SEPP) plans must continue for at least five years or until you turn 59½, whichever is longer — so this is a multi-year commitment, not a one-time withdrawal.

The Three Pieces You Must Understand First

A 72(t) plan — formally a series of substantially equal periodic payments (SoSEPP) — is the IRS escape hatch from the 10% early-withdrawal penalty. Section 72(t) of the tax code adds a 10% additional tax to most retirement-account withdrawals taken before age 59½, on top of regular income tax. The SoSEPP exception under Section 72(t)(2)(A)(iv) lets you skip that 10% penalty if you take a steady, formula-driven stream of payments.

There are three approved ways to set the payment size: the RMD method, the fixed amortization method, and the fixed annuitization method. This guide focuses on the two most-used — RMD and amortization — because annuitization lands very close to amortization and is rarely chosen on its own. All three are spelled out in IRS Notice 2022-6, which replaced the older Revenue Ruling 2002-62 for any plan starting after 2022.

The RMD Method, in Plain English

The RMD method divides your prior year-end account balance by a life-expectancy factor from an IRS table, and you redo that math every single year. Because the balance moves with the market and the factor changes with your age, your payment changes annually — it is never “fixed.” The consequence is built-in flexibility: if your account drops in a bad market, your required payment drops too, which protects the account from over-draining. A common misconception is that “RMD” here means the same rules as the age-73 required minimum distributions retirees take; it does not — it borrows the math, not the age trigger. What to do: choose this method if you want the lowest, safest payment and can live with a check that moves each year.

The Fixed Amortization Method, in Plain English

The fixed amortization method spreads your whole balance over your life expectancy using a chosen interest rate, exactly like paying off a loan in level installments, as the Investopedia explainer on the method describes. You calculate the payment once, and that same dollar amount comes out every year for the life of the plan. The consequence is a bigger, predictable check — but no relief if markets fall, which raises the odds of draining the account. A frequent misconception is that you can tweak the amount when your budget changes; you cannot, without blowing up the plan. What to do: choose amortization when you need maximum income now and want a fixed, plannable number.

The Interest Rate — The Lever That Sets Your Raise

For the amortization (and annuitization) methods, you pick an interest rate that is no more than the greater of 5% or 120% of the federal mid-term rate for one of the two months before your first payment, per the IRS interest-rate rule. A higher allowed rate means a bigger payment, because more “growth” is assumed and front-loaded. The consequence of picking too high a rate is none — as long as you stay at or under the cap; picking too low simply shrinks your check. What to do: in most 2026 cases the flat 5% is the highest you can use, so default to 5% if you want the largest amortization payment.

Which Situation Applies to You?

The “right” method depends entirely on why you are tapping the account early. Use this branch to jump to the math that fits you.

You need the biggest possible paycheck (FIRE, full early retirement): the fixed amortization method at the 5% rate is your answer — see the worked $500,000 example below.
You only need a modest bridge and want safety: the RMD method pays less but self-adjusts and is nearly impossible to “break” on amount.
You need an exact dollar figure, not the maximum: do not force the method — instead split your IRA and run the plan on a smaller balance (the “right-sizing” trick covered later).
You started a fixed plan and now need less: you get one legal escape — a one-time switch from amortization to RMD, explained in the rules section.

Worked Example: $500,000 IRA, Age 50, Tax Year 2026

Meet the core scenario. You are single, turn 50 in 2026, and have a $500,000 IRA balance as of December 31, 2025. You use the Single Life Table from Notice 2022-6, which gives a life-expectancy factor of 36.2 at age 50, and the maximum 5% interest rate for the fixed method.

RMD method: Divide the balance by the life-expectancy factor.

$500,000 ÷ 36.2 = $13,812 for the first year.
Next year you redo it: take the new December 31 balance and divide by the age-51 factor of 35.3, so the payment changes every year.

Fixed amortization method: Divide the balance by an amortization factor built from the 5% rate over 36.2 years. That factor is 16.5804.

$500,000 ÷ 16.5804 = $30,156 every year, fixed for the life of the plan.

The amortization method pays $16,344 more in year one — about 2.2 times the RMD payment. Over a five-year minimum, that is roughly $81,700 more cash in hand (before market changes), which is exactly why income-hungry early retirees lean toward amortization. The trade-off: that fixed $30,156 keeps coming out even if your account falls to $300,000, accelerating depletion.

Same Person, Lower Interest Rate

If the federal mid-term rate forced you to a lower number — say 4% — the amortization factor rises to 18.9559, and your fixed payment falls to $26,377. That is $3,779 less per year than the 5% version, showing how much the rate lever matters. The RMD payment does not use an interest rate, so it stays at $13,812 regardless.

Three Real-World Scenarios

Below are the three most common situations, each as a quick decision aid.

Scenario 1 — Maximize Income for Early Retirement

Your Goal	The Smart Move
Replace a full paycheck before 59½	Use fixed amortization at the 5% rate for the largest check
Keep the math simple and predictable	A fixed annual amount never needs recalculating
Accept market risk on the account	The payment will not shrink if the market drops, so monitor the balance

Scenario 2 — A Modest, Safe Bridge

Your Goal	The Smart Move
Cover a small gap until a pension or 59½	Use the RMD method for the lowest, safest payment
Protect the account in down markets	The payment auto-shrinks when the balance falls
Avoid any chance of over-withdrawing	RMD’s yearly reset makes over-draining far less likely

Scenario 3 — An Exact Dollar Target

Your Goal	The Smart Move
Withdraw a precise amount, not the max	Split the IRA and run amortization on a smaller balance
Keep the rest growing untouched	The untouched IRA stays out of the SEPP and out of the rules
Preserve future flexibility	A second clean IRA can start its own plan later if needed

Named Examples You Can Follow

Maria, 45, FIRE planner, $400,000 IRA. Maria wants to retire fully and needs every dollar. Under the RMD method she gets $9,756 a year (factor 41.0); under amortization at 5% she gets $23,129. She chooses amortization for the higher income but keeps a cash buffer because the fixed payment will not drop in a downturn.

David, 52, laid off, $600,000 IRA. David needs real income for several years until he finds new work. The RMD method pays $17,493; amortization at 5% pays $36,927 (factor 34.3). He picks amortization, knowing his plan must run until he is 59½, not just five years, because that is the later date.

Susan, 57, bridge to a pension, $900,000 IRA. Susan only needs to cover 2.5 years until 59½ and wants safety. The RMD method gives her $30,201; amortization gives $58,720. She chooses the RMD method because she needs less, wants the account protected, and her plan still must run a full five years to December of the fifth year.

The Rules That Can Cost You Everything

The single scariest rule is the modification (or “busted plan”) penalty. If you change your payment amount — taking more or less than the method requires — before the later of five years or age 59½, the IRS recapture tax under Section 72(t)(4) hits. The consequence is severe: you owe the 10% penalty on every dollar you ever pulled under the plan, plus interest for the deferral period. For David above, busting the plan in year three could mean thousands in retroactive penalties plus interest. The misconception is that you can quietly adjust in a tight year; you cannot. What to do: never deviate from the calculated amount, and route any extra cash needs through a separate account outside the SEPP.

You do get one legal escape valve. The IRS allows a single, one-time switch from the fixed amortization (or annuitization) method to the RMD method, and it is not treated as a modification. In the IRS’s own example, Sam switched in 2026 and his payment dropped from $36,251 to $25,641 — a built-in pressure release for anyone whose fixed payment is draining the account too fast. What to do: if your fixed payment is too high, use this one-time switch rather than simply taking less, which would bust the plan.

Federal vs. State: Two Different Questions

The 72(t) exception is a federal rule — it waives the federal 10% early-withdrawal penalty only. It does not touch regular federal income tax (you still owe that on the withdrawal), and it says nothing about your state.

Federal Treatment	State Treatment
Waives the 10% federal penalty if rules are followed	Most states that conform follow the federal penalty waiver, but you must confirm yours
Withdrawal is still federally taxable income	The withdrawal is taxable in most states with an income tax; some exempt retirement income
Same rules in every state	Nine states — including Florida, Texas, and Nevada — have no income tax, so the withdrawal is state-tax-free there

Does your state add its own early-withdrawal penalty? A handful, such as California, impose a separate 2.5% state penalty on early distributions, mirroring the old federal rate. What to do: before you start, check your state revenue department’s rules on early retirement distributions, because a clean federal plan does not guarantee a clean state result.

Pros and Cons of Each Method

Fixed Amortization — Pros

Pays the most up front, because it front-loads your balance over your life expectancy.
Gives a fixed, predictable number you can budget around for years.
Requires no yearly recalculation, so there is less chance of a math error after year one.
Lets you tune the payment by choosing a lower interest rate, because the rate sets the size.
Can later switch once to RMD, because the IRS allows that single change as a safety valve.

Fixed Amortization — Cons

Drains the account faster, because the payment never drops in a downturn.
Offers no flexibility, because changing the amount busts the plan.
Risks running the account dry before the plan ends, because withdrawals stay flat.
Locks in a high rate decision, because you cannot raise the rate later.
Carries higher recapture risk, because a tempting “small change” triggers the tax.

RMD Method — Pros

Protects the account, because the payment falls when the balance falls.
Is nearly impossible to bust on amount, because the figure is whatever the formula says.
Suits modest bridge needs, because it produces the smallest required check.
Adapts to markets automatically, because you recalculate every year.
Reduces depletion risk, because withdrawals scale with the account.

RMD Method — Cons

Pays the least, because the divisor (life expectancy) is large.
Gives an unpredictable check, because it changes every year.
Requires annual recalculation, because each year uses a new balance and factor.
Can rise in a bull market, because a bigger balance means a bigger forced withdrawal.
May not cover your needs, because the low payment can fall short of a full budget.

Do’s and Don’ts

Run all three methods first, because comparing them reveals the best fit, as Morningstar’s SEPP case study recommends.
Use the Single Life Table for a bigger payment, because it gives a smaller divisor than the Uniform Lifetime Table.
Split your IRA before starting, because it lets you target an exact payment and shield the rest.
Keep written proof of your calculation, because you must defend the plan if the IRS asks.
Set up automatic transfers, because consistency proves the payments are “substantially equal.”

Don’t

Don’t roll money into the SEPP account, because additions break the plan.
Don’t take an extra withdrawal from the SEPP IRA, because it triggers the recapture tax.
Don’t stop early, because ending before the later of five years or 59½ busts the plan.
Don’t assume your state follows federal rules, because conformity and penalties vary.
Don’t guess the interest rate, because exceeding the cap can disqualify the calculation.

Deadlines, Timing, and Cost

Your plan must run for the later of five full years or until age 59½ — for a 50-year-old, that means nearly a decade, not five years. Miss that finish line by changing the amount early and the recapture tax plus interest applies to all prior years. Setting up a plan is fast — often a single day to split an IRA and start automated payments — but the commitment is long. Doing the math yourself with a free 72(t) calculator from Bankrate costs nothing; having a CPA design and document the plan typically runs a few hundred to a couple thousand dollars, which is cheap insurance against a busted plan.

Mistakes to Avoid

Taking a payment that differs from the calculated amount — triggers the 10% recapture tax on all prior withdrawals, plus interest.
Ending the plan before the later of five years or 59½ — same recapture tax and interest.
Contributing to or rolling funds into the SEPP IRA — disqualifies the plan and triggers penalties.
Using too high an interest rate — can invalidate the amortization amount and the whole plan.
Aggregating multiple IRAs into one payment — each SEPP must come from its own single account, per the IRS.
Assuming the RMD amount stays the same yearly — it must be recalculated, and skipping that can create a wrong payment.
Ignoring state tax — you can owe state income tax and even a separate state penalty (e.g., 2.5% in California) despite a clean federal plan.

What to Do Next

Pull your exact December 31, 2025 account balance, because every calculation starts there.
Decide the income you actually need, because that drives method and whether to split the IRA.
Run RMD, amortization, and annuitization side by side using the Notice 2022-6 tables.
If amortization, confirm your allowed interest rate (usually 5% in 2026) and lock the figure.
Document the calculation, set automated payments, and report withdrawals using Form 5329 to claim the exception when you file.
Call a CPA or tax attorney before you start if your balance is large or your state rules are unclear, because a busted plan is expensive to fix.

FAQs

Which 72(t) method pays the most? The fixed amortization method. It front-loads your balance over your life expectancy at up to a 5% rate, producing payments often two to three times larger than the RMD method for the same balance and age in 2026.

Can I switch from amortization to the RMD method? Yes. The IRS allows a single, one-time switch from the fixed amortization or annuitization method to the RMD method, and it is not treated as a modification. The reverse switch is not allowed.

What interest rate can I use for the amortization method? No more than the greater of 5% or 120% of the federal mid-term rate for one of the two months before your first payment, for plans in 2026. In most cases the flat 5% is the highest available.

Does the RMD method payment change every year? Yes. You recalculate it annually using your prior year-end balance and a new life-expectancy factor for your current age, so the payment moves up or down with your account each year.

How long must my 72(t) plan last? The later of five years or age 59½. A 50-year-old must continue nearly ten years; a 57-year-old still runs a full five years even though 59½ arrives sooner.

What happens if I break the 72(t) rules? You owe a retroactive 10% penalty. The recapture tax applies the 10% penalty to every dollar withdrawn under the plan in all prior years, plus interest for the deferral period.

Do I still pay income tax on 72(t) withdrawals? Yes. The 72(t) exception waives only the 10% early-withdrawal penalty. The withdrawals are still ordinary taxable income on your federal return and, in most states, on your state return.

Can I use a 401(k) for a 72(t) plan? Yes, but usually after separating from service. Many people roll the 401(k) into an IRA first because IRAs offer more flexibility to split balances and right-size the payment.

Can I take the annual amount monthly instead? Yes. The IRS lets you split the annual SEPP amount into monthly, quarterly, or annual installments, as long as the total for the year equals the calculated annual amount.

Which life expectancy table gives the biggest payment? The Single Life Table. It uses a smaller divisor than the Uniform Lifetime Table, so it produces a larger annual payment under both the RMD and amortization methods.

Can I right-size my payment without using my whole IRA? Yes. Split your IRA before starting, then run the SEPP on a smaller, separate account. The untouched IRA stays outside the plan and keeps growing.

Does my state waive the early-withdrawal penalty too? Usually, but confirm it. Most conforming states follow the federal penalty waiver, but a few — such as California with a 2.5% penalty — apply their own rules, so check your state revenue agency.
