How the calculator works

Federal tax: The withdrawal is added to your other income. We calculate income tax on your income alone, then on income + withdrawal, and the difference is the federal tax attributable to the withdrawal — the true marginal cost.

State tax: Applied at each state's approximate income tax rate. No-income-tax states (TX, FL, WA, etc.) show $0 state tax.

10% penalty: Applied to the full withdrawal amount for traditional accounts if you're under 59½ and no exception applies. For Roth 401(k), only the earnings portion is penalized.

Opportunity cost: What you give up in future growth — calculated as the difference between the gross amount left invested vs. the net received, both compounded at 7%/year for the years until retirement.

Common Questions About Early 401(k) Withdrawals

How much does a $25,000 withdrawal actually cost?
At a $70,000 income, a $25,000 withdrawal from a traditional 401(k) before 59½ typically costs: $2,500 penalty (10%) + ~$5,500 federal income tax (22% bracket on the marginal portion) + state tax. Depending on your state, total cost is $8,000–$12,000. You'd net roughly $13,000–$17,000. The opportunity cost of losing $25,000 for 20 years at 7% is ~$97,000.
Is a 401(k) loan better than an early withdrawal?
Almost always yes. A 401(k) loan: (1) avoids the 10% penalty entirely, (2) avoids income tax on the amount (you pay yourself back with after-tax money), (3) lets the remaining balance stay invested, and (4) must be repaid within 5 years (or sooner if you leave your employer). The downside: if you leave your job, the loan is typically due within 90 days or it becomes a taxable distribution.
What if I'm laid off at 55 — does the Rule of 55 apply?
Yes. The Rule of 55 applies if you separate from your employer (retire, quit, or are laid off) in or after the year you turn 55. Being laid off counts. However, it only applies to the 401(k) plan of the employer you're leaving — not to IRAs or to old 401(k) plans from previous employers. You still owe income tax.
Can I use the calculator for a Traditional IRA?
Yes — the same 10% penalty and income tax rules apply to traditional IRAs. Select 'Traditional IRA' in the account type dropdown. Note: the Rule of 55 does NOT apply to IRAs (it's 401(k) plans only). IRAs do have a few additional exceptions not available to 401(k) plans, such as first-time homebuyer ($10,000 lifetime limit) and higher education expenses.

Four new penalty exceptions SECURE 2.0 added to the §72(t) list — emergency personal expense, domestic abuse, terminal illness, and long-term care distributions (2024–2026)

Source: SECURE 2.0 Act §§115, 314, 326, 334; IRS Notice 2024-55; IRS Notice 2026-33; IRS.gov Retirement Topics — Exceptions (updated 2026)

The existing exceptions table (Rule of 55, SEPP, disability, etc.) has four new additions thanks to SECURE 2.0. These are plan-optional — your employer must choose to adopt them via plan amendment (deadline December 31, 2026). Even with these exceptions, ordinary income tax is always owed; only the 10% penalty is waived.

Emergency personal expense distributions

IRC §72(t)(2)(I) — effective Jan 1, 2024

  • Up to $1,000 per calendar year (not indexed for inflation)
  • For unforeseeable or immediate personal or family emergency expenses
  • Participant self-certifies eligibility — plan can rely on written self-certification
  • Only 1 emergency distribution per calendar year
  • Cannot take another for 3 years unless the prior one has been repaid in full or contributions equal the unpaid amount
  • Repayable to the plan within 3 years of receipt
  • Plan adoption optional — requires amendment by Dec 31, 2026

Domestic abuse victim distributions

IRC §72(t)(2)(K) — effective Jan 1, 2024

  • Up to the lesser of $10,000 (indexed for inflation) or 50% of vested account balance
  • Must be a victim of domestic abuse by a spouse or domestic partner
  • Available within the 1-year period beginning on any date of an incident
  • Participant self-certifies (plan can rely on written self-certification)
  • Repayable to the plan within 3 years of receipt
  • Plan adoption optional — requires amendment by Dec 31, 2026

Terminal illness distributions

IRC §401(k)(2)(B)(i)(I) — effective 2024

  • For terminally ill employees certified by a physician
  • Terminal illness means a medically determinable condition expected to result in death within 84 months (7 years)
  • No dollar limit — full account balance can be accessed penalty-free
  • No repayment requirement
  • Applies to 401(k) plans (and certain other qualified plans) — check with your plan administrator
  • Income tax still owed on traditional (pre-tax) balances

Qualified long-term care distributions

IRC §72(t)(2)(N) — effective Dec 29, 2025 (IRS Notice 2026-33)

  • Annual limit: least of $2,600 (2026, indexed), 10% of vested account benefit, or actual LTC premium cost
  • Must be used to pay qualified long-term care insurance premiums
  • Participant must provide a long-term care premium statement to the plan
  • Not subject to mandatory 20% federal withholding (unlike regular distributions)
  • Not an eligible rollover distribution — no direct rollover required
  • Plan adoption optional; requires plan amendment
Important: All four exceptions are plan-optional. Your employer must adopt them by plan amendment (deadline December 31, 2026). If your plan hasn't adopted them, these exceptions are NOT available to you — verify with your HR or plan administrator. Income tax is owed in all cases.

SEPP/72(t) deep dive: RMD vs fixed amortization vs fixed annuitization — how payments are calculated, the retroactive modification trap, and the one-time switch allowed by IRS Notice 2022-6

Source: IRC §72(t); IRS Notice 2022-6; IRS.gov Substantially Equal Periodic Payments; Kitces.com analysis of Notice 2022-6

A SEPP (Substantially Equal Periodic Payment) plan lets you access any IRA or 401(k) penalty-free before 59½ — but it requires a long-term, legally binding commitment. Breaking the rules even once triggers the retroactive recapture tax under IRC §72(t)(4): the 10% penalty on every prior SEPP distribution, plus interest. IRS Notice 2022-6 governs the current rules.

MethodHow payments are calculatedPayment levelRecalculated each year?Best for
RMD methodAccount balance ÷ IRS life expectancy factor (from Uniform Lifetime Table or Single Life Table) — recalculated each year with prior Dec 31 balanceLowest — decreases if balance dropsYes — annual recalculationWant minimum income; preserve account balance; want to switch to later
Fixed amortizationBalance amortized over chosen life expectancy at an interest rate ≤ greater of 5% or 120% of federal mid-term rate — fixed once setHigher — fixed payment for life of SEPPNo — same amount every yearNeed predictable, higher income; won't need to reduce payments
Fixed annuitizationAccount balance ÷ annuity factor (IRS mortality table + permitted interest rate) — fixed once setSimilar to amortization; slightly different calculationNo — same amount every yearWant actuarially-based fixed income; similar use case to amortization

The modification trap — retroactive recapture tax (IRC §72(t)(4))

  • A modification occurs if you take more or less than the calculated annual amount, make additional withdrawals, or roll in new money that changes the account balance after the valuation date
  • Penalty: 10% on ALL prior SEPP distributions made since inception, plus interest at the federal underpayment rate
  • The SEPP must continue for 5 years OR until age 59½, whichever is longer — a 45-year-old starting a SEPP is locked in until 59½ (14.5 years), not just 5 years
  • Exception: if the account balance reaches zero while strictly following the method, this is not a modification — no recapture tax

IRS Notice 2022-6: the one-time method switch and updated interest rate floor

  • One-time switch: if you started with fixed amortization or fixed annuitization, you may switch to the RMD method exactly once in any subsequent year — reducing payments going forward without triggering penalties
  • Once you switch to RMD, you cannot switch back or to any other method (that would be a modification)
  • Interest rate floor raised: Notice 2022-6 set the maximum permitted interest rate for amortization/annuitization at the greater of 5% or 120% of the federal mid-term rate — up from just 120%, enabling higher payment amounts when mid-term rates are low
  • Practical implication: higher permitted interest rates = higher fixed payments = more income if you need it, without requiring a larger account balance

The true long-term cost of early withdrawal: what $10,000–$100,000 taken at ages 30–55 costs in foregone retirement wealth at age 65 — plus the 60-day rollover rule and the 401(k) loan double-tax trap

Source: Compound growth at 7%/yr (S&P 500 historical average); IRS 20% mandatory withholding rule; IRC §72(p) 401(k) loan rules

The penalty and income tax are painful but finite. The compound growth you permanently forfeit is usually the largest cost — and it grows exponentially the younger you are when you withdraw.

Foregone retirement balance at 7%/yr compound growth (S&P 500 historical average). This is what the gross withdrawal amount would have grown to by age 65 if left invested — before any penalty or taxes on the withdrawal itself.

The 60-day rollover rule: how to reverse a distribution and save the penalty + taxes

  • If you take a direct distribution, you have 60 days to deposit the full gross amount (not net) into an IRA or new 401(k) to treat it as a tax-free rollover
  • The plan withholds 20% for federal taxes — you must fund that gap from personal savings to roll over the full gross amount; the 20% withheld will be refunded when you file your return
  • Example: $50,000 distribution → plan sends you $40,000 (withholds $10,000). To complete the rollover within 60 days you must deposit $50,000; you reclaim the $10,000 as a tax refund
  • Requesting a direct rollover (plan transfers funds directly to the new account) avoids the 20% withholding entirely — the safest option

The 401(k) loan double-tax trap if you default

A 401(k) loan is the best alternative to early withdrawal — but defaulting creates a tax nightmare:

  • You repaid the loan with after-tax dollars. If you leave your job or miss payments, the outstanding balance is treated as a taxable distribution — you pay income tax again on the same money
  • If you're under 59½, the defaulted balance also incurs the 10% early withdrawal penalty
  • SECURE 2.0 extended the loan repayment deadline: if you leave your employer, you now have until the tax return due date (including extensions) to roll over the outstanding loan balance to an IRA to avoid the tax and penalty

The penalty, federal tax, state tax, net received, and opportunity cost figures above come from the withdrawal amount and income you enter—not a third-party feed. We add the withdrawal to your ordinary income, compute the marginal federal and state tax attributable to that lump sum, apply the 10% early-withdrawal penalty when it applies, and estimate how much compound growth you forfeit if you had left the money invested. Below are the formulas, the order we follow, and worked examples you can check by hand.

Order of operations

1

Determine the taxable portion

Traditional: full amount · Roth: withdrawal minus contribution basis

Traditional 401(k) and IRA withdrawals are fully taxable as ordinary income. For Roth 401(k), only the earnings portion above your after-tax contribution basis is taxable and subject to penalty.

2

Apply the 10% early-withdrawal penalty

Penalty = 10% × penalty base unless age 59½+ or exception selected

If you are under 59½ and no IRS exception applies, we charge a 10% penalty on the full traditional withdrawal or on Roth earnings only. Selecting an exception (Rule of 55, disability, SEPP, etc.) or reaching age 59½ waives the penalty—but income tax still applies to taxable amounts.

3

Compute marginal federal income tax

Federal tax = tax(with withdrawal) − tax(without withdrawal)

We use 2026 federal brackets and the standard deduction for your filing status. The withdrawal stacks on top of your other income, so we calculate tax on your income alone, then on income plus the taxable withdrawal—the difference is the federal tax attributable to this distribution.

4

Compute marginal state (and NYC city) tax

State tax = state(with withdrawal) − state(without withdrawal)

State tax uses the same marginal method with each state's progressive brackets. No-income-tax states (TX, FL, WA, etc.) show $0. New York City residents also pay city income tax on the marginal portion.

5

Total cost and net received

Total cost = penalty + federal + state · Net = withdrawal − total cost

The effective cost rate shows what share of the withdrawal you lose immediately to taxes and penalty. This does not include plan withholding (typically 20% federal)—that is a prepayment settled on your tax return.

6

Estimate opportunity cost

FV if left invested at 7%/yr − FV of net received at 7%/yr

If you had left the full gross withdrawal in the account until retirement, it would compound at 7% per year. Instead you receive only the net after taxes. The difference in future value is the long-term wealth you forfeit—not just the immediate penalty and taxes.

Worked example

$25,000 traditional 401(k) withdrawal, $70,000 income, TX, age 42

10% × $25,000 = $2,500 penalty

Federal: tax($95,000 − $16,100 deduction) − tax($70,000 − $16,100) = $5,500 (22% marginal bracket)

State (TX): no state income tax

$2,500 + $5,500 + $0 = $8,000 total cost → $17,000 net received (32.0% effective cost)

Opportunity cost over 20 years at 7%: $25,000 × 1.07^20 − $17,000 × 1.07^20 = $30,957 foregone

Opportunity cost (20 yrs)$30,957

Roth 401(k): $25,000 Roth 401(k) withdrawal with $20,000 contribution basis — only $5,000 earnings taxed → penalty $500, federal tax $1,100, net received $23,400.

Rule of 55: $25,000 withdrawal at age 55 with Rule of 55 exception — penalty waived, tax still owed → total cost $5,500 (penalty $0, federal tax $5,500).

Frequently Asked Questions
Early 401(k) withdrawal rules, exceptions, and tax implications.

The IRS levies a 10% penalty on distributions from traditional 401(k) and IRA accounts taken before age 59½. This is in addition to ordinary income taxes. On a $25,000 withdrawal, you'd pay $2,500 in penalty alone — before a dollar of income tax. The total cost can easily reach 35–45% of the withdrawal.

If you leave your job (retire, quit, or are laid off) in or after the year you turn 55, you can withdraw from that employer's 401(k) or 403(b) penalty-free. Key limits: (1) applies only to the plan of your most recent employer, not to IRAs or old 401(k)/403(b) plans, and (2) income tax is still owed. Qualified public safety employees (firefighters, police, EMS) qualify at age 50 under a separate IRS exception.

Substantially Equal Periodic Payments (SEPP), also called 72(t), lets you withdraw penalty-free before 59½ if you commit to fixed annual payments for 5 years or until age 59½ — whichever is longer. The payment amount is calculated using IRS-approved methods (required minimum distribution, fixed amortization, or fixed annuitization). Modifying or stopping the payments early triggers the penalty retroactively, so this is a serious commitment.

A Roth 401(k) has two layers: your own contributions (after-tax money you put in) and earnings (investment growth). Contributions can always be withdrawn tax-free and penalty-free. The 10% penalty only applies to the earnings portion if withdrawn before age 59½ and before the 5-year rule is met. Enter your contribution basis in the calculator to see the exact breakdown.

Consider: (1) 401(k) loan — borrow up to $50,000 or 50% of your vested balance, repaid with interest to yourself; (2) Hardship distribution — for specific circumstances like medical expenses or preventing eviction; (3) Personal loan or HELOC — no retirement savings lost; (4) Roth IRA contribution withdrawal — always tax/penalty-free; (5) SEPP/72(t) — if you're retiring early and need regular income. A 401(k) loan is usually the best option if you need access to cash short-term.

Plan administrators withhold a mandatory 20% for federal taxes from most 401(k) distributions. This is a prepayment toward your actual tax liability. If your actual tax + penalty is more than 20%, you'll owe at tax time. If less, you get a refund. State withholding varies by state. The 10% penalty itself is not typically withheld — it's calculated on your tax return.

Traditional IRAs have the same 10% penalty for distributions before 59½ and many of the same exceptions. Key differences: (1) The Rule of 55 does NOT apply to IRAs; (2) IRA SEPP payments must be maintained for 5 years or until 59½, whichever is longer; (3) First-time homebuyer withdrawals ($10,000 lifetime limit) are penalty-free from IRAs but not 401(k) plans; (4) Higher education expenses are penalty-free from IRAs.
