A FIRE number is usually spending divided by a 4 % withdrawal rate, 25 times what you spend. That is where most calculators stop, and it leaves three costs out. Withdrawals from a 401(k) or a traditional IRA are taxed: on $60,000 of spending with most savings pre-tax, a single filer needs about $2,306 more each year for federal tax in 2026, which adds $57,651 to the target. Health insurance has to be bought until Medicare at 65: twenty years of a $7,200 premium is worth $94,214 at the start. And money in pre-tax accounts carries a 10 % additional tax before age 59½ unless the rule of 55, a 72(t) series, a Roth conversion ladder or a governmental 457(b) opens it. The calculator above applies those rules year by year. With its default figures, the plain 25× rule says age 49; once tax, health and access are counted, the answer is 50.

Why 25 times your spending is not your FIRE number

The 4 % rule comes from research on 30-year retirements that started at 65 and drew from a mixed portfolio. It says nothing about who owns the money, how it is taxed or when the law lets it out. For someone stopping at 45 with most savings in a 401(k), those three questions decide more than the withdrawal rate does.

Tax. A dollar in a traditional 401(k) is not a dollar to spend. In 2026 the standard deduction is $16,100 for a single filer and $32,200 for a married couple, then the brackets start at 10 % and 12 % (Rev. Proc. 2025-32). Long-term gains from a taxable account are taxed at 0 % up to $49,450 of taxable income for a single filer. Early retirees often pay little tax, but rarely none, and the amount depends on the mix of accounts.

Health insurance. Medicare starts at 65 (Medicare.gov). Before that, coverage comes from COBRA for up to 18 months at as much as 102 % of the full premium, from a spouse's employer, or from the Marketplace. The premium tax credit depends on the income you report, which an early retiree partly chooses: a single person with $40,000 of income in 2026 and a $700 benchmark premium gets $413 a month of credit. Above 400 % of the poverty line, the credit stops entirely.

Access. The IRS lists the exceptions to the 10 % additional tax on early distributions (irs.gov). Four of them build a retirement bridge: separation from service in or after the year you turn 55, substantially equal periodic payments, Roth contributions and seasoned conversions, and the governmental 457(b), which owes no 10 % at all. The rest (disability, medical bills, a first home) help in a crisis, not in a plan.

Which account opens when

Roth conversionsfive tax years after each oneno (taxed at conversion)

401(k) or 403(b) of the job you leaveif you leave in or after the year you turn 55yes
Older 401(k)s and IRAsthrough a 72(t) seriesyes

The order matters as much as the amounts. The bridge spends taxable money and Roth contributions first, then the accounts the rules open one after the other. A person retiring at 50 with everything in a 401(k) has two options: a 72(t) series, which fixes a yearly amount for at least five years, or a conversion ladder, which needs five years of other money before the first rung can be spent. In the default case above, choosing the ladder moves the earliest age to 50.

The rate for a 72(t) series changes every month. For a first payment in November 2026, the highest rate allowed is 5.54 %: the greater of 5 % and 120 % of the federal mid-term rate of the two months before (monthly table).

Tax on withdrawals

Before you hand in your notice

Check what your plan allows after you leave

The tax code allows a penalty-free payout under the rule of 55; it does not oblige your plan to make partial payments. Some plans let a former employee take any amount at any time, others pay only a lump sum or fixed installments. A lump sum lands on one tax return and can push the whole balance through the 22 % and 24 % brackets. Read the summary plan description before you give notice, and ask the administrator in writing. If partial withdrawals are not allowed, rolling part of the balance to an IRA keeps the tax spread out but loses the rule of 55 on that part.

Count the years until 59½ and until 65

Two dates shape an early retirement in the United States. At 59½ every 401(k) and IRA opens without the 10 % additional tax. At 65 Medicare replaces private health insurance. Someone stopping at 48 has eleven and a half years of bridge to fund from reachable money and seventeen years of premiums. The bridge calculator measures the first gap; the Marketplace calculator prices the second.

Decide your income before the Marketplace does

Marketplace premiums depend on modified adjusted gross income, and an early retiree largely decides it: taxable account sales count only for their gain, Roth contributions and seasoned conversions do not count at all, while 401(k) withdrawals and Roth conversions count in full. In 2026 and 2027 the credit stops at 400 % of the poverty line, $84,600 for two people in 2026. A large conversion in a year of Marketplace coverage can cost more in lost credit than it saves in future tax. The cliff calculator shows the room left under the line.

Fill the low brackets every year

With little earned income, the first $16,100 of ordinary income of a single filer is untaxed in 2026, and the next $12,400 of taxable income is taxed at 10 %. Converting that much from a traditional IRA to a Roth every year, or drawing it from a 401(k) under the rule of 55, moves money out of pre-tax accounts at almost no cost and builds the next rungs of a ladder. Long-term gains up to $49,450 of taxable income stay at 0 % (0 % gains calculator).

Check your state before you move

States treat early withdrawals very differently. California adds its own 2.5 % tax on early distributions on top of the federal 10 %. Illinois subtracts retirement plan and IRA payouts at any age; Iowa excludes them from the year you are 55; New York's $20,000 exclusion starts only at 59½; Georgia's at 62. Several states, Washington, Texas and Florida among them, have no individual income tax at all. The state comparison applies each rule as read on the state's revenue site.

Leave Social Security as a margin

The calculators leave Social Security out and treat any future benefit as a safety margin, not as income: if it turns out smaller, or you claim it later, the plan still holds.

Questions readers ask

How much do I need to retire at 45 in the US?

With $60,000 of yearly spending, the plain 4 % rule says $1,500,000. Add federal tax on withdrawals from a mostly pre-tax portfolio and twenty years of health premiums before Medicare and the figure rises to about $1,651,865 in 2026 dollars, before the question of which accounts you can reach before 59½.

Can I touch my 401(k) if I retire before 59½?

Yes, through an exception to the 10 % additional tax. Leaving the employer in or after the year you turn 55 opens that employer's 401(k); a 72(t) series opens any account at any age for fixed payments of at least five years; a governmental 457(b) owes no 10 % after you leave. Income tax is due in every case.

Does this FIRE calculator include taxes?

Yes. It applies the 2026 federal brackets, the $16,100 single standard deduction and the 0 % and 15 % rates on long-term gains from Rev. Proc. 2025-32 to the withdrawals of each year, and an optional flat state rate. It also adds the 10 % additional tax whenever the plan would need a penalized withdrawal.

Why is my retirement age later here than on other FIRE calculators?

Most calculators stop at 25 times spending and assume every dollar is reachable on the day you leave. This one adds tax, health premiums until Medicare at 65, and checks that each year before 59½ can be paid from money the rules let out without the 10 % penalty. Each of these can move the date by a year or more.

What is the safest way to bridge from early retirement to 59½?

There is no single answer; it depends on where the money sits. Taxable savings and Roth contributions are the most flexible. Leaving at 55 or later opens the last 401(k). Before that, a Roth ladder needs five years of other money, while a 72(t) series locks a fixed payment for at least five years and until 59½.

Do I need to pay for health insurance if I retire early?

Yes, until Medicare at 65. COBRA keeps the employer plan for up to 18 months at the full cost plus up to 2 %. A Marketplace plan may come with a premium tax credit based on your income; in 2026 the credit stops above 400 % of the federal poverty line, $62,600 for one person.
