Early Retirement

Retiring early changes a plan in three ways at once: fewer years to save, fewer years of compounding, and more years of spending, often 35 or more if you stop in your 50s. The income that normally carries a retirement also arrives late, because Social Security, Medicare, penalty-free account access and many pensions key off ages in the late 50s and 60s.

People get there by two routes. Some plan it for years, building a portfolio large enough to replace their paycheck, the idea behind FIRE. Others are offered it through a buyout or a pension that allows an early start. Many land in between: semi-retirement steps down to part-time or project work for good, while a sabbatical or a mini-retirement tests the idea with a break you return from.

Either way, the plan has to answer one question: which money pays for each year between your last paycheck and the income that eventually takes over?

There is no penalty for retiring early as such. The costs come from reaching for income before the age it is designed for, and from the gaps between those ages, shown in the table below.

Account access comes first. Distributions from IRAs and workplace plans before 59½ generally owe a 10% additional tax on top of income tax, though the rule of 55 frees the plan of an employer you leave in or after the year you turn 55. Medicare generally starts at 65, and SSA advises signing up about 3 months before your 65th birthday even if you delay Social Security, because signing up late for Part B or Part D can mean a lasting premium penalty.

Social Security is the most flexible. Benefits can start at 62, but for anyone born in 1960 or later that pays 70% of the full amount for life, while waiting until 70 raises it to 124%. Early retirees who can fund the bridge often treat a later claim as insurance against outliving their savings.

The bridge is the stretch between your last paycheck and the income that replaces it. Its size is roughly your yearly spending, minus any income you still have, multiplied by the years until Social Security or a pension starts, as in the worked example below.

The order of accounts matters as much as the total. Before 59½, the usual sources are cash, a taxable brokerage account and Roth IRA contributions, which come back tax- and penalty-free. Traditional accounts can be reached through 72(t) substantially equal payments, which must run until the later of five years or 59½, or a Roth conversion ladder, where each conversion becomes penalty-free after its own five-year clock.

Taxes and health insurance interact. Low-income years are a chance to convert traditional savings to Roth at low rates, but the same income sets your premium tax credit for marketplace coverage, which for 2026 is available only between 100% and 400% of the federal poverty level.

Sometimes an employer puts early retirement on the table. Buyouts typically combine severance, subsidized health coverage for a time and sometimes extra pension credit, in exchange for leaving by a deadline and signing a release of legal claims.

Federal age-discrimination law gives workers 40 and older time to weigh them. A release of age claims signed in a group exit incentive program is valid only if you get at least 45 days to consider it and 7 days to revoke it after signing, are advised in writing to consult a lawyer, and are told who is eligible and the ages of those selected and not selected. An individual offer needs 21 days to consider.

Defined benefit pensions often have their own early-retirement rules, usually a permanent reduction for starting early. Under FERS, for example, a voluntary early retirement offer is open at 50 with 20 years of service or at any age with 25, while the MRA+10 option cuts the annuity by 5% for each year under 62 unless you postpone it to 62, or to 60 with 20 years of service. Weigh any pension lump sum against the annuity it replaces.

The case for retiring early is time: more healthy years for family, travel, caregiving or work you choose, and an exit from a job that is wearing you down. The costs go beyond the extra years of spending.

A longer retirement usually calls for a lower safe withdrawal rate, because the classic 4% research tested 30-year periods. It also stretches your exposure to sequence-of-returns risk, since a market slump in the first years of withdrawals does lasting damage.

Social Security takes a quieter hit. Your benefit is based on the average of your 35 highest years of indexed earnings, so each year you don’t work before you have 35 years on record puts a zero into that average. Because the benefit formula is progressive, the cut in the check is smaller than the cut in the average, but it lasts for life and carries into any survivor benefit.

None of this makes early retirement a mistake. It means the plan needs more margin: spending you could trim, a willingness to earn some income if markets turn, and a Social Security claim that protects your later decades.
