How to Retire at 55

Work from lifestyle to income to assets. List your real annual spending, including health insurance, taxes and irregular costs like cars and home repairs. Subtract the income that will arrive without selling investments: rental income, consulting or business income, an early pension, dividends and interest. The remainder is your gap, and your portfolio has to cover it for roughly 35 years.

The Rule of 55 is the main reason 55 is easier than 50. If you leave your job in or after the calendar year you turn 55, you can take withdrawals from that employer's 401(k) or 403(b) without the 10% early withdrawal penalty. It only covers the plan at the employer you just left, not old 401(k)s or IRAs, so rolling the account into an IRA before you use it gives up the benefit. Some plans only allow a single lump sum or limited withdrawals, and payments that go to you rather than to another retirement account carry 20% mandatory federal withholding, so check your plan's rules before you give notice. For IRAs, a 72(t) plan of substantially equal periodic payments is the other route, and it must run until 59½, which at 55 is about five years.

Paying off the mortgage still carries a lot of weight. Removing a $3,000 monthly payment cuts $36,000 a year from what your investments must cover, which at a 3% to 3.5% withdrawal rate is roughly $1M to $1.2M of assets you no longer need. It also keeps reported income lower, which helps with ACA subsidies until Medicare at 65.

Income sources are what let you leave the portfolio alone. A pension from your employer may be available at 55 with a reduction, or only later at full value, so compare both. Rental income works if you are willing to manage tenants or pay a manager. Part-time consulting or a small business can bridge the decade before Social Security. A large taxable brokerage account can supply both dividends and planned sales at low capital gains rates. Social Security cannot start until 62, and claiming then cuts the benefit by 30% for life, so most early retirees plan to bridge to a later claim.

Withdrawal rates should start conservative and rise with age. As a planning range, Singh PWM uses about 3% to 3.5% in the mid to late 50s, about 3.5% to 4% in the 60s and 4.5% to 5% or more in the 70s. The longer the remaining horizon, the lower the rate. These are illustrative, assume you can cut spending in a bad year, and work best when other income covers most of the lifestyle.

Take a couple who want $130,000 a year at 55, with the home paid off. Consulting brings in $25,000 and net rental income $20,000, leaving an $85,000 gap. At 3% to 3.5%, that needs about $2.4M to $2.8M of investments. Add a $3,000 mortgage payment and the gap becomes $121,000, which needs about $3.5M to $4M. Add a $30,000 early pension instead and the gap falls to $55,000, needing about $1.6M to $1.8M. Debt and income move the target more than market returns do.

The ideal for the mid to late 50s is that income handles day-to-day life and the portfolio is only tapped for planned withdrawals or one-off costs. If your investments are large relative to spending, a 3% to 3.5% draw can carry more of the load, but every dollar of other income lets the portfolio keep growing toward the years when Social Security and Medicare arrive.

Plan the tax and health insurance side together. Withdrawals from the 401(k) using the Rule of 55 are ordinary income. Drawing too much in one year can push you over the ACA subsidy cliff (about $84,600 of income for a two-person household for 2026 coverage). Mixing in taxable account sales, cash and Roth contributions keeps reported income in a range you choose, and the low-income years before Social Security can also be used for Roth conversions.

• Rolling the current 401(k) into an IRA right after leaving work, which gives up the Rule of 55 and forces a 72(t) plan or penalties.
• Leaving the job in the year before you turn 55, which does not qualify for the Rule of 55 even if you turn 55 later.
• Not checking whether the plan allows partial withdrawals, then being forced into a lump sum and a large tax bill.
• Claiming Social Security at 62 to cover the bridge, locking in a 30% permanent reduction.
• Drawing 4% or more in the mid 50s from a portfolio that has to last 35 years.
• Taking large IRA or 401(k) withdrawals that push income over the ACA subsidy cliff.
