The short answer

Your number must cover normal retirement spending plus the bridge from 55 to later milestones: age 59½ for common account rules, 62 for the earliest Social Security retirement benefit, and usually 65 for Medicare.

Build the bridge in three pieces

Start with the yearly gap between spending and dependable income. Divide that gap by a cautious withdrawal rate to get a rough long-term range. Then price the bridge years separately because they may be more expensive and use different accounts.

Health insurance is a major bridge cost. A person who loses job coverage before 65 may buy a Marketplace plan, and savings depend on household income. Retirement withdrawals can count as income, so the account you use can change the health-insurance price.

The federal Rule of 55 may remove the 10% additional early-distribution tax from a qualifying employer plan if you leave that employer during or after the calendar year you turn 55. It does not apply to an individual retirement account, and ordinary income tax can still apply.

One plan, two spending gaps

Chris expects to spend $84,000 a year and receive $18,000 of rent after costs. The gap before Social Security is $66,000. From 62 onward, an estimated $30,000 Social Security benefit could lower the gap to $36,000.

Instead of multiplying one forever number, Chris maps two periods: $66,000 a year from 55 through 61, then about $36,000 after Social Security starts, with a new health-cost estimate at 65. Chris also keeps qualifying money in the current employer plan until the Rule of 55 choice is clear.

Two choices that can change the bridge

Rolling a qualifying employer plan into an IRA before using the Rule of 55 can remove that particular exception. Check first; do not move the money by habit.

Starting Social Security at 62 reduces the monthly benefit compared with waiting. A bridge that delays claiming can be valuable, but it uses more savings early.

Three bridge questions

  1. What will health coverage cost from 55 to 65?
  2. Which accounts can fund each bridge year?
  3. How does the plan change if Social Security starts later?

Quick answers

Is $1 million enough to retire at 55?

The answer depends on the spending gap, other income, health coverage, taxes, and how long the money must last. Map the bridge years before judging the balance.

Can I withdraw from my 401(k) at 55 without the 10% additional tax?

Possibly, if you separate from that employer during or after the calendar year you turn 55 and the plan allows the withdrawal. The exception does not apply to IRAs.
