Early retirement calculator
Savings grow until you stop work; then withdrawals cover spending, minus Social Security once it starts.

Uses a steady 3.41% real return (6% minus 2.5% inflation). Real markets vary: a bad first decade can sink a plan that works on averages. Before 59½, withdrawals from 401(k)s and IRAs can carry a 10% penalty unless an exception applies (such as separation from service at 55 or later, or equal periodic payments).

How the early retirement calculator works
The early retirement calculator works in today's dollars with a real return: your return minus inflation, (1 + 6%) ÷ (1 + 2.5%) − 1 = 3.41% with the defaults. It then runs your plan in two phases:
- Saving. Your balance grows at the real return and you add your yearly savings until the retirement age.
- Spending. Each year you withdraw your spending minus Social Security (zero Social Security until your claiming age). If the balance goes below zero before your plan age, the result shows when.
"Needed at retirement" is the present value of every year's shortfall: the lump sum that, earning the real return, pays the gap exactly to your plan age. Early retirees face a long gap: from 55 to 67 the full $60,000 a year comes out of savings, $720,000 before any Social Security arrives.
How much you need to retire early
The earlier you stop, the larger the nest egg, because the savings must cover more years and all of them before Social Security. With $2,200 a month from 67, a 3.41% real return and a plan to 95:
| Spending a year | Retire at 50 | Retire at 55 | Retire at 60 | Retire at 65 |
|---|---|---|---|---|
| $40,000 | $668,722 | $569,517 | $452,178 | $313,390 |
| $60,000 | $1,140,753 | $1,017,111 | $870,868 | $697,893 |
| $80,000 | $1,612,784 | $1,464,705 | $1,289,559 | $1,082,396 |
| $100,000 | $2,084,815 | $1,912,299 | $1,708,249 | $1,466,898 |
Social Security is worth a lot in this math: $2,200 a month for 28 years from 67 covers $739,200 of spending. Retiring early can also lower that benefit, because the years you no longer work count as zeros in your 35-year average; run your numbers in the Social Security calculator and see the claiming ages on the full retirement age page[nra].
Worked example: retire at 55
A 40-year-old with $400,000 who saves $30,000 a year reaches about $1,237,133 (today's dollars) at 55. They plan to spend $60,000 a year and claim $2,200 a month at 67. The first-year withdrawal is 4.8% of savings, the gap needs $1,017,111, and at the steady assumed return the plan lasts past 95. The same plan with spending of $80,000 needs $1,464,705, more than they will have.
Getting at retirement money before 59½
Withdrawals from 401(k)s, IRAs and similar plans before age 59½ carry an additional 10% tax unless an exception applies[exc][p590b]. Exceptions that matter for early retirees include:
- Separation from service at 55 or later (50 for public safety employees in governmental plans): withdrawals from that employer's plan only, not from IRAs[exc].
- Substantially equal periodic payments (section 72(t)): a fixed schedule from a plan or IRA that must continue until the later of five years after the first payment or age 59½; changing it early brings back the 10% tax on past payments, with interest[sepp].
- Roth IRA contributions can be withdrawn at any time without tax; earnings follow the Roth rules (see the Roth IRA calculator).
- Taxable brokerage accounts have no age rules; many early retirees spend these first.
Common mistakes
- Planning on averages. A steady return hides sequence risk: a market fall in the first years of withdrawals does more damage than the same fall later. Test a lower return.
- Forgetting health insurance. Coverage before Medicare at 65 is a large, separate cost; include it in spending.
- Leaving out taxes. Spending here is before tax; withdrawals from pre-tax accounts are taxable income.
- Using a 30-year rule for a 45-year retirement. The longer the money must last, the lower the withdrawal rate it can support; set the plan age high enough.

Frequently asked questions
How much do I need to retire early?
Roughly the present value of your spending until your plan age minus what Social Security covers. Spending $60,000 a year from 55 with $2,200 a month of Social Security from 67 needs about $1,017,111 at a 3.41% real return; retiring at 50 needs $1,140,753.
Can I retire at 55 with $1 million?
At $40,000 a year with $2,200 a month of Social Security from 67, the calculator's need is $569,517, so yes on these assumptions; at $60,000 a year the need is $1,017,111. Lower returns, higher spending or health costs change the answer.
Can I withdraw from my 401(k) at 55 without penalty?
Yes, from the plan of the employer you leave in or after the year you turn 55 (50 for some public safety workers). The exception does not apply to IRAs or to plans of earlier employers.
Does retiring early reduce Social Security?
It can. Your benefit averages your highest 35 years of indexed earnings, so stopping work early adds zero years if you have fewer than 35. Claiming before full retirement age reduces it further.
