When can I retire? Years to independence, then the 59½ test
Type what you have, what you add each year and what you plan to spend: the calculator counts the years until your savings cover that spending, then flags how many of those years fall before 59½.
You can retire at about
age 55
19.8 years to reach $1,500,000.
| Target (spending ÷ rate) | $1,500,000 |
| Saving $10,000 more a year | 17.1 years |
| Spending $10,000 less | 17.2 years |
| Before 59½: plan the bridge | 4.7 years to cover |

A saver of 33 with $150,000 invested, who adds $36,000 a year and wants $55,000 of yearly spending, needs $1,375,000 under a 4 % withdrawal rate and gets there in 18 years, around age 52, with a 5 % return after inflation. Saving $10,000 more a year cuts the wait to 15.6 years; spending $10,000 less, with the same savings, cuts it to 15.4, because the target itself shrinks by $250,000. Doing both brings it to 13.3 years. The date the arithmetic gives is not yet a date you can stop working: about 8.5 years would sit before 59½, when most 401(k) and IRA money still owes the 10 % additional tax. Run through the full plan, with federal tax, health premiums until Medicare and the access rules, the same person moves from age 52 to age 54.
The count the calculator makes
The answer to "when can I retire" is a race between two numbers. One is the target: yearly spending divided by the withdrawal rate you accept, $1,375,000 for $55,000 at 4 %. The other is your balance, which grows each year by the return and by what you add. The calculator advances year by year, adds the contribution at the end of each year and stops at the first year the balance crosses the target, with a fraction for the part of the last year needed. Everything is in today's dollars, which is why the return field asks for a figure after inflation.
For the case above, the crossing comes after 18 years. That is the honest headline, and also the place where most online tools stop. The remainder of this page covers what moves that figure and what it leaves out.

Ten thousand dollars on either side of the budget
A cut in spending works twice. It lowers the target by $250,000 at a 4 % rate, and in real life the same dollars usually end up invested. The calculator lets you test the two levers apart: the table below keeps the starting balance and the return fixed and varies only the yearly contribution, once for the original budget and once for a budget $10,000 lower.
| Saved per year | Years to $1,375,000 | Years to $1,125,000 |
|---|---|---|
| $26,000 | 21.3 | 18.4 |
| $36,000 | 18 | 15.4 |
| $46,000 | 15.6 | 13.3 |
| $56,000 | 13.8 | 11.7 |
The gain per extra dollar shrinks as contributions climb: going from $26,000 to $36,000 a year saves more time than going from $46,000 to $56,000. Early on, the contribution is most of the growth; later, the return on the balance already built does most of the work, and new money matters less.
The withdrawal rate sets the finish line
The target is spending divided by a rate, so the rate you accept matters as much as anything you save. At 3.5 % instead of 4 %, the same $55,000 budget needs $1,571,429, and the wait grows from 18 to 19.8 years. Someone retiring in the early fifties may need the money for forty years or more, longer than the thirty-year periods behind the classic 4 % figure, which is why many early retirees test a lower rate. The 4 % rule page shows how long a portfolio lasts at each rate.
How much the return assumption decides
The return is the field people leave at its default and should not. Over a twenty-year horizon, one point of real return moves the date by years. The figures below change only that input.
| Real return per year | Years to the target | Age reached |
|---|---|---|
| 3 % | 21.8 | about 55 |
| 4 % | 19.7 | about 53 |
| 5 % | 18 | about 52 |
| 6 % | 16.6 | about 50 |
| 7 % | 15.4 | about 49 |
No one can promise any line of that table. A prudent reading is to plan on a low line and treat a higher one as a margin. Also note that a market fall shortly before or after the date you pick hurts more than the same fall twenty years earlier, a point the sequence of returns page measures.
The wall at 59½
Reaching the target at 52 means nothing if the money is in the wrong accounts. The tax code adds a 10 % additional tax to most withdrawals from a 401(k) or IRA before age 59½, with a list of exceptions (IRS table of exceptions). Retiring at the date above leaves about 8.5 years to fund from money you can reach: a taxable brokerage account, Roth IRA contributions, a governmental 457(b), the 401(k) of the employer you leave if that happens in or after the year you turn 55, or a 72(t) series.
The full early retirement calculator applies those rules to the same person. Suppose the $150,000 is split as $20,000 in a brokerage account, $100,000 in a 401(k) and $30,000 in a Roth IRA, of which $25,000 are contributions, and that the $36,000 goes $24,500 to the 401(k), $7,500 to the Roth and the rest to the brokerage account. Add federal tax on withdrawals and $7,200 a year of health premiums until 65. The plain rule says age 52. The plan that funds every year without a penalty says age 54.
Stopping at 52 anyway does not ruin anything, it just costs money. The year-by-year run shows the reachable accounts running dry at 57, after which the 401(k) pays the bills with $18,596 of 10 % additional tax in total before 59½. That is the price of retiring on the plain number with most savings in pre-tax accounts.

One change in where the savings go
The same saver can move $10,000 a year from the 401(k) to the brokerage account, keeping the total at $36,000. The engine then finds age 52 instead of 54: more money sits outside the 59½ lock, and the target with tax is lower because fewer withdrawals are ordinary income. The trade-off is a higher tax bill during the working years, since a brokerage contribution gets no deduction. Whether that trade is worth it depends on your bracket now and later, which is why the calculator lets you test it instead of answering for you.
Social Security is left out of every figure here. For the order in which each account opens, see when each account can be drawn; for the target itself with tax and health premiums, the FIRE number calculator.
