How to figure out how much you need to retire early

Wanting to retire early is easy to talk about. Knowing whether you can afford it requires a less romantic number: once your paycheck stops, what does a year of your life cost, and where does that money come from? Get the annual figure right and the savings target stops being abstract.

Start with the life you plan to fund

Begin with last year's actual bills. Daily spending comes first, then the big items that visit every few years rather than every month. After that, adjust for what's ahead: housing, children, elder care, each of these arrives on a different schedule and runs for a different length of time. If a pension or some years of continued work are on the table, place them where they actually start and stop, not where you'd like them to.

Say a family needs 80,000 yuan a year and expects every cent to come from investments. At a 4% withdrawal rate, the required nest egg is 2,000,000 yuan. At 3%, about 2,670,000. At 5%, 1,600,000. These are starting estimates based on different assumed withdrawal rates. Before choosing one, ask the harder questions: how many years must this cover, what do you actually own, and how much could your spending bend in a bad year?

Two bookkeeping notes. If you'll keep living in your house with no plans to sell it, list it under housing arrangements rather than counting it as money to live on. And when you list what's available to spend, use money you can actually reach. Backup cash already sitting inside the portfolio counts once, not twice.

Taking 80,000 a year and taking 4% a year are two different lives

Here is the difference, concretely.

Option one: a fixed amount that grows with prices. You take 80,000 in year one. If costs rise 3%, you take 82,400 the next year. The withdrawal is designed to preserve purchasing power, while the investment balance absorbs market changes.

Option two: a percentage of whatever remains. If the account slides from 2,000,000 to 1,500,000, your 4% gives you 60,000 instead of 80,000. Whether that works comes down to a plain question: can this family actually live on less?

The honest way to answer is to sort spending into what's essential and what's movable, then write down the specific choices. "I'll cut back if needed" becomes "the holiday happens next summer instead of this one," "the car stays as it is," "the subscription goes." Each one has a size and a duration. A vague promise doesn't.

Why good average returns can still leave you short

Here's a two-year example that exists only to explain the mechanism. Two people each start with 1,000,000 and take out 100,000 at the end of each year.

Person A enjoys the market first: it rises 20%, then falls 20%. Their balance goes from 1,100,000 to 780,000. Person B suffers the same moves in reverse: down 20%, then up 20%. Their balance goes from 700,000 to 740,000. Taxes and inflation are ignored on purpose; what's on display is order.

Neither investor took a hit the other didn't. Same average return, same total withdrawals, and yet one ends 40,000 richer. Why? Because withdrawing changes the base that later moves apply to. Person B sold into the downturn to pay the bills, so the rebound multiplied a smaller balance. Had neither withdrawn anything, both would have finished at 960,000.

The takeaway for a retirement plan: the market path in your first years out matters enough to test on its own.

Include dividends you spend in withdrawals

Suppose a 2,000,000 portfolio pays dividends equal to 1.2% of its opening balance, and you spend them. You also sell enough holdings worth another 3% of the opening balance to cover life. The year's total outflow is 84,000, which is 4.2% of the opening assets, not the 3% you'd report if you only watched the sales.

The rule is to book money by where it actually goes. Dividends reinvested keep compounding inside the portfolio and never touch your budget. Dividends spent are a withdrawal, the same as selling shares. And when you read a total return that already includes dividends, don't count those dividends a second time.

Keep the plan as a ledger you update

Lay out each future year: what you'll spend, what other income arrives, and the gap that must come from savings. Assign the money you can actually use, then run a few different return and price paths through it. Pay special attention to early downturns and ask whether the spending cuts you promised are ones you could genuinely make. If you're retiring in your twenties, the years to cover are whatever your own timeline says, not someone else's retirement at 65.

Once a year, check the ledger against reality: actual spending, actual balance. That habit beats clinging forever to the one number you calculated back when everything was hypothetical.

Notice how the levers connect. Trimming a fixed expense raises this year's savings and lowers every future withdrawal. Adding a job with an end date shrinks the gap for as long as that job lasts.

The formulas and withdrawal methods live in retirement spending and asset withdrawals; the purchasing-power math is in compounding, fees, and purchasing power. Still building rather than spending down? Follow up with turning investment returns into personal gains.
