How to Plan for Retirement in Your 20s

20 多岁如何规划退休

Retirement planning in your 20s feels theoretical. The word "retirement" conjures a vague future you cannot visualize, and the dollar amounts involved look enormous — six or seven figures, in some distant decade. So most people do nothing, assuming they will "get serious about it later." Later arrives at 35 or 40, and the math reveals the cost of waiting. This guide is a clear, concrete starter pack: why your 20s are uniquely powerful, the four numbers you need to know, examples at three income levels, and the small set of decisions that compound for decades. None of this requires financial sophistication. It requires showing up, putting a number in a spreadsheet, and then letting time do the heavy lifting.

在 20 多岁规划退休，听起来像在讨论一件很抽象的事。"退休"这个字唤起的是一个你无法想象的遥远未来，涉及的金额看起来大得吓人 —— 六位数、七位数的数字，发生在很多年后。于是多数人什么都不做，想着"以后再认真对待"。可"以后"真正到来时，往往是 35 或 40 岁，账本上的差距已经把代价写得清清楚楚。这份指南就是一份直接、可落地的入门包：为什么 20 多岁是独一无二的黄金期、四个关键数字怎么算、三档收入下的具体例子，以及那几件会复利几十年的小决策。整套方法不需要多深的金融知识，只需要打开表格写下几个数字，然后让时间替你干活。

Why your 20s are the highest-leverage decade

为什么 20 多岁是杠杆最大的十年

Leverage, in finance, means small actions today producing outsized results later. In your 20s, every dollar you invest has 35–45 years to grow. At a 7% real (inflation-adjusted) return, a dollar invested at 25 becomes about $14 at 65. A dollar invested at 35 becomes about $7.5. A dollar invested at 45 becomes about $4. Each decade you wait roughly halves the long-term value of the same contribution. The person who starts at 25 with $100/month will end up with more retirement wealth than the person who starts at 35 with $200/month — and at 45 with $400/month — even though they contribute the same total dollars. Time, not size, is the dominant factor in your 20s.

杠杆在金融里的意思是：今天一个很小的动作，未来会产生不成比例的结果。在 20 多岁，你投的每一美元都有 35–45 年的增长时间。按 7% 的实际（扣除通胀）回报率算，25 岁投入的 1 美元，到 65 岁大约值 14 美元；35 岁投入的 1 美元，到 65 岁大约值 7.5 美元；45 岁投入的 1 美元，到 65 岁大约值 4 美元。每晚 10 年，长期价值差不多砍半。一个 25 岁开始每月投 100 美元的人，最终会比一个 35 岁开始投 200 美元、45 岁开始投 400 美元的人，拥有更多的退休资产 —— 即使他们累计投入的本金相同。在 20 多岁，决定结果的主导力量是时间，而不是金额。

There is a second reason your 20s are special: lifestyle obligations are at their lowest. You are unlikely to be supporting children, paying a large mortgage, or caring for aging parents yet. Income is modest, but so are fixed costs. This window of low fixed cost + long horizon is the cheapest chance you will ever have to build a base. Skipping it because "I don't earn enough" is a common mistake — you don't need to invest a lot, you need to invest a little, consistently, for a long time.

20 多岁还有一个特殊之处：生活负担处于一生最低点。你大概率不用养孩子、没有大额房贷、也还没开始照顾年迈的父母。收入虽不高，但固定支出也低。这个"低固定支出 + 长时间窗口"是你一生中成本最低的起步机会。"我现在挣得少"而推迟起步是个常见错误 —— 你不需要投很多，而是要投一点、坚持投、长期投。

The four numbers that drive the result

决定结果的四个数字

Most retirement projections in the world reduce to four variables:

几乎所有的退休测算，本质上都可以归到四个变量：

Current income — your gross annual salary today, used to size contributions as a percentage rather than a fixed dollar amount.
当前收入 — 你今天的年税前收入，用来把"投入金额"换算成"投入比例"。
Savings rate — what percentage of income you invest for retirement. Going from 5% to 10% is one of the highest-leverage financial decisions a young person can make.
储蓄率 — 你把收入的百分之多少投入退休账户。从 5% 提到 10%，是年轻人能做的杠杆最大的财务决策之一。
Expected real return — your annualized return after inflation. A reasonable long-term assumption for a diversified global stock portfolio is 4–6% real.
预期实际回报 — 扣除通胀后的年化回报。对一个分散配置的全球股票组合，长期合理假设是 4%–6% 实际回报。
Target — the multiple of your final income you want as retirement assets. A common rule of thumb is 25× annual expenses (the "4% safe withdrawal rate").
目标 — 你希望退休时拥有的资产相当于你退休前几年支出的多少倍。一个常用经验是年度支出的 25 倍（"4% 安全提取率"）。

These four numbers are enough to back-solve a savings rate. Most online retirement calculators — including simple spreadsheets — work fine once you commit to values for each. The discipline is choosing numbers you can defend, not numbers that make the chart look beautiful.

有了这四个数字，你就可以反推出需要的储蓄率。大多数在线退休计算器，包括简单的电子表格，在这四个值确定后都能跑出可信结果。关键不是让曲线漂亮，而是每个数字都能被你说清楚来源。

Worked examples at $40k, $60k, and $100k

4 万、6 万、10 万美元收入下的具体例子

Suppose each person starts at age 25, targets 25× final income as the retirement goal, and assumes 5% real annual return. A 25-year-old earning $40,000 today, expecting raises, needs to invest roughly 10% of income each year (including any employer match) to retire around age 60–62. A peer earning $60,000 needs about 10–12%, because the absolute dollars saved are larger but the goal is also larger. A peer earning $100,000 needs about 12–15% to reach 25× final income, since lifestyle inflation often pushes expenses up with income. These percentages are not set in stone; they depend on the assumed real return, the target multiple, and years to retirement. The point is to plug your numbers into a calculator and see the rate that closes the gap.

假设三个人都从 25 岁开始，目标资产为退休前收入的 25 倍，假设实际年化回报 5%。今天挣 4 万美元的人，每年需要把大约 10% 的收入投入退休账户（含雇主匹配），才能在 60–62 岁附近退休。挣 6 万美元的人大约需要 10%–12%，因为绝对金额更大，目标金额也更大。挣 10 万美元的人大约需要 12%–15% 才能达到 25 倍目标，因为"生活方式通胀"通常让支出跟着收入水涨船高。这些百分比不是定数，取决于实际回报、目标倍数、距离退休的年数。重点是把你的真实数字输入计算器，看哪个比例刚好能填平缺口。

A 10% savings rate is achievable for most 20-somethings if expenses are kept in check. The trick is to increase the rate with each raise, not just with each year. When your salary goes from $50,000 to $54,000, route at least half of the raise to retirement. Lifestyle inflation is the silent killer of retirement plans; savings-rate inflation is the cure.

对大多数 20 多岁的人来说，10% 的储蓄率是可达成的，前提是支出不失控。诀窍是"每次加薪就同步加储蓄率"，而不是"熬一年再调一次"。当你的薪水从 5 万涨到 5.4 万时，至少把加薪幅度的一半拨到退休账户。生活方式通胀是退休计划最沉默的杀手，对应的解药就是"储蓄率通胀"。

Employer match: free money you should never leave

雇主匹配：永远别错过的"免费钱"

If your employer offers any retirement match, contributing enough to get the full match is the single highest-return action available to you. A 50% match up to 6% of salary is an instant 50% return on your first 6%; a 100% match up to 4% is a 100% return on the first 4%. There is no investment strategy in existence that consistently delivers 50% or 100% in a year. Skipping the match because "I will start saving next year" is, in financial terms, lighting a 50-dollar bill on fire and putting the ashes in a savings account. Do this first, before anything else.

如果你的雇主提供任何退休匹配，缴够金额以拿到全额匹配是你能做的、回报最高的动作。对前 6% 工资的 50% 匹配，相当于立刻拿到 50% 的回报；对前 4% 工资的 100% 匹配，等于 100% 的回报。世界上不存在能稳定做到一年 50% 或 100% 的投资策略。因为"明年再开始"而错过匹配，在金融上等于把一张 50 美元钞票点燃烧掉，再把灰存进储蓄账户。这件事永远排在第一优先级。

Once the match is captured, you are still likely under-saving. The match is the floor, not the ceiling. Many people cap contributions at the match because the next dollar "feels" more expensive — the same money could go to a nicer phone or a weekend trip. The truth is that the next dollar saved is also the most powerful one, because it is invested at age 27 instead of age 47.

拿到匹配之后，你的储蓄率很可能仍然偏低。匹配是地板，不是天花板。不少人把投入金额卡在匹配上限，因为"多投的那一块"感觉更贵 —— 同样一笔钱可以换个新手机或者去度个周末。真相是，存下来的下一块钱也是力量最大的一块钱，因为它是在 27 岁而不是 47 岁投进去的。

Roth vs traditional: which account type to choose

Roth 还是传统账户：怎么选

In a traditional account, you contribute pre-tax dollars, the money grows tax-deferred, and you pay income tax on withdrawals in retirement. In a Roth account, you contribute post-tax dollars, the money grows tax-free, and qualified withdrawals are tax-free. The "right" answer depends on your marginal tax rate today versus your expected tax rate in retirement. A simple heuristic for 20-somethings: lean heavily toward Roth. Your current tax rate is likely low (early career), and you have decades of tax-free growth ahead. As income rises, traditional accounts become more attractive. Many people end up using both.

在传统账户里，你用税前收入存入，资金增值时递延纳税，退休提取时按个人所得税缴纳。在 Roth 账户里，你用税后收入存入，资金增值免税，符合条件的提取也免税。哪个更划算，取决于"你今天的边际税率"和"你退休时预期的税率"。对 20 多岁的人来说，一个简单的经验是：优先选 Roth。你当前的税率通常较低（事业刚起步），且有数十年免税增长的窗口。随着收入上升，传统账户的优势会逐渐显现。很多人最终会两种账户都用。

There is also a behavioral benefit to Roth: you have already paid the tax, so future tax-rate changes cannot harm you. You will not wake up at 60 to find that your retirement assets are now subject to a higher bracket than the one you planned for. The certainty of tax-free income is itself valuable.

Roth 在行为上还有一个好处：你已经交过税，未来税率怎么变都不会影响你。你不会在 60 岁时发现，自己退休资产所适用的税率比当年假设的要高。免税收入本身的"确定性"就很有价值。

Pay yourself first

先付钱给自己

"Pay yourself first" means routing savings to your retirement account on the same day your paycheck arrives, before you allocate anything to discretionary spending. Done manually, this requires willpower every pay period; done automatically, it requires a single 10-minute setup. The 20-year-old who automates 10% of every paycheck into a low-cost index fund and never touches the account will, in most historical scenarios, end up wealthier than the 30-year-old who tries to "save what's left" each month. There is rarely anything left.

"先付钱给自己"指的是：发薪当天就把储蓄拨进退休账户，再把剩下的钱用于消费。手动执行时，需要每个发薪周期都动用一次意志力；自动化执行时，只需要 10 分钟做一次设置。一个 20 多岁的人，只要把每笔薪水的 10% 自动转入一只低成本指数基金，从此不再碰它 —— 在大多数历史情境下，最终都会比一个 30 岁、每月试图"剩多少就存多少"的人更富有。剩多少，往往就是零。

A common objection is, "But I want to enjoy my 20s." That is a fair point. The compromise: keep your savings rate modest enough to leave room for genuine life enjoyment, but commit to automating it so the decision is already made. Travel, hobbies, dinners with friends — these are worth having. Letting your future self become a stranger who never saved — that is not.

一个常见的反对意见是："但我想享受 20 多岁。"这个想法没问题。折中方案是：把储蓄率设在一个让你仍有真实生活余地的水平，但一定要自动化，让决策在你手上完成一次就好。旅行、爱好、和朋友吃饭 —— 这些值得拥有。让未来的自己变成一个"从来没存过钱"的陌生人 —— 这个结果不值。

What to skip — and what not to skip — in your 20s

20 多岁可以先放一放、一定别放的事

It is okay to skip in your 20s: buying a house, a luxury car, a wedding that costs more than you can pay in cash, individual stock picking, crypto speculation, and expensive "investing" courses. It is not okay to skip: emergency fund basics, paying off any high-interest debt (especially credit card balances), basic insurance coverage, and contributing at least enough to capture the full employer match. This short list separates the people who enter their 30s with optionality from those who enter their 30s stuck.

20 多岁可以先放一放的事：买房、买豪车、超出付现能力的婚礼、个股投机、加密货币投机、昂贵的"投资课"。一定不能跳过的事：基本的应急资金、还清所有高息债务（尤其是信用卡）、基础的保险配置，以及至少缴够拿到全额雇主匹配的金额。这张短清单，决定了一个人走进 30 多岁时手里是"选择权"还是"困局"。

The most underrated item is the emergency fund. Without one, the first unexpected expense — a car repair, a medical bill, a job gap — will either wipe out your retirement progress (via early withdrawal and penalties) or land you in credit card debt that compounds against you. A modest emergency fund of one to two months of essential expenses is enough to defend your long-term plan.

最被低估的一项是应急资金。没有它，第一笔意外支出 —— 修车、医疗账单、失业空窗 —— 就会以两种方式毁掉你的退休进度：要么提前支取加罚款，要么背上一笔反向复利（利滚利）的信用卡债。一个金额不大、覆盖 1–2 个月刚性支出的应急资金，就足以守护你的长期计划。
