Common Financial Planning Models and Income Allocation Strategies
常見理財模式與收入分配策略
A roundup of common financial planning patterns to help you allocate your income and resources more effectively based on your goals — whether that's a target retirement age, a savings milestone, or something else entirely.
整理各種常見的理財 pattern，幫助我們依照目標（退休時間、儲蓄金額等），更好地分配收入與資源。
1. Classic Budget Allocation Rules
1. 經典預算分配法則
The 50/30/20 Rule (Needs / Wants / Savings)
50/30/20 法則（需要 / 想要 / 儲蓄）
Popularized by U.S. Senator Elizabeth Warren in her book All Your Worth, this rule is based on after-tax income:
由美國參議員 Elizabeth Warren 在《All Your Worth》一書中推廣，以稅後收入為基準：
- 50% Needs: Rent/mortgage, groceries, transportation, utilities, insurance, minimum debt payments
- 30% Wants: Dining out, entertainment, travel, shopping, subscriptions
- 20% Savings & Debt Repayment: Emergency fund, retirement investments, extra debt payoff
- 50% 需要 (Needs)：房租/房貸、食物、交通、水電、保險、最低還款額
- 30% 想要 (Wants)：外食、娛樂、旅行、購物、訂閱服務
- 20% 儲蓄與還債 (Savings)：緊急備用金、退休投資、額外還債
Modern adaptations: In high-cost-of-living areas, capping "Needs" at 50% can be unrealistic. Common variations include:
- 60/30/10: For high-cost-of-living areas
- 60/20/20: For people with high fixed expenses
- 40/20/40: For aggressive FIRE pursuers
現代調整版本： 在高房價地區，50% 的「需要」上限可能不切實際，常見變體：
- 60/30/10：高生活成本地區
- 60/20/20：固定支出偏高的人
- 40/20/40：積極追求 FIRE 的人
The 70/20/10 Rule
70/20/10 法則
- 70% Living Expenses: All bills and daily spending (no need to separate needs from wants)
- 20% Savings & Investments: Retirement accounts, emergency fund, investment portfolio
- 10% Debt & Giving: Extra debt payoff, charitable donations
- 70% 生活支出：所有帳單與日常開銷（不區分需要與想要）
- 20% 儲蓄與投資：退休帳戶、緊急備用金、投資組合
- 10% 還債與捐獻：額外還債、慈善捐款
Works well in high-cost areas, but the downside is lumping necessities and luxuries into the same bucket.
適合高成本地區，缺點是把必需品和奢侈品混在同一桶。
The 80/20 Rule (Pay Yourself First)
80/20 法則（先付自己）
- 20% Savings: Automatically transferred the moment your paycheck hits
- 80% Everything Else: Spend the rest however you want — no detailed tracking needed
- 20% 儲蓄：收入一進來就自動轉入
- 80% 其他：剩餘的自由花用，不需要細分追蹤
The simplest approach — sometimes called the "anti-budget." Perfect for people who hate tracking expenses.
最簡單的方法——有時被稱為「反預算」。適合討厭記帳的人。
Other Methods

2. Goal-Oriented Financial Planning & the FIRE Movement
2. 目標導向財務規劃與 FIRE 運動
Calculate Your FI Number (Financial Independence Number)
計算你的 FI Number（財務自由數字）
Core formula: Annual Expenses x 25 = FI Number
核心公式： 年支出 x 25 = FI Number
This is based on the 4% Rule (Trinity Study, 1998): withdrawing 4% annually from your portfolio (adjusted for inflation) gives you a 95-99% probability of not running out of money over 30 years.
基於 4% 法則（Trinity Study, 1998）：退休後每年從投資組合中提領 4%（依通膨調整），有 95-99% 的機率在 30 年內不會把錢花光。
| Annual Expenses | FI Number (25x) | Conservative (33x, 3% withdrawal rate) |
|---|---|---|
| $30,000 | $750,000 | $990,000 |
| $50,000 | $1,250,000 | $1,650,000 |
| $80,000 | $2,000,000 | $2,640,000 |
| $100,000 | $2,500,000 | $3,300,000 |
| 年支出 | FI Number (25x) | 保守版 (33x, 3% 提領率) |
|---|
| $30,000 | $750,000 | $990,000 | | $50,000 | $1,250,000 | $1,650,000 | | $80,000 | $2,000,000 | $2,640,000 | | $100,000 | $2,500,000 | $3,300,000 |
If you plan to retire very early (before 45, facing 40-50+ years of retirement), a more conservative 3-3.5% withdrawal rate (annual expenses x 28.5-33) is recommended.
如果打算非常早退休（45 歲以下，面對 40-50+ 年退休生活），建議用更保守的 3-3.5% 提領率（年支出 x 28.5-33）。
Reverse-Engineering Your Savings Rate from a Target Retirement Age
從退休年齡反推儲蓄率
| Target Retirement Age | Years of Saving (from age 25) | Required Savings Rate | Expense Multiple |
|---|---|---|---|
| 65 (traditional) | ~40 years | 15% | 25x |
| 55 (early) | ~30 years | 25-35% | 25-28x |
| 45 (FIRE) | ~20 years | 50-75% | 28-33x |
| 目標退休年齡 | 存錢年數（從 25 歲起） | 所需儲蓄率 | 年支出倍數 |
|---|---|---|---|
| 65 歲（傳統） | ~40 年 | 15% | 25x |
| 55 歲（提早） | ~30 年 | 25-35% | 25-28x |
| 45 歲（FIRE） | ~20 年 | 50-75% | 28-33x |

FIRE 運動的各種類型
FIRE (Financial Independence, Retire Early) practitioners typically save 50-75% of their income.
FIRE (Financial Independence, Retire Early) 追求者通常儲蓄 50-75% 的收入。
| FIRE Type | Annual Expenses | FI Number | Lifestyle | Description |
|---|---|---|---|---|
| Lean FIRE | < $40,000 | < $1M | Minimalist | Ultra-frugal, bare-bones living |
| Regular FIRE | $50K-$100K | $1.25-2.5M | Comfortable | Maintain your current standard of living |
| Fat FIRE | > $100,000 | > $2.5-3M+ | Premium | No compromises on quality of life |
| Coast FIRE | Varies | Varies | Front-loaded | Save aggressively early on, then let compound growth do the rest — no more contributions needed |
| Barista FIRE | Varies | Partial | Semi-retired | Cover most expenses through investments, supplement with part-time work (and snag employer health insurance) |
| FIRE 類型 | 年支出 | FI Number | 生活風格 | 說明 |
|---|---|---|---|---|
| Lean FIRE | < $40,000 | < $100 萬 | 極簡 | 超級節儉，極低生活開銷 |
| Regular FIRE | $50K-$100K | $125-250 萬 | 舒適 | 維持目前的生活水平 |
| Fat FIRE | > $100,000 | > $250-300 萬+ | 豪華 | 不妥協生活品質 |
| Coast FIRE | 不定 | 不定 | 前期衝刺 | 年輕時存夠，之後靠複利成長，不再額外存入 |
| Barista FIRE | 不定 | 部分 | 半退休 | 大部分支出靠投資，再加上兼職工作（還能拿雇主健保） |

Strategy by Life Stage
各階段策略
20s — The Growth Phase:
20s — 成長期：
- Your greatest asset is time — compound growth is most powerful at this stage
- High risk tolerance: allocate 80-90% to equities
- Priorities: max out employer match, open a Roth IRA, build an emergency fund
- Even small amounts matter — the point is to start
- 最大優勢是時間，複利的力量在這個階段最強
- 風險承受度高：可配置 80-90% 股票
- 優先事項：拿滿雇主 match、開始 Roth IRA、建立緊急備用金
- 即使金額小也沒關係，重點是開始
30s-40s — The Balancing Act:
30-40s — 平衡期：
- Juggling multiple financial responsibilities: mortgage, student loans, kids
- Entering your peak earning years
- Increase your savings rate by 1-2% annually
- Gradually shift allocation to 70-80% equities, 20-30% bonds
- Start putting concrete retirement goals on paper
- 多重財務責任：房貸、學貸、子女
- 開始進入收入高峰期
- 每年增加儲蓄率 1-2%
- 資產配置逐步調整至 70-80% 股票、20-30% 債券
- 開始具體規劃退休目標
50s — The Catch-Up Phase:
50s — 追趕期：
- Take advantage of catch-up contributions (401k allows an extra $7,500/year for those 50+)
- Shift toward wealth preservation and risk reduction
- Adjust allocation to 60% equities, 40% bonds (or more conservative)
- Start planning your Social Security claiming strategy
- 善用 catch-up contributions（401k 50 歲以上可額外存 $7,500/年）
- 轉向財富保全、降低風險
- 配置調至 60% 股票、40% 債券（或更保守）
- 開始規劃社會安全金領取策略
60s — The Final Sprint:
60s — 最後衝刺：
- Target: 8-10x your annual salary saved
- Optimize Social Security timing (delaying to age 70 maximizes your benefit)
- Allocation: 40-50% equities, 50-60% bonds/fixed income
- Build a withdrawal strategy
- 目標：已存 8-10 倍年薪
- 優化社會安全金領取時機（等到 70 歲可最大化給付）
- 配置：40-50% 股票、50-60% 債券/固定收益
- 建立提領策略
4. Emergency Fund
4. 緊急備用金
How Much to Save
該存多少
| Situation | Recommended Emergency Fund |
|---|---|
| Dual-income household, stable jobs | 3 months of expenses |
| Single income, stable job | 3-6 months of expenses |
| Freelancer / Contract worker | 6-12 months of expenses |
| Unstable industry | 6-12 months of expenses |
| Family with chronic health issues | 6-12 months of expenses |
| 情況 | 建議備用金 |
|---|---|
| 雙薪家庭、穩定工作 | 3 個月支出 |
| 單薪、穩定工作 | 3-6 個月支出 |
| 自由工作者/接案 | 6-12 個月支出 |
| 產業不穩定 | 6-12 個月支出 |
| 家庭有慢性健康問題 | 6-12 個月支出 |
Starting from zero: Build it step by step — $500 first, then 1 month, then 3 months, then your full target.
如果從零開始： 先存 $500 → 1 個月 → 3 個月 → 完整目標，循序漸進。
Where to Keep It
該放哪裡
- High-Yield Savings Account (HYSA): Top choice — rates can reach 4-5% APY in 2026, FDIC-insured up to $250,000
- Money Market Account: Good if you need more immediate access (check-writing, debit card)
- Avoid: CDs (locked up), brokerage accounts (volatile), regular savings accounts (zero interest)
- 高利活存 (HYSA)：首選，2026 年利率可達 4-5% APY，FDIC 保障 $250,000
- 貨幣市場帳戶：適合需要更即時提取（可開支票/使用簽帳卡）
- 不要放在：定存（鎖住）、券商帳戶（波動）、一般活存（零利息）
The Reality Check
現實數據
- Only 47% of Americans can cover a $1,000 emergency expense with savings (Bankrate 2026)
- 55% of adults have 3 months of expenses saved (Federal Reserve 2024)
- 30% of adults cannot sustain 3 months of expenses by any means
- 只有 47% 的美國人能用儲蓄支付 $1,000 的突發支出（Bankrate 2026）
- 55% 的成年人存了 3 個月支出（Federal Reserve 2024）
- 30% 的成年人無論用什麼方式都無法支撐 3 個月

| Group | Savings Rate |
|---|---|
| U.S. Average | 3.8-4.5% |
| Financial advisor recommendation | 10-15% |
| Fidelity recommendation (incl. employer match) | 15% |

| 極端 FIRE 實踐者 | 70%+ |
By Income Level (Fed 2024 Data)
依收入水平（Fed 2024 數據）
| Annual Income | % with 3-Month Emergency Fund |
|---|---|
| < $25,000 | 24% |
| $25,000-$49,999 | 40% |
| $50,000-$99,999 | 56% |
| $100,000+ | Most do, but 43% still report feeling financially strained (typically due to lifestyle inflation) |
| 年收入 | 有 3 個月備用金的比例 |
|---|
| < $25,000 | 24% | | $25,000-$49,999 | 40% | | $50,000-$99,999 | 56% |
| $100,000+ | 多數有，但 43% 仍自稱財務吃緊（通常因生活膨脹） |
Retirement Savings by Age (Median vs. Mean)
各年齡層退休儲蓄（中位數 vs 平均）
| Age Group | Mean | Median |
|---|---|---|
| 20s | $127,166 | $39,432 |
| 45-54 | $313,220 | $115,000 |
| 55-64 | $537,560 | $185,000 |
| 65-74 | $609,230 | $200,000 |
| All Households | $333,940 | $87,000 |
| 年齡層 | 平均 | 中位數 |
|---|
| 20s | $127,166 | $39,432 | | 45-54 | $313,220 | $115,000 | | 55-64 | $537,560 | $185,000 | | 65-74 | $609,230 | $200,000 |
| 全部家庭 | $333,940 | $87,000 |
The median is a far better reflection of reality than the mean — averages get skewed upward by high-net-worth outliers.
中位數比平均更能反映真實情況——平均被高淨值離群值拉高。
6. Debt Management
6. 債務管理
Avalanche vs. Snowball Method
雪崩法 vs 雪球法
| Feature | Snowball Method | Avalanche Method |
|---|---|---|
| Priority | Smallest balance first | Highest interest rate first |
| Psychological benefit | High — quick wins build momentum | Low — might take longer to see the first payoff |
| Total interest paid | More | Less (mathematically optimal) |
| Best for | People who need motivation | Disciplined, numbers-driven people |
| 特點 | 雪球法 (Snowball) | 雪崩法 (Avalanche) |
|---|---|---|
| 排序 | 餘額最小的優先 | 利率最高的優先 |
| 心理效益 | 高——快速消除一筆債務帶來成就感 | 低——可能要更久才看到第一個成果 |
| 總利息支出 | 較多 | 較少（數學最優） |
| 適合 | 需要動力的人 | 理性、有紀律的人 |
Both methods follow the same core process: pay the minimum on all debts, then throw every extra dollar at the target debt. Once it's paid off, "roll" that payment into the next one.
兩種方法都：先付所有債務的最低還款額，剩餘全部集中攻擊目標債務。還完後，把那筆還款「滾」到下一筆。
The 6% Rule: When to Pay Off Debt vs. Invest
6% 法則：何時先還債 vs 先投資
| Debt Interest Rate | Recommendation |
|---|---|
| > 10% (credit cards, revolving credit) | Always pay off first — no investment can reliably beat a "guaranteed return" of 15-30% |
| 6-10% | Pay off before making non-matched investments |
| < 6% (some mortgages, subsidized student loans) | Consider investing first — historically the stock market returns 7-10% annually |
| Any rate | Always max out your employer's 401k match — that's an instant 50-100% return |
| 債務利率 | 建議 |
|---|---|
| > 10%（信用卡、循環信貸） | 一定先還——沒有投資能穩定打敗 15-30% 的「保證報酬」 |
| 6-10% | 在非配對投資前先還 |
| < 6%（部分房貸、補貼學貸） | 考慮先投資——歷史上股市年化 7-10% |
| 任何利率 | 一定先拿滿雇主 401k match——那是即時 50-100% 的報酬 |
Good Debt vs. Bad Debt
好債 vs 壞債
Good debt (low interest, builds equity or generates income):
好債（低利率、資產增值或產生收入）：
- Mortgage (builds home equity, potentially tax-deductible, historically appreciating asset)
- Student loans (increases earning potential, interest may be tax-deductible)
- Business loans (investing in a future income stream)
- 房貸（累積資產權益、可能可以扣稅、歷史上房價增值）
- 學貸（提升收入潛力、利息可能扣稅）
- 商業貸款（投資在未來的收入來源）
Bad debt (high interest, consumptive or depreciating assets):
壞債（高利率、消費性質或折舊資產）：
- Credit card debt (15-30% APR)
- Payday loans (effective annual rates can hit 400%)
- Auto loans (cars depreciate the moment you drive off the lot)
- 信用卡債（15-30% APR）
- 發薪日貸款（有效年利率可達 400%）
- 車貸（車子一買就折舊）
The gray area: If a degree doesn't boost your income, that student loan starts looking like bad debt. And credit card debt is a non-issue if you pay it off in full every month.
灰色地帶： 如果學位不能增加收入，學貸就變成壞債；信用卡如果每月全額繳清就不是問題。
7. Tax-Advantaged Account Strategy: Order of Operations
7. 稅務優惠帳戶策略：資金投入順序
Here's the recommended priority order for funding your accounts (U.S.-based):
以下是建議的優先順序（以美國為例）：
Step 1: 401(k) Up to the Employer Match
第一步：401(k) 至雇主 Match 上限
- Capture the full employer match — it's an instant 50-100% return on your money
- Example: If your employer matches 50% of the first 6% of your salary, contribute at least 6%
- 拿滿雇主配對——這是即時 50-100% 的報酬
- 例：雇主配對薪資 6% 的 50%，那你至少要存 6%
Step 2: Max Out Your HSA (If Eligible)
第二步：HSA 存滿（如果有資格）
- Triple tax advantage: Tax-deductible contributions, tax-free growth, tax-free withdrawals for medical expenses
- 2026 limits: $4,400 individual / $8,750 family
- Requires a High Deductible Health Plan (HDHP)
- Pro tip: Keep your medical receipts — you can reimburse yourself tax-free years later
- 三重免稅：存入扣稅、成長免稅、醫療支出提領免稅
- 2026 年上限：個人 $4,400 / 家庭 $8,750
- 須搭配高自付額健康保險 (HDHP)
- 小技巧：保存醫療收據，多年後仍可免稅報銷
Step 3: Max Out Your Roth IRA
第三步：Roth IRA 存滿
- 2026 limit: $7,000/year ($8,000 if 50+)
- Tax-free growth and tax-free withdrawals
- Income limits apply; if you're over, use the Backdoor Roth strategy
- Expect a higher tax rate in retirement? Go Roth. Expect a lower rate? Go Traditional.
- 2026 年上限：$7,000/年（50 歲以上 +$1,000）
- 成長與提領都免稅
- 有收入上限；超過可用 Backdoor Roth 策略
- 預期退休後稅率更高 → 選 Roth；預期更低 → 選 Traditional
Step 4: 401(k) Up to the Annual Limit
第四步：401(k) 存至上限
- 2025 limit: $23,500 ($31,000 if 50+)
- Go back to your 401(k) and fill up the remaining contribution room
- 2025 年上限：$23,500（50 歲以上 +$7,500）
- 回到 401(k) 把剩餘額度填滿
Step 5: Mega Backdoor Roth (If Your Plan Allows It)
第五步：Mega Backdoor Roth（如果公司計畫允許）
- Some employer plans allow after-tax contributions that can be converted to Roth
- This unlocks even more tax-free growth potential
- 部分雇主計畫允許稅後存入，轉換至 Roth
- 可進一步增加免稅成長空間
Step 6: Taxable Brokerage Account
第六步：一般應稅券商帳戶
- Once all tax-advantaged accounts are maxed, invest through a regular brokerage
- Favor tax-efficient index funds to minimize tax drag
- 以上都存滿後，用一般帳戶投資
- 選擇稅務效率高的指數基金以減少稅務拖累
8. Real-World Examples & Cultural Differences
8. 實際案例與文化差異
Budget Allocation at Different Income Levels (50/30/20, After-Tax)
不同收入水平的預算分配（50/30/20，稅後）
Annual income: $50,000 (after-tax ~$40,000):
年收入 $50,000（稅後約 $40,000）：
| Category | Monthly | Annual |
|---|---|---|
| Needs (50%) | $1,667 | $20,000 |
| Wants (30%) | $1,000 | $12,000 |
| Savings (20%) | $667 | $8,000 |
| 類別 | 月 | 年 |
|---|
| 需要 (50%) | $1,667 | $20,000 | | 想要 (30%) | $1,000 | $12,000 | | 儲蓄 (20%) | $667 | $8,000 |
Challenge: Tight margins. Start by building a $1,000 emergency fund, then gradually increase your savings rate. Even 5% ($208/month) is a solid start.
挑戰：空間有限。先建立 $1,000 備用金，再逐步提高儲蓄率。即使 5%（$208/月）也是好的開始。
Annual income: $100,000 (after-tax ~$75,000):
年收入 $100,000（稅後約 $75,000）：
| Category | Monthly | Annual |
|---|---|---|
| Needs (50%) | $3,125 | $37,500 |
| Wants (30%) | $1,875 | $22,500 |
| Savings (20%) | $1,250 | $15,000 |
| 類別 | 月 | 年 |
|---|
| 需要 (50%) | $3,125 | $37,500 | | 想要 (30%) | $1,875 | $22,500 | | 儲蓄 (20%) | $1,250 | $15,000 |
The biggest risk here is lifestyle inflation. 43% of people earning over $100K still report feeling financially strained. Key moves: max out your 401k, capture the full employer match, and start thinking about tax optimization.
主要風險是生活膨脹 (Lifestyle Inflation)。43% 年收超過 $100K 的人仍自稱財務吃緊。重點：401k 存滿、拿滿雇主 match、考慮稅務優化。
Annual income: $200,000 (after-tax ~$140,000):
年收入 $200,000（稅後約 $140,000）：
| Category | Monthly | Annual |
|---|---|---|
| Needs (50%) | $5,833 | $70,000 |
| Wants (30%) | $3,500 | $42,000 |
| Savings (20%) | $2,333 | $28,000 |
| 類別 | 月 | 年 |

| 需要 (50%) | $5,833 | $70,000 | | 想要 (30%) | $3,500 | $42,000 | | 儲蓄 (20%) | $2,333 | $28,000 |
At this level, 20% is a floor, not a ceiling. High earners should target a 25-40% savings rate. Priority: max out all tax-advantaged accounts first (401k + HSA + IRA = ~$35,000+/year), then funnel the rest into taxable accounts. Tax optimization becomes critical.
20% 是地板而非天花板。高收入者應目標 25-40% 儲蓄率。優先把所有稅務優惠帳戶存滿（401k + HSA + IRA = ~$35,000+/年），剩餘投入應稅帳戶。稅務優化變得關鍵。
Dual-Income Household Strategies
雙薪家庭策略
Three common models:
三種常見模式：
- Fully merged: All income flows into a joint account. Research shows that couples who fully merge tend to accumulate higher net worth — sometimes 2x that of couples who keep finances separate.
- Fully separate: Each person manages their own money and splits shared expenses by agreement. Works well for remarried couples or those who value financial autonomy.
- Hybrid model (most popular): Joint account covers shared expenses (housing, bills, groceries) + individual accounts for personal spending. Best of both worlds — transparency and autonomy.
- 完全合併：所有收入匯入共同帳戶。研究顯示完全合併的伴侶往往累積更高淨值——有時是分開帳戶的 2 倍。
- 完全分開：各管各的錢，協議分攤共同支出。適合再婚或重視自主權的人。
- 混合模式（最多人用）：共同帳戶支付共同支出（住房、帳單、食物）+ 個人帳戶支付個人消費。兼顧透明與自主。
When incomes are unequal: Split proportionally. If Partner A earns $60K and Partner B earns $40K, A covers 60% and B covers 40% of shared expenses.
收入不均等時：用比例分攤。如果 A 賺 $60K、B 賺 $40K，A 出 60%、B 出 40% 的共同支出。

Wrap-Up: Your Action Checklist
總結：可執行的行動清單
- Pick a budgeting method that fits your style: 50/30/20 for balanced beginners, 80/20 for minimalists, zero-based for full control
- Calculate your FI Number: Annual expenses x 25 (standard) or x 33 (conservative / early retirement)
- Set your savings rate based on your target retirement age: Retire at 65 = save 15%, at 55 = save 25-35%, at 45 = save 50-75%
- Fund accounts in the right order: Employer match, then HSA, then Roth IRA, then max 401k, then taxable brokerage
- Build your emergency fund: 3-6 months of expenses in a high-yield savings account
- Use the 6% rule to decide whether to pay off debt or invest first
- Adjust your asset allocation by life stage: Aggressive when young (more equities), gradually shifting conservative with age
- Dual-income households: consider the hybrid account model and split shared costs proportionally when incomes differ
- 選一個適合自己的預算方法：50/30/20 平衡入門、80/20 極簡、零基預算完全掌控
- 算出你的 FI Number：年支出 x 25（標準）或 x 33（保守/早退休）
- 依退休目標設定儲蓄率：65 歲退休存 15%、55 歲存 25-35%、45 歲存 50-75%
- 照順序投入帳戶：雇主 match → HSA → Roth IRA → 401k 存滿 → 應稅帳戶
- 建立緊急備用金：3-6 個月支出，放高利活存
- 用 6% 法則決定先還債或先投資
- 依人生階段調整配置：年輕偏積極（多股票），隨年齡逐步轉保守
- 雙薪家庭考慮混合帳戶模式，收入不等用比例分攤
