計算結果
重點速覽：Annual income conversion turns an hourly wage into annual and monthly income using working-hour assumptions, so that pay quoted in different ways (hourly, daily, monthly) can be compared on a common basis. Annual income = hourly wage x hours per week x weeks per year; monthly income = annual income / 12. WARNING: The result is gross (pre-tax) nominal income — it does not deduct Salaries Tax or Mandatory Provident Fund (MPF) contributions, nor does it include overtime, bonuses, commissions or the 13th-month payment. In Hong Kong, the Statutory Minimum Wage has been HK$42.1 per hour since 1 May 2025.
計算公式
年收入 = 時薪 × 每週工時 × 每年工作週數。
月收入 = 年收入 ÷ 12。
$$\text{AnnualIncome} = \text{HourlyWage} \times \text{HoursPerWeek} \times \text{WeeksPerYear}$$$$\text{MonthlyIncome} = \dfrac{\text{AnnualIncome}}{12}$$使用說明
- Enter your hourly wage.
- Enter hours per week and weeks actually worked per year (lower it for unpaid leave).
- View the converted gross annual and monthly income.
以每週工作 40 小時、每年 52 週為例，不同時薪換算成稅前年收入與月收入的對照表
| 時薪 | 年收入 (40h × 52週) | 月收入 |
|---|---|---|
| HK$50 | HK$104,000 | HK$8,667 |
| HK$100 | HK$208,000 | HK$17,333 |
| HK$150 | HK$312,000 | HK$26,000 |
| HK$200 | HK$416,000 | HK$34,667 |
| HK$300 | HK$624,000 | HK$52,000 |
以每週 40 小時、每年 52 週計:年收入 = 時薪 × 40 × 52，月收入 = 年收入 ÷ 12。作為參考，香港法定最低工資自 2025 年 5 月 1 日起為每小時 HK$42.1，按同一工時假設換算約為年收入 HK$87,568、月收入約 HK$7,297。以上皆為稅前名義收入，實際到手須扣除薪俸稅與強積金。數字僅供參考。
理財情境案例
時薪 HK$150 全職：換算成年收入與月收入
以時薪 HK$150、每週 40 小時、每年 52 週計:每週收入 = 150 × 40 = HK$6,000，年收入 = 6,000 × 52 = HK$312,000，月收入 = 312,000 ÷ 12 = HK$26,000。這就是把時薪年化、方便填報與比較的標準算法。
若這份工作有一個月無薪假 (實際只做 48 週)，年收入會降到 HK$288,000，比名目少 HK$24,000。因此填報或做預算時，宜按實際休假情況調整週數;同時別忘了這是稅前數字，扣除薪俸稅與強積金後，可自由運用的淨收入會更低。
兼職 vs 全職：同樣時薪 HK$120，年收入差一倍
一份兼職時薪 HK$120、每週只做 20 小時、一年 48 週，年收入 = 120 × 20 × 48 = HK$115,200，月收入約 HK$9,600。若換成同樣時薪的全職 (每週 40 小時、一年 52 週)，年收入則約 HK$299,520——差距接近一倍。
這說明時薪相同不代表年收入相同，關鍵在於「總工時」。用年收入比較工作機會時，務必用實際能拿到的工時估算;同時要留意兼職往往缺少全職的有薪假期、醫療、雙糧等，整體報酬未必如時薪數字般接近。
常見問題
How do I convert an hourly wage to annual and monthly income?
Multiply the hourly wage by hours per week and by weeks per year to get annual income, then divide by 12 for monthly income. Example: HK$80/hour x 40 hours x 52 weeks = HK$166,400 per year, or about HK$13,867 per month.
Is the result gross or net, and how much lower is take-home pay?
The figure shown is gross, before tax. In Hong Kong, employees generally contribute 5% of relevant income to the Mandatory Provident Fund (MPF), subject to a cap, and Salaries Tax applies on a progressive scale with generous allowances. Take-home pay is therefore lower than the gross figure shown here.
What is this conversion useful for?
It lets you compare jobs quoted in different units (hourly vs monthly), supports salary negotiation, monthly budgeting and household cash-flow planning, and is often needed when applying for mortgages or other loans.
How does it compare with Hong Kong income levels?
At the Statutory Minimum Wage of HK$42.1/hour, working 40 hours a week for 52 weeks gives an annual income of about HK$87,568 — a useful benchmark at the low end of the pay scale.
