Salary to Hourly Calculator — Complete Guide
An annual salary tells you what a job pays over a year; an hourly rate tells you what each working hour is worth. Converting between them is the only fair way to compare a salaried offer against a contract, a part-time role or a freelance rate.
What this calculator does
Enter a salary and choose whether it is annual, monthly or weekly. Then set the hours you work each week, the number of weeks you actually work in the year, and optionally a daily-hours figure for the daily rate. Add an estimated tax rate if you want the net figures too. The result is the equivalent hourly rate, along with the daily, weekly, monthly and annual breakdown.
The formula
annual = salary × period multiplier (1 / 12 / 52)
paid hours = hours per week × working weeks
hourly = annual ÷ paid hours
weekly = annual ÷ working weeks
daily = hourly × daily hours
net hourly = hourly × (1 − tax rate)
The denominator is the key number: a standard full-time year is 40 × 52 = 2,080 paid hours. Change either figure and the hourly rate moves.
A worked example
A $52,000 salary at 40 hours over 52 weeks: paid hours = 2,080, so the hourly rate is 52,000 ÷ 2,080 = $25.00. Daily at 8 hours = $200, weekly = $1,000 and monthly = $4,333. Now suppose the role only pays for 48 working weeks — the same $52,000 now divides by 40 × 48 = 1,920 hours, giving $27.08 per hour. Nothing about the salary changed, but each paid hour is worth more because there are fewer of them.
| Schedule | Paid hours | Hourly rate |
|---|
| 40 h · 52 weeks | 2,080 | $25.00 |
| 40 h · 48 weeks | 1,920 | $27.08 |
| 20 h · 52 weeks | 1,040 | $50.00 |
How to use the result
- Compare against hourly contracts on the same basis — including how many weeks they actually pay for.
- A salaried role often adds paid leave, bonuses, health cover and pension contributions that the raw hourly figure does not capture.
- Part-time workers should enter real hours; halving the hours doubles the equivalent hourly rate.
- Overtime is not modelled — this is the rate for your contracted hours only.
- All figures are gross unless you enter a tax rate; take-home pay will be lower.
Once you know your true hourly rate, a raise is easy to evaluate: a $2,000 annual increase at 2,080 paid hours is worth about 96 cents an hour.
年薪转时薪计算器完整使用指南
年薪说明一份工作一年给多少钱，时薪说明每个工作小时值多少。二者之间的换算是把「固定月薪岗位」与「计时岗位、兼职、自由职业报价」放在同一把尺子上比较的唯一办法。
这个计算器能做什么
输入薪酬金额，并选择它是年薪、月薪还是周薪；再填写每周工时、一年实际工作的周数，以及可选的每日工时（用于换算日薪）。如果填写预估税率，还会给出税后金额。结果是等价的时薪，以及日薪、周薪、月薪、年薪的完整拆解。
计算公式
年薪 = 薪酬金额 × 周期倍数（1 / 12 / 52）
付费工时 = 每周工时 × 年工作周数
时薪 = 年薪 ÷ 付费工时
周薪 = 年薪 ÷ 年工作周数
日薪 = 时薪 × 每日工时
税后时薪 = 时薪 × (1 − 税率)
公式里的分母才是关键：标准全职一年是 40 × 52 = 2,080 个付费工时。只要改动这两个数字中的任何一个，时薪就会变化。
算例演示
年薪 52,000 元、每周 40 小时、全年 52 周：付费工时 = 2,080，时薪 = 52,000 ÷ 2,080 = 25.00 元。按每天 8 小时算，日薪 200 元、周薪 1,000 元、月薪约 4,333 元。若这份工作一年只按 48 个工作周计薪，同样的 52,000 元要除以 40 × 48 = 1,920 小时，时薪变成 27.08 元。薪酬没有变，但每个付费工时的价值提高了，因为工时的总数变少了。
| 工作安排 | 付费工时 | 时薪 |
|---|
| 每周 40 小时 · 52 周 | 2,080 | 25.00 元 |
| 每周 40 小时 · 48 周 | 1,920 | 27.08 元 |
| 每周 20 小时 · 52 周 | 1,040 | 50.00 元 |
如何使用这个结果
- 与计时岗位对比时，务必按同一口径计算，尤其是对方一年实际支付多少周。
- 固定月薪岗位通常还有带薪假、奖金、医疗与公积金等福利，这些是单纯的时薪数字无法体现的。
- 兼职者应填写真实工时；工时减半，等价的时薪会翻倍。
- 加班未单独建模，此处只反映合同约定工时对应的费率。
- 不填写税率时，所有金额均为税前；扣除各项费用后到手收入会更低。
算清真实时薪之后，判断加薪幅度就很容易了：在 2,080 个付费工时下，年薪增加 2,000 元，相当于每小时多约 0.96 元。
