Hourly Wage Calculator

How to Use

Choose the tab that matches the information you have on hand — "From Annual Salary," "From Hourly Wage," or "From Monthly Pay" — and enter your figure. Below the tabs, set your work days per month and hours per day to match your actual schedule. The defaults (20 days, 8 hours) suit a standard full-time schedule, but you can change them to reflect part-time, reduced hours, or any other arrangement.

Two scenarios stand out as the most popular uses. The first is comparing full-time employment with freelance or contract work: when you receive a monthly project rate, enter it as monthly pay, adjust the days and hours you plan to work, and you instantly see the hourly equivalent to compare with your current salary. The second is sizing up a side job: converting your side gig's hourly rate and your main job's annual salary to the same unit lets you calculate the opportunity cost of every extra hour you commit.

Keep in mind that the result is a gross-pay estimate. Taxes and social insurance are not deducted here, so your actual take-home will be lower. Use this tool as a starting point for comparison, then consult your pay stub or a tax professional for precise figures.

How the Calculation Works

All three conversion directions use straightforward arithmetic. From annual salary: monthly pay = annual ÷ 12, hourly rate = annual ÷ (12 × work days per month × hours per day). From hourly rate: monthly pay = hourly × hours per day × work days per month, annual = monthly × 12. From monthly pay: annual = monthly × 12, hourly rate = monthly ÷ (work days per month × hours per day). All results are rounded down to the nearest whole number.

The default of 20 days and 8 hours has a concrete basis. A typical five-day week with public holidays gives around 240–247 working days per year, which is about 20 days per month. Eight hours reflects the statutory working day set by labor law in many countries. However, the number of days you actually work can shift the hourly rate significantly. At ¥6,000,000 per year, 20 days gives ¥3,125 per hour. If you work 22 days due to overtime or weekend shifts, the rate drops to ¥2,841 — a difference of ¥284. Seeing your real hourly rate based on actual hours worked, rather than the nominal salary figure, reveals the true cost of your time. This approach also works in reverse: freelancers can calculate the annual income needed to match a target hourly rate at a given number of working days.

All figures are pre-tax (gross). Income tax, social security contributions, and other deductions are not included in this calculation.

FAQ

Is the hourly rate the same as my take-home pay per hour?

No. This tool converts gross (pre-tax) figures. Your actual take-home pay is lower after income tax, social insurance premiums, and any other deductions — often 20–30 % less for a salaried employee. For your real net hourly rate, start here for the gross conversion, then apply your typical deduction rate or check your pay stub.

How do I choose the right number of work days per month?

Divide your total working days per year by 12. A five-day week with holidays usually gives 240–245 days a year, so about 20 days per month. A four-day week comes to roughly 17–18 days. If your schedule varies, use your average. Include overtime days if you want to see your real hourly rate based on actual time worked.

Can I use this as a freelancer or self-employed?

Yes. Enter your monthly client revenue in the "From Monthly Pay" tab, then set the days and hours you plan to bill. The result shows your effective hourly rate. You can also run the numbers in reverse to find the annual income you need to match a target hourly rate. Note that this tool does not account for business expenses, VAT/sales tax, or self-employment taxes.

Why does the result change when I go back and forth between modes?

Rounding is applied at each step — all values are rounded down to the nearest whole number. This means a small amount (usually less than one unit of currency) may be lost when you convert in a round trip. This is expected behavior for a quick-estimate tool.
