How to Use the Wage Converter

Switch between "Hourly → Yearly" and "Yearly → Hourly" to estimate hourly, monthly and yearly income in real time. The hours per day and days per month are editable, so you can match your own work pattern.

  1. Choose a direction (Hourly → Yearly or Yearly → Hourly).
  2. Enter the hourly wage or the yearly income.
  3. Adjust hours per day (default 8) and days per month (default 20) as needed.
  4. The hourly, monthly and yearly figures appear below. Use "Copy Result" to paste them anywhere.

Conversion is live: results update the moment you type. There is no button to press — every change to the amount, hours per day or days per month recalculates instantly. The assumptions used (hours per day and days per month) are always shown beneath the result, so you can see exactly which conditions produced the figures. The Examples (click to try) chips at the top set both the amount and the assumptions and show a result right away.

Worked example (¥1,200/hr → yearly)

An hourly wage of ¥1,200, with the assumption "8 hours per day, 20 days per month", gives a monthly income of 1,200 × 8 × 20 = ¥192,000 and a yearly income of 192,000 × 12 = ¥2,304,000. Change the assumption to "6 hours per day, 16 days per month" and the monthly drops to ¥115,200 and the yearly to ¥1,382,400 — showing how much the same wage varies with the hours worked.

How It Is Calculated

  • Monthly = hourly wage × hours per day × days per month
  • Yearly = monthly × 12
  • Hourly (from yearly) = yearly ÷ (12 months × days per month × hours per day)

When This Helps

When a part-time listing shows only an hourly rate and you want to know what full-time work adds up to over a year. Or the reverse — turning a stated salary back into an hourly rate to compare with how you work now. These figures are estimates and exclude overtime, bonuses and allowances, so treat them as a rough comparison.

Frequently Asked Questions

Is my data sent to a server?
No. All calculations happen entirely in your browser. The wages and salaries you enter are never transmitted to or stored on any external server. You can use this tool with complete confidence.
How are monthly and yearly income calculated?
Monthly income is hourly wage × hours per day × days per month, and yearly income is monthly × 12. You can freely change the hours per day (default 8) and days per month (default 20). Overtime, bonuses and allowances are not included.
How is the hourly rate derived from a yearly salary?
It is yearly salary ÷ (12 months × days per month × hours per day), giving an approximate amount per hour. This is an estimate only and does not account for bonuses, allowances or social-insurance deductions.
