FAQ
Can it work out take-home pay?
No. Income tax, resident tax and social insurance depend on the number of dependants, the municipality, the health insurance society and whether you are over 40 (nursing-care insurance). Take-home is often said to be 75-85% of gross, but that range spans tens of thousands of yen a month, so read it off a payslip or ask your employer if you need the real number.
Can I check I am above the minimum wage?
Use "salary to hourly" and compare against your prefecture's minimum wage. Note that the minimum-wage test excludes attendance allowances, commuting and family allowances, overtime premiums and bonuses — a different list from the one used for the overtime base, so do not reuse one number for both. The minimum wage itself is revised every year, so take the current figure from the Ministry of Health, Labour and Welfare or your prefectural labour bureau.
1,500 yen an hour or 250,000 a month — which is better?
They cannot be compared until one is converted. At 160 scheduled hours a month, 250,000 works out to 1,562 an hour, so the salary is slightly ahead; at 170 hours it is 1,470 and the order reverses. What actually decides these comparisons is scheduled hours rather than the headline figure: the same salary shifts by around 10% in hourly terms between 105 and 125 days of annual holiday.
What if fixed overtime pay is included?
Putting the whole advertised figure into "salary to hourly" inflates the result. Fixed overtime is supposed to be shown separately, so from a line like "280,000 a month (includes 60,000 for 45 hours of fixed overtime)", enter only the 220,000. Hours worked beyond the fixed allowance must still be paid separately, and those can be worked out under "overtime".
I am under 40 hours a week but I am told I get overtime pay.
That happens when the employer's scheduled hours are shorter than the statutory 8. On a 7-hour contract, the eighth hour is inside the statutory limit, so a premium is not legally required — but many work rules promise one for anything beyond scheduled hours, and the contract then governs. Since you choose the rate here, count that hour at x1.0 under "income from an hourly wage" instead.
Are the amounts I type sent anywhere?
No, and nothing is stored. The arithmetic happens in the page, salary figures never reach a server, and closing the tab clears the inputs.
