The premium for working while the rest of the country sleeps
Philippine labor law treats night work as harder on the body, so it pays a built-in bonus. For every hour you work between 10pm and 6am, you earn an extra slice on top of your normal hourly pay. The rule this calculator follows sets that slice at 10 percent of the hourly rate, which is the figure the Department of Labor and Employment (DOLE) sets in its Labor Code handbook. This is one of the most overlooked entitlements in the country, partly because it is small per hour and partly because it hides inside a single combined payslip line. The tool isolates it so you can see exactly what the night portion is worth and check that your employer actually paid it.
From a monthly salary down to one night hour
The differential is a percentage of your hourly rate, so the chain starts with turning your monthly salary into an hourly figure. The calculator divides the monthly salary by a standard 26 working days to get a daily rate, then by 8 to get the hourly rate. The night differential is then 10 percent of that hourly figure for each qualifying hour. Note what this number is and is not. It is the extra night portion alone, paid on top of the base hour. It is not overtime and it is not a holiday premium. If a shift is also overtime, or falls on a rest day or holiday, those premiums apply as well, and the night differential is layered on top, which can stack into a meaningfully larger figure. Treat the 26-day divisor and the 10 percent rate as the convention this tool uses, and confirm both against the latest DOLE issuances, since some firms use a different day count.
A PHP 30,000 earner working 40 night hours
Take a monthly salary of PHP 30,000 and 40 hours worked inside the 10pm to 6am window over a pay period. Using the rates this calculator applies, the steps are below.

The extra PHP 577 is the part you should look for on your payslip. Over a year of steady night shifts it adds up to several thousand pesos that some workers never notice is missing. If your employer lists pay as a single combined figure, ask for a breakdown, because the differential should appear as its own line or be clearly identifiable within the gross.
Is the night differential taxed?
For most employees the differential is ordinary taxable income and rolls into the withholding tax on your salary. There is one important exception. If you are a statutory minimum-wage earner, your night-shift differential, along with your overtime, holiday pay, and hazard pay, is exempt from income tax under the rules the Bureau of Internal Revenue (BIR) administers. So whether the premium is fully kept or partly taxed depends on whether you sit at the minimum wage. This tool reports the gross differential, before any tax, so a minimum-wage earner keeps the whole figure while a higher earner sees it after withholding on the payslip.
What exactly counts as a night-shift hour?
Only the hours actually worked between 10pm and 6am qualify. If your shift runs from 8pm to 4am, the first two hours, 8pm to 10pm, earn no differential, while the six hours from 10pm to 4am do. Enter only those qualifying hours into the tool. A short meal break inside the window that is unpaid would normally be excluded too.
Can my employer pay a higher night rate than 10 percent?
Yes. The 10 percent the calculator applies is the legal minimum, not a ceiling. Some companies, particularly BPOs and hospitals that rely heavily on night staffing, offer a richer night premium through a collective bargaining agreement or company policy. If your contract states a higher percentage, your actual differential will exceed what this tool shows. Use the result as the floor your pay should never drop below, and confirm the current minimum with DOLE.
