Salary Converter: Monthly, Daily, Hourly, and Annual Pay (21.75-Day Basis)
The usual conversion is monthly pay divided by 21.75, then by 8, to get an hourly rate; annual pay is normally monthly times 12, with a 13th month or bonus added separately.
When you need a pay conversion
Comparing offers, quoting freelance work, and checking overtime all require the same figure expressed on a different basis.
In a negotiation the useful number is not the monthly salary but the hourly rate after actual hours, because that is what puts a five-day week, a six-day week, and permanent overtime on one page.
- Two offers with different bonus structures and different weekly hours.
- Quoting a day rate or hourly rate for contract work.
- Checking whether an overtime payment matches the legal base.
The 21.75 convention and its limits
21.75 is the statutory average number of paid days per month: 365 minus 104 weekend days, divided by 12. It is the basis for daily pay and overtime, not a count of the days you actually worked this month.
So hourly = monthly ÷ 21.75 ÷ 8, and daily = monthly ÷ 21.75. Annual = monthly × 12 plus any 13th-month pay and bonus. When comparing packages, ask whether the figure is before or after tax and whether equity and allowances are included.
- A two-day weekend, a single rest day, and alternating weeks produce very different real hourly rates at the same monthly pay; recompute with actual working days.
- Overtime is commonly 1.5× on workdays, 2× on rest days, and 3× on statutory holidays; check your local rules.
- Freelancers carry their own social insurance and tax, so a day rate is not simply eight times the employed hourly rate.
Limits
The conversion excludes social insurance and housing fund contributions, income tax, bonus conditions, and equity vesting; purchasing power across cities needs a separate cost-of-living comparison.
For a legally binding figure, use the payslip and local labour regulations rather than a converter.
- Bonus conditions and deferred portions are defined by the contract and company policy, not by arithmetic.
- Equity has to be valued and discounted along its vesting schedule; it is not salary.
FAQ
Why divide by 21.75 instead of 22?
21.75 is the statutory monthly average of paid days, derived from 365 days minus 104 weekend days, divided by 12. It is the basis used for daily pay and overtime. 22 is a rough approximation, not the calculation base.
Is annual pay monthly times 12 or 13?
By default 12. If the employer pays a 13th month or a bonus, add it explicitly; do not assume it is included in the monthly figure.
How much more is a two-day weekend worth?
At the same monthly salary, working six days a week lowers the effective hourly rate, because the same money is spread over more hours. Compute both with actual working days to see the gap.
