Frequently Asked Questions
How is overtime pay calculated in Thailand?
Under the Thai Labor Protection Act, workday overtime pays 1.5Γ your hourly rate. Working on a weekly holiday within normal hours pays 2Γ, overtime beyond that pays 3Γ, and work on traditional or annual holidays pays 3Γ. This tool applies these multipliers per tier.
How do I get my hourly rate from a monthly salary?
For a monthly salary, divide by contractual work hours β a common Thai basis is 26 work days Γ 8 hours = 208 hours per month, so monthly salary Γ· 208 gives the hourly rate.
Can I use this for countries outside Thailand?
Yes. Enter your own multiplier tiers as hour amounts: for example US time-and-a-half goes in the Γ1.5 workday tier and double time in the Γ2 tier. The math is plain rate Γ multiplier Γ hours.
Does the monthly estimate include overtime every day?
Yes β it multiplies your current daily total by the work-days figure. Set OT hours to 0 for a regular-day baseline, or average OT hours across days for a realistic month.
