About this tool
Calculate your net salary — see what actually lands each month after social security and withholding tax. Just enter your salary and the tool shows your take-home pay with each deduction broken out. It's ideal for negotiating pay, comparing job offers, or planning monthly budgets.
Social security is 5% of salary (max 750 THB), and tax is estimated from annual income using the Revenue Department's progressive brackets. Your real figure depends on your personal deductions. For detailed tax planning use the tax calculator, which already includes the insurance-premium deductions.
As a feel for the numbers: on a ฿25,000 salary the social security contribution is ฿750 and withholding tax is small, so take-home is roughly ฿24,000. At ฿50,000 the tax bite grows to a few thousand baht a month, and at ฿100,000 it matters a lot — which is why comparing two job offers on gross salary alone can mislead. Run both offers through the tool and compare take-home instead. Social security also buys real benefits (medical care, unemployment and pension contributions), so it isn't money lost.
