A free take-home pay calculator for Cambodia: tax on salary and NSSF, line by line

01 / Overview
Overview
Workers and small employers in Cambodia rarely see how a salary becomes take-home pay, so Prak Khae shows it line by line: the five steps of the tax on salary, the rebate for a spouse and children, and the NSSF contributions, in riel or dollars at the official rate. It also works backwards from the pay a person wants to the salary to ask for. Each rule is a number read at its source with the day it was read, the engine reproduces published worked examples in its tests, and nothing typed leaves the device.

Live at prak-khae.vercel.app since 1 October 2026 as a static site with no account and no server of its own. It is an estimate, not a payslip and not tax advice, and it says so on the page and on its printed sheet. It launched this month, so no usage is claimed.
