How these calculators work
Each page is a plain calculator with no sign-up: type a figure and the result updates as you go. Under the calculator you will find the formula, a worked example, the official source for the rate (GOV.UK, Revenue, the ATO, Inland Revenue, the Thai Revenue Department) and the date it was last checked. Rates change by law, so the source link is there for you to confirm the figure on the day you need it.
You can also put any of them on your own website with the embed code at the bottom of its page.
