Tip, Discount & Tax Calculator

Three small calculations come up constantly and none of them is worth a dedicated app: how much to tip, what something costs after a discount, and how much tax to add or extract. This free tip calculator handles all three in one place.\n\nThe tip tab splits a bill between any number of people and can round the total up, which makes the per-person figure cleaner and saves everyone hunting for coins. Presets cover the usual range, though what counts as usual varies enormously — 15 to 20 per cent is typical in the US, ten is common across much of Europe where it is often optional, and tipping is unusual in Japan.\n\nThe discount tab shows both the final price and what you saved, which is the number that actually decides whether a sale is worth it. The tax tab does something most calculators skip: it works backwards from a tax-inclusive price. That is a genuinely different calculation, because subtracting eight per cent from a price that already includes eight per cent tax gives the wrong answer — the tax was applied to the smaller pre-tax figure, so you divide rather than subtract.\n\nEverything runs in your browser with eight currencies supported. Pair it with the Percentage Calculator for general percentage maths, or the Invoice Generator when the discount and tax are going onto a real invoice.
