# A VAT calculator that knows your rate

Every example was run through Ratio 0.6.1 on 15 October 2026. These use Germany's 19% rate.

Pick your region in Settings once, and Ratio knows its standard VAT, GST or sales tax rate. Type “+ VAT” to add it, “without VAT” to take it out, or “VAT in” to see the tax on its own.

## Add it, remove it, find it

| 1000 + VAT | 1,190 |
| --- | --- |
| 1190 without VAT | 1,000 |
| VAT in 1190 | 190 |
| 1000 + VAT 7% | 1,070 |

## A whole invoice

| net = 3 * 850 + 1200 | 3,750 |
| --- | --- |
| net + VAT | 4,462.5 |
| VAT in prev | 712.5 |

## Every name for tax

TVA, MwSt, IVA, GST or simply tax: Ratio understands them all. For a different rate, write it after the word.

| 89.99 + sales tax 8.875% | 97.98 |
| --- | --- |
| 1000 + MwSt | 1,190 |
| 1000 + TVA | 1,190 |

## Margins, markups and rounding

| 80 + 25% margin | 106.67 |
| --- | --- |
| margin(80, 100) | 20% |
| markup(80, 100) | 25% |
| 12.37 to nearest 0.05 | 12.35 |

On the Mac, it works in Terminal too: `ratio --vat 20 "1000 + VAT"`. More in the [syntax reference](https://useratio.app/docs#vat).

Ratio runs on [Mac](https://useratio.app/), [Windows](https://useratio.app/notepad-calculator-windows) and [Linux](https://useratio.app/notepad-calculator-linux) with the same engine, so every example here gives the same answer on all three.

## Questions

**How do I add VAT to a price on a Mac or PC?** In Ratio, type “1000 + VAT”. It uses the standard rate of your region (1,190 with Germany's 19%). Write “1000 + VAT 7%” for another rate.

**How do I remove VAT from a gross price?** Type “1190 without VAT” for the net price (1,000), or “VAT in 1190” for the tax alone (190).
