Rounding
Good to know
- This is a reference calculation. For tax decisions, follow a tax adviser or the guidance of your tax authority.
- Rates are picked by the date of the sale. Temporary rates, such as Vietnam's 8%, Thailand's 7% and Mexico's 8% in the border regions, appear only for dates inside their period; for future dates the calculator shows the changes announced when the rates were last checked. When a period ends, or a checked source does not reach the date you chose, a note under the date says so.
- Not in the list: the United States (sales tax set by states, counties and cities and added on top of prices) and Brazil (several taxes, some calculated inside the price, changing to CBS and IBS from 2026). For one known rate, use "Other rate".
- France is given for the mainland only (Corsica and the overseas departments have their own rates) and Spain without the Canary Islands (IGIC), Ceuta and Melilla (IPSI). For Portugal, choose the Azores or Madeira under Region.
- Everything runs in your browser. The amounts and items you enter are not sent to LeedyBox or saved.

How to use
- Choose the country and check the date of the sale. The rates in force on that date appear, with what they cover.
- Choose whether to add VAT to a net amount or take it out of a gross amount, then pick a rate or type another one.
- Enter the amount. The net amount, the VAT and the gross amount appear at once, with the calculation before rounding.
- For an invoice, open "Several lines", enter a quantity, a unit price and a rate on each line, and copy the table into a spreadsheet.
- Under Rounding, choose how the VAT is rounded and whether it is rounded on every line or once per rate, as your invoices do.
Frequently asked questions
How do I add VAT to a price?
Multiply the net price by the rate and add the result: at the UK standard rate of 20%, £100 net becomes £100 + £20 = £120. The calculator does the same at any rate and rounds the VAT to the penny.
How do I work out the VAT in a price that includes VAT?
Do not take 20% of the gross price. The VAT is rate ÷ (100 + rate) of it, which HMRC calls the VAT fraction: one sixth at 20% (£120 contains £20), 1/21 at 5%. Dividing the gross price by 1.2 gives the net price.
Should VAT be rounded on every line or on the total?
It depends on the country. HMRC allows the total VAT on an invoice to be rounded down to a whole penny, or line VAT to be rounded consistently; Japan requires one rounding per rate on each invoice. The two methods can differ by a few pence or yen, so choose the one your invoices use.
Why is the result one penny off from my invoice?
Usually because of rounding: half up or down, per line or on the total, and whether the VAT or the net amount was rounded when VAT was taken out. Try the options under Rounding; the line under the result shows the VAT before rounding.
Which countries and rates are included?
The UK, Germany, France, Italy, Spain, Portugal (with the Azores and Madeira), Turkey, Russia, Japan, Korea, China, Taiwan, Thailand, Vietnam, Indonesia and Mexico, each with the rates in force on the date you choose. Every rate links to the official source it was checked against.
Can I use it for US sales tax?
Only for a single known rate: choose any country, enter the combined state and local rate under "Other rate" and use "Add VAT". Sales tax rates differ by state, county and city and are not in the list.
Is anything I enter sent or saved?
No. The calculation runs in your browser; the page only downloads the rate table from leedybox.com and does not save amounts or item names.
