What is VAT?

VAT stands for "Value-Added Tax", which is intended to be a tax on the added value to a starting good or service, or a state of nature, and is determined as a percentage of the end price when paid by an end consumer. This is ensured through a somewhat complicated scheme in which each person or company adding value to a product is reimbursed for the tax, until it ends up being paid for by the end consumer (which can also be a judicial person). VAT is one of the primary sources for budget funds in many countries. As it is a tax on consumption, shared proportionally by all who consume, it is deemed unfair to people in a poorer economic situation by people who believe in equality of outcome.

Where it gets tricky is in the consistency of application of the tax in different countries that use it. VAT is mostly prevalent in Europe (and thus the EU), but it is adopted by other countries as well, even though in some places the name might be different.

For example, in some countries VAT is applied universally at the same rate, with rates commonly between 15% and 25%. There might be certain industries or categories of products or services, which are excluded from VAT, for example educational services and institutions, books and schoolbooks, basic foods and/or drinks, transportation and so on. In some cases, it is an industry considered on some, usually arbitrary basis, to be key for the functioning of the whole economy, e.g. tourism in countries where it contributes a significant percentage of GDP. In many countries there are different VAT levels for different sets of products and services. For example, the official VAT rate might be 20%, but VAT for books might be 5% while VAT for travel and accommodation services might be 10%. This is why having a VAT calculator handy can be quite useful.

VAT calculation formula

The formula for calculating VAT-inclusive prices used in this VAT calculator is easy as it is just a percent increase over the base price. The equation is simply:

Price with VAT = Base Price x (100% + VAT(%))

For example, to increase a base price of 100 euro with a tax of 15% we need to multiply €100 x (100% + 15%) = €100 x 115% = €115. This is equivalent mathematically to multiplying 100 euro by 1.15.

The formula for how much tax you need to add to a base price is:

VAT = Base Price x VAT(%)

So if the base price is €20 and the tax rate is 10%, the VAT is equal to €20 x 10% = €2. This is the same as multiplying 20 by 0.1.

VAT calculation examples

Example 1: If you know the price without VAT is €80 and the VAT rate is 20%, what is the final VAT-inclusive price? Using the first equation above we get €80 x (100% + 20%) = €80 x 120% = €80 x 1.2 = €96.

Example 2: If you know the VAT rate for the product you are buying is 20% and you know the base price is $50, what is the absolute value of the value-added tax? Using the second formula above we get $50 x 20% = $10.

Example 3: If you know the VAT-inclusive price for a good or service is €150 and the VAT rate is 20%, what is the amount that the merchant or service provider actually pockets? You can reverse the first formula by substituting the base price with the final one and by using division instead of multiplication. So the price without VAT is calculated as €150 / (100% + 20%) = €150 / 120% = €150 / 1.20 = €125.

Is it a VAT-inclusive price?

Before adding VAT to a price you need to check the tax has already been included in it. In many countries, e.g. in the EU, merchants and service providers are obliged to post the VAT-inclusive price on the product offer, be it in a physical or online store. Some merchants will put the base price AND the VAT price, while others will list just the VAT-inclusive price. This will likely also be noted next to the price, with an asterisk next to it, in the footer of each page, or, in some cases, in the terms and conditions. If in doubt: always ask. The merchant in many cases is obliged to tell you the final price you need to pay.

Where it gets more complicated is when both the provider and the consumer are VAT-registered entities. In this case, it is very common to exchange price information with value-added tax excluded, since the consumer entity will get reimbursed for the VAT tax, usually at the end of the month, so they only care about the base price. Still, cash flow might be an issue for larger purchases, so the VAT price should always be considered. Our calculator is especially useful in such cases.
