How to Calculate VAT in the UK (With Examples & Steps)
What is Cash Back or Low Interest Calculator?
A Cash Back or Low Interest Calculator helps you compare two popular car buying incentives: taking a cash rebate or accepting a low-rate auto loan. It instantly calculates the total cost and interest paid for both scenarios based on your actual values.
This tool simplifies side-by-side analysis, offering a clear “best option” in seconds. You need only enter the car price, cash back offer, standard and low interest rates, loan term, and down payment—everything else is automatic.
Formula Behind Cash Back or Low Interest Calculator
The calculator computes monthly and total payments for both cases using the standard car loan formula: M = P × r × (1 + r)n / [(1 + r)n - 1], with 'P' as principal, 'r' as the monthly interest rate, and 'n' as number of payments. The “Cash Back” case deducts the rebate before financing at the normal rate; the “Low Interest” scenario uses the full price but at the special low rate. The option with the lower total paid is your winner.

FAQs on VAT Calculator UK: Add or Remove Value Added Tax Online
1. How do I use this UK VAT Calculator?
To use the calculator, simply enter a monetary value into the designated field. Then, select whether you want to add VAT to this amount or remove VAT from it. The calculator will instantly show you the gross amount (with VAT added), the net amount (before VAT), and the total VAT value, based on the standard 20% rate.
2. What is the formula to calculate a price with 20% VAT added?
To add the standard 20% VAT to a price, you multiply the net amount (the price before tax) by 1.20. The formula is: Net Amount × 1.20 = Gross Amount. For example, if a product costs £100 before tax, the price including VAT would be £100 × 1.20 = £120.
3. How do you remove VAT from a total price?
To remove VAT from a total price (the gross amount), you need to divide the price by 1.20. This reverses the addition of the 20% tax. The formula is: Gross Amount / 1.20 = Net Amount. For example, if a product costs £120 including VAT, the original price before tax was £120 / 1.20 = £100.
4. What is the difference between the net amount, gross amount, and VAT?
Understanding these three terms is key to VAT calculations:
- Net Amount: This is the original price of goods or services before any VAT has been added. It is the base price.
- VAT: This is the Value Added Tax itself, calculated as a percentage (usually 20%) of the net amount.
- Gross Amount: This is the final, total price that a consumer pays. It is the net amount plus the VAT amount.
5. If I only know the VAT amount, how can I calculate the net and gross prices?
If you know the VAT amount was calculated at the standard 20% rate, you can find the original net price by dividing the VAT amount by 20 and then multiplying by 100. The formula is: (VAT Amount / 20) × 100 = Net Amount. Once you have the net amount, you can find the gross amount by simply adding the VAT amount back to it (Net Amount + VAT Amount = Gross Amount).
6. Why can't I just subtract 20% to remove VAT from a price?
This is a common misconception. Subtracting 20% from the gross price will give you an incorrect net amount. This is because the original 20% VAT was calculated on the smaller, net amount, not the larger, final gross amount. To correctly reverse the calculation, you must divide the gross price by 1.20, which accounts for the original base the tax was applied to.
7. What is the current standard VAT rate in the UK?
The current standard rate for Value Added Tax (VAT) in the UK is 20%. This is the rate applied to most goods and services. However, some items may be subject to a reduced rate (5%) or be zero-rated (0%). This calculator is preset for the 20% standard rate.
8. Can this calculator be used for different VAT rates, like the 5% reduced rate?
While this tool is primarily designed as a 20% VAT calculator for the standard rate, you can manually calculate other rates. To add 5% VAT, multiply your net amount by 1.05. To remove 5% VAT, divide your gross amount by 1.05. Always ensure you are using the correct rate for the specific goods or services in question.
