Frequently Asked Questions

A GST calculator is a tool that helps you calculate either the GST-inclusive or GST-exclusive price of goods and services. It works by applying the standard GST rate to your net amount, showing exactly how much tax is added.

Multiply the net price by 1.18 (for 18% GST) to get the gross price. To find only the GST amount, multiply by 0.18. To remove GST, divide the gross price by 1.18.

The formula is: Net Amount × 1.18 = Gross Amount. Alternatively, Net Amount + (Net Amount × (18/100)) = Gross Amount.

Inclusive: Divide the total amount by (1 + GST rate). Exclusive: Multiply the net amount by (1 + GST rate).

Divide the total gross amount by 1 plus the tax rate (e.g., divide by 1.18 for 18% tax) to find the original net amount.

Simply multiply the base amount by 1.18 to get the total including GST.

A reverse GST calculator works backwards from a total price (inclusive of tax) to determine the original pre-tax amount and the exact tax paid.

Enter the net price, press the multiplication (×) key, enter the GST rate (e.g., 18), and press the percent (%) key or manually multiply by 1.18.

Multiply your starting amount by 1.12 to add the tax, or divide by 1.12 to remove the tax from a total price.

Enter your net amount, hit multiply (×), and type 1.20 (for 20% VAT) to get the final total.

Multiply the original price by 1.20 to find the total inclusive of 20% VAT.

VAT Amount = Net Price × (VAT Rate / 100). Gross Price = Net Price + VAT Amount.

Divide the gross inclusive amount by 1.20 to reveal the original base price before tax.

Usually, you hold the TAX+ or RATE button to enter tax mode, type the rate (e.g., 20), and press SET or TAX+ again to save it.

Simply multiply your service or product base price by 1.05 to get the total invoice value including UAE's 5% VAT.

The standard VAT rate in the UK remains at 20% for most goods and services in 2026, with reduced rates of 5% and 0% for specific categories.

Enter the final invoice total into the Gross field, select the country rate, and the calculator automatically deducts the VAT to show the Net Service value.

If the VAT is 20%, divide the total paid by 6 to find the exact VAT amount included in the price.

Multiply the base number by 1.12 to find the total price inclusively.

Depending on the tax rate, multiply the base amount by 1 plus the rate as a decimal (e.g., 1.15 for 15% tax).

Always apply the discount to the Net Amount first, then calculate the sales tax on the newly discounted subtotal.

First, apply your target profit margin to the base cost to find the Net Price, then add the VAT rate to establish the final retail Gross Price.

Determine the tax rate (e.g., 15%), add 1 to it as a decimal (1.15), and divide the total amount by this number.

Import VAT is calculated on the total value of the goods, PLUS the shipping cost, PLUS any import duties applied at customs.

An inclusive tax calculator takes a final retail price and breaks it down to show both the base cost and the embedded tax amount.
