To find the original price before tax, divide the total price (including tax) by 1 + tax rate 1 + t a x r a t e (in decimal form). Original Price = Total Price ( 1 + Tax Rate ) O r i g i n a l P r i c e = T o t a l P r i c e ( 1 + T a x R a t e )
To calculate the price before tax (reverse sales tax), divide the total price by (1 + the tax rate as a decimal); for example, if the total is $107 and the tax rate is 7% (0.07), you'd calculate $107 / 1.07 to get the $100 pre-tax price.
For example, if the cost of a product after GST of 18% is Rs. 118, its original cost is 118 – [100/(100 + 18%)}], which equates to Rs. 100.
To remove Value Added Tax or to make a reverse VAT calculation the formula is the following: Net: (Amount / 120) * 100 Easy! Divide the amount by 100 + VAT% and then multiply by 100. That's the amount excluding VAT taxes (Net amount).
How do I find the original price?
A Reverse Sales Tax Calculator is a tool that removes the sales tax portion from a total amount to reveal the original price before tax. Unlike a standard sales tax calculator that adds tax to a price, a reverse calculator works backward to separate the base price from the tax portion.
Therefore, our percentage is 20% and we can write . Step 2: Next, we must convert to a decimal. To do this, we divide by 100%. Step 3: Since we are dealing with a percent increase, we use the formula x = ( 1 + p ) x o to find the original value.
To do reverse percentages, find the original amount by first determining what percentage the given number represents (e.g., 100% - 20% discount = 80%), then divide the given number by that percentage to find 1%, and finally multiply by 100 to get the original total, or use the multiplier method: divide the final value by its decimal multiplier (e.g., 0.80 for an 80% value).
Reverse Charge Mechanism & Calculation
Reverse Sales Tax Calculations:
Price Before Tax = Total Price / (1 + Sales Tax Rate)
Where Total Price is the cell with the price inclusive of tax, and Sales Tax Rate is the cell with the tax rate expressed as a decimal. In Excel, you would input these formulas into the cells where you want to display the tax amount and the price before tax.
Subtracting GST:
To calculate how much GST is included in a price, just divide by 11. To calculate how much the price was before GST, just divide by 1.1. That's a lot of manual work for small-business owners to do every time they want o calculate GST—use our calculator instead.
Calculating reverse GST is important because it allows you to determine the GST-exclusive price from a GST-inclusive amount and arrive at an accurate tax amount.
Commonly used formulas include:
Step 1: Convert the percent discount to a decimal by dividing by . Step 2: Set up the equation P = ( 1 − d ) x to find the original price of the item where is the sale price, is the discount as a decimal, and is the original price of the item.

For example, if you have to work out the original price of a laptop that is being sold at 25% off:
Finding the Reverse Percentage of a number in 3 easy steps.
Step 1) Get the percentage of the original number. If the percentage is an increase then add it to 100, if it is a decrease then subtract it from 100. Step 3) Find 100% of the original number by multiplying the result from Step 2) by 100.
Answer: Reverse sales ' is the process of determining the pre-' amount from a total price that includes sales '. It is calculated by dividing the total amount by (1 + sales ' rate). For example, if the total amount is $107.50 and the sales ' rate is 7.5%, the pre-' amount is calculated as $107.50 / 1.075 ≈ $100.
