To check a GST calculator, verify that it correctly computes the tax amount using the formula: GST Amount = ( Original Cost × GST % ) / 100 G S T A m o u n t = ( O r i g i n a l C o s t × G S T % ) / 1 0 0 . Ensure it handles both exclusive prices (adding GST) and inclusive prices (removing GST) by calculating Net Price = Original Cost + GST Amount N e t P r i c e = O r i g i n a l C o s t + G S T A m o u n t .
The GST Calculator operates based on a straightforward formula: GST Amount = (Selling Price x GST Rate) / 100. Here, the Selling Price is determined by adding the Cost Price and Profit Amount.
To work out the cost including GST, you multiply the amount exclusive of GST by 1.1. You divide a GST inclusive cost by 11 to work out the GST component.
In this case, the sum of CGST and SGST/UTGST is equal to the total GST amount. Here's an example: If a product is sold at Rs. 1,000 and the GST rate applicable is 18%, then the net price calculated will be = 1,000+ (1,000X(18/100)) = 1,000+180 = Rs. 1,180.
The normal method for GST is subtracting the amount you paid on purchases (aka ITCs) from what you collected on your sales. This is the amount you must remit to CRA or if you paid more GST on your purchases than you collected on sales, CRA will send you a refund. Pretty simple except there are many rules you must know.
Subtracting GST from Price
To calculate how much GST was included in the price, divide the total price by 11 ($1000∕11=$90.91). To calculate the price without GST, divide the price by 1.1 ($1000∕1.1=$909.09).

The taxable estate is calculated as the value of the gross estate — the total, fair market value of all its assets — minus certain deductions, like the value of mortgages, debts, and any assets that go to a surviving spouse or qualified charity.
Calculation: Base Price: ₹50,000. GST Amount: ₹50,000 × 18% = ₹9,000. Total Amount: ₹50,000 + ₹9,000 = ₹59,000.
The formula for calculating GST is to multiply the net price (exclusive of GST) by 1.1 or divide the price including GST by 11 to determine the GST component.
Let's find out. If you have a GST-inclusive sales price and wish to calculate the 15% GST component of the total price, you can either divide it by 1.15 or follow this formula: Multiply the total sales price by 3. Divide the result by 23.

With the free GST calculator, you can calculate the tax amount in three simple steps. The tool provides you with three fields that have to be filled, and it calculates GST automatically based on what you fill in. Enter the price of the goods or services in the Amount field.
The value of a taxable supply is the consideration payable for the supply (before GST is added). For example, if the value of the supply is $100, the GST payable is 10 percent of $100, being $10. The price GST inclusive of the supply is $110. To work out the GST paid, you can divide by 11.
To calculate the amount of GST/HST to remit, multiply the revenue from your supplies (including the GST/HST) for the reporting period by the quick method remittance rate, or rates, that apply to your situation.
The different slabs for GST are 5%, 12%, 18% and 28%. GST calculation can be explained by a simple illustration : If a goods or services is sold at Rs. 1,000 and the GST rate applicable is 18%, then the net price calculated will be = 1,000+ (1,000X(18/100)) = 1,000+180 = Rs. 1,180.
