GST rates vary by country and product, typically ranging from 5% to 18% or more, often calculated as 15% in regions like New Zealand. To calculate it, multiply the net price by the GST rate percentage. If the price includes GST, divide the total by 11 to find the GST amount (e.g., in Australia).
To calculate GST you'll need to know which GST slab the product fits into. The GST slabs are currently set at 5%, 12%, 18% and 28% for most goods and services. To calculate IGST, just multiply the taxable amount by the appropriate GST rate. For an intra-state transaction, you'll need to calculate CGST & SGST/UTGST.
GST is a broad-based tax of 10% on most goods, services and other items sold or consumed in Australia. To work out the cost of an item including GST, multiply the amount exclusive of GST by 1.1. To work out the GST component, divide the GST inclusive cost by 11.
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.
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.
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. The answer will be your GST component.

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).
There are different slabs for GST i.e. 5%, 12%, 18% and 28%. For instance, if a goods or services is sold at Rs. 1,000 and the GST rate applicable is 12%, then the net price calculated will be = 1,000+ (1,000X(12/100)) = 1,000+120 = Rs. 1,120.
The tax is a 5% tax imposed on the supply of goods and services that are purchased in Canada, except certain items that are either "exempt" or "zero-rated": For tax-free — i.e., "zero-rated" — sales, GST is charged by suppliers at a rate of 0% so effectively there is no GST collected.
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.

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.

When must I collect GST/HST? If your business earns more than $30,000 in gross income (what you earn before you deduct business expenses) during any 12-month period, you must get a GST/HST number and collect GST/HST from your customers.

A. Planning for GST to Save on GST
The goods and services tax/harmonized sales tax (GST/HST) credit is a tax-free quarterly payment for individuals and families with low and modest incomes to help offset the GST or HST they pay. It may also include payments from provincial and territorial programs.
For a $70,000 income in Canada (using 2025 rates), you'll pay roughly $13,000 to $20,000 in total taxes (federal, provincial, CPP, EI), depending on your province, resulting in a take-home pay around $50,000-$59,000, with federal tax around 14.5% or 20.5% depending on the portion, plus provincial tax and deductions like CPP and EI.
Key Changes at a Glance: New GST Rates
This means that the messy middle ground, the 12% and 28% slabs, is gone. Products once taxed at those rates will now either slide down to 5% or 18%, or move up to 40% depending on their category.
Common mistakes include issues such as claiming GST on private purchases or failing to use the correct tax codes. By understanding these pitfalls, businesses can refine their record-keeping habits and ensure that they meet their tax obligations effectively.
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.
Calculation: Base Price: ₹50,000. GST Amount: ₹50,000 × 18% = ₹9,000. Total Amount: ₹50,000 + ₹9,000 = ₹59,000.
