How to calculate GST on sales and purchases?

When it comes to taxes, GST (Goods and Services Tax) is one of the most important ones businesses need to understand. Whether you are selling products, buying materials, or even just starting a business, knowing how to calculate GST on sales and purchases is essential. But don’t worry, we’re here to break it down step by step in a simple and fun way, so you can tackle it like a pro!

What is GST and Why Does It Matter?

Before we dive into the nitty-gritty of calculations, let’s start with the basics. GST is a tax applied on the supply of goods and services. It’s a value-added tax that helps the government collect revenue. The beauty of GST is that it’s applied at every stage of the supply chain, from manufacturers to the end consumer.

Think of it like a relay race—each runner (or business) adds value to the product, and at each stage, GST is collected. The tax amount depends on the rate applicable to the product or service, which can vary based on the industry, product type, and even the location.

How to calculate GST on sales and purchases?: Step-by-Step

Now that you have a clear picture of what GST is, let’s talk about how to calculate GST on sales. This is when you sell goods or services to your customers.

1. Know the GST Rate for Your Product

First things first: you need to know the GST rate applicable to your product or service. GST rates in India, for example, can be 5%, 12%, 18%, or 28%. You can find the rate specific to your goods on the government’s GST website or consult with a tax professional.

If you’re in another country, make sure to check the applicable GST rate in your region.

2. Use the Formula to Calculate GST on Sales

The formula to calculate GST on sales is super simple:

GST on Sales = (Selling Price x GST Rate) / 100

Let’s break that down:

  • Selling Price: The amount you are selling the product for.

  • GST Rate: The applicable GST rate (like 5%, 12%, 18%, or 28%).

Example:

You are selling a T-shirt for ₹500, and the GST rate is 18%. Here’s how to calculate:

GST on Sales = (500 x 18) / 100 = ₹90

So, the GST you need to collect from the customer is ₹90. The total price they will pay is ₹590 (₹500 + ₹90).

3. Add GST to Your Selling Price

If you want the customer to pay the selling price + GST, you’ll add the GST amount to the selling price. In this case, the total cost will be ₹590 (₹500 + ₹90).

If you want to include GST in the price and show the GST portion separately, you need to use the reverse calculation method, which we’ll talk about next.

How to Calculate GST on Purchases: Step-by-Step

When you’re buying goods or services for your business, you also pay GST. But, the good news is that you can reclaim the GST you’ve paid on purchases by using Input Tax Credit (ITC). This helps you avoid paying double tax, making the system more efficient.

1. Find the GST Rate for Your Purchase

Just like with sales, you need to know the GST rate on the goods or services you’re purchasing. If you’re buying raw materials, services, or anything else for your business, check the GST rate for that specific product.

2. Use the Formula to Calculate GST on Purchases

The formula to calculate GST on purchases is pretty similar to sales:

GST on Purchases = (Purchase Price x GST Rate) / 100

Example:

Let’s say you buy materials for your business worth ₹1,000, and the GST rate is 12%. Here’s how to calculate:

GST on Purchases = (1,000 x 12) / 100 = ₹120

So, you paid ₹120 as GST for that purchase.

3. Claim Input Tax Credit (ITC)

Once you’ve calculated the GST on your purchase, you can claim that amount back. This is known as Input Tax Credit (ITC). ITC is the credit you get for the GST you paid on your business-related purchases. You can use it to offset the GST you collect from your customers.

Let’s say you collected ₹90 GST on sales and paid ₹120 GST on purchases. You can offset the ₹90 GST you collected from customers against the ₹120 GST you paid for purchases. This means you only need to pay ₹30 (₹120 – ₹90) to the government.

Example: How to Calculate GST on Sales and Purchases Together

Let’s put it all together with a real-life example to make things clearer.

Scenario:

  • You sell a product for ₹1,000, and the GST rate is 18%. You collected ₹180 as GST from the customer (1,000 x 18%).

  • You purchased materials worth ₹600, and the GST rate is 18%. You paid ₹108 GST on that (600 x 18%).

GST on Sales = ₹180
GST on Purchases = ₹108
Input Tax Credit (ITC) = ₹108

So, you’ll pay the government:

GST to be paid = GST on Sales – ITC = ₹180 – ₹108 = ₹72

This means you need to pay ₹72 as GST to the government after using your Input Tax Credit.

Common Mistakes to Avoid When calculate GST on sales and purchases?

While calculating GST may seem straightforward, there are a few common mistakes businesses often make. Let’s take a look at them so you can avoid them like a pro!

1. Forgetting to Include GST in the Selling Price

Some businesses forget to add GST when setting their prices, which can lead to confusion or loss of revenue. Always double-check that you’re adding the correct GST amount to the final price when selling to customers.

2. Not Claiming Input Tax Credit

Another mistake is not claiming Input Tax Credit (ITC) on purchases. Always remember that you can recover the GST you paid on business-related purchases. Don’t let that money slip away!

3. Using Incorrect GST Rates

Different products and services have different GST rates. Using the wrong rate can lead to incorrect calculations and potential fines. Be sure to check the rate before calculating.

4. Not Keeping Track of Transactions Properly

Keeping accurate records of all your sales and purchases is key. If you don’t track your GST payments and collections, it can be tough to calculate your liabilities and claim your credits. Use an accounting software or spreadsheet to stay organized.

Final Thoughts: calculate GST on sales and purchases?

Calculating GST on sales and purchases might seem like a complicated process, but once you break it down step by step, it’s really just a matter of applying the right formulas and keeping accurate records. Whether you’re a small business owner or a seasoned pro, understanding how GST works is crucial for your business’s success.

Now that you know how to calculate GST on both sales and purchases, you can confidently tackle your tax responsibilities and ensure your business runs smoothly. Just remember: always stay updated on GST rates, claim your Input Tax Credit, and keep your transactions neat and tidy.
