Goods and Services Tax (GST)

Welcome, everyone! Today, we're diving into Goods and Services Tax, commonly known as GST. To start, does anyone know what GST is?
Isn't it a type of tax on goods and services?
Exactly! GST is an indirect tax levied on the supply of goods and services. Can you name the different components of GST?
Isn't there CGST and SGST?
Right! CGST stands for Central GST and SGST means State GST. They make up the total GST for transactions occurring within a state, each being 50% of the total. What if the transaction is between states?
Then it's IGST?
Correct! IGST is Integrated GST. Let's try a simple calculation. If a shopkeeper buys goods worth ₹10,000 at 18% GST, how much is the input GST?
It's ₹1,800!
Perfect! Now, if they sell it for ₹15,000, can someone calculate the output GST?
That's ₹2,700!
Excellent! Now, what about the net GST payable?
That would be ₹900!
Great work! Remember to calculate like this: Net GST Payable = Output GST – Input GST. Let's summarize what we discussed: GST is an indirect tax with CGST and SGST as major components for in-state transactions, while IGST is for inter-state transactions.

Moving on to banking! Today, we focus on Recurring Deposit Accounts. Who can explain what an RD is?
It's a savings account where you deposit a fixed amount every month!
Exactly! And it helps in saving money steadily. How do we calculate the interest for an RD?
With that formula that uses P, n, and r?
Yes! The formula is I = P × n(n+1) × r / 2 × 12 × 100. Can someone tell me what each symbol represents?
P is the monthly deposit, n is the number of months, and r is the annual rate.
Correct! If a student deposits ₹1,000 for 12 months at an 8% annual interest rate, what would the interest be?
That would be ₹520!
Right! Finally, how would you calculate the maturity value?
It’s the total amount deposited plus interest, so ₹12,520!
Exactly! To wrap up, remember that an RD account is a disciplined way to save money with interest calculated on monthly deposits.
Shares and Dividends

Now, let’s talk about shares and dividends. Who can explain what a share is?
It’s a unit of ownership in a company, right?
Yes! Each share represents a fraction of the company's ownership. What are face value and market value?
Face value is the nominal value, and market value is what people pay for it in the market.
Exactly! Another important term is 'dividend.' Who can tell me what it means?
It’s the return paid to shareholders, usually a percentage of the face value.
Great! Let’s calculate a dividend. If a company announces a 12% dividend on a ₹100 share, how much is that?
That would be ₹12.
Correct! And if this share's market value is ₹120, what is the yield?
10%!
Fantastic! Remember: Yield% = (Dividend / Market Value) × 100. Let’s summarize: Shares represent ownership, dividends are returns on shares, and we can calculate yield using dividends and market values.

Detailed
Commercial Mathematics
This chapter introduces crucial principles of Commercial Mathematics, integrating real-life applications into mathematical concepts. The section is divided into three major topics:
1.1 Goods and Services Tax (GST)
GST, an indirect tax applied on the supply of goods and services, is explained along with its components such as CGST, SGST, and IGST. Key formulas are provided to help calculate GST implications in practical scenarios. Examples highlight how GST impacts both buyers and sellers, fostering better understanding of tax calculation.
1.2 Banking
This section explains the concept of Recurring Deposit Accounts (RDs) that allow individuals to save by depositing a fixed amount regularly. The interest and maturity value calculations are illustrated with a practical example, emphasizing the benefits of disciplined saving.
1.3 Shares and Dividends
The final component delves into the basics of shares and dividends, clarifying their significance in the market economy. Understanding face value, market value, and yield percentage equips students with the ability to make informed investment choices. Example calculations reinforce the application of dividends and share values in real scenarios. Overall, this chapter equips students with essential mathematical skills for navigating the commercial landscape.

GST: An indirect tax levied on the supply of goods and services.
CGST and SGST: Central GST and State GST – each charged at 50% of the total GST when goods/services are sold within a state.
IGST: Integrated GST – charged on inter-state supply.
Detailed Explanation
Goods and Services Tax (GST) is an indirect tax that applies to the supply of goods and services. It means that when you purchase an item or get a service, a certain percentage of the price is added as tax. This tax is collected by the government. In India, there are different types of GST:
- CGST (Central Goods and Services Tax) and SGST (State Goods and Services Tax) are levied when transactions occur within a single state. They are split evenly, so each takes 50% of the total GST applied.
- IGST (Integrated Goods and Services Tax) is applied when goods or services are sold between different states, ensuring that the tax is correctly allocated between the central and state governments.
Examples & Analogies
Consider when you go to a restaurant and order food worth ₹1,000. The restaurant will charge you GST on top of this amount. If the total GST is 18%, you will actually pay ₹1,180 because ₹180 is the GST collected. This illustrates how GST is applied in everyday transactions.

Formulas
- GST = Taxable Amount × GST Rate
- Final Price = Cost Price + GST
- Input Tax Credit (ITC): Credit received for tax paid on purchases.
- Net GST Payable = Output GST – Input GST
Detailed Explanation
There are several important formulas related to GST that help determine the tax amount and the final price of goods and services:
- GST = Taxable Amount × GST Rate: This formula helps you calculate how much GST you need to pay based on the taxable amount of goods/services you are purchasing and the rate of GST that applies.
- Final Price = Cost Price + GST: After calculating GST, you can find out the final price you need to pay by adding the GST to the original cost.
- Input Tax Credit (ITC) allows businesses to reduce the tax they have to pay based on the tax they have already paid on their purchases.
- Net GST Payable helps determine how much GST a business has to pay to the government, taking into account the GST they have collected from sales (Output GST) minus the GST they have paid on purchases (Input GST).
Examples & Analogies
If you buy a dress for ₹2,000 with an 18% GST:
- GST = ₹2,000 × 18% = ₹360.
- Therefore, the final price you would pay is ₹2,000 + ₹360 = ₹2,360. If you later sell that dress for ₹2,500 and collect 18% GST, you can use the input credit to pay the difference in tax amount. This way businesses are not double taxed on the same transaction.

Example
A shopkeeper buys goods worth ₹10,000 at 18% GST and sells them for ₹15,000.
- Input GST = ₹10,000 × 18% = ₹1,800
- Output GST = ₹15,000 × 18% = ₹2,700
- Net GST = ₹2,700 – ₹1,800 = ₹900
Detailed Explanation
Here's a practical example of how GST works:
- A shopkeeper purchases goods worth ₹10,000. At an 18% GST rate, the GST added is ₹1,800.
- Later, when the shopkeeper sells these goods for ₹15,000, the GST collected from the buyer is ₹2,700.
- To determine how much GST the shopkeeper needs to pay to the government, subtract the Input GST (the tax amount from the purchase) from the Output GST (the tax amount collected from the sale). So, the Net GST payable will be ₹900.
Examples & Analogies
Imagine you are running a small grocery store. You buy fruits costing ₹10,000, paying an additional ₹1,800 as GST. Later, you sell those fruits for ₹15,000. You collect ₹2,700 from your customer as GST. Before you pay taxes, you subtract what you already paid when you bought the fruits, making your final tax payment ₹900. This shows the flow of tax through buying and selling processes.
