- Analyzing financial documents like electricity bills.
- Calculating electricity consumption and costs.
- Understanding and calculating VAT.
- Applying tariff systems to calculate total costs.
Introduction to Financial Documents
The lesson focuses on financial documents, particularly household bills like electricity bills. Students should be able to analyze financial documents related to personal and household finances, workplace and small business finances, and complex financial topics like tax forms and loan documentations. The goal is to interpret information from these documents to answer related questions. The video will specifically address household bills, focusing on electricity bills, and will later cover tariff systems.
Analyzing an Electricity Bill
The video analyzes an electricity bill issued by the Bombella Municipality to Mr. Esfaniarden. The bill includes details such as the municipality's address and contact information, Mr. Esfaniarden's address, the invoice number, and the date of issue (29th of November 2016). It also provides consumption details, including the units reflecting at the beginning (114,628 kWh) and end of the month (115,353 kWh). The tariff is 0.219 Rands per kilowatt-hour used, and the subtotal before VAT is 158.78 Rands. The total amount due, including VAT, is also provided.
Calculating Electricity Usage and VAT
To determine how many kilowatt-hours Mr. Esfaniarden used in November, subtract the previous reading (114,628 kWh) from the current reading (115,353 kWh), resulting in 725 kWh. VAT, or value-added tax, is 14% of the subtotal. To calculate the VAT amount, find 14% of 158.78 Rands, which is 22.23 Rands. This can also be found by subtracting the subtotal from the total due (181.01 - 158.78 = 22.23).
Calculating the Subtotal Charge
The subtotal charge of 158.78 Rands is calculated by multiplying the number of units used by the tariff. The total cost is the number of units used (725 kWh) multiplied by the tariff (0.219 Rands per kWh), which equals 158.78 Rands. Alternatively, multiply the units (725 kWh) by the cost (0.219 Rands) and divide by one kilowatt-hour to ensure the units cancel out, leaving the total cost in Rands.
Calculating Costs for Different Usage
If Mr. Esfaniarden used 803 kWh in the previous month, assuming the tariff remains the same (0.219 Rands per kWh), the subtotal is calculated by multiplying 803 kWh by 0.219 Rands per kWh, resulting in 175.86 Rands. To calculate the VAT, find 14% of 175.86 Rands, which is 24.62 Rands. The total amount due, including VAT, is 175.86 Rands plus 24.62 Rands, totaling 200.48 Rands.
