Math Chapter 8: An Overview of Compound Interest

Compound interest can be worked out by adding up the principal and the interest that has been earned over time. It’s different from simple interest because the interest doesn’t get added to the principal when the interest for the next period is calculated. In math, C.I. is often used as a shorthand for compound interest. Compound interest is a term used in math to talk about how interest builds up over time.

Different situations call for different ways to figure out how to calculate compound interest. We can use the formula for compound interest to make math easier. To figure out the interest on the interest, we need to know the amount and the principal. It’s the difference between how much you owe and how much you owe in total.

Compound Interest

Compound interest is calculated in a similar way to simple interest since the principal (the amount on which interest is calculated) is renewed every year. Once you put money in a bank, you will get interested in it every year. This doesn’t stay the same from year to year, but it does go up. For example, to figure out the interest on Rs 1000 over two years at a rate of 10% per year, we must add up the interest for each year.

Simple Interest

It is a quick way to figure out how much you still owe on a loan. Simple interest is a concept that is used in many different fields, such as banking, finance, and cars. When you pay back a loan, the interest is taken out first, and then the rest goes to the principal. In this post, we will look at the definition, the simple interest formula, and how to figure out simple interest.

Important Formulae

Compound Interest = Amount – Principal

• If we know the Selling Price of an item and profit from selling it, then,
• Cost Price = Selling Price – profit
• If we have the Selling Price of an article and loss on its selling then,
• Cost Price = Selling Price + Loss

Computing the Selling Price

If you know the item’s Cost Price and how much profit when it was sold, you can figure out its Selling Price by adding its Cost Price and its profit.

• Selling Price = Cost Price + Profit
• If we have the Cost Price of an article and loss on its selling then,
• Selling Price = Cost Price – Loss

What is a profit and what is a loss?

Profit is simply the extra money a business owner makes when the selling price is higher than the cost price.

• When S.P > C. P
• S.P – C.P = Profit
• When someone sells an item for less than what they bought it for or what it cost them, they have made a loss.
• When C.P > S.P
• C.P – S.P = Loss

How to Figure Out the Profit Percentage

The formula makes it easy to figure out the percentage of profit.

• Profit % = (Profit/C.P x 100)%
• Selling Price = (100 + Profit%) / 100 × CP
• Cost Price = 100/ (100 + gain %) × Cost Price

Getting the percentage of loss

The formulas below make it easy to figure out the loss percentage:

• Loss % = (loss/ CP × 100)%
• Selling Price = (100 – loss %) /100 × CP
• Cost Price = 100 /(100 – loss %) × SP

How to figure out Value-Added Tax (VAT)

The government must be paid VAT = (Output VAT- Input VAT)

Output VAT means the tax that is paid when goods are sold. The output VAT is added to the price of the goods when they are sold.

Input VAT = The tax you pay when you buy something is what Input VAT stands for. The cost price of the goods is used to figure out how much VAT is due.
