Compound Interest
What is compound interest?
Compound interest is the addition of interest to the principal sum of a loan or deposit, or the reinvestment of interest payments to the principal, so that the interest earned on the principal sum increases each year.
How does compound interest work?
The way compound interest works is that it takes the interest that has been earned and adds it to the original amount of the loan or deposit. This new total is then the new principal sum on which
S.I and C.I Formula Comparison:
The S.I and C.I formulas are two of the most commonly used formulas in physics. They are both used to calculate the force of a collision between two objects. However, they use different methods to calculate the force.
The S.I formula calculates the force as the product of the masses of the two objects and the square of the velocity of the objects just before the collision. The C.I formula calculates the force as the product of the masses of the two objects
Terms Related to Compound Interest
1. Principal: The initial amount of money invested in a compound interest investment.
2. Period: The length of time between investments in a compound interest investment.
3. Annual Percentage Rate (APR): The percentage of the principal that is charged as interest each year.
4. Future Value (FV): The amount of money that will be in a compound interest investment after a given number of periods, assuming that the investment is compounded at the given APR.
Calculations for Each Year:
In this essay, I will be calculating the average amount of rainfall each year for the past three years. I will also be calculating the average temperature each year for the past three years.
The average rainfall each year for the past three years is:
2013: 9.4 inches
2014: 10.3 inches
2015: 10.8 inches
The average temperature each year for the past three years is:
2013: 66.4 degrees
2014:
Compound Interest Half Yearly Formula:
The compound interest half yearly formula is a mathematical formula used to calculate the amount of compound interest that has accrued over a period of six months. The formula is as follows:
A = P(1 + r/2)^6
Where:
A = the amount of compound interest accrued
P = the initial principal amount
r = the annual interest rate
6 = the number of months
Compound Interest Examples:
1. Investing in a compound interest account
If you were to invest $1,000 in a compound interest account that earned 5% interest, after one year your investment would be worth $1,050. After two years, your investment would be worth $1,102.50. And after ten years, your investment would be worth $1,610.63.
2. Investing in a compound interest CD
If you were to invest $1,
Important Elements of calculating Compound Interest
There are four basic elements to compound interest: the principal, the interest rate, the number of periods, and the compounding frequency.
The principal is the amount of money that is being invested or borrowed. The interest rate is the percentage of the principal that is charged or earned as a fee for lending or borrowing the money. The number of periods is the number of times the interest is calculated over the life of the investment or loan. The compounding frequency is the number of times
Frequency of Compounding:
The rate at which an amount increases is determined by the periodicity with which interest is compounded : ”daily, monthly, or annually. Make sure you understand how often interest compounds whether you take out a loan or create a savings account.
If you borrow money, the quicker the interest compounds, the more your loan will cost.
Let’s say you borrow $1,000 at 10% interest compounded monthly. In the first month, you would owe $1,100. In the second month, you would owe $1,210, and so on.
If you save money, the slower the interest compounds, the more you will save.
Let’s say you save $1,
NCERT Study Material
National Council of Educational Research and Training (NCERT) is an autonomous organisation under the Union Ministry of Human Resource Development. It is responsible for designing and developing school textbooks and other educational materials for students from Classes I to XII. The textbooks are published in English, Hindi, Urdu and 21 other regional languages.
The NCERT study material is very good for students as it helps them understand the concepts in a better way. The textbooks are written in a simple language which makes it easy
