Simple Interest: Yearly and Monthly Accumulations
Simple interest is the amount of interest paid or earned on an amount of money over a period of time, without considering the compounding effect.
Yearly Interest Calculation:
Calculate the yearly interest by multiplying the principal amount (the initial amount of money) by the interest rate.
For example, if the principal amount is 5.
Monthly Interest Calculation:
Divide the yearly interest by 12 to get the monthly interest.
This is because interest is calculated on a monthly basis, regardless of the number of days in a month.
For example, if the yearly interest is 0.4167.
Examples:
Yearly Interest:
If you invest 105, with an annual interest of $5.
If you invest the same amount in a savings account with an interest rate of 2%, the total amount after one year would be 2.
Monthly Interest:
If you invest 10.25, with a monthly interest of $0.25.
If you invest the same amount in a savings account with an interest rate of 2%, the total monthly amount after one month would be 0.10.
Key Points:
Simple interest is calculated on the principal amount only, not on the interest earned or paid.
Interest is calculated on a yearly basis for annual interest and monthly basis for monthly interest.
The amount of interest earned or paid over time is directly proportional to the principal amount and the interest rate
