Greeting DAPPS Lovers! Learn How to Calculate Interest Rates with Ease
Do you ever wonder how banks calculate interest rates? Are you planning to get a loan? Do you want to know if the interest rate offered is reasonable? Understanding how to calculate interest rate is essential in making informed decisions about finances. In this article, we will guide you on how to calculate interest rate and its strengths and weaknesses. Let’s get started!
What is Interest Rate?
Interest rate is a percentage of the borrowed principal amount. It is the amount charged by the lender for the borrowed amount. Interest rate can be simple or compounded. Simple interest rate only applies to the borrowed principal amount while compounded interest rate applies to both the principal amount and the interest that has accumulated.
👉Tip: Interest rate is expressed as a percentage.
The Formula for Calculating Simple Interest Rate
Calculating simple interest rate is easy. You just have to multiply the principal amount by the interest rate and the time of the loan. The formula for calculating simple interest rate is:
| Formula for Simple Interest Rate |
|---|
| Interest = Principal x Rate x Time |
👉 Example: If you borrowed $10,000, with an interest rate of 5% for five years. The calculation will be:
| Calculation for Simple Interest Rate |
|---|
| Interest = $10,000 x 5% x 5 |
| Interest = $2,500 |
The Formula for Calculating Compounded Interest Rate
Compounded interest rate is a little bit more complicated. It involves calculating the interest that has accumulated on top of the borrowed principal amount. It is also called the future value of the loan. The formula for calculating compounded interest rate is:
| Formula for Compounded Interest Rate |
|---|
| Future Value = Principal x (1 + Rate)^Time |
👉 Example: If you borrowed $10,000, with a compounded interest rate of 5% for five years. The calculation will be:
| Calculation for Compounded Interest Rate |
|---|
| Future Value = $10,000 x (1 + 5%)^5 |
| Future Value = $12,763.25 |
