3. Formula
To understand how the Interest Rate Calculator works, it is essential to know the basic formula for calculating interest:
- Simple Interest Formula:
I = P × r × t
Where:- I = Interest
- P = Principal amount (initial investment or loan)
- r = Annual interest rate (as a decimal)
- t = Time (in years)
- Compound Interest Formula:
A = P(1 + r/n)^(nt)
Where:- A = the future value of the investment/loan, including interest
- P = the principal investment amount
- r = annual interest rate (decimal)
- n = number of times that interest is compounded per year
- t = the number of years the money is invested or borrowed
4. Example Calculation
Let’s say you take a loan of $10,000 at an annual interest rate of 5% compounded annually for 3 years. Using the Compound Interest Formula, you can calculate:
- P = $10,000
- r = 0.05
- n = 1 (compounded annually)
- t = 3
Plugging into the formula:
A = 10,000(1 + 0.05/1)^(1*3) = 10,000(1.05)^3 = 10,000 * 1.157625 = $11,576.25
Total interest earned on this loan would be $11,576.25 – $10,000 = $1,576.25.
5. Limitations
While the Interest Rate Calculator is a powerful tool, it has its limitations:
- Availability of Accurate Data: If the interest rates provided are outdated or incorrect, the calculation will yield inaccurate results.
- Exclusion of Fees: Most calculators do not factor in additional fees or terms that may come with loans or savings accounts.
