Formula

The formulas used in the Interest Calculator depend on the type of interest you are calculating:

Simple Interest Formula:

SI = P * R * T

Where:

• SI: Simple Interest
• P: Principal amount
• R: Annual interest rate (in decimal)
• T: Time (in years)

Compound Interest Formula:

CI = P (1 + r/n)^(nt)

Where:

• CI: Compound Interest
• P: Principal amount
• r: Annual interest rate (in decimal)
• n: Number of times interest applied per time period
• t: Time in years

Example Calculation

Let’s say you invest $1,000 at a 5% annual interest rate for 3 years:

Simple Interest:

SI = 1000 * 0.05 * 3 = $150

Total Amount: $1,150

Compound Interest:

While the Interest Calculator is a valuable tool, it has some limitations:

• Fixed Inputs: The calculator assumes that inputs such as the interest rate and time are fixed, which may not reflect real-world scenarios.

• Tax Implications: Generated interest may be subject to taxes, which are not factored into the results.
