Annual Rate Calculator
What Is an Annual Rate Calculator?
An Annual Rate Calculator is a financial tool designed to calculate how much your initial investment (principal) will grow over a certain number of years at a given annual interest rate.
The calculator applies the compound interest formula: A=P×(1+r100)tA = P \times (1 + \frac{r}{100})^tA=P×(1+100r)t
Where:
- A = Final amount (Principal + Interest)
- P = Principal amount (initial investment)
- r = Annual interest rate (in %)
- t = Time period in years
This formula ensures accurate calculation of both the total amount and the interest earned.

Example Calculation
Let’s take an example to see how this works:
- Principal Amount (P): $1,000
- Annual Interest Rate (r): 5%
- Time Period (t): 10 years
Using the formula: A=1000×(1+5100)10A = 1000 \times (1 + \frac{5}{100})^{10}A=1000×(1+1005)10 A=1000×(1.05)10A = 1000 \times (1.05)^{10}A=1000×(1.05)10 A=1628.89A = 1628.89A=1628.89
- Total Amount = $1628.89
- Interest Earned = $628.89
This means if you invest $1,000 at 5% interest for 10 years, you’ll have a total of $1628.89, with $628.89 earned as profit.
