Saving Bond Calculator
hat is a Saving Bond Calculator?
A Saving Bond Calculator is an online financial tool that helps investors estimate the future value of their savings bonds. By entering three simple inputs — principal amount, interest rate, and time period — you can instantly see:
- The total value of your bond after the selected number of years.
- The interest earned during the investment period.
This tool uses the compound interest formula, which accounts for how money grows when interest is added back into the principal over time.
Formula used: Total Value=P×(1+r100)t\text{Total Value} = P \times (1 + \frac{r}{100})^tTotal Value=P×(1+100r)t
Where:
- PPP = Principal Amount
- rrr = Annual Interest Rate (%)
- ttt = Time in Years
