How to Calculate the Interest on a US Savings Bond at Maturity
U.S. savings bonds are not investments with specific percentage interest rates. Rather, they are set in denominations and mature at specific points in time, at which point they can be redeemed for cash.
With the help of online calculators, there are ways to determine the amount of interest yielded by savings bonds. By determining what the final value of a bond will be upon maturing, the interest rate can be calculated manually.
The process, with the help of an online calculator, takes about 5 minutes.
