I have several EE series US savings bonds which I would like to cash, they were all given to me on the same date in different years, and I calculated the interest online, the calculator said that based on the info I provided the accrual date was in one month.
Does this mean that I should wait one more month to accrue one more set of interest before cashing the bonds, or is the interest added in such a way that it does not matter when I cash them?
