Not sure what data the Calculator is giving you?

If you have questions about any of the fields that are displayed, here are short descriptions of the fields displayed by the Calculator.

Bond Serial Number–The serial number can be found in the lower right corner of your paper savings bond. This information is not required, but is important for record-keeping purposes if your paper bonds are ever lost or destroyed.
‘Value as of’ Date–When you first open the Savings Bond Calculator, it shows what your paper bonds are worth today. If you want to see what they're worth in other months, you can change the 'Value as of' date. The Calculator can show what your paper bonds are worth in any month from January 1996 through the current rate period.
Series–The series can be found in the upper right corner of your paper savings bond. This Calculator provides values for paper savings bonds of these series: EE, I, E.
Denomination–The face value as shown in the upper left corner of your paper bond.
Issue Date–The date your paper bond was issued. It’s the month and year printed on the right side of your paper bond, below the series.
# Bonds–The number of paper bonds you’ve entered into this inventory.
Total Price–The total money you paid to buy the paper bonds in this inventory.
Total Interest–The combined amount of payable interest accumulated by the paper bonds listed in this inventory through the date listed in the ‘Value as of’ box.
Total Value–The combined cash value of the paper bonds listed in this inventory as of the date in the ‘Value as of’ box. This is what you’d receive if you cashed all of these paper bonds in that month.
YTD Interest– Year-to-Date interest. The total amount of interest accumulated by the paper bonds in this inventory from January of the year listed in the ‘Value as of’ box through the date given.
Issue Price–The money you paid to buy each paper bond in this inventory.
Interest–The amount of interest each paper bond has accumulated from its Issue Date through the ‘Value as of’ date.
Note: If a bond was issued May 1997 or later and it’s cashed before it’s five years old, it’s subject to a three-month interest penalty. The interest shown here incorporates this penalty.
Value–What each paper bond is worth as of the date given in the ‘Value as of’ field.
Interest Rate–The interest rate each bond is earning in the date listed in the ‘Value as of’ field. We use this rate to calculate the interest that accumulates on the Next Accrual Date.
Next Accrual–The first date after the date specified in the ‘Value as of’ box that each bond increases in value.
Final Maturity–The date each bond stops earning interest.
N/A–A bond’s current interest rate is not available. This means that
a) The bond has stopped earning interest;
or
b) We won’t know the rate the bond earns during the ‘Value as of’ date until the next rate period when new interest rates are announced;
or
c) The rate the bond earns can’t be retrieved from the database.
Note–Here are brief descriptions about special bond designations.
- NI. Not Issued–You changed the ‘ Value as of ’ date to a date before the paper bond was issued.
- NE. Not Eligible for Payment–Bonds with this designation can't be cashed until they are at least 12 months old.
- P5–Bonds issued May 1997 or later that are less than five years old include a three-month interest penalty.
- MA. Matured–This paper bond is matured and not earning interest. (used with "Value as of" dates for September 2004 and after).

Having problems loading your saved inventory file?

If you saved your inventory on the main Calculator screen and then attempt to reopen the file, you will get a page that has words on the left-hand side of the screen and you won’t immediately see your data.

Scroll down the page until you see an area that says “Calculate the Value of Your Paper Savings Bond(s).” In that area there’s an Update button. See the image below:

Be sure to click on the “How to Save Your Inventory” button before you resave your file to get complete instructions.

Do you report savings bond interest to the IRS every year as it accrues?

If you report interest annually, check out the Calculator's YTD Interest feature. It reports the amount of interest your paper bonds have accrued from the start of a year through the date you enter in the "Value as of" section. Here's how you can use this feature to calculate the amount of interest your paper bonds accrued in one calendar year:

List the paper bonds you want to report annually.
Enter December of the tax year in the 'Value as of' box. For example, if you want to find the interest your paper bonds accrued in 1999, enter "12/1999" in the 'Value as of' box.
Find the value in the 'YTD Interest' box. That's the amount of interest your paper bonds accrued that year.
