Using the Savings Bond Calculator: Values, Inventories, and Limits
The Treasury's savings bond calculator estimates values for eligible paper bonds using information such as series, denomination, and issue date. It is a valuation tool, not a record proving that a bond exists or that you own it. This guide explains how to enter bonds, build an inventory, and interpret the calculator's limits. It helps owners organize old paper holdings without mistaking a saved calculation for a replacement bond or a redemption request.

Value today
Value on past dates
Value on future dates through the current six-month interest period
Current and past interest rates
Next accrual date
Maturity date
Total interest earned
Year-to-date interest earned
Current Value
To find the current value of a bond, enter its series, denomination, and issue date, then click "Calculate." (You need not enter the bond’s serial number. But if you’re building an inventory, serial numbers might help you distinguish one bond from another in your list.)
To see where the issue date and serial number are found on a bond, see our diagram.
Past or Future Value
To find the value of a bond on a past or future date, enter the date in the "Value as of" field; enter the bond’s series, denomination, and issue date; then click "Update." (Past values are available back to January 1996. Future values are available for remaining months in a bond’s current six-month rate period.)
Inventory of Bonds
You can create an inventory of paper bonds and check their values over and over in the future without re-entering information:
To create an inventory, enter information about your paper bonds, one bond at a time, into the Calculator.
To save an inventory for future use:
- Click the "Save" button in the results section of the Calculator. This creates a new page, your inventory page.
- Using your browser’s "Save As" function, save the new page as a web page or HTML page.
To use an inventory you created previously, open the inventory and click whichever one of these buttons you see: "Return to Savings Bond Calculator" or "Update." This automatically updates the values of the bonds in the inventory and enables you to add bonds to the inventory.

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).
Want to save your inventory?
Note: The Calculator won't save your inventory of paper bonds if you're using either of these browsers: Google Chrome, Microsoft Edge.
You can save your inventory so you can update your paper bond values quickly and easily. All you need to do is use your browser's built-in saving function. Click the "Save" button in the results area and then when the list appears, click "File" and 'Save As' and name your inventory. Make sure that you save your file as an "HTML Only" file and click 'Save.' If you'd like more detail, check out our Instructions for Saving Your Inventory Page.
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.
Putting this into practice
Compare every entry with the actual bond and save an independent inventory of identifying details. Check the valuation date before relying on a displayed amount. If ownership, loss, or redemption is the issue, use the relevant Treasury process rather than expecting the calculator to resolve it.
