You can save your inventory so you can update your bond values quickly and easily. All you need to do is use your browser's built-in saving function. Click “View/Print/Save List” 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 that you know where on your computer’s hard drive it will be saved. Then click "Save". You've saved your file! If you'd like more detail, check out our Instructions for Saving Your Inventory Page. NOTE: You must follow these steps when re-saving an inventory you’ve updated.
You can open your existing inventory (if you have one) by navigating to the folder or directory where you saved your list using a file management program such "My Computer" (for Windows users) or the "Finder" (for Mac OS users). Once you locate your file, double-click it. This should load the file into your web browser where you can click the "Return to Savings Bond Calculator" button to update the values and continue working with your inventory.
You must follow the instructions for saving your inventory (above) once you’ve updated the values or added or removed bonds. If you'd like more detail, check out our Instructions for Saving Your Inventory Page.
If you choose to report interest to the IRS annually, check out the Calculator's YTD Interest feature. It reports the amount of interest your 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 bonds accrued in one calendar year:
- List the 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 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 bonds accrued that year.
