I Bonds: Here’s a simple way to track current value (2024)

TreasuryDirect’s information often confuses investors. There is another way.

By David Enna, Tipswatch.com

Almost every week, I get questions about the way TreasuryDirect shows the current value of I Bonds purchased within the last five years. Here are recent examples:

“I-Bond was purchased last April. So far … the actual annual earning rate is not 7.12% as we saw last April but low. Is it because the current holding has not included the last 3 month interest? Can you explain it? Thank you.”
… “I invested $10,000 on 6/13/22 and I only gained $156 in value on 11/1/22. That seems low given that the interest rate was 9.62%. Help!”

I Bonds: Here’s a simple way to track current value (1)

The usual advice. You can check the total value of your Series I Savings Bonds after logging into TreasuryDirect’s account pages and then clicking through to the totals for the individual bonds. Or you can use the Treasury’s Savings Bond Calculator, which TreasuryDirect claims is only for paper I Bonds (maximum amount of $5,000 each) and isn’t accurate for electronic I Bonds. But it is accurate for electronic bonds, you just have to double the $5,000 amounts for purchases of $10,000 in that form.

I wrote a step-by-step guide to using the Savings Bond Calculator back in June 2018, and I think the basics remain just about the same. One of the advantages of using the calculator is that it creates a browser-based file you store on your computer. It can be updated without actually logging in to TreasuryDirect, and then saved again.

Eyebonds.info: A valuable resource

If you want to track the current value of your I Bond investment, Eyebonds.info is an excellent and reliable site. It’s a creation of Bob Hinkley, a retired corporate financial analyst and computer programmer (and famed Boglehead contributor). It’s very simple to use:

Go to the homepage.
Click on I Bonds.
Find the month you purchased the I Bond in the table and click on it.
Click on the investment amount listed below that matches your original investment.

The page that then displays the earned-interest history of your I Bond, all the way to the end of the your current composite rate (the end month depends on the month you purchased the I Bond). The numbers presented do not subtract the last three months of interest, so remember if you redeem early, you will lose those three months of interest.

Now, let’s run through some examples. In these examples, I am presenting results for a $10,000 investment in April of various years. The top section of each chart shows the Savings Bond Calculator’s presentation (doubled to match the $10,000 investment). The bottom section of each example comes from Eyebonds.info.

Example 1 is for a $10,000 I Bond purchased in April 2022. TreasuryDirect shows a value of $10,436, but that does not include the last three months of interest. The Eyebonds.info presentation shows a current value (as of Feb. 1, 2023) of $10,684 and continues with interest calculations through October 1. Note that the Eyebonds.info information for Nov. 1, 2022, matches TreasuryDirect’s calcuation, because it does not include interest for November, December and January.

Also, note that I Bonds earn interest for the previous month on the first day of each month. Don’t get confused by that. You don’t earn interest until the month is completed.

TreasuryDirect’s reasoning

By eliminating (hiding, actually) the last three months of interest for I Bonds held less than 5 years, TreasuryDirect is attempting to cause less confusion, not more confusion. If it showed the full total, and investors redeemed early, they would swamp TreasuryDirect with complaints they were cheated. So TreasuryDirect focuses on presenting an accurate current redemption value, not current total value.

I’ve suggested that TreasuryDirect simply create two columns, one for redemption value and one for current value. That would really lessen investor confusion. But … that’s not happening.

Anyway, Eyebonds.info is a tremendous resource for tracking and understanding the current and near-future value of your I Bonds. It also has historical information on TIPS, and a treasure-chest of information on U.S. inflation dating back to 1971.

The site also has an Excel-based I Bond Calculator you can download. I haven’t used it, but a lot of my readers seem passionate enough (and nerdy enough?) to give it a try. Let me know how it works. For me, the Savings Bond Calculator and Eyebonds.info are all I really need.
