Terms of use
If you use this site, you agree to these terms.
For information only
The calculator provides information, not financial, tax or legal advice. The figures use Treasury's published rates and rules. For what your bonds are worth, TreasuryDirect is the official record. Look it over before you act.
This site isn't the U.S. Treasury
The site is independent. The U.S. Treasury, the Bureau of the Fiscal Service or TreasuryDirect don't run or endorse it, and it has no connection to them.
Projections
A new bond's growth figures assume today's rate holds steady. Real rates change every six months, so your actual results will be different.
Using the site
For personal use, you may use and share the results. Don't try to break, overload or make bulk copies of the site.
Liability
We provide the site as is. We aren't liable for losses caused by decisions based on it, within the limits the law sets.
