Common questions
Is the calculator really free?
Yes. The bond calculator is completely free, requires no account, and works for both EE and I Bonds. Your bond details aren't even stored — everything runs in your browser.
How accurate are the values?
Our calculations are based on published Treasury Department formulas. They're estimates — for official valuations, visit TreasuryDirect.gov.
Can I cancel anytime?
Yes. Cancel your paid subscription at any time from your account settings. You keep access through the end of your billing period, then revert to the free calculator.
How do I redeem my bonds?
BondMinder doesn't handle redemptions. You can redeem electronic bonds via TreasuryDirect.gov or paper bonds at most banks. Consult your bank for details.
Are you affiliated with the Treasury?
No. BondMinder is an independent tool. We are not affiliated with, endorsed by, or connected to the US Department of the Treasury or TreasuryDirect.
My bond value seems wrong?
Double-check the purchase date and denomination you entered. If it still seems off, contact us with your bond details and we'll investigate. You can also verify against TreasuryDirect's calculator.
