BondVault is a simple, on-device tracker for U.S. Treasury I Bonds and EE Bonds bought through TreasuryDirect.
TreasuryDirect has no mobile app and is hard to use on a phone. BondVault gives you a clean portfolio view of the savings bonds you already own. Enter each bond once — series, amount, and issue date — and BondVault estimates what it's worth today, how much interest it has earned, and when it crosses key milestones.
WHAT IT DOES
• Estimates current redemption value using the official Treasury composite-rate formula for I Bonds and the fixed-rate method for EE Bonds
• Shows accrued interest and your total portfolio value at a glance
• Flags the 3-month interest penalty that applies before 5 years, and shows each bond's penalty-free date
• Tracks the May and November rate-reset schedule and 30-year final maturity
• Projects future value so you can plan ahead
• Keeps your bond list on your device — no account or sign-up required
BONDVAULT PREMIUM (optional one-time unlock)
• Track unlimited bonds (free tracks up to 3)
• Full future-value projections
• Remove ads
IMPORTANT: BondVault is an independent, unofficial tool. It is not affiliated with, endorsed by, or connected to the U.S. Department of the Treasury, TreasuryDirect, or any government agency. Values shown are estimates calculated from published rate data and may differ from official figures. Always confirm balances and redemption values at TreasuryDirect.gov.
BondVault is free and supported by ads. Premium is a single purchase that unlocks everything forever — no subscription.
