Track your TreasuryDirect I Bonds and EE Bonds from your phone — estimated values, interest earned, penalty-free dates, and rate resets.
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
