A simple tool to help bond holders not lose money
The US government doesn't remind you when your bonds stop earning. BondMinder does.
The problem we're solving
There are $28.1 billion in matured, unredeemed US savings bonds sitting in drawers and safety deposit boxes right now. These bonds stopped earning interest years ago, and the Treasury doesn't send reminders.
EE Bonds are guaranteed to double at exactly 20 years. If you redeem at 19 years and 11 months, you miss the doubling entirely. I Bond rates reset every 6 months based on inflation. When rates drop from 6% to 1.3%, nobody tells you.
BondMinder tracks these dates for you and sends you alerts so you never miss an important deadline.
How we operate
Privacy-first
We collect only what's needed to provide the service. Your bond data isn't sold to third parties. The free calculator doesn't even store your bonds on our servers — it runs in your browser.
Transparency
We're upfront about what we are (an informational tool) and what we're not (financial advisors). We show you facts, not recommendations. What you do with your money is your decision.
No false promises
We don't fabricate testimonials, inflate user counts, or claim features we haven't built. If something is coming soon, we say so. If we don't know something, we say that too.
Simple pricing
Free calculator, paid alerts. No hidden fees, no bait-and-switch, no "contact sales." You can see our pricing right on the homepage and cancel anytime.
Where our data comes from
All bond values, rates, and rules are derived from official US government sources. We don't make up numbers.
TreasuryDirect.gov
Official source for all savings bond rates, rules, and the government's own bond calculator.
treasurydirect.gov →Bureau of Labor Statistics
CPI-U inflation data that determines the variable component of I Bond rates.
bls.gov/cpi →Bureau of the Fiscal Service
Tracks matured unredeemed bonds — the $28.1B figure comes from their public reports.
fiscal.treasury.gov →What BondMinder is not
Being honest about our limitations is just as important as explaining what we do.
Not a financial advisor
We don't tell you what to do with your money. We show you facts and options. For personalized guidance, consult a qualified financial advisor.
Not affiliated with the Treasury
BondMinder is an independent tool. We are not affiliated with, endorsed by, or connected to the US Department of the Treasury or TreasuryDirect.
Not a place to buy or sell bonds
We don't sell securities. To buy savings bonds, visit TreasuryDirect.gov. To redeem, contact your bank or TreasuryDirect.
Not a guarantee of accuracy
Our calculations are estimates based on public Treasury data. For official bond valuations, use the TreasuryDirect savings bond calculator.
