What is the I Bond rate for 2025?

I Bond rates change every 6 months based on inflation. The composite rate includes a fixed rate (set when you buy) plus an inflation rate that adjusts semiannually. Check TreasuryDirect.gov for current rates.

How much can I buy in I Bonds per year?

You can purchase up to $10,000 in electronic I Bonds per Social Security number per calendar year through TreasuryDirect. You can also buy up to $5,000 in paper I Bonds using your tax refund.

When can I cash in I Bonds?

I Bonds must be held for at least 12 months. If you redeem within 5 years, you forfeit the last 3 months of interest. After 5 years, there's no penalty.

Are I Bonds better than CDs?

I Bonds have advantages: inflation protection, tax deferral, and state tax exemption. CDs may be better if you need predictable rates, have more than $15,000 to invest, or need money within 12 months.

Only fixed portion is constant
High rates may not persist
