What Are I Bonds?
I Bonds are a type of savings bond issued by the U.S. Treasury. They are designed to protect against inflation and are generally considered a safe investment because they are backed by the government.
I Bonds are essentially a loan to an entity (in this case the U.S. government), with the promise to return an investor’s money, typically with interest. These bonds also offer some tax advantages.
If you’re considering buying I Bonds and you’re wondering, how do I Bond work?, here’s what you need to know.
Key Points
• I Bonds are government-backed savings bonds designed to be low-risk.
• The interest rate of I Bonds combines a fixed rate and an inflation rate, adjusted semi-annually, which together provide the bonds’ composite rate.
• Tax benefits include exemption from state and local taxes, and possible deferral of federal taxes.
• Purchase limits of I Bonds are set at $10,000 per individual annually.
• I Bonds must be held for 12 months before redemption. Cashing them in before holding them for five years incurs a penalty of the last three months’ interest.
How Do I Bonds Work?
I Bonds are a type of savings bond offered by the U.S. Treasury and backed by the full faith and credit of the U.S. government. These bonds offer two types of interest payments: a fixed rate and an inflation rate, which together provide the bond’s composite rate (or yield).
The fixed-rate portion is determined when the bond is purchased, and it remains the same for the life of the bond. The variable rate gets adjusted twice a year, based on inflation rates. The composite rate on I Bonds issued as of November 1, 2024 is 3.11%. If you’re wondering how that rate compares to the interest rate on other types of savings vehicles, the rate on a 60-month certificate of deposit (CD) in November 2024 was 4.15% , for example, and the average rate on a high-yield savings account was more than 4%.
Because I Bonds are backed by the U.S. government, they are designed to have a low risk of default. Furthermore, the principal is guaranteed. This is one of the advantages of savings bonds overall. As a result, I Bonds are generally considered low-risk investments.
Individuals who buy I Bonds must hold them for at least 12 months before cashing them in. if they redeem the bonds before the five-year mark, they will lose the last three months of interest. Investors can hold onto I Bonds for up to 30 years, when they reach maturity.
While paper I Bonds used to be available in certain circumstances, starting January 1, 2025, all new I Bonds will be electronic.

How Do You Calculate I Bond Interest Rate?
If you are interested in buying bonds like I Bonds, you’ll want to know how to figure out the interest rate. To calculate the I Bonds interest rate, you combine the fixed rate and inflation rate to get the composite rate.
For example, if you bought I Bonds in November 2024 when the fixed rate was 1.20% and the inflation rate was 0.95%, to calculate the composite rate you would use this formula:
Plugging in the actual numbers, it would be:
Using these numbers, you’ll earn 3.11% interest on the amount you invested in I Bonds for six months, at which time the rate may change again. So if you invested $1,000 in I Bonds, you would earn $15.55 in interest in six months. The earnings would then be added to your original investment, and for the next six months you would earn interest on that new, higher amount of $1,015.55.
One thing to keep in mind is that if you cash in I Bonds before five years, you will lose the last three months worth of interest. So, if possible, you may want to hang onto them for five years to avoid giving up interest you may have earned.

Are I Bonds Still a Good Investment?
Whether I Bonds make sense for you as an investment depends on a number of factors, your financial goals, risk tolerance, overall investment strategy, and timeline.
Benefits of I Bonds
I Bonds have a number of potential advantages. These include:
• Lower risk: I Bonds are designed to be a low-risk investment, backed by the U.S. government. If you have a low risk tolerance, I Bonds may be a good choice for you. Also, if you’re looking for a place to park money that you’ll need in five or so years — for a down payment on a house, say — I Bonds can offer a low-risk option.
• Protection against inflation: I Bonds can help protect your purchasing power in times of high inflation. If inflation rises, the interest rate on I Bonds rises as well. For instance, in May 2022, when inflation was high, I Bonds paid a composite rate of 9.62%. As of November 1, when inflation was much lower, the composite rate on I Bonds issued was 3.11%.
• May offer tax advantages: While there are federal taxes on I Bonds, there are no state and local taxes on them.
Drawbacks of I Bonds
There are some downsides to investing in I Bonds, however, such as the following:
• Time commitment: I Bonds must be held for at least 12 months before they can be redeemed.
• Possible interest penalty: You’ll lose the last three months’ worth of interest if you sell I Bonds before the five-year mark.
• Purchase limit: Individuals can purchase no more than $10,000 worth of electronic I Bonds each year through the U.S. Treasury’s Treasury Direct.
• Lower interest rate: The interest rate may be lower for I Bonds than for some other investments.
• Hard to predict return over time: To maximize your return on investment when purchasing I Bonds, it’s important to understand how the two interest rate components of the bond can play out over time. As mentioned, the fixed interest rate remains the same for the life of the bond. But the inflation rate of the bond adjusts with changes in inflation rates twice per year. If inflation goes up, so does the bond’s inflation rate. If inflation goes down, the bond’s inflation rate would likewise decrease as well.
I Bonds vs EE Bonds
Investors considering buying savings bonds may want to compare I Bonds and EE Bonds. The two types of bonds have many similarities but also a few key differences.
Similarities
You can buy both EE Bonds and I Bonds from Treasury Direct. Both types of bonds are backed by the full faith and credit of the U.S. government, and they are each designed to be a low-risk investment. They both mature in 30 years.
I Bonds and EE Bonds each have a purchase limit of $10,000 per individual per year.
Differences
One of the main differences between EE Bonds and I Bonds is that EE bonds issued after May 2005 have a fixed interest rate that doesn’t change for at least the first 20 of its 30 years, while I Bonds have a composite rate that combines a fixed rate and an inflation rate, which changes every six months. The interest rate for EE Bonds bought as of November 1 is 2.60%.
One unique feature of EE Bonds is that, over a 20-year period, these bonds are guaranteed to double in value. While I Bonds don’t offer the same guarantee, your principal is guaranteed and the bonds are designed to keep pace with inflation.
Do You Pay Taxes on I Bonds?
Tax-efficient investors may want to consider certain I Bond features. For instance, I Bonds are exempt from local and state taxes. While federal taxes usually apply, they could be deferred until the bond is ultimately sold or matures; whichever happens first.
Additionally, I Bond investors may use the interest payments for qualified higher education expenses and receive a 100% deduction. Some restrictions apply, including:
• You must cash out your I Bonds the year that you want to claim the exclusion.
• Your modified adjusted gross income must be less than the cut-off amount the IRS sets for the year.
• You must use the interest paid to cover qualified higher education expenses for you, your spouse, or your dependent children the same year.
• You cannot be married, filing separately.

How Do You Buy I Bonds?
You need to meet certain criteria to purchase I Bonds. To be eligible to buy I Bonds you must be:
• A United States citizen, no matter where you live
• A United States resident, or
• A civilian employee of the United States, no matter where you live
If you are eligible to purchase them, buying I Bonds is easy. As previously mentioned, individuals can purchase electronic I Bonds online through Treasury Direct, after setting up a Treasury Direct account. They can be bought in denominations starting at $25. The maximum amount of electronic I Bonds someone can purchase is $10,000 per calendar year.
The Takeaway
If you’re looking for an investment that’s designed to be safe, I Bonds may be worth considering. They are backed by the U.S. government and offer protection from inflation, certain tax advantages, and other benefits that may make them a low-risk choice for your savings goals. However, because I Bonds come with a composite rate of return, it’s hard to predict how much your money will actually earn over time.
If you’re interested in different savings vehicles, there are alternatives to I Bonds, including CDs and high-yield savings accounts. By exploring your options, you can determine the best choice — or choices — for you and your financial goals.

FAQ
How Long Do I Bonds Take to Mature?
I Bonds reach maturity in 30 years. You can redeem I Bonds after holding them for 12 months, but if you cash in I Bonds in less than five years, you’ll lose the last three months of interest.
How Often Can You Buy I Bonds?
In one calendar year, an individual can buy up to $10,000 worth of I Bonds. The limit is counted by the Social Security number of the first person listed on the bond, according to Treasury Direct. If you are a co-owner of I Bonds and the second person named on the bonds, those bonds will not count toward your limit.
In addition, if you give I Bonds as a gift, those bonds count toward the limit of the recipient, not you as the giver.

4.00% APY
SoFi members with direct deposit activity can earn 4.00% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Direct Deposit means a recurring deposit of regular income to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government benefit payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below). Deposits that are not from an employer or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, or are non-recurring in nature (e.g., IRS tax refunds), do not constitute Direct Deposit activity. There is no minimum Direct Deposit amount required to qualify for the stated interest rate. SoFi members with direct deposit are eligible for other SoFi Plus benefits.
As an alternative to direct deposit, SoFi members with Qualifying Deposits can earn 4.00% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant. SoFi members with Qualifying Deposits are not eligible for other SoFi Plus benefits.
SoFi Bank shall, in its sole discretion, assess each account holder’s Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving a Direct Deposit or $5,000 in Qualifying Deposits to your account, you will begin earning 4.00% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.
SoFi Bank reserves the right to grant a grace period to account holders following a change in Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Direct Deposit or Qualifying Deposits until you have Direct Deposit activity or $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Direct Deposit.
Members without either Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, will earn 1.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances.
