The fastest way: use the Treasury's online calculator

The U.S. Department of the Treasury runs a free tool called the Savings Bond Calculator that tells you exactly what any bond you own is worth today. You enter three pieces of information — the bond series (Series EE, Series I, or Series HH), the issue date printed on the bond itself, and the denomination (the face value, like $50 or $100) — and it shows you the current value in seconds.

You can find this calculator at treasurydirect.gov under the "Savings Bonds" section. The calculator updates every month when the Treasury announces new interest rates, so the value it shows you is current as of that month's rate announcement.

This method works whether you have the physical bond in your hand or you own bonds through a TreasuryDirect account online. If you own bonds through a bank or brokerage, they may also show you the current value in your account dashboard, but the Treasury calculator is the official source.

Key Takeaways

  • The Treasury's Savings Bond Calculator at treasurydirect.gov is the official tool for finding current bond value and requires only the series, issue date, and denomination.
  • Series EE and Series I bonds earn interest monthly but only show their full value when you cash them or at maturity, not on the physical bond itself.
  • If you own bonds through a TreasuryDirect account, you can also log in and see the value of each bond listed in your holdings.
  • The value shown includes all interest earned to date, so you do not need to calculate interest separately.
  • Bond value changes monthly when the Treasury announces new interest rates, so checking the calculator at different times may show different amounts.

What information you need to look up your bond's value

The bond itself — or your account statement if you own bonds online — will show you the series letter and the issue date. The series tells you what type of bond it is: Series EE bonds are the most common savings bonds sold to individuals, Series I bonds protect against inflation, and Series HH bonds are older bonds that may still be earning interest.

The denomination is the amount printed on the front of the bond or listed in your account. A $50 bond means you paid $25 for it (Series EE bonds sell at half their face value), but the denomination for the calculator is still $50.

If you have lost the physical bond or cannot find the issue date, you can still look up bonds you own through a TreasuryDirect account by logging in with your username and password. The account shows every bond you hold, its series, issue date, and current value all in one place.

Why the value on the bond itself is not the current value

Series EE and Series I bonds do not print the current value on the bond itself. Instead, they print the face value (the denomination) and the issue date. The actual value — what you would receive if you cashed it today — is calculated by the Treasury based on how much interest has accumulated since you bought it.

This is different from stocks or mutual funds, where the price changes constantly throughout the day. Savings bond interest rates are set by the Treasury and announced every six months, on May 1 and November 1. Your bond's value only changes on those two dates, not daily.

If you see a bond you own and want to know what it is worth right now, you cannot tell by looking at it. You have to use the calculator or check your online account.

How to read the calculator results

When you enter your bond information into the Treasury calculator, it shows you a single number: the current value. This is the amount you would receive if you cashed the bond today. It includes all interest earned from the issue date through the current month.

The calculator also shows you the next interest payment date — usually the first day of the next month — so you know when the value will increase again. If you are thinking about cashing the bond, knowing the next payment date can help you decide whether to wait a few days to capture the next month's interest.

The calculator does not show you a breakdown of principal plus interest. It just shows the total. If you want to know how much interest you have earned, subtract the amount you originally paid for the bond from the current value shown.

Checking your bonds through a TreasuryDirect account

If you own bonds through TreasuryDirect — the Treasury's online account system — you can see the value of each bond without using the calculator. Log in to your account, go to "Manage My Savings Bonds," and you will see a list of every bond you hold with its current value displayed next to it.

This method is faster if you own multiple bonds, because you can see all of them at once instead of entering each one into the calculator separately. The values in your account update on the same schedule as the calculator — on the first day of each month when new interest rates take effect.

If you have never set up a TreasuryDirect account but you own bonds purchased before the account system existed, you can still use the calculator. You do not need an account to look up the value of bonds you hold in paper form.

What happens if you cannot find your bond information

If you have a physical bond but the issue date is faded or illegible, you may still be able to read the series and denomination. The series letter is usually printed clearly on the front. If you can read those two pieces of information, you can contact the Treasury's Savings Bond Division by phone or mail to ask for help locating the issue date.

If you inherited bonds or received them as a gift and do not have any documentation, the Treasury can search their records if you provide the bond's series, denomination, and the name of the person who originally purchased it. This process takes longer than using the calculator, but it is possible.

For bonds held in a bank safe deposit box or stored away for years, the simplest approach is to bring them to your bank. Many banks can help you read the information on the bond and walk you through using the Treasury calculator.

Why bond value matters when deciding to cash or hold

Knowing your bond's current value helps you make decisions about whether to cash it now or wait. Series EE bonds, for example, have a may provide minimum value — if the bond has been held for 20 years, it is may provide to be worth at least twice what you paid for it, even if interest rates have been very low. Checking the calculator tells you whether your bond has already reached that may provide or whether waiting longer would increase its value.

Series I bonds have a different consideration: they stop earning interest after 30 years. If you own a Series I bond that is close to the 30-year mark, checking its value can help you decide whether to cash it before it stops earning interest or whether the current value is already high enough that waiting does not matter.

The calculator also helps you track your savings over time. If you check the value every six months, you can see how much interest you are earning and whether your bonds are growing the way you expected.

Frequently Asked Questions

Can I check the value of someone else's bond?

Yes, if you have the physical bond in your hand, you can use the Treasury calculator to find its value. You do not need to own the bond to look up what it is worth. However, if the bond is held in a TreasuryDirect account, only the account owner can log in and see the value.

Does the calculator show me how much interest I have earned?

The calculator shows the total current value, which includes interest. To find out how much interest alone, subtract what you originally paid for the bond from the value the calculator shows. For example, if you paid $25 for a Series EE bond and the calculator shows it is now worth $31, you have earned $6 in interest.

What if the calculator shows a different value than my bank statement?

This can happen if your bank's records have not updated yet after the Treasury announced new interest rates on the first of the month. The Treasury calculator is always current. Check the calculator again a few days later, and if your bank statement still shows a different value, contact your bank to ask them to update their records.

Do I need to pay taxes on the value the calculator shows?

The value shown is what the bond is worth, but you only owe taxes on the interest when you actually cash the bond or it reaches final maturity. The calculator does not tell you about tax obligations — that depends on your personal tax situation and when you cash the bond.

How often does the calculator value change?

The value changes once a month, on the first day of the month, when the Treasury announces new interest rates. Between those dates, the value stays the same. If you check the calculator on the 15th and again on the 25th of the same month, you will see the same value both times.
