How Much Is a $100 Savings Bond Worth?

It depends on the series and the issue date printed on the front. Rough ranges from the current Treasury tables:

• $100 EE bond (paper, cost $50): from ~$51 for recent issues to $200-$300+ for 1980s-90s bonds that ran their full 30 years.
• $100 I bond (cost $100): from ~$103 for recent issues to $300-$450+ for early 1998-2001 vintages that rode two decades of inflation adjustments.
• $100 Series E bond (cost $75): all matured — typically $400-$650+ depending on the year.

Those spans are exactly why a table of examples can't answer your question — but the official redemption tables can, to the penny. The calculator reads them directly: pick the series, choose $100, set the issue month, done.

Reading the bond's face

• Series — printed top right ("Series EE", "Series I", "Series E").
• Denomination — the big number; that's face value, not what was paid.
• Issue date — month and year, usually below the series; this drives the entire value calculation.

More than one bond?

Most people find savings bonds in stacks, not singles. Use the inventory to value the whole stack at once, see total interest earned, and flag any bond that has stopped earning.

Why two $100 bonds can be worth wildly different amounts

Denomination only tells you what's printed on the front — it says nothing about how long the bond has been compounding or which interest-rate rules applied to it. A $100 EE bond from 1985 and a $100 EE bond from 2015 both say "$100," but the 1985 bond has had three decades of compounding (and likely hit its 20-year doubling adjustment) while the 2015 bond is still early in its life. Issue date, not denomination, drives almost all of the variation in what a bond is actually worth today.

Other common denominations

The math scales linearly with face value, so once you know how a $100 bond of a given series and issue date behaves, a $50 bond of the same series and date is worth almost exactly half, and a $200 bond almost exactly double (small rounding differences come from how the Treasury tables round per $25 of face value). The calculator handles every standard denomination directly — $25, $50, $75, $100, $200, $500, $1,000, $5,000, and $10,000 — so there's no need to do that scaling by hand.

Ballpark by series (not a substitute for the exact check)

• Series EE: paper EE bonds were bought at half face value, so even a bond that has earned nothing yet is already worth more than $0 relative to its $50 purchase price; older EE bonds that have compounded for 20–30 years are typically worth 2–6× their original purchase price.
• Series I: bought at full face value, I bonds are always worth at least what you paid (composite rate can't go negative); bonds from high-inflation years can be worth notably more than face value after enough time.
• Series E: bought at 75% of face value and now uniformly matured, E bonds usually redeem for several times their face value simply because they had 30–40 years to compound before stopping.

These are rough shapes, not numbers to rely on — Treasury's published tables, read through the calculator, give the figure to the exact cent for your specific bond.
