How Much Interest Can $100, $1,000, or $10,000 Earn in 2026?

How Much Interest Can Your Savings Earn in 2026?

A note on the rates used in this guide: The FDIC’s national average savings account rate was 0.38% APY as of August 2026 — that figure is a verified benchmark. Online high-yield savings accounts have paid meaningfully more than the national average throughout 2026, but top rates move with the broader interest-rate environment and have trended lower over the course of the year; this guide uses 4.50% as an illustrative example of a competitive online rate, not a live quote. Always confirm a specific bank’s current published APY before making a decision — do not assume the 4.50% figure used in the examples below is still available.

At 4.50% APY (illustrative example rate) your money earns:

• $100 → $4.50 per year
• $1,000 → $45 per year
• $10,000 → $450 per year
• $100,000 → $4,500 per year

At the FDIC national average of 0.38% APY (August 2026):

• $10,000 → $38 per year
• $100,000 → $380 per year

At 0.01% APY (what Chase, Bank of America, and Wells Fargo pay on standard savings):

• $10,000 → $1.00 per year
• $100,000 → $10.00 per year

The account you choose determines almost everything.

Interest Earned by Balance and Rate — Annual Table

Annual interest estimates using simple APY calculation: Balance × APY. The 0.01% big-bank rate and 0.38% national average (FDIC, August 2026) are verified benchmark figures; the 4.50% and 4.35% columns are illustrative examples of competitive online HYSA and top 1-year CD rates as of September 2026, not live quotes — confirm current rates directly with a specific bank before relying on them. Actual interest may vary with compounding frequency.

Interest Earned Over Time at 4.50% APY

APY (Annual Percentage Yield) already reflects the effect of compounding, so growing a balance over multiple years means compounding the APY itself: Balance × (1 + APY)^years. Here’s what $10,000 grows to at a steady 4.50% APY, assuming the rate never changes (unrealistic over long periods, since rates move, but useful for comparison):

Assumes a constant 4.50% APY every year with no withdrawals — in reality, published APYs change over time, so treat this as an illustrative projection, not a guarantee.

Interest by Account Type (Same $10,000)

Rows marked “illustrative” are example rates, not live quotes — confirm the current published rate for any specific product before making a decision, since these move with the broader interest-rate environment. The I Bond and Treasury bill figures are sourced from TreasuryDirect and the U.S. Treasury’s daily par yield curve as of the dates noted.

How Bank Interest Is Calculated

Most savings accounts use daily compounding, which means:

1. The bank divides your APY by 365 to get the daily rate
2. Each day, it multiplies your balance by that daily rate to calculate interest earned
3. That interest is added to your balance
4. The next day’s interest is calculated on the slightly larger balance

Example — $10,000 at 4.50% APY: Because APY is already the effective annual rate after compounding, the calculation for one year is simply: $10,000 × 4.50% = $450 in interest, for a year-end balance of $10,450. You don’t need to separately compound a daily rate — that would double-count the compounding effect and overstate your return. Banks that compound daily disclose both a nominal rate and an APY; the APY is always the number to use for your annual estimate.

The APY already accounts for compounding, so for a quick estimate: Annual interest ≈ Balance × APY.

What About CD Interest?

CDs pay a fixed APY for a set term. Interest may compound daily and be credited monthly, or credited at maturity, depending on the bank and term.

Example — $10,000 in a 1-year CD at 4.35% APY (illustrative):

• At maturity (12 months): $10,435 total ($10,000 principal + $435 interest) — since APY already reflects compounding, no further adjustment is needed for a 1-year term

Multi-year CDs compound year over year:

• $10,000 in a 5-year CD at 4.50% APY (illustrative):
  • Year 1: $10,450
  • Year 2: $10,920
  • Year 3: $11,412
  • Year 4: $11,925
  • Year 5 (maturity): $12,462 — total interest: $2,462

Tax on Savings Interest

Savings account interest is taxable as ordinary income. The bank reports annual interest on Form 1099-INT.

Example — $10,000 at 4.50% APY:

• Interest earned: $450
• Tax owed (22% federal bracket): $99
• After-tax interest: $351
• After-tax effective yield: 3.51%

To reduce tax on interest:

• Hold savings in a Roth IRA (tax-free growth on qualifying withdrawals)
• Hold savings in a traditional IRA (tax-deferred growth)
• Consider Treasury bills, which are exempt from state income tax in all 50 states
