How Much Can You Earn from Treasury Bonds? Calculations and Examples for 2026

How Much Will You Really Earn from Treasury Bonds?

This is the most common question from anyone considering Treasury bonds. Yields of 4–5% sound attractive, but what does that mean in practice? Let's run the numbers for different amounts and time horizons.

All calculations use early 2026 rates and account for federal income tax (assuming 24% bracket). Treasury interest is exempt from state and local taxes.

T-Bills (3–6 Months) — Short-Term Parking

$10,000 in 6-Month T-Bills at 4.50%

• Interest earned: $225
• Federal tax (24%): $54
• Net interest: $171
• Annualized net return: ~3.42%

$50,000 in 6-Month T-Bills at 4.50%

• Interest earned: $1,125
• Federal tax (24%): $270
• Net interest: $855
• Annualized net return: ~3.42%

$100,000 in 6-Month T-Bills at 4.50%

• Interest earned: $2,250
• Federal tax (24%): $540
• Net interest: $1,710
• Annualized net return: ~3.42%

Takeaway: T-Bills are great for short-term cash parking — you earn more than any savings account with zero risk.

1-Year Treasury Notes — 5.00% Yield

$10,000 for One Year

• Interest earned: $500
• Federal tax (24%): $120
• Net interest: $380
• Net return: 3.80%

$50,000 for One Year

• Interest earned: $2,500
• Federal tax (24%): $600
• Net interest: $1,900
• Net return: 3.80%

$100,000 for One Year

• Interest earned: $5,000
• Federal tax (24%): $1,200
• Net interest: $3,800
• Net return: 3.80%

Takeaway: A solid return for a one-year commitment — significantly better than most bank CDs.

TIPS (5–10 Years) — Inflation-Protected

TIPS adjust your principal with inflation, plus pay a fixed real yield on top. Let's model a 10-year TIPS with 1.75% real yield.

$100,000 in 10-Year TIPS (Inflation averages 3.0%)

Simplified annual calculation:

After 10 years:

• Principal returned: $134,392 (inflation-adjusted)
• Total coupons: ~$20,500
• Total value: ~$155,000 (pre-tax)
• Real return: 1.75%/year guaranteed above inflation

Takeaway: TIPS guarantee your purchasing power grows by 1.75% annually, regardless of what inflation does.

I Bonds (1–30 Years) — The Retail Favorite

I Bonds combine a fixed rate with semiannual inflation adjustments. Assuming a 1.20% fixed rate and varying inflation.

$10,000 in I Bonds Over 5 Years

Assumed inflation: 3.5%, 3.0%, 2.5%, 3.0%, 3.5%

After 5 years (redeeming after holding period):

• Value: ~$14,288
• Gain: $4,288 (42.9% total)
• Tax (24% on gain): ~$1,029
• Net gain: ~$3,259
• Annualized net return: ~6.0%

Note: If used for qualified education expenses, the gain can be 100% tax-free.

Bond Ladder Strategy — Regular Income

Instead of one lump-sum investment, you can build a "ladder" — buying bonds at regular intervals.

Example: $2,000/Month in T-Bills (Rolling 6-Month Ladder)

Year 1: Buy 6-month T-Bills monthly Year 2: Each month, a T-Bill matures + you reinvest with new money

After 3 years: ~$78,000 in capital generating ~$2,700/year in net interest.

Comparison with Other Investments

T-Bills vs CDs vs Savings Accounts

$50,000 for one year:

Advantage of Treasuries: $292–$1,748 more than alternatives, plus state tax exemption!

Bonds vs Inflation — Real Returns

Assuming 3.0% inflation:

Takeaway: All Treasury bonds beat inflation in the current rate environment. I Bonds and TIPS offer the strongest real returns.

How Much Do You Need to Live Off Bond Interest?

Monthly Expenses: $4,000 ($48,000/Year)

Capital needed in 1-Year Treasuries (3.80% net): $48,000 ÷ 0.038 = $1,263,000

Capital needed in TIPS (1.75% real after tax ~1.33%): $48,000 ÷ 0.0133 = $3,609,000 (but inflation-protected!)

Monthly Expenses: $6,000 ($72,000/Year)

Capital needed in 1-Year Treasuries: $72,000 ÷ 0.038 = $1,895,000

Takeaway: Living solely off bond interest requires $1–2M+ in capital. Bonds are a foundation, not typically a sole income source.

Strategy by Financial Goal

Emergency Fund (3–6 Months of Expenses)

• Amount: $15,000–$30,000
• Bond type: T-Bills (4–13 weeks)
• Annual earnings: $500–$1,000 net
• Goal: Liquidity first, returns second

Medium-Term Savings (1–5 Years)

• Amount: $50,000
• Bond type: T-Bills + I Bonds
• Annual earnings: ~$2,000–$3,000 net
• Goal: Beat inflation, preserve capital

Long-Term Wealth Building (5+ Years)

• Amount: $200,000
• Bond type: TIPS + I Bonds
• Annual earnings: ~$6,000–$10,000 net
• Goal: Inflation-protected growth
