How Much Do You Really Need in Treasury Bonds to Replace a $50,000 Salary With Interest

Replacing a $50,000 salary with Treasury interest is a clean math problem. Treasury interest sidesteps payout ratios, board votes on distributions, and NAV drift with the equity market. The only variables are the yield you lock in and the maturity you choose.

With the 10-year Treasury yielding 4.35% and the 30-year at 4.94%, government bonds are paying enough to replace a teacher’s salary, a paralegal’s income, or a modest retirement budget. The question is how much principal you need to put up to get there.

The Three Ways to Build $50,000 in Treasury Income

Each maturity gives you a different mix of yield, reinvestment risk, and lockup. Here is the capital required at each common entry point using current market yields.

1. The 30-year long bond. At a 4.94% yield, you need $1,012,146 to generate $50,000 a year. This is the most capital-efficient way to lock in the income, because the long end of the curve pays the highest rate. The tradeoff: your money is committed for three decades at a rate that may look small if inflation reaccelerates. Core PCE has climbed roughly 3% over the past year—a reminder that fixed coupons lose purchasing power when prices rise.

2. The 10-year note. At 4.35%, the math works out to $1,149,425. You give up roughly $137,000 of capital efficiency compared to the 30-year, but you get your money back in a decade and can reinvest at whatever rates exist then. The current 10-year sits in the upper quartile of its 12-month range, making today’s entry point reasonable rather than generous.

3. A five-rung ladder. Buying equal amounts of 1-, 3-, 5-, 7-, and 10-year Treasuries blends to roughly 4.08%, requiring $1,224,890 in capital. The ladder yields less than a single long bond, but a rung matures every year or two, giving you cash to reinvest if rates rise and steady income if they fall. With the 10Y-2Y spread at 0.52%, the curve is positively sloped enough to make laddering worthwhile.

Why Treasuries Beat Dividends for Some Investors

Three structural advantages matter here. Treasuries carry the full faith and credit of the US government, so credit risk is effectively zero. Interest is exempt from state income tax, which in California’s 13.3% top bracket is real money on every coupon. And if you hold to maturity, your principal comes back at par regardless of what bond prices do in the meantime.

What You Give Up

A $1.22 million Treasury portfolio stays at $1.22 million forever in nominal terms. CPI has risen roughly 3% over the past year, and that erosion compounds against a fixed coupon. A dividend growth portfolio yielding less today can raise its payout 6% to 8% a year. A Treasury cannot. When bonds mature, you reinvest at whatever the market offers, and the Fed Funds upper bound has already dropped from 4.5% to 3.75% over the past several months, showing how quickly the reinvestment landscape shifts.

Three Steps Before You Buy

1. Calculate your actual annual spending. If you live on $42,000, you do not need to replace $50,000, and the capital requirement falls accordingly.
2. Run the after-tax math in your state. The state-tax exemption on Treasury interest is worth more in California, New York, or Oregon than it is in Texas or Florida, and it can change which maturity is most efficient.
3. Decide whether you want certainty or growth. If the goal is a fixed paycheck for a fixed window, a ladder or long bond does the job. If you have 20 years and want income that keeps pace with prices, fixed coupons alone will lose the inflation race.
