Investments Chart of the Month

Chart of the Month – September 2025

When we take a step back and look at the big picture of U.S. government finances, the numbers are staggering.

The chart below shows two columns: The left represents where federal dollars are spent, and the right represents where they come from.

On the spending side, the largest items in the 2025 budget are Social Security ($1.57T), Medicare ($1.15T), and net interest on the national debt ($952B). Interest payments, alone, now exceed the entire defense budget!

On the revenue side, there is a gap between taxes and other sources of revenue and what is being spent. That gap, which we call the deficit, is $1.87T.

When we start throwing around numbers like billions and trillions, I like to remember a little math fact to keep them all in perspective. If you wait for one million seconds to pass by, that’s just over 11.5 days. If you wait for one billion seconds to pass by, that’s more than 31 years and 8 months! Now, if you want one trillion seconds to pass by, that’s over 31,688 years. These are really big numbers!

When numbers are this large, even meaningful revenue sources make only a dent. In July, the Department of Treasury tariff collections brought in just under $30B. Even with Congressional Budget Office estimates of possibly $2.5T over the next decade, the gap remains massive. Remember, the $1.87T deficit was just the shortfall for 2025, not for the decade.

For investors, this can have implications: Interest rates, tax policy, inflation, and corporate earnings can all be affected. At Foster Group, we believe educated optimism, like knowing the numbers, understanding the risks, and positioning portfolios with these in mind, is the best antidote to anxious uncertainty.

The federal budget reminds us that sound planning isn’t just for governments. It’s equally important for individuals, families, and institutions who want their wealth to thrive through changing economic conditions. If you’re wondering how these trends could affect your financial plan, let’s talk.
