Counting in $illions

When SpaceX went public in June 2026, Forbes estimated Elon Musk’s net worth at more than a trillion dollars, making him the first person ever to cross that threshold. The number was so stratospheric that journalists struggled to explain what it meant.

Here is one comparison: A trillion dollars is approximately the amount spent on K–12 public education in an entire year in the United States. It is about 3.4% of everything the American economy produces annually. If we rename a trillion dollars as one Musk, U.S. public K–12 education costs about one Musk per year.

The comparison is imperfect, of course. Net worth is not cash, and the nation’s schools spend their money over time. But it gives an otherwise incomprehensible number some scale.

School boards, site councils, and PTAs need strategies to help members think clearly about mind-boggling figures. Big numbers come up constantly in conversations about education, and they get in the way of understanding. This post explores ways to turn blah-blah-blah into aha.

Big numbers need context

California’s public schools enroll about 5.7 million students. The state directs more than $100 billion per year to K–12 education. Oakland Unified School District (OUSD) has an annual budget of roughly $1 billion — and, as of this writing in 2026, faces a projected $38 million budget gap.

Without context, numbers like these can feel unreal and unanchored — almost silly, like Dr. Evil setting a ransom in an Austin Powers movie. We end up counting in $illions.

Our brains are not good at distinguishing large numbers. The difference between three and six feels obvious. The difference between $3 million and $6 billion is easy to miss, even though one is 2,000 times the other. Psychologists have found that people tend to perceive numbers logarithmically: differences between small numbers feel more vivid than differences between large ones.

Data journalists struggle with this problem. School board members, superintendents, union leaders and community advocates have to wrestle with it, too.

One way to demystify a large number is to break it up, dividing it by something people understand. In education, the most useful units are usually people and time — students, teachers, employees, classrooms, years, days and hours.

What does Oakland’s $38 million gap mean?

Case study: Oakland's $38 million gap

Is $38 million a big number? How worried should Oakland families and employees be?

Let’s give it some context using figures from Ed-data.org.

As a percentage: The gap is about 4% of OUSD’s total annual budget, which might sound minor until you consider what it pays for.

Per student: Oakland Unified enrolled about 43,500 students in 2025–26. Divided equally among them, a $38 million shortfall comes to about $875 per student.

Per employee: Does that still seem abstract? Consider it in terms of what school district budgets mainly pay for: people. The district employs roughly 5,500 teachers and other employees. The gap is equivalent to about $6,900 per OUSD employee.

As number of teacher salaries:With an average teacher salary of roughly $85,000, $38 million is approximately the pay of 450 teachers. It's not a perfect calculation, of course, and no district would actually solve a shortfall exclusively by eliminating teacher positions. Still, the comparison helps put the number into relevant human terms.

As time: Another way to consider the meaning of money is through the dimension of time. Spread across the district’s 180 instructional days, the $38 million gap comes to about $210,000 per day. Looked at another way, if OUSD’s roughly $1 billion annual budget were divided among those same 180 days, the shortfall would equal nearly seven days of total district spending. Again, it's an imperfect analogy — the district cannot legally cancel school days, and most school costs continue whether classes meet or not. Employees must still be paid, buildings maintained and debts honored. The calculation is a way to grasp the number, not a proposal to balance the budget.

Not all dollars are equal

In a school budget, some funds are restricted and can only be used in specific ways, like coupons. As explained in Ed100 Lesson 5.9, funds earmarked for capital expenditures (school facilities) cannot ordinarily be redirected to teacher salaries. In practice, when a district has to pare back a budget, the options are limited by laws and contracts.

The most flexible money in a budget is unrestricted and ongoing. Unfortunately, when cutting a budget unrestricted funds often have to absorb cuts because restricted funds cannot readily be redirected.

A school district can sometimes manage a one-time budget problem using reserves, delaying expenditures or relying on other one-time measures. A recurring or structural shortfall is more dangerous. Using reserves to cover it tends to postpone difficult decisions while making the district less able to handle the next emergency.

Details matter

Analogies and ratios like the ones suggested above can help boost general understanding, but in the end any conversation about big numbers becomes most meaningful through detail and stories.

Oakland’s $38 million shortfall is particularly difficult because enrollment is declining and its facilities are wearing out. California funds school districts according to student attendance. When attendance falls, revenue declines but many costs don't fall at the same speed. According to reporting by Ashley McBride for The Oaklandside, Oakland still operates 78 schools, virtually the same number as it did decades ago, when the district had twice as many students.

With 108 properties on more than 500 acres of land, OUSD has assets. But according to the district's draft 2026 Facilities Master Plan, it's complicated. Many of those assets are underused and some are in deep disrepair. Each school is its own story.

Translating numbers into meaning

There's no single way to express mind-numbingly big numbers meaningfully. Here are some ideas to consider:

Money is only good for what it can buy. Approaches like these can help provide a frame of reference to draw meaning from numbers that, without context, just sound big or mystifying.
