A school bill is never one bill. Tuition arrives on one schedule. Notebooks, textbooks and fees arrive on others. The Bureau of Labor Statistics tracks these costs in separate pieces of the Consumer Price Index, and each piece moves on its own clock.
What the CPI measures for school costs
The CPI records what urban consumers pay for a representative basket of goods and services. Inside that basket, school spending is broken into detailed categories. The bureau's Economics Daily article on back-to-school spending covers price measures for educational books and supplies, alongside separate measures for tuition and fees.
Tuition has its own tracks. The bureau publishes factsheets on college tuition and fixed fees and on elementary and high school tuition and fixed fees. Books and supplies sit in another category entirely. A rise in one says little about the others, so each series needs to be read on its own.
What earlier figures show
Two older numbers help set the scene, and both need dates. According to a Bureau of Labor Statistics slideshow on consumer price trends, prices for educational books and supplies were 9.4 percent higher in May 2025 than in May 2024. That group includes elementary, high school and college textbooks and reference books. It is a twelve-month comparison for one month, not a current rate.
The same source says the overall CPI rose 2.9 percent between December 2023 and December 2024. The bureau called this disinflation. Prices still climbed, but by less than in the three previous twelve-month periods ending in December.
A cooler headline number does not mean school costs fell. The headline averages thousands of items. One category can keep rising quickly while the average slows. The bureau also noted that May 2025 was the latest available data for some school-related items when it published, a reminder that some school prices arrive with a lag.
Reading the monthly index values
For more recent months, FRED, the database run by the Federal Reserve Bank of St. Louis, republishes the bureau's series. One of them, CUSR0000SEEB, covers tuition, other school fees, and childcare. Childcare is part of this index, so it should not be read as a pure tuition measure. The values are seasonally adjusted, monthly, and use a 1982 to 1984 baseline of 100.
- May 2026: 912.006
- June 2026: 912.978
- July 2026: 917.923
- August 2026: 925.506
- September 2026: 930.897
From May to September 2026, that index rose about 2.1 percent. Over the same months, FRED's educational books and supplies series, CUSR0000SEEA, used the same baseline and adjustment:
- May 2026: 763.115
- June 2026: 770.541
- July 2026: 776.514
- August 2026: 770.986
- September 2026: 772.195
That series rose about 1.2 percent over the window, with a dip in August. Both calculations show short-term direction, not annual rates. FRED lists October 14, 2026 as the latest update and November 10, 2026 as the next release.
Why the time periods must stay separate
The 9.4 percent figure and the FRED values do not belong on one line. One compares May 2025 with May 2024. The others track five months in 2026. They cover different periods and different horizons, so they cannot be averaged or stitched into a single trend.
Details of each series matter too. Check the base year, the frequency and whether the numbers are seasonally adjusted before comparing anything. A year-over-year change and a month-to-month change answer different questions, and mixing them is an easy way to mislead yourself.
What the published numbers leave out
The figures here include no monthly values for these categories before May 2026, apart from the single May 2025 year-over-year number for books and supplies. Anyone who wants a longer history can pull the full series from the bureau or FRED. The bureau's detailed CPI table by expenditure category is where category-level results for each monthly release appear.
The CPI is also a price index, not a household budget. The sources used here do not explain how it treats student loan interest, general school-supply purchases by households, school meals or transportation. They also do not compare index movements with what families actually spend out of pocket. The bureau's Consumer Expenditure Survey is the place to look for spending data. For price direction, the separate series are the better guide.
