Hourly Pay Rose Five Cents, but Purchasing Power Fell. What to Watch in October’s Inflation Release

Energy showed the largest September increase among the three essentials below. Prices for energy rose 5.2% in one month, while food prices held steady. Over that same month, an hour of work bought 0.5% less on average across private nonfarm payrolls.

Monthly changes are seasonally adjusted except where starred. Annual CPI changes are unadjusted. Earnings changes are seasonally adjusted. *The monthly change for food away from home is unadjusted. Both releases were published October 14. September CPI, Table A · September Real Earnings, Table A-1.

Overall prices rose 0.1% in July, 0.4% in August and 0.6% in September. Core prices rose 0.3% in September. A driver faced a much sharper price change at the pump than a household paying for electricity. These categories overlap with broader indexes, so adding the rows would double-count some purchases.

Gasoline prices rose 9.1% and contributed 0.337 percentage point to the monthly all-items CPI change. Shelter contributed 0.138 point. These contributions reflect the weight of each category in the index. BLS CPI, Table 6.

Average hourly earnings rose from $37.76 to $37.81 from August to September. That was a 0.1% nominal gain. Consumer prices rose 0.6%, leaving real hourly earnings down 0.5%. BLS divides nominal hourly earnings by the CPI-U and multiplies by 100 to express pay in constant dollars. BLS Real Earnings, Table A-1.

Divide September’s $37.81 by the September CPI-U of 336.298 and multiply by 100. The result is $11.24 in 1982–84 dollars, down from $11.30 in August. The CPI base is 100 for the 1982–84 average. The $11.24 figure expresses the wage at that period’s average prices. Expressing both wages in dollars of the same period lets us compare what an hour bought. BLS marks September earnings as preliminary.

To check your own paycheck, compare two pay stubs covering the same number of weeks. Check your hourly rate, paid hours and overtime first, then compare taxes, insurance deductions and the amount deposited. A raise can coincide with a smaller deposit if you worked fewer hours.

For a household budget, subtract groceries, housing, utilities and commuting costs from each period’s take-home pay. Compare what was left. If a bill rose sharply, check both the unit price and how much you used.

A two-week budget example

Suppose a worker’s deposit rises from $1,500 to $1,520 across two equal pay periods. If essential bills rise from $1,100 to $1,135, the cash left after those bills falls from $400 to $385. The $20 increase in the deposit covered only part of the $35 increase in bills. The subtraction is $1,500 − $1,100 = $400 and $1,520 − $1,135 = $385. These are hypothetical dollars. To use the example, compare your own deposits and assign the same share of monthly bills to each pay period.

Two years of September pay comparisons

From September 2024 to September 2025, average hourly pay rose 3.8% and real hourly pay rose 0.8%. Over the following year, nominal pay rose 3.0% while real hourly pay fell 0.7%. Both comparisons cover employees on private nonfarm payrolls. BLS Table A-1.

Same paycheck, different September bills

These two hypothetical households each take home $3,000 and spend $2,500 a month. A drives more. B spends more on rent. We hold quantities, take-home pay and other bills fixed. Each cell gives starting spending and its dollar change.

Multiply starting spending by each percentage, then add the changes. A loses $37.80 of monthly cash and B loses $11.10. Moving $300 of starting spending from gasoline to rent explains the $26.70 difference. Actual bills depend on local prices, lease terms and usage. BLS CPI, Tables A and 1.

The 2025 federal shutdown interrupted price collection. For most CPI series, BLS could not publish an October 2025 index. Wherever that starting value is missing, the agency will omit the October 2026 twelve-month change. An empty entry does not mean that prices stood still. BLS shutdown FAQ, question 16.

Start with the September-to-October changes for shelter, food and energy. Then look at real average hourly earnings over the same month. BLS already adjusts this measure for consumer prices. Weekly earnings can move differently when the workweek changes.

A renter who drives to work and a homeowner who takes the bus can experience the same national figures differently. The national indexes cannot determine either household’s personal inflation rate or take-home pay.

October results are pending as of November 9. Both releases are scheduled for November 10 at 8:30 a.m. Eastern (6:30 a.m. Phoenix). BLS release calendar.

The Federal Reserve measures its longer-run 2% inflation goal using the personal consumption expenditures price index. October CPI can inform expectations about interest rates, but a single release cannot determine the next rate decision. Federal Reserve explanation of the inflation target.

If your pay agreement includes a cost-of-living adjustment, check which index it names, which months it compares and when the adjustment takes effect. Those terms determine how a price change feeds into your raise. BLS guide to using CPI for escalation.

Seasonal adjustment helps account for recurring price patterns. Energy prices can still swing sharply from month to month. September’s gasoline reading alone cannot identify the cause or predict October’s change.

Hypothetical contract example: a January adjustment of 3% on a $25 hourly rate adds $0.75 per paid hour starting in January. A 40-hour week would earn $30 more before deductions. Check the effective date and paid hours on the first affected pay stub.

Enter your take-home pay, expenses and starting savings. Set annual changes in pay and household prices, then choose how many months to project. The table shows each month’s cash left, cumulative savings and paycheck in today’s dollars.

Headline CPI measures the full consumer basket. Core CPI excludes food and energy, two expenses many households pay every week. A monthly change shows recent movement, while a twelve-month change covers a longer spending cycle. For a wage negotiation, compare the raise and price change over the same period.

Hypothetical one-year budget. With $4,000 monthly take-home pay and $3,000 in expenses, $1,000 is available to save. If pay rises 2% and expenses rise 4%, monthly pay reaches $4,080 and expenses reach $3,120. That leaves $960 to save, or $40 less per month. Measured in starting-year dollars, the new paycheck buys about $3,923 ($4,080 ÷ 1.04).

If the annual changes phase in evenly each month and starting savings are zero, this example accumulates $11,743.10 over twelve months. It assumes unchanged spending quantities, no interest and that each month’s surplus goes into savings.

For month t, deposit = $4,000 × 1.02^(t/12), expenses = $3,000 × 1.04^(t/12), and surplus = deposit minus expenses. Sum the unrounded surpluses for months 1 through 12. Divide a future deposit by 1.04^(t/12) to express it in starting-period dollars.
