Picture Marcus, an imagined landscaper who stands in for many real owners. He runs a small company outside Wilmington, and he has not changed his prices in two years. Fuel, equipment, and workers all cost more than they did when he printed his price list, and he knows it. He keeps meaning to fix it, every spring and every fall. Each time, the same worry stops him: if he raises his prices, the customers he worked hard to win might quietly start calling someone else.

It is October, and that worry now has a deadline. The prices a business takes into January are the prices its customers will live with for most of the next year. Marcus is deciding whether to act or to wait, even if he has not noticed that waiting is a decision too.

What Is Happening to Your Costs

The government’s report for August shows prices up 3.4 percent over the past 12 months (BLS, 2026). That one number hides a big spread. Energy rose 16.3 percent, shelter costs rose 3.0 percent, food rose 2.7 percent, and everything except food and energy rose 2.4 percent (BLS, 2026). A business that burns a lot of fuel has a much rougher year than one that mostly sells its own time.

Owners have noticed. In the August survey from the National Federation of Independent Business, 16 percent of owners said inflation was their biggest problem, up 2 points from the month before and tied with taxes as the second biggest worry (NFIB, 2026). The Federal Reserve acted too. On September 16, it raised its main interest rate by a quarter of a point, to a range of 3.75 to 4.00 percent (Federal Reserve, 2026). That was its first increase since July 2023, and 16 of the 18 Fed officials who shared their forecasts expect another one before the year ends (Chase, 2026).

None of this guarantees that costs will keep rising at the same speed. But it is a good reason to stop assuming they will settle back down on their own.

Why Price Has the Biggest Effect on Profit

When costs go up, an owner has three basic choices: keep prices where they are, raise them, or give customers less for the same price (HBR, September 2026). Of those three, price has the biggest direct effect on profit. A McKinsey study looked at the average income statement of a company in the S&P 1500, a group of 1,500 publicly traded companies. It found that raising prices by 1 percent, with sales staying the same, increased operating profit by 8 percent. That was nearly 50 percent more than the effect of cutting costs like materials and labor by 1 percent, and more than three times the effect of selling 1 percent more (McKinsey Quarterly, 2003).

That study covers publicly traded companies and dates to 2003, so the exact numbers will not match a small business. The basic idea still holds, because an extra dollar of price does not come with an extra dollar of cost. The opposite is also true. Prices that stay flat while costs rise are not neutral. They slowly move money out of the business every month, and the owner pays for it in profit.

Will Your Customers Leave?

This is the fear that keeps most owners from acting, and it deserves a real answer, starting with a fair warning. In June, Harvard Business Review shared pricing strategist Rafi Mohammed’s argument that after six years of steady price increases, customers have grown wary. He urged companies to survey their customers and review their deals with suppliers before changing prices (HBR, June 2026).

The evidence on how a price increase lands is more useful than the fear. It suggests that how you explain an increase changes how many customers walk away. A study in the Journal of Marketing, reported by Inc., tested explanations for a price increase based on market conditions, rising costs, and product quality, on more than 1,600 customers of a Canadian self-storage company. The explanation based on market conditions, like strong demand and few competitors, lost the fewest customers, even though customers still saw it as relatively unfair. Explanations based on rising costs may no longer be seen as fair during a long stretch of inflation, and explanations based on quality got a mixed reception (Inc., 2026). Use the market explanation only if it is true.

Giving customers less carries its own risk. Marketing professor Ioannis Evangelidis described 25 experiments with more than 30,000 consumers. Shoppers judged quality cuts to be less fair than either price increases or smaller package sizes, and once they noticed a cut, they were less willing to keep buying (HBR, September 2026). Those experiments may not carry over fully to services, but the warning is still worth taking seriously. Quietly rushing a job, trimming a service, or dropping a perk to protect profit can cost more trust than an honest, well explained price change.

How to Do It Before January 1

Timing is where Marcus has an advantage. Xero, an accounting software company, advises giving most customers 30 to 60 days of notice before a price change. For a January 1 change, that means sending notices between early November and early December. The same guidance says to call your biggest customers personally before any general announcement, to state both the percentage and the dollar amount of the increase, and to avoid your busiest seasons (Xero, 2026).

Xero also suggests reviewing your prices at least once a year, and notes that a 3 to 5 percent increase is often easier for customers to accept than a large jump (Xero, 2026). That matters for an owner like Marcus, who has waited two years, because the increase needed to catch up may now be bigger than that range.

A simple order of steps works well. First, know your numbers: what each job or product costs you now, and how much profit is left. Review your deals with suppliers before changing prices (HBR, June 2026), and check your contracts for any notice you are required to give. Counting back from January 1, the new prices need to be set in October. Then tell your best customers first and send the general notice in November, in line with Xero’s 30 to 60 day guidance (Xero, 2026).

When you explain the change, keep it short and plain. If higher costs are the reason, say so, but know that cost explanations may no longer be seen as fair during a long stretch of inflation (Inc., 2026). If strong demand or limited supply is also true for your business, say that too.

The Bottom Line

Costs are still rising unevenly, the Federal Reserve raised interest rates in September and signaled more, and the prices a business carries into January will shape its profit for most of 2027. Raising prices carries real risk, and the evidence suggests that risk depends a lot on how you explain the change and how much notice customers get. Holding prices flat carries risk too, but it shows up slowly, in profit, where customers are unlikely to complain about it. An owner who decides in October, with real numbers and an honest explanation, is in a much stronger position than one who waits for a perfect moment that rarely comes.

Strategic Consulting

Consider a small service company whose published price list was last revised two years ago. Its input costs, including fuel, equipment, and labor, have moved since that revision, but its revenue per unit of work has not. The owner recognizes the margin gap and has deferred the adjustment through two consecutive seasons, citing customer retention risk. The relevant question is not whether to adjust but when, and the calendar supplies an answer: a price list adopted in the fourth quarter governs the following year’s margin structure.

I. The Cost Environment

The August Consumer Price Index showed a 3.4 percent increase over 12 months, with energy up 16.3 percent, shelter up 3.0 percent, food up 2.7 percent, and the core measure excluding food and energy up 2.4 percent (BLS, 2026). The dispersion matters for pricing decisions, because an input mix weighted toward energy faces cost pressure well above the headline rate, while a labor weighted service firm faces a different profile. Owner sentiment reflects the pressure: 16 percent of respondents in NFIB’s August survey named inflation as their single most important problem, up 2 points and tied with taxes as the second most cited concern, even as the share citing labor costs fell to its lowest level since March 2021 (NFIB, 2026).

Monetary policy has not signaled relief. The Federal Reserve raised its target range by 25 basis points to 3.75 to 4.00 percent on September 16 in a unanimous 12 to 0 vote (Federal Reserve, 2026). It was the first increase since July 2023, and 16 of 18 participants in the September projections expect a further increase this year, with the next meeting scheduled for October 27 and 28 (Chase, 2026). The September CPI release, due October 14, will update the inflation picture before that meeting (Chase, 2026).

II. The Profit Arithmetic of Price

In a McKinsey Quarterly analysis based on the average income statement of an S&P 1500 company, a 1 percent price increase with stable volume produced an 8 percent increase in operating profit, an effect nearly 50 percent larger than a 1 percent reduction in variable costs and more than three times that of a 1 percent increase in volume (McKinsey Quarterly, 2003). Two limitations apply. The sample consists of publicly traded companies, not small firms, and the analysis is more than 20 years old, so the specific multiple should not be transplanted onto a small firm’s income statement. The mechanism, however, is structural rather than size dependent: incremental price flows to operating profit without incremental cost, which is why its effect exceeds that of the alternatives.

The corollary is that a price list held flat against rising costs transfers margin out of the business continuously, and the transfer is invisible in customer feedback, because customers are unlikely to complain about prices that do not rise. Owners facing cost pressure have three basic options: hold prices, raise them, or reduce what the customer gets for the same price (HBR, September 2026).

III. The Customer Response Question

Retention risk is the standard objection, and the evidence supports taking it seriously while also showing it is manageable. Harvard Business Review’s June 2026 presentation of pricing strategist Rafi Mohammed’s argument holds that after six years of steady price increases, customers have grown wary, and that companies should survey their customers and review supplier agreements before changing prices (HBR, June 2026).

On the question of how an increase should be framed, a study in the Journal of Marketing, reported by Inc., tested explanations for a price increase based on market conditions, rising costs, and product quality on more than 1,600 customers of a Canadian self-storage company. The market forces explanation, citing high demand and limited competition, produced the lowest customer attrition, although customers still perceived it as relatively unfair. Cost based explanations may no longer be seen as fair during prolonged inflation, and quality based explanations received a mixed reception (Inc., 2026). The practical boundary is that the market forces framing is appropriate only where it is accurate.

Alternatives to a price increase carry their own penalty. The 25 experiments Ioannis Evangelidis describes, involving more than 30,000 consumers, found that quality reductions were judged less fair than price increases or smaller package sizes, and that customers who discovered a reduction were less willing to continue buying (HBR, September 2026). Experiments on products do not transfer automatically to services, but the direction of the result argues against protecting margin through undisclosed reductions in what customers receive.

IV. Sequencing Against a January 1 Effective Date

Business guidance from Xero recommends 30 to 60 days of notice for most customers, personal contact with key accounts before any general announcement, an explicit statement of both the percentage and the dollar change, and avoidance of busy seasons (Xero, 2026). For a January 1 effective date, 30 to 60 days of notice places the general announcement between November 2 and December 2. Working backward, the pricing decision itself should be complete by the end of October, leaving November for conversations with key accounts and general notices. Any customer agreement containing price change notice provisions should be reviewed before dates are set.

The same guidance advises an annual price review and notes that a 3 to 5 percent increase is often easier for customers to accept than a large jump (Xero, 2026). That bears on owners who have deferred adjustment through multiple seasons, since the catch up they face may be larger than that range.

V. Practical Implications for Owners

Several actions follow from the above. First, establish current unit economics: the fully loaded cost of each service or product line and the margin it now produces, since the price decision should rest on those figures rather than on the headline inflation rate. Second, review supplier agreements before changing prices (HBR, June 2026). Third, review customer agreements for notice requirements on price changes. Fourth, set the new price list by the end of October. Then contact the most important accounts personally and issue general notices in November, stating the change in both percentage and dollar terms, consistent with the Xero guidance (Xero, 2026). Fifth, choose the explanation deliberately: where strong demand or limited alternatives genuinely describe the business, say so, and where the driver is cost, state it briefly while recognizing that cost explanations may no longer be seen as fair after years of inflation (Inc., 2026). Sixth, avoid offsetting the increase with unannounced reductions in service or quality (HBR, September 2026).

VI. The Bottom Line

Cost pressure remains uneven but persistent, the Federal Reserve raised rates in September and signaled another increase, and a price list adopted in the fourth quarter governs margin through most of the following year. The evidence does not support the view that a price increase is costless, nor the view that it is uniquely dangerous: attrition risk varies with the quality of the explanation and the adequacy of the notice, and the principal alternatives, holding prices flat and undisclosed quality reduction, carry penalties of their own. Owners who set prices deliberately in October, from verified unit economics, are better positioned than those who defer the decision to a more comfortable moment that the cost environment is unlikely to supply.
