Why Did My Sales Go Up but My Profit Go Down?

The short answer. Because growth changes your cost structure faster than your P&L reports it. Revenue climbs while gross margin percent slips from discounting and low-margin work, labor gets hired ahead of productivity, overhead steps up, and working capital absorbs the cash. Sales are a lagging scoreboard. Gross margin dollars against fixed obligation tell you what growth is really doing.

The Math on a Real Growth Year

Here is the pattern in numbers. A distributor goes from $3.0 million to $3.9 million in revenue. Thirty percent growth. The owner tells everyone it was the best year in the company's history.

Gross margin slides from 38 percent to 33 percent. Some of that is a big new account won at a thin price. Some is freight the business absorbed to keep the new account happy. Gross margin dollars still rise, from $1.14 million to about $1.29 million. Up roughly $147,000.

Overhead climbs from $820,000 to $1.02 million. A second warehouse lead, an inside sales hire, a bigger lease, more insurance. Up $200,000.

Operating profit goes from $320,000 to about $267,000. Down $53,000 on $900,000 of new revenue. The best year in company history made less money than the year before it.

Where Profit Goes When Sales Climb

• Margin mix. New revenue rarely arrives at the same margin as the old book. Big accounts negotiate. Rush work gets underpriced. The blend drops a few points and every dollar of the old book is now diluted.
• Discounting to win. Volume bought with price is the most expensive volume there is. A 5 point discount on a 35 percent margin job gives away one seventh of the gross margin on that work.
• Labor ahead of productivity. New hires cost full wages on day one and produce at full speed months later. Labor productivity utilization drops while the payroll line grows.
• Overhead step-ups. Fixed cost does not rise smoothly. It jumps. One more manager, one more truck, one more lease. Each step raises breakeven before the revenue to cover it shows up.
• Working capital. More volume means more cash tied up in receivables, inventory, and jobs in progress. On a 60-day operating cycle, every $100,000 of added annual operating cost ties up about $16,400 in Working Capital Required.

Why the P&L Hides It Until Year-End

Monthly statements arrive late and report the blend. Revenue up looks like good news, so nobody digs into margin by customer or by job. The overhead additions each look reasonable on their own. The cash squeeze gets blamed on timing.

By the time the year-end statement shows profit down, the cost structure has been locked in for twelve months. That is the cost of running a business on lagging indicators. You find out what growth did after it already did it.

What to Read Instead

Track gross margin dollars, not revenue, against total fixed monthly obligation: overhead plus debt service. That is fixed obligation coverage. If revenue rises and coverage falls, growth is consuming the business.

Before any hire, lease, or big new account, run it through Layer Cake. Restate Fixed Cost Capacity, restate Required Gross Margin dollars, and see whether the new breakeven still clears at the margin the new work will actually deliver. If it does not, the growth has to be repriced or declined.
