OVERHEAD RATE

WHY YOUR CONSTRUCTION OVERHEAD RATE KEEPS CHANGING.

QUICK ANSWER

An overhead rate that changes significantly from year to year is telling you something. Either revenue is fluctuating while fixed costs stay constant, which is normal, or fixed costs are creeping up faster than revenue, which is a structural problem. In practice there are four causes: revenue movement against flat fixed costs, incremental fixed cost creep nobody recalculated for, owner salary that changed or was never included, and a rate calculated a different way each year.

The number that hurts is the rate you're still bidding with. Overhead is fixed costs divided by revenue, so a 20 percent revenue drop raises the rate 25 percent without a single new expense. Meanwhile a hire in January, a software subscription in March, and a truck in July each add cost that no bid rate was updated for. By December you're pricing work with a number that was right eleven months ago. Recalculating once a year catches most of it, and recalculating when a big item changes catches the rest.

THE DEFINITION

WHAT IT MEANS.

Overhead rate is fixed costs divided by revenue.

FOUR CAUSES

WHY THE RATE WILL NOT SIT STILL.

01

Revenue fluctuates but fixed costs don't

Overhead rate is fixed costs divided by revenue. When revenue drops 20 percent and fixed costs stay constant, the overhead rate increases by 25 percent automatically. A contractor doing $4M one year and $3.2M the next with the same overhead structure went from a 14 percent rate to 17.5 percent without changing anything about their cost structure.

02

Fixed cost creep from new hires, software, and vehicles

Fixed costs grow incrementally. A new hire in January, a software subscription in March, a new company vehicle in July: each one adds to overhead and none of them triggered a bid rate recalculation. By December, overhead has grown by $85,000 and every bid submitted since January was underpriced by the corresponding percentage of that creep.

03

Owner salary changed, or was never in there

Owner salary is the single most commonly missing or misrepresented overhead line item. When the owner takes draws instead of a defined salary, the overhead rate is understated by the difference between the draw amount and market rate compensation, which runs $120K to $180K for most $2M to $8M owner operators. The bid rate inherits that understatement on every job it prices.

04

The rate is calculated a different way each year

If the overhead rate is calculated differently each year, with different line items included or excluded and workers comp in one year and out the next, the rate will fluctuate without any underlying change in the business. That movement is a measurement problem rather than a cost problem. Fixing it means writing the method down once and using the same method every year.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

Revenue drops, the rate climbs

A contractor doing $4M one year and $3.2M the next, with the same overhead structure, went from a 14 percent overhead rate to 17.5 percent. Nothing about the cost structure changed. A 20 percent revenue drop against constant fixed costs raises the rate by 25 percent on its own.

What a year of creep costs

A hire in January, a subscription in March, and a vehicle in July add up to $85,000 of new overhead by December. Every bid submitted since January was underpriced by the corresponding percentage of that creep. None of it was visible in a single month, because each piece looked small on its own.

Owner compensation, at market

Market rate owner compensation for most $2M to $8M owner operators runs $120K to $180K. When the owner takes draws instead, the overhead rate is understated by the difference between the draw and that market rate. The bid rate is then wrong by the same amount on every job.

HOW SPM FIXES IT

HOW THE RATE STAYS PUT.

Recalculate annually, and again when a big item changes

The rate gets recalculated formally once a year. It also gets recalculated any time a significant overhead item changes: a new hire, a lease, a major software change, or an office move. That's what keeps the bid rate current instead of eleven months stale.

One method, written down, used every year

The line items included in the calculation get decided once and documented, so workers comp is either in the rate every year or out of it every year. A rate that moves for measurement reasons can't be trusted at bid time. Consistency is what makes a year over year comparison mean something.

Overhead rate is one of the 10 rolling CEO Report metrics

The rate is tracked monthly against the trailing twelve month actual and against the bid rate being applied to current estimates. When those two numbers separate, the bid rate gets corrected before the next round of bids goes out. Seeing both side by side every month is what makes the correction happen on time.

COMMON QUESTIONS

FREQUENTLY ASKED.

Formally once a year. Recalculate again any time a significant overhead item changes: a new hire, a lease, a major software change, or an office move. Waiting for the annual cycle after a big hire means months of bids priced with the old number.
Use the annual average for bidding. Seasonal revenue swings are real, and using a peak season rate understates overhead in the slow months. The annual average recovers overhead across the whole year, which is the period the overhead is incurred over.
Yes. Overhead rate is one of the 10 rolling metrics in the monthly CEO Report. The rate is tracked against the trailing 12 month actual and against the bid rate being applied to current estimates, so a divergence between the two is visible the month it starts.
