Most contractors don’t typically struggle because they can’t build. They struggle and often fail because they don’t know their break-even number and their pricing is below break-even margins. If you don’t know your break-even margin cold, you’re guessing on bids and pricing blind can be very costly.
Here’s how to calculate your break-even numbers:
Definition:
Your break-even is the point where your revenue equals your direct costs + overhead (Revenue = Direct Costs = Overhead). At this point, your profit equals zero.
An example of direct job costs (variable):
- Labor
- Materials
- Equipment
- Subcontractors
- Permits, specific to the job
An example of overhead (Fixed or semi-fixed):
- Office rent
- Administration costs
- Insurance
- Phones
- Trucks
- Accounting
- Owner base salary (yes, your salary is included)
Calculating your overhead percentage:
This is simple math. Overhead % = Overhead / Revenue.
Let’s say a contractor has an annual overhead of $750,000 and projected annual revenue of $300,000. $750,000 / $300,000 = 25%.
This means before job expenses, every job must carry 25% just to pay the overhead. If the bid is 20%, the loss is 5% on the job. What’s dangerous is that the repercussions aren’t felt until months later.
Calculating your target margin & aligning project bids to the margin:
If your break-even margin is 25% (the point where profit = 0), then it is realistic to set your target margin to 30% (minimum) to 35%+. The most stable contractors work on a 35-45% gross margin depending on risk, warranty exposure and project difficulty.
Pricing a project requires working backward from margin to price. Rather than “let’s add 20%” ask yourself what margin you require.
The calculation is:
Price = Cost / 1 – Target Margin. If your target margin is 35% and the job cost is $100,000: ($100,000 / 1 – .35) or $100,000 / .65. Your price to cover a 35% gross margin in this case is $153,846.
Resist the temptation to chase the low bidder:
Yes, there may be a need to “buy” a job to keep cash-flow running into the business but don’t make a practice of it. Sooner or later, bidding below the break-even margin is a downward spiral to insolvency.
A best practice is to support healthy margins by adding value in comparison to other lower bidding contractors:
- Offering superior product technologies
- Showing that products and installation are in line with proper building science
- Mastering a particular niche in the industry (shows mastery)
- Third-party validation (Mfr. certifications, case studies, industry associations, customer reviews)
- Overall professionalism (returning phone calls, clean & organized proposals, jobsite organization)
