Break-Even Revenue Calculator for Construction Companies
What Is Break-Even Revenue?
Break-even revenue is the minimum amount of work you need to complete and bill in a year just to cover all of your costs. Below that number you are losing money. Above it you are generating profit.
Most contractors have a gut feel for whether they are busy enough, but few know their actual break-even number. Without it you cannot answer basic questions like: do we need to add another crew to be profitable this year, or how much does our revenue need to grow to support a new piece of equipment?
Knowing your break-even number gives you a floor. Everything above it is profit territory. Everything below it is a loss.
The Formula
Break-Even Revenue = Total Fixed Costs / Gross Profit Margin %
Definitions
Total fixed costs are the costs your business incurs regardless of how much work you do. This includes all overhead: office rent, admin salaries, owner compensation, insurance, vehicles, utilities, and professional fees. If you have already calculated your overhead burden rate, your total annual overhead is this number.
Gross profit margin is the percentage of each revenue dollar left after paying your direct job costs — labor, materials, subcontractors, and equipment. If you bring in $1,000,000 in revenue and your direct job costs are $750,000, your gross profit is $250,000 and your gross profit margin is 25%.
A Worked Example
A mechanical contractor has the following financials:
Total annual overhead (fixed costs): $480,000
Annual revenue: $3,200,000
Direct job costs (labor, materials, subs): $2,400,000
Gross profit: $800,000
Gross profit margin: $800,000 / $3,200,000 = 25%
Break-Even Revenue = $480,000 / 25% = $1,920,000
This contractor needs to complete and bill $1,920,000 in work just to break even. Every dollar above that generates 25 cents of profit toward the bottom line.
What to Do With This Number
Compare your break-even revenue to your current backlog and projected annual volume. If your backlog covers your break-even with room to spare, you are in good shape. If you are consistently running close to break-even, you have either a volume problem or a margin problem, and you need to figure out which one.
A low gross profit margin pushes your break-even number up, meaning you need more revenue to cover the same overhead. Improving job margins even by a few percentage points can dramatically lower your break-even threshold.
The Relationship Between Overhead and Break-Even
Every dollar of overhead you add raises your break-even revenue requirement. A contractor adding a $60,000 office manager with a 25% gross margin needs to generate an additional $240,000 in revenue just to pay for that hire. Understanding this relationship helps you make smarter decisions about when to add overhead and how much new revenue you need to justify it.
