Concrete Contractor Break Even — Frequently Asked Questions

Most concrete contractors break even at 8—12 jobs per month, but this varies widely by job size. A contractor doing large commercial pours ($10,000+/job) may only need 3—4 jobs. One doing smaller residential slabs and driveways ($2,000—$3,000/job) needs more volume. Enter your specific numbers above to find your actual break even point.
Key fixed costs for concrete contractors include equipment payments (mixer, screed, power trowel, saw), vehicle and trailer costs, insurance (general liability and equipment), tool maintenance, and phone/admin. Expect $4,500—$7,000/month in fixed costs as an independent operator. Equipment financing is often the largest single line item.
Use this calculator: enter your monthly fixed costs, your average variable cost per job (concrete, rebar, rental equipment), and your average job value. The contribution margin per job (job value minus variable costs) divided into your fixed costs gives your break even job count. Round up — you need to cover the full month's fixed costs.
Hiring an employee typically adds $3,500—$5,500/month in fixed labor costs (wages, payroll taxes, workers comp). This raises your break even by 1—2 additional jobs per month. However, a second worker usually increases your daily output by 40—60%, letting you take on more jobs. Use the Employee Cost Calculator to model the full cost before hiring.
Most new concrete businesses reach monthly break even within 3—6 months, assuming they already have equipment (owned or financed) and a client pipeline. The first 90 days are typically the hardest due to slow client acquisition. Building referral relationships with general contractors and landscapers early dramatically shortens the ramp-up period.
