The base case produces $742,140 in first-year sales and $4,639 in EBITDA after the paid owner allowance. Year 1 cash changes by −$64,445 after working capital and scheduled debt. First-year EBITDA is positive in this case, but it is not spendable owner cash. Debt principal and working-capital investment still have to be funded; the closing-cash rows show their effect.
Build sales from the operating unit
Sales equal completed project-equivalents multiplied by the assumed realized contract value. The cap is derived from in-house labor-hours per project and available productive crew time. The same contract value can produce different profit when material choices, site access or subcontract prices change.
The forecast should be supported by a lead-to-estimate-to-contract pipeline, but inquiries are not booked revenue. Keep signed work, quoted work and unqualified leads separate. Check who supplies long-lead items and whether the promised start date is compatible with their delivery. The model’s average workload is a framework for that review, not an asserted local pipeline.

From revenue to operating profit
Materials and specialist subcontractors are costed per project-equivalent. The employed crew and working owner are paid on a recurring schedule, including time that cannot be billed. Travel, estimating, snagging, procurement and customer coordination therefore consume the productive-hour allowance.
Use job costing to detect whether the quoted labor-hours or materials scope were wrong. A markup on purchased materials is not the same as a gross margin on sales. Unexpected work should be documented and priced before execution where appropriate, rather than assumed to be recoverable after the fact.

| Closing cash | $20,555 | $96,315 | $172,075 |
EBITDA excludes depreciation, interest and income taxes. Profit before tax includes depreciation and interest; it excludes debt principal. Cash also reflects inventory, receivables and principal repayments. The model assumes no supplier credit or customer deposits.
What happens when demand changes
Demand scenarios alter the number of completed project-equivalents. They retain the same contract mix and employed crew, and cannot exceed the available labor-hour ceiling. They do not assume that lower volume immediately permits laying off skilled staff or reducing insurance. A separate late-payment stress shows the extra receivables funding created by slower collection at the mature sales level.
The lower case uses 80.0% of base demand and the higher case 115.0%. These are sensitivity cases, not probability estimates. A negative cash balance is an unfunded requirement and would require intervention; the model does not assume access to an overdraft.
| Case | Year 1 sales | Year 1 EBITDA | Year 1 closing cash | 60-month minimum cash |
|---|---|---|---|---|
| Lower demand | $593,712 | −$56,373 | −$27,129 | −$38,988 |
| Base demand | $742,140 | $4,639 | $20,555 | $13,819 |
| Higher demand | $853,461 | $50,397 | $56,317 | $30,874 |
When the opening investment is recovered
The first modeled recovery of opening project funding occurs in month 43. This is project recovery before financing, not an equity distribution schedule.
Recovery depends on collected project contribution after the standing crew and overhead, not merely on the value of signed contracts. Unbilled work and receivables are still funding uses. The cumulative calculation includes working-capital movements but excludes income tax, major vehicle replacements and exit proceeds. Do not finance a vehicle on the assumption that resale proceeds will fill an operating shortfall.
Owner pay and remaining business cash
The owner is assumed to work in production and management and receives a recurring salary allowance. If the owner instead handles sales and supervision full time, remove their production hours from crew capacity or add a replacement employee. Keeping the owner’s hours in capacity after removing the owner from the site overstates the number of jobs the business can finish.
Owner base compensation is $6,500 per month; the budget also includes the employer-burden allowance. Additional owner distributions are zero. The mature monthly cash surplus after scheduled debt, before taxes and incremental working capital, is $6,313. This mature point is different from the opening-year result.
Read the result before adopting the forecast
The base first-year operating result (EBITDA) is $4,639. The lowest modeled cash balance is $13,819, compared with the opening reserve of $85,000. The difference, $71,181.08, shows reserve consumed by the lowest point in the modeled horizon; it is not an additional equipment expense or a loan repayment estimate.
Compare owned tools and a used van with a larger fleet purchase. Budget customer deposit timing, supplier payments, retentions and overlap between jobs before sizing working capital.
Owner compensation is included. The same opening funding applies across the published demand scenarios. A higher installed procurement cost needs more funding or less opening cash and a rerun of the forecast. Compare the monthly cash exhibit and scenario period rather than inferring opening-year affordability from a mature-month margin.
