What the numbers represent
Startup capital includes opening commitments and a working capital reserve. Revenue and income-statement expenses are annual amounts in whole U.S. dollars. Monthly fixed costs belong to a separate operating sensitivity. Year 3 defines the mature comparison year.
Source context and modeled inputs
Primary sources include public agencies such as BLS and SBA. Industry sources include associations and original surveys. Vendor sources include equipment suppliers and operating guides. Prefer primary evidence when comparable figures conflict; explain differences in scope before comparing values.
Every numeric input has an evidence-register entry. A source link alone does not verify a forecast: entries marked Model assumption identify author-selected budgets, capacity targets and future growth. Exact supplier-derived values are labeled separately. Source access dates document when a reference was checked.
The opening and operating scenarios
Low and high capital estimates describe different premises, equipment condition and reserve requirements. They are not confidence intervals. Price and throughput bounds are sensitivity cases; local demand, capacity and staffing need independent validation.
How operating break-even is calculated
Monthly sales equal average transaction value × daily transactions × operating days per week × 4.33. Break-even sales equal monthly fixed costs ÷ contribution margin. The opening ramp increases sales toward mature capacity; the first month that covers fixed costs is the reported operating break-even month.
The same formula runs for the displayed base result and interactive calculator. It holds fixed costs and contribution margin constant. Changing a price may change real demand or cost percentages; the simplified calculator does not predict those effects.
EBITDA, owner income and payback
EBITDA subtracts cost of sales, payroll and operating overhead from revenue. It excludes financing, income tax, depreciation and amortization. Working-owner labor belongs in payroll. Distributions depend on debt service, working capital, replacement spending and taxes. Operating break-even is not startup-investment payback.
The approved reference case
The Bakery case preserves the capital schedule, annual P&L and calculator inputs in the supplied Bakery C Chart-led mockup. The transaction calculator and annual forecast are independently specified and use slightly different rounding. Source context does not turn those approved illustrative values into measured national averages.
How Business Scores differ from financial results
The five-component Business Score is an editorial assessment of a defined operating scope. Its weighted total does not measure the probability of success. Each component has its own rationale, evidence basis and assessment date. Catalog ranks compare completed assessments under the same rubric; an unassessed case is excluded.

Review and accountability
Inspect the evidence and limitations attached to each case. Source context, authored assumptions and editorial judgments have different roles. The editorial standards explain the review process, and the site profile describes its scope and accountability. Use the correction guidance to identify a specific statement and supporting evidence.
Before committing capital
Replace allowances with current equipment quotations, a lease proposal, a staffing roster and local demand observations. Test seasonality and slower collections in a monthly cash forecast. Keep a dated record of changes and their evidence.
