Make the assumptions
visible.
This prototype demonstrates how an estimate should be explained. Its financial inputs are invented, and its scoring proposal has not been calibrated.
Four layers of information.
- Source fact
A specific observation, with source, geography, period and definition. A government homepage alone does not support a dollar estimate.
- Format assumption
A chosen operating setup: premises, capacity, opening days, paid team, customer segment and sales unit.
- Calculation
A reproducible transformation that connects inputs to revenue, profit, cash and financing need.
- Decision explanation
What is technically feasible, what is sensitive and which missing evidence might change the conclusion.
One consistent financial chain.
Revenue = units × net selling price
EBITDA = revenue − variable costs − fixed cash OPEX
EBIT = EBITDA − depreciation
Project NCF = EBITDA − ΔNWC − subsequent CapEx
Reserve = minimum cash buffer + peak cumulative NCF deficit
Startup funding = pre-opening uses U₀ + reserve
Project payback = first stable crossing of −U₀ + cumulative NCF
Each required role is paid in the managed fixture. Payroll is included once in OPEX, and depreciation once in EBIT. Opening inventory and deposits are cash uses, not duplicate first-month expenses. A reserve funds losses already present in NCF; it is not subtracted again for project payback.
All public demo outputs are before financing and income taxes. This does not mean actual taxes are zero. Operating costs include unresearched allowances; a real model needs a local roster, operating tax applicability, asset schedules and payment terms.
For the simplified 60-month example, immediate settlement and stable noncash operating balances imply assumed ΔNWC = 0. There is no debt or owner-distribution schedule. Ramp-up is explicit; seasonality, inflation and growth are held neutral. The annual result is a sum of months, not a mature month multiplied by 12.
Two axes, two different decisions.
| Axis | What changes | What it means |
|---|---|---|
| Lean / Base / Premium | Space, seats, paid team, capacity and equipment | Different launch formats, not statistical ranges |
| Downside / Central / Upside | Demand, food cost share and ramp-up | Conditions for the same selected format, not success probabilities |
Scores have separate purposes.
Business Idea Score compares national Base formats: capital access 20%, EBIT margin 25%, cash resilience 15%, demand trend 20%, operating complexity 20%.
State Fit compares one business format across states: demand/supply 30%, operating basket 25%, entry cost without reserve 20%, mandatory procedural critical path 15%, staff availability 10%. Scores for different ideas in Texas are not a universal idea ranking.
The scores are not combined, do not measure probability of success and do not move with a user’s financial slider. Missing factors remain missing; weights are not reassigned.
N⁻ = 100 − N⁺
Total = sum of normalized factor × fixed weight
Proposed bounds L/U are the 10th/90th percentiles of a fixed comparable sample, not the current filter. U=L yields a disclosed neutral 50. A proposed 80% registry coverage threshold still does not guarantee representativeness. Overlap, correlation, calibration and sensitivity to weights must be reviewed before scoring.
Synthetic scoring example — not a rating of Restaurant or Texas
The following invented normalized factors illustrate contributions only.
Illustration A · Business Idea
| Factor | N / 100 | Weight | Contribution |
|---|---|---|---|
| Capital access | 65 | 20% | 13.0 |
| EBIT margin | 72 | 25% | 18.0 |
| Cash resilience | 48 | 15% | 7.2 |
| Demand trend | 55 | 20% | 11.0 |
| Operating simplicity | 40 | 20% | 8.0 |
| Synthetic total | 100% | 57.2 |
Illustration B · State Fit
| Factor | N / 100 | Weight | Contribution |
|---|---|---|---|
| Demand / supply | 60 | 30% | 18.00 |
| Operating basket | 55 | 25% | 13.75 |
| Entry cost, no reserve | 70 | 20% | 14.00 |
| Required procedures | 40 | 15% | 6.00 |
| Staff availability | 65 | 10% | 6.50 |
| Synthetic total | 100% | 58.25 |
Data quality controls publication.
Financial evidence and State Fit evidence are assessed independently. A quality score describes inputs; it is not business attractiveness.
| Component / weight | 0 | 0.5 | 1 |
|---|---|---|---|
| Authority / 30% | No identifiable accountable source | Identified secondary source with method | Responsible primary authority or documented direct supplier evidence |
| Directness / 25% | No relevant match | Proxy with disclosed adjustment | Matching metric, geography and format |
| Freshness / 20% | Date missing or unusably old | Older input with justified adjustment | Within a predefined metric-specific freshness window |
| Corroboration / 15% | Unresolved conflicting evidence | Single usable observation | Independent agreement or a sufficient primary series |
| Traceability / 10% | No reproducible origin | Partial citation or transformation | Exact source, period, definition and reproducible transformation |
Proposed component rubric for this design. Metric-specific freshness windows and input materiality must be fixed before operational use.
- DQ ≥ 80: publish estimates only with all critical inputs, each critical input quality q ≥ 0.6 and successful checks. Scores and ranks additionally need suitable calibration.
- DQ 60–79: preliminary ranges and limitations; no final score or rank.
- DQ < 60 or a critical missing input: supported facts and missing evidence only; hide dependent financial estimates.
The synthetic demonstration is clearly separated from a researched release. Its primary states are Not scored / Not assessed.
Commercial disclosure.
This prototype promotes the Restaurant Financial Model from FinModelsLab as a possible next step after understanding the free example. Its seller describes editable forecasts, scenarios, a dashboard and financial statements. The actual workbook has not been audited here.
No automatic import of the demo assumptions, researched Texas inputs or guaranteed outcome is promised. The purchase card shows the verified USD price and workbook format. Shopify checkout shows the final total and applicable purchase terms. Scores are independent of product availability and price.
Source roles and dates.
SBA business planning supports planning context and separation of startup and recurring costs. It is not the source of the financial fixtures.
Texas DSHS retail food establishments supports the health-department lookup route. It does not establish approval requirements for a specific restaurant address.
Links checked 05 September 2026. Prototype date: 05 September 2026. There is no financial price observation period because the inputs were authored. No competitor figures are used.
