A linked reference can support scope without confirming an exact forecast. Assumption entries identify values that still require local validation. Each field path identifies an input in the common business record.
- Model assumption
StartFigures selected the complete opening range, leasehold allowance, permits and deposits, launch cost and reserve for one fixed-location case. SBA supports cost categorization; CBRE and New York provide premises and regulatory context. None supplies these dollar amounts. Replace them with the lease, local authority fees, engineered plans, coordinated bids, project schedule and dated cash plan.

- Model assumption
Current vendor listings establish examples of individual furniture, ventilation components and appointment software. StartFigures authored the larger equipment, installation, tools, POS, sanitation, furnishings and opening-supply allowances. Quantity, freight, tax, plumbing, electrical work, ducting, commissioning, warranty and local approval remain unquoted.

- Model assumption
Every annual value is an authored scenario. Year-three revenue is exactly 36 completed visits × $55 × 6 days × 52 weeks. Cost of sales uses the selected 19% envelope. Payroll and overhead are schedules informed by occupation, employer-tax, rent and processor context; none verifies this location's sales or expenses.

- Model assumption
The visit value, daily volume, schedule, ranges and ramp are StartFigures planning inputs. Classification, establishment counts, occupation data, two local menus and appointment features do not establish this salon's service mix, price, throughput, completion rate or launch curve. Validate them with a local menu, paid tests, time study and retained POS sales.

- Model assumption
The $39,833 mature monthly fixed-cost input is rounded from Year-three payroll plus occupancy and other cost divided by 12. The 81% contribution margin is one minus the selected 19% sales-linked cost envelope. Published context identifies costs to validate but does not verify either selected input.
