Barbershop input evidence register
43 financial inputs with their assumptions, calculation bases and cited sources.
Read the supported claim, observation period, geography and units together. A source access date records when it was consulted. A model assumption identifies a selected amount or target; a calculated result follows from those inputs and does not establish observed demand or a quoted opening budget.

These notes explain the opening budget, annual forecast and calculator assumptions. Linked sources provide the support described in each note; they do not necessarily confirm the selected amounts. Check scenario assumptions against local quotes and operating records.
- Model assumption
Applies to: Total opening budget · Lower opening budget · Upper opening budget · Leasehold improvements, plumbing and electrical · Permits, deposits, professional fees and insurance · Pre-opening payroll, recruiting and launch · Working capital reserve
StartFigures selected the complete opening range, leasehold allowance, permits and deposits, pre-opening cost and reserve for one fixed-location case. SBA supports separating one-time costs, monthly expenses and early cash; CBRE and TDLR provide premises and regulatory context. None supplies these dollar amounts. Replace them with the lease, authority fees, project schedule and dated cash plan.
- Model assumption
Applies to: Four chairs, stations, wash and sanitation equipment · POS, tools, opening supplies and retail inventory
Current vendor listings establish examples of individual chairs, one station and appointment software; Texas provides one equipment-rule example. StartFigures authored the larger equipment, installation, tools, POS, supplies and inventory allowances. Quantity, freight, tax, plumbing, electrical work, commissioning, warranty and local requirements remain unquoted.
- Model assumption
Applies to: Revenue (Years 1–5) · Consumables, card fees and retail cost (Years 1–5) · Paid owner and staff incl. employer costs (Years 1–5) · Occupancy and other operating costs (Years 1–5)
Every annual value is an authored scenario. Year-three revenue is exactly 27 completed visits × $45 × 6 days × 52 weeks. Sales-linked costs use the selected 9% envelope. Payroll and overhead are schedules informed by national occupation, employer-tax, rent and processor context; none verifies this location's sales or expenses. Refunds and discounts reduce net sales once; the 9% cost allowance covers consumables, processing and retail cost rather than deducting those sales adjustments again.
- Model assumption
Applies to: Net sales per completed visit (base scenario) · Net sales per completed visit (lower sensitivity) · Net sales per completed visit (upper sensitivity) · Completed client visits per day (base scenario) · Completed client visits per day (lower sensitivity) · Completed client visits per day (upper sensitivity) · Trading days per week (base scenario) · Trading days per week (lower sensitivity) · Trading days per week (upper sensitivity) · Opening sales as a share of mature volume · Monthly increase toward mature volume · Forecast horizon (months)
The visit value, daily volume, schedule, ranges and ramp are StartFigures planning inputs. Classification, establishment counts, occupation data, appointment features and product architecture do not establish one shop's price, throughput, completion rate or launch curve. Validate them with a local menu, chair-time test and retained POS sales.
- Model assumption
Applies to: Monthly fixed operating costs · Contribution margin
The $26,000 mature monthly fixed-cost input equals year-three payroll and occupancy/other costs divided by 12. The 91% contribution margin is one minus the selected 9% sales-linked cost envelope. Published context identifies costs to validate but does not verify either selected input.
