Nail Salon 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 work, plumbing, electrical, ventilation and finishes · Permits, design, deposits, recruiting, training and launch · Working capital reserve
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
Applies to: Six pedicure spas, six manicure stations and installed equipment · Tools, task lighting, sanitation equipment and opening supplies · POS, furnishings, signage and security
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
Applies to: Revenue (Years 1–5) · Nail products, disposables, 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 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
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, 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
Applies to: Monthly fixed operating costs · Contribution margin
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.
