14.2 Business Fundamentals: Costs, Pricing & Inventory
Key Takeaways
- Fixed costs (rent, insurance, equipment, wages) do not change with service volume; variable costs (product, utilities, supplies) rise and fall with how busy the salon is.
- Service pricing is built from cost-plus or margin targets; retail pricing often uses keystone (2× cost) as a baseline, adjusted for market and brand.
- Inventory par level is the minimum stock to keep on hand; reorder point triggers a new order before stock falls below par.
- FIFO (first-in-first-out) stock rotation uses the oldest stock first to prevent expired product being sold or used on clients.
- Compensation models — hourly, commission, booth rental, salon suite — differ in who bears the business risk and who controls the schedule.
Why a Stylist Needs Business Fundamentals
A Red Seal hairstylist is not only a technical practitioner but also a contributor to a business. MWA H Task H-19 (business fundamentals) makes up roughly 35% of the Salon Operations block — fewer questions than the front desk, but the math is direct and gettable. Expect at least one markup or discount calculation and at least one inventory or compensation scenario.
Business Costs: Fixed vs Variable
Every salon has two broad cost categories. Understanding the difference is the foundation of pricing and budgeting.
| Cost Type | Definition | Salon Examples |
|---|---|---|
| Fixed costs | Do not change with service volume in the short term | Rent or lease, business insurance, equipment financing, base wages, software subscriptions, licensing fees |
| Variable costs | Rise and fall with how busy the salon is | Colour and lightener product used per service, utilities (water, electricity for hot tools), towels and disposables, credit-card processing fees, commission paid per service |
A salon with high fixed costs must keep chairs full to break even; a booth-rental model pushes fixed costs down by transferring them to individual stylists.
Pricing Services and Retail
Service Pricing
Service prices are built to cover costs plus a profit margin. Two common methods:
- Cost-plus pricing — total the cost of the products and the time, then add a markup. Example: a colour service uses $12 of product and 90 minutes of stylist time; cost-plus adds a set margin (say 60%) to arrive at the service price.
- Target-margin pricing — start from the desired gross margin and back into the price. If the salon wants a 70% gross margin on a $12 product cost, the price is calculated as cost ÷ (1 − margin) = 12 ÷ 0.30 = $40.
Retail Pricing and Keystone
For retail products (shampoo, conditioner, styling aids), a common baseline is keystone — doubling the wholesale cost to set the retail price. A product that costs the salon $8 wholesale is keystone-priced at $16. Keystone is a starting point; premium brands may be priced above keystone and promotional items below.
Basic Business Math the Exam Tests
Worked examples:
- Markup: A salon buys a retail conditioner for $6 wholesale and sells it for $15. The markup in dollars is $15 − $6 = $9. The markup percentage on cost is $9 ÷ $6 = 1.5 = 150% markup on cost. The margin percentage on selling price is $9 ÷ $15 = 0.60 = 60% margin.
- Discount: A $80 service is discounted 20% for a loyalty promotion. Discount = $80 × 0.20 = $16. Discounted price = $80 − $16 = $64.
- Service revenue allocation: A client pays $150 total for a $110 colour service and $40 of retail product. Service revenue = $110; retail revenue = $40; total = $150. If a 10% commission is paid to the stylist on services only, commission = $110 × 0.10 = $11 (not $15).

Inventory Management
Salon inventory — colour, developer, retail products, disposables — ties up cash and can spoil. Four core concepts:
Par Level
The par level is the minimum quantity of each item the salon wants to keep on hand to avoid running out between deliveries. If par for a popular colour tube is 12 and the count drops to 12, it is time to order. Par is set based on usage rate and supplier lead time.
Reorder Point
The reorder point is the stock level at which a new order is placed, calculated so the new shipment arrives before stock falls below par. If you use 4 tubes a week, the supplier takes 1 week to deliver, and par is 6, the reorder point is par + (usage × lead time) = 6 + (4 × 1) = 10. When stock drops to 10, order.
FIFO Stock Rotation
First-in-first-out (FIFO) means the oldest stock is placed at the front and used first. New deliveries go to the back. This prevents product from sitting until it expires — a particular concern for oxidative colour and developer, which have a shelf life. Expired product used on a client is both a quality failure and a liability.
Tracking Usage and Shrinkage
- Usage tracking: the POS or inventory system records each product used per service so the salon can calculate real product cost per service and reorder accurately.
- Shrinkage is inventory loss from theft, spillage, miscounting, or unrecorded use. Shrinkage is controlled through restricted access to the colour room, regular counts, locked retail displays, and reconciliation of used product against service records.
| Term | Definition | Example |
|---|---|---|
| Par level | Minimum on-hand quantity to avoid stocking out | 12 tubes of a popular colour |
| Reorder point | Stock level that triggers an order | 10 tubes (par + usage during lead time) |
| FIFO | Oldest stock used first | New colour goes to the back of the shelf |
| Shrinkage | Inventory loss from theft, spillage, or error | 3% of retail inventory missing at count |
Compensation Models
A stylist's pay structure shapes their risk, control, and earning ceiling. The exam tests the tradeoffs.
| Model | How It Works | Stylist Risk | Control |
|---|---|---|---|
| Hourly wage | Fixed pay per hour worked, regardless of services performed | Low (stable income) | Low (employer sets schedule and prices) |
| Commission % | Stylist earns a percentage of services they perform (often 40–55%) plus possible retail commission | Medium (income rises and falls with bookings) | Medium (build your own clientele) |
| Booth rental (independent contractor) | Stylist pays a fixed weekly or monthly rent to the salon and keeps 100% of service revenue | High (pays rent even on slow weeks) | High (sets own hours, prices, products) |
| Salon suite | Stylist leases a private suite, runs an independent business | High (carries all overhead) | Highest (fully independent brand) |
Commission vs Rental Tradeoffs
- Commission suits newer stylists building a clientele: the salon provides marketing, front desk, products, and equipment, and the stylist gets a steady if smaller share of each service.
- Booth rental / suite suits established stylists with a full book: the stylist keeps all revenue after rent but pays their own products, insurance, taxes, and time off. A slow week still means rent is due.
The exam may frame a scenario where a stylist is choosing between models; the right answer depends on clientele size, risk tolerance, and how much control the stylist wants.
A salon buys a styling spray for $5 wholesale and sells it for $15 retail. What is the markup percentage on cost?
A salon uses 6 tubes of a colour per week. The supplier delivers in 1 week. Par level is 8 tubes. What is the reorder point?
Which inventory practice prevents expired oxidative colour from being used on a client?
A stylist with an established, fully booked clientele is choosing between a 50% commission role and a booth rental at $400/week. Which tradeoff is most accurate?
