Production Planning and Cost Control

Chapter Introduction

Production planning and cost control are essential skills for any Red Seal-certified artisan baker. In a competitive business environment, the ability to produce precise quantities of baked goods while controlling ingredient, labour, and overhead costs determines business profitability. This chapter covers the fundamental principles of production planning, cost calculation methods, yield analysis, and loss control strategies — knowledge directly assessed on the Red Seal exam.

The Foundations of Production Planning

Definition and Objectives

Production planning is the process of determining the quantities of products to manufacture over a given period, based on forecast demand, production capacity, and available resources. Its main objectives are:

Minimizing surpluses and stockouts

Optimizing the use of labour and equipment

Reducing losses of perishable ingredients

Ensuring the freshness of products delivered to customers

Factors Influencing Planning

Several factors must be considered when developing a production plan:

Factor	Impact on Production
Seasonality	Increased demand for certain products (e.g., panettone at Christmas, croissants at breakfast)
Days of the week	Production peak on Thursday and Friday for weekends
Weather conditions	Reduced sales of glazed products in cold weather
Local events	Festivals, public markets, special orders
Equipment capacity	Deck oven limited to X loaves per cycle
Shelf life	Fresh products (24–48 h) vs. frozen products (weeks)

Demand Forecasting

Forecasting relies on the analysis of historical sales data. For each product, you must calculate:

Average daily sales = Total sales over a period ÷ Number of days in the period

Standard deviation = √(Σ(xᵢ − μ)² ÷ N)

where xᵢ represents each sales value, μ the mean, and N the number of days.

A prudent production plan uses the formula:

Quantity to produce = Average sales + (1.5 × Standard deviation)

This safety margin covers approximately 93% of normal demand fluctuations.

Calculating Yields and Losses

Dough Yield

Dough yield is the ratio between the final dough weight and the total weight of ingredients. It is expressed as a percentage:

Yield (%) = (Final dough weight ÷ Total ingredient weight) × 100

For example, if you mix 10 kg of ingredients and obtain 9.4 kg of dough, the yield is 94%. The 6% loss comes from water evaporation during mixing, dough adhering to the bowl walls, and flour lost during weighing.

Baking Yield

Baking yield measures the weight loss due to water evaporation in the oven:

Baking yield (%) = (Baked product weight ÷ Raw dough weight) × 100

Typical values are:

Product	Baking Yield
Country bread	85–88%
Baguette	80–85%
Croissant	88–92%
Sponge cake	92–95%
Dry biscuits	95–98%

Overall Yield

Overall yield combines both losses:

Overall yield (%) = Dough yield × Baking yield

Example: Dough yield = 94%, baking yield = 86%

Overall yield = 0.94 × 0.86 = 0.8084 = 80.84%

This means that to produce 100 kg of baked bread, you must weigh approximately 123.7 kg of ingredients (100 ÷ 0.8084).

Cost Calculation

Ingredient Cost

Ingredient cost is calculated from the standardized recipe. For each ingredient:

Ingredient cost = (Quantity used ÷ Quantity purchased) × Purchase price

Example: You purchase flour in 20 kg bags at $24.00. A recipe uses 5 kg of flour.

Cost = (5 ÷ 20) × 24.00 = $6.00

Unit Cost per Portion

To determine the cost of a finished product:

Unit cost = Total ingredient cost ÷ Number of portions produced

Suppose a croissant dough recipe costs $18.50 in ingredients and produces 40 croissants:

Unit cost = 18.50 ÷ 40 = $0.4625/croissant

Labour Cost

Labour cost includes wages, benefits (approximately 15–20% of gross salary), and employer contributions. To calculate the labour cost per product:

Labour cost per product = (Total production time × Loaded hourly rate) ÷ Number of products

The loaded hourly rate is calculated as follows:

Loaded hourly rate = Base hourly rate × 1.18 (for 18% in contributions)

If a baker earns $22.00/hour and contributions represent 18%, the loaded rate is 22.00 × 1.18 = $25.96/hour.

Full Cost Price

Full cost price (or total cost) includes:

57.Ingredient cost

58.Direct labour cost

59.Manufacturing overheads (electricity, gas, rent, equipment depreciation, insurance)

Full cost price = Ingredient cost + Labour cost + Overheads

Overheads are often allocated as a percentage of labour cost or an hourly oven usage rate.

Profit Margin and Selling Price

Gross profit margin = Selling price − Full cost price

Margin rate (%) = (Profit margin ÷ Selling price) × 100

Recommended selling price = Full cost price ÷ (1 − Desired margin rate)

Example: Full cost = $1.20, desired margin = 40%

Selling price = 1.20 ÷ (1 − 0.40) = 1.20 ÷ 0.60 = $2.00

Managing Losses and Waste

Sources of Losses

Losses in a bakery fall into three categories:

Category	Examples	Reduction Possible
Production losses	Dough stuck to bowl, burnt products, deformations	Yes — standardized procedures
Inventory losses	Expired ingredients, infestation, theft	Yes — FIFO rotation, inventory
Sales losses	Unsold products discarded	Partially — better forecasting

The FIFO Method

FIFO rotation (First In, First Out) is mandatory to guarantee freshness and minimize losses. Ingredients received first must be used first. This method is particularly critical for:

Dairy products (butter, cream, milk)

Liquid or powdered eggs

Fresh yeast

Fruits and fruit purées

Calculating the Loss Percentage

Loss rate (%) = (Weight of lost products ÷ Total weight produced) × 100

A loss rate above 5% for fresh bakery products generally indicates a planning or quality control problem.

Purchase Planning

Calculating Order Quantities

To determine the quantity of ingredients to order:

Quantity to order = (Production requirement + Safety stock) − Available stock

Safety stock covers delivery lead times and demand variations. It is calculated:

Safety stock = (Average daily consumption × Delivery lead time in days) × Safety factor

The safety factor is generally 1.5 for critical ingredients and 1.0 for slow-moving ingredients.

Purchase Calculation Example

A bakery consumes 25 kg of flour per day. The supplier's delivery lead time is 3 days. Current stock is 60 kg. Safety stock is set at 1.5 × daily consumption × lead time.

Safety stock = 1.5 × 25 × 3 = 112.5 kg

Requirement for 7 days of production = 25 × 7 = 175 kg

Quantity to order = (175 + 112.5) − 60 = 227.5 kg

Purchase Specifications

Purchase specifications precisely describe the characteristics of the ingredients to be ordered:

Type of flour (durum wheat, soft wheat, whole wheat) and extraction rate

Protein content (e.g., 12–13% for bread)

Sugar granulation

Butter melting point

Organic or fair-trade certification if required

Cost Control in Production

The Standardized Recipe

The standardized recipe is a control document that specifies:

Exact ingredients with precise weights (in grams or kilograms)

Ingredient temperatures

Mixing time and speed

Fermentation and baking temperatures

Raw and baked piece weights

Expected yield

Any deviation from the standardized recipe must be documented and analyzed.

Variance Analysis

Variance analysis compares actual production to planned production:

Quantity variance = Actual quantity used − Standard quantity expected

Cost variance = (Actual cost − Standard cost) × Actual quantity

An unfavourable (negative) variance indicates a loss of control. Possible causes include:

Weighing errors

Lower-quality ingredients with reduced yield

Poorly calibrated equipment

Untrained personnel

Standard Cost and Actual Cost

Standard cost is the theoretical cost calculated from the standardized recipe and standard purchase prices. Actual cost is the cost actually incurred. The difference between the two constitutes the overall variance.

Overall variance = Actual cost − Standard cost

An overall variance greater than 3% must trigger an investigation.

Production Management and Planning Tools

The Production Schedule

The production schedule organizes manufacturing by product, quantity, start time, end time, and equipment used. An effective schedule:

Staggers products according to their fermentation time

Groups products baking at the same temperature

Plans cleanings between productions

Allows for cooling times before packaging

Batch Planning

Batch planning involves producing large quantities of products with a long shelf life (dry biscuits, frozen breads) to reduce setup costs. Calculating the economic batch:

Economic batch = √(2 × Annual demand × Setup cost ÷ Unit holding cost)

This formula minimizes the total production and holding cost.

Oven Scheduling

To optimize oven usage, group products according to their baking temperature:

Baking Temperature	Typical Products
160–180 °C	Cakes, fruit tarts
180–200 °C	Croissants, sandwich loaves
200–220 °C	Baguettes, country breads
220–240 °C	Rustic breads, fougasses

Each temperature change requires a stabilization time of 10 to 15 minutes, representing a loss of productivity. Plan bakes in ascending temperature order to minimize adjustments.

Performance Indicators

Control Ratios

Bakeries use several ratios to evaluate their performance:

Ingredient cost / sales ratio: Generally between 25% and 35% for an artisan bakery.

Labour / sales ratio: Generally between 25% and 35%.

Overhead / sales ratio: Generally between 15% and 25%.

Loss / production ratio: Must be below 5%.

The Break-Even Point

The break-even point is the production level where revenues equal total costs:

Break-even point (in units) = Fixed costs ÷ (Unit selling price − Unit variable cost)

Example: Monthly fixed costs = $12,000, average selling price = $3.00, unit variable cost = $1.50

Break-even point = 12,000 ÷ (3.00 − 1.50) = 12,000 ÷ 1.50 = 8,000 units/month

Below 8,000 units, the bakery loses money; above that, it makes a profit.

Managing Special Orders

Calculating Prices for Special Orders

Special orders (wedding cakes, custom orders) require a separate price calculation:

154.Cost of specific ingredients

155.Estimated work hours × loaded hourly rate

156.Equipment usage (oven, cold room)

157.Design and consultation fees

158.Additional profit margin for risk

The Quote

The quote must include:

Detailed description of the product

Weight and dimensions

Delivery date and transport conditions

Total price and payment terms (often 50% deposit)

Cancellation conditions

Traceability and Recall Management

The Importance of Traceability

Traceability allows you to track each production batch from ingredient purchase to consumer sale. It is mandatory for:

Quickly identifying the source of contamination

Removing non-compliant products from the market

Meeting the requirements of the Canadian Food Inspection Agency (CFIA)

The Lot System

Each production batch must carry a unique identifier including:

Production date

Recipe number

Lot number of main ingredients

Equipment used

Name of the responsible baker

Summary

Production planning and cost control rest on five pillars:

181.Accurate demand forecasting: use historical data and statistical formulas (mean + standard deviation) to determine production quantities.

182.Rigorous yield calculation: know the dough and baking yields for each product to convert finished product requirements into ingredient quantities.

183.Cost mastery: systematically calculate ingredient costs, loaded labour, and overheads to establish profitable selling prices.

184.Loss management: maintain a loss rate below 5% through FIFO rotation, standardized recipes, and variance analysis.

185.Continuous control: use performance ratios (ingredient cost/sales, labour/sales) and the break-even point to evaluate the financial health of the business.

The standardized recipe is the central tool of all control: it sets the standards for quality, yield, and cost. Any deviation must be documented and corrected.

Pitfalls to Avoid

188.Confusing dough yield and baking yield: the former concerns loss during mixing, the latter during baking. The overall yield is the product of both.

189.Forgetting payroll contributions in labour costs: the loaded hourly rate includes approximately 15–20% in contributions on top of the base salary.

190.Using the purchase price instead of the unit cost per portion: for a recipe, the cost of each ingredient must be proportional to the quantity actually used.

191.Neglecting safety stock in purchase orders: ordering only the net requirement without a safety margin exposes you to stockouts.

192.Calculating the selling price by adding a percentage to the cost: the correct formula is Price = Cost ÷ (1 − Desired margin), not Price = Cost × (1 + Margin).

193.Ignoring production losses when calculating quantities: if the overall yield is 85%, producing 100 kg of bread requires 117.6 kg of ingredients, not 100 kg.

194.Planning production without considering oven capacity: check the number of pieces per batch and the baking time before setting quantities.

195.Not documenting variances: a 2% cost variance may seem minor, but on an annual revenue of $500,000, it represents a $10,000 loss.

196.Forgetting seasonality in forecasts: average annual data masks seasonal peaks; use monthly or weekly data.

197.Confusing gross margin and margin rate: gross margin is a dollar amount; margin rate is a percentage of the selling price. A 40% margin rate means the cost represents 60% of the selling price.
