Forecasting Business Viability

Overview

This sequence is explicitly based on textbook section 12.6 Forecasting. Across two sequential 60-minute lessons, Year 11 Business Studies students forecast revenue and costs, analyse break-even and cash flow, and use evidence to judge business viability. Contexts are fictional and Sydney-relevant, including school sports merchandise and student enterprises, with all amounts shown in Australian dollars.

Teacher note: The case businesses are fictional classroom scenarios and are not endorsements of particular products, services or business models.

Learning intentions

Lesson 1 — Forecasting total revenue and total cost: Students will:

• understand why businesses forecast
• define and distinguish total revenue, fixed costs, variable costs and total costs
• calculate TR = P × Q and TC = FC + VC
• explain how market research and sales history inform forecasts

Lesson 2 — Break-even analysis and cash flow projections: Students will:

• understand how break-even analysis supports business planning
• calculate break-even quantity using Q = FC ÷ (P − VC per unit)
• interpret profit or loss above and below break-even
• explain the purpose and components of a cash flow projection
• distinguish a cash flow projection from a cash flow statement

Success criteria

Lesson 1:

• I can accurately define total revenue, fixed costs, variable costs and total costs.

Lesson structure (two lessons of 60 minutes)

Lesson 1 — Forecasting total revenue and total cost (60 minutes)

1. 0–8 min · Retrieval starter. Students retrieve prior knowledge about revenue, costs, profit and business viability. They classify four quick examples as likely fixed or variable costs and explain one choice. Checkpoint: teacher samples responses and corrects the misconception that all regular costs are fixed.

2. 8–23 min · Explicit teaching and worked examples. Using textbook section 12.6, teach why businesses forecast and how market research and sales history inform expected sales. Model TR = P × Q and TC = FC + VC, clarifying that total variable cost is calculated from variable cost per unit × quantity. Model assumptions, such as expected quantity, stable price and estimated costs.

3. 23–43 min · Paired fictional Sydney SME task. Students analyse Blue and Gold Sports, a fictional student enterprise selling school sports merchandise. A hoodie sells for $45, expected sales are 80, variable cost is $25 per hoodie, and monthly fixed costs are $600 for design, setup and promotion. Students classify costs, calculate TR and TC, and identify what market research or sales history would make the forecast more reliable. Checkpoint: teacher checks formula choice, units and one written justification per pair.

4. 43–53 min · Interpretation and extension. Students discuss assumptions and limitations, including uncertain demand, unsold stock, changing supplier prices and seasonal sales. High-achieving students recalculate TR and TC if sales change to 60 or 100 hoodies and evaluate which assumption has the greatest effect.

5. 53–60 min · Individual exit ticket. Students define one key term, calculate TR and TC for a short new data set, classify one cost with justification, and identify one forecast limitation. Teacher answers: for the Blue and Gold Sports case, TR = $45 × 80 = $3,600; total variable cost = $25 × 80 = $2,000; TC = $600 + $2,000 = $2,600. A suitable limitation is uncertain demand or supplier prices.

Lesson 2 — Break-even analysis and cash flow projections (60 minutes)

1. 0–8 min · Retrieval and formula check. Students recall TR and TC, then complete a short break-even calculation. Review the difference between a cash flow projection, which forecasts future cash movements, and a cash flow statement, which records actual cash movements.

2. 8–23 min · Worked Better Rackets-style example. Adapt the example to Australian dollars: fictional Better Rackets sells a racquet for $120, has variable cost of $70 per racquet, and fixed costs of $5,000. Model Q = FC ÷ (P − VC per unit) = $5,000 ÷ ($120 − $70) = 100 racquets. Show that sales above 100 produce a contribution toward profit, while sales below 100 produce a loss, assuming the forecast conditions hold.

3. 23–35 min · Graph and interpretation task. Students graph or interpret total revenue and total cost lines, identify the break-even point, and explain the financial meaning of sales above and below it. Checkpoint: teacher asks students to explain why a higher fixed cost or lower contribution per unit raises break-even quantity. Extension: conduct sensitivity analysis for a $10 price reduction or $5 increase in variable cost and evaluate the assumptions.

4. 35–48 min · Isabella’s Sweets-style cash flow projection. Students complete a fictional Sydney student enterprise, Isabella’s Sweets, using a one-month projection: opening balance $500; cash inflows $2,400; cash outflows $2,100. They record opening balance, inflows, outflows, net flow and closing balance, then interpret whether the projected cash position supports viability. Teacher answers: net flow = $2,400 − $2,100 = $300; closing balance = $500 + $300 = $800. Students identify that positive cash flow does not by itself prove profitability.

5. 48–56 min · Exam-style case response. Students respond independently: calculate break-even, analyse the cash flow projection and recommend whether the enterprise should proceed. They must cite evidence and include one limitation, such as uncertain sales, timing of customer payments or changing input costs. Checkpoint: teacher uses the structure “calculation → interpretation → recommendation → limitation”.

6. 56–60 min · Reflection and exit ticket. Students state one difference between a cash flow projection and statement, interpret a result above or below break-even, and identify one assumption they would test before launching. Teacher collects responses for reteaching.

Differentiation

• Provide a formula bank showing TR = P × Q, TC = FC + VC, and Q = FC ÷ (P − VC per unit), with units and a worked first step.
• Provide a vocabulary table for forecast, total revenue, fixed cost, variable cost, total cost, contribution, break-even, inflow, outflow, net flow, projection and statement.
• Use partially completed calculations and tables for students requiring scaffolding; allow calculators and colour-coding of fixed/variable costs and inflows/outflows.
• Provide sentence starters: “The break-even point means…”, “Sales above break-even indicate…”, “The closing balance is…”, and “The recommendation is justified because…, although…”.
• Pair students strategically and use teacher checkpoints to address formula selection, calculation accuracy and interpretation.
• Extend the high-achieving cohort through sensitivity analysis of price, quantity, variable cost and fixed cost; evaluation of assumptions; comparison of alternative scenarios; and recommendations about which additional market research or sales-history evidence should be collected.
