Financial Performance
Week 10 of University of Melbourne MGMT30006 covers how ventures measure and project financial performance: the pro-forma Profit & Loss statement required in the group business plan, top-down versus bottom-up modelling, break-even and cash burn/runway, startup metrics (CAC payback, LTV, churn), and the main categories and purpose of financial ratios. The exam FAQ confirms ratio formulas need not be memorised — so the emphasis is on reading and interpreting numbers, not calculating ratios. CAC payback is a confirmed numeric exam archetype, and the pro-forma P&L is a required part of the group report.
What this chapter covers
- 01Financial basics — price − costs = profit; using TAM/SAM/SOM to estimate near-future revenue
- 02Pro-forma model (3–5 years) — top-down / discovery-driven (target → reverse P&L → key assumptions) vs bottom-up (unit economics up); surfacing implicit assumptions
- 03Modelling steps — forecast period, P&L, balance sheet, cash-flow statement; deriving the annual funding gap
- 04P&L ≠ cash flow; the cash-flow cycle and working-capital management; the Cash Machine model
- 05Break-even analysis — Fixed Costs = (Price − Variable Cost) × Units; break-even units = FC ÷ unit contribution margin; the feasibility reality-check
- 06Cash burn & runway — net burn = out − in; runway = cash ÷ burn (months until cash runs out)
- 07Startup metrics — revenue run rate, MRR, CAC, CAC payback = CAC ÷ MRR-per-customer, LTV, LTV/CAC, ARPU, churn; unit economics
- 08Financial-ratio categories (liquidity, profitability, activity, leverage) — know the category and purpose, NOT the memorised formula (per the exam FAQ)
Calculate and interpret CAC payback
- +1State the formula: CAC payback (months) = CAC per customer ÷ monthly revenue per customer (MRR per customer). This is the number of months of subscription revenue needed to recover the acquisition cost.
- +1Substitute and solve: 36 ÷ 4 = 9 months to pay back the cost of acquiring a customer.
- +1Evaluate against benchmarks: 9 months is moderate — better than a slow 12–24-month payback but short of the best-in-class under-6-months for consumer subscriptions. It is workable only if customers stay well beyond 9 months, so retention/churn is the binding risk.
- +1Recommend one justified action: cut CAC (e.g. shift spend to lower-cost content/referral channels) to shorten payback, OR raise the monthly price if demand allows — either directly reduces the ratio. Because the app only profits after month 9, improving retention is the highest-leverage complementary move, but the question asks payback specifically, so the primary lever is CAC or price.
Key terms
- Pro-forma P&L
- A projected Profit & Loss statement (usually 3–5 years) built from explicit assumptions — required in the group business plan. It can be built top-down (start from a revenue target and work back to 'what must be true') or bottom-up (start from unit price/cost and build volumes up).
- Break-even analysis
- The volume or price at which revenue equals total cost: Fixed Costs = (Price − Variable Cost) × Units, so break-even units = Fixed Costs ÷ unit contribution margin. Its real purpose is a feasibility reality-check — is that required volume achievable? — not the arithmetic itself.
- Cash burn & runway
- Net burn rate = monthly cash outflows − inflows; cash runway = current cash ÷ monthly burn = the number of months until the money runs out. Monitoring runway signals when a venture must raise capital.
- CAC payback
- The months needed to recover the cost of acquiring a customer: CAC per customer ÷ monthly revenue per customer (MRR). A break-even metric that the subject treats as more telling than an oversimplified LTV/CAC ratio; shorter is better.
- P&L vs cash flow
- Profit is not cash: revenue is not the same as cash received (credit sales), cash out is not the same as cost (capital expenditure, working-capital build), and the timing of cash flows differs from accounting dates — which is why a profitable venture can still run out of cash.
- Financial-ratio categories
- Four families that read a firm's health: liquidity (can it meet short-term obligations), profitability (margins and returns), activity/efficiency (how well assets are used) and leverage (reliance on debt). Per the exam FAQ, know the category and purpose — you are not expected to memorise the formulas.
Financial Performance FAQ
Do I need to memorise financial-ratio formulas for the exam?
No. The subject's FAQ is explicit that you are not expected to memorise the financial-ratio formulas — you need to know the main categories (liquidity, profitability, activity, leverage) and what each tells a founder. The examinable skill is reading and interpreting numbers and knowing which category answers a given question, not reproducing a formula from memory. This is also why the subject sets has-math to false.
What is the difference between top-down and bottom-up modelling?
Top-down (discovery-driven planning) starts from a financial objective — say a revenue target in year five — and works backward into a 'reverse P&L', identifying the assumptions that would have to be true and then validating them. Bottom-up starts from the unit price and cost of a single product, builds up customer numbers and uptake from the SOM, then layers in costs to reach a margin and break-even. The group report's pro-forma P&L can use either, but must surface its implicit assumptions.
Why can a profitable startup still run out of cash?
Because profit is an accounting measure and cash is not the same thing. Revenue booked on credit is not cash in hand, capital expenditure and working-capital increases are cash out that is not counted as cost, and the timing of cash flows differs from accounting dates. That is why the subject stresses cash-flow projection, burn rate and runway alongside the P&L, and why rapid growth can cause a cash shortage.
Can AI help me build a pro-forma and check metrics?
Yes, as a study aid. Sia can walk you through a top-down or bottom-up P&L, check a break-even or CAC-payback calculation and its interpretation, and drill the ratio categories. Use it to rehearse the method and verify your working; it does not do your graded report or exam, and University of Melbourne integrity rules apply — confirm details on Canvas.
Exam move
This is the numeric week, but the marks live in interpretation, so pair every calculation with a judgement. Drill the three core calculations until they are automatic and always add the interpretive sentence: break-even units = fixed costs ÷ unit contribution (then 'is that volume feasible?'), CAC payback = CAC ÷ monthly revenue per customer (then evaluate against benchmarks and recommend an action), and cash runway = cash ÷ burn (then 'when must we raise?'). Practise building a pro-forma P&L both top-down and bottom-up, always surfacing implicit assumptions. For ratios, learn the four categories and their purpose rather than memorising formulas — the FAQ confirms formulas are not examinable to memorise. Keep the P&L-is-not-cash-flow point ready to explain why a profitable firm can still fail. Because the pro-forma P&L is required in the group report, build one for your own venture now. When a metric interpretation stalls, ask Sia to benchmark it and suggest the lever. Confirm the exam date and format on Canvas and the University of Melbourne exam timetable.
