Make the calculation match the financial decision

Planning tools turn assumptions into a decision model. Revenue and profit forecasts describe a possible operating path, cash-flow forecasting adds timing, and budget variance compares actual performance with the plan. Capital-budgeting tools evaluate whether a defined investment creates enough value for its cost and risk.

A forecast should expose uncertainty rather than conceal it. Sensitivity analysis changes one driver at a time; scenario analysis changes a coherent group of assumptions. Together they show which inputs matter, what can break the plan, and where management attention has the greatest value.

Build a forecast that supports a decision

Step 1
Start with operational drivers
Express revenue through customers, volume, price, retention, or capacity and express costs through the activities that create them. Driver-based assumptions are easier to challenge than a single growth percentage.
Step 2
Connect profit to cash and capital
Add payment timing, working-capital needs, startup or project outlays, financing, and taxes where relevant. A profitable plan can still run out of cash.
Step 3
Create decision boundaries
Test downside, base, and upside cases, then vary the most uncertain drivers. Define what result would trigger a delay, redesign, or stop decision.

Keep forecasts useful and falsifiable

Document the source, owner, and date for material assumptions. A forecast that cannot be updated or compared with actuals quickly becomes a narrative instead of a control tool.
Avoid false precision in distant periods. Use ranges and scenario probabilities where appropriate, and increase detail for the near-term period that management can influence.
Customer acquisition cost and lifetime value must use compatible customer definitions, contribution measures, and time horizons before their ratio is meaningful.

Frequently asked questions

What is the difference between sensitivity and scenario analysis?

Sensitivity analysis changes one input while holding others constant. Scenario analysis changes several connected assumptions to represent a plausible operating state such as downside, base, or upside.

Should a forecast start with revenue or cash?

Start with operational revenue and cost drivers, then translate them into the timing of cash receipts and payments. Both views are needed because profit and cash answer different questions.

Which capital-budgeting result should control a decision?

NPV directly measures value above a required return, while IRR, payback, and profitability index provide additional perspectives. Use a stated decision policy and examine assumptions and constraints before relying on one metric.
