What does cash flow forecast mean?
A cash-flow forecast estimates when cash will enter and leave a business over a future period.
A practical example
Begin with a clearly defined reporting period and list the amounts or events included in the measure. Reconcile the result to the relevant cash-flow, income-statement or balance-sheet line before comparing it with another period or business.
How to analyze it
- Name the measure.
State the exact definition and period. - Trace the inputs.
Identify the source statement, schedule or transaction for each figure. - Reconcile the result.
Check that subtotals connect to the appropriate statement or cash balance. - Compare consistently.
Use the same definition for every period or company in the comparison.
When should you use cash flow forecast?
Use it to identify funding gaps, payment timing and liquidity needs before they occur.
Limitations and common mistakes
Forecast accuracy depends on collections, payment behavior and assumptions that should be updated with actuals.
Do not mix annual figures with monthly figures, ending balances with averages, or percentages with whole numbers. Record the definition used so another person can reproduce the result.
