Plain definition
A forecast is the company’s best current estimate of a future financial result, based on evidence and stated assumptions. It is different from a budget or target: the forecast must show what is now likely to happen, even when that result is disappointing.
Illustrative example
Monetary examples use Saudi riyals (SAR). The same principles apply in other currencies.
A software company budgeted of April revenue. By mid-March it has signed , has of proposals at a 50% expected conversion rate, and expects of renewals from customers who have confirmed their intention to renew. Assume each amount relates to services expected to be delivered and recognised as revenue in April. The finance manager forecasts April revenue of : 260,000 + 60,000 + 80,000.
The forecast is below the budget. Sales can respond by pursuing the remaining proposals or bring forward a campaign, while the operations lead can delay discretionary contractor spend that had assumed the budgeted revenue.
A forecast is not a promise. Its value comes from making the evidence and uncertainty visible, then changing it when the evidence changes.
Why it matters
If management continues to present the budget as the outlook, it may commit cash and staffing for sales that are no longer probable. The useful question is not whether the team still wants ; it is what information would move the estimate and what decision must be made before April.
Practical consequence
Keep a dated forecast for the next planning periods and name the drivers behind it: signed orders, conversion rate, renewal rate, price, and collection timing. Ask the commercial owner to confirm the status of major opportunities, compare the prior forecast with actual results, and revise only the assumption that evidence has changed. A forecast cannot remove uncertainty; a downside case is needed when one customer or event could materially change the result.
