Financial Forecasting

Definition

Financial forecasting is the process of estimating future revenue, expenses, and cash flow based on what's happened in the past, what's happening now, and what you plan to change. It's not fortune-telling — it's informed projection.

A good forecast combines historical patterns (seasonal trends, growth rates) with known upcoming changes (a new hire starting next month, a contract expiring in Q3, a price increase in April).

Why It Matters

Without a forecast, every financial decision is reactive. You find out you can't afford something after you've committed to it. A forecast lets you see problems 3-6 months out, when you still have time to adjust.

The value isn't in being exactly right — it's in being directionally correct. If your forecast says you'll hit a cash crunch in August, you can start building a buffer in May. If it shows you'll have excess cash in Q4, you can plan investments instead of scrambling to deploy capital at year-end.

Forecasting also forces discipline. When you commit a revenue number for next quarter, you have something to measure against. The gap between forecast and actual tells you where your assumptions are wrong, which makes the next forecast better.

Example: A SaaS company forecasts $150K MRR by June based on current growth rate plus two enterprise deals in the pipeline. They also forecast a $40K/month cost increase from a new engineering hire. The forecast shows they'll need the enterprise deals to close to maintain positive free cash flow. That changes how aggressively they pursue those deals.

Types of Forecasts

• Revenue forecast: Projecting future sales based on pipeline, seasonality, and growth trends
• Expense forecast: Estimating future costs including planned hires, contracts, and variable costs
• Cash flow forecast: Combining revenue and expense timing to predict bank balance over time
• Burn rate forecast: Projecting how spending will evolve and when you'll need more capital
