How to Create a 90-Day Financial Forecast (Without a CFO)

Advisory

If you’ve ever looked at your profit and loss report and thought, “Well, that’s interesting, but now what?”… you’re not alone.

Looking back on what happened last month or last quarter can help us understand where we’ve been. But it doesn’t tell us where we’re headed. That’s where forecasting comes in, and it’s one of the simplest ways to step into your CEO mindset and lead your business with clarity.

What Is Financial Forecasting?

Forecasting is simply predicting your future financial position based on what you know right now, including your expected income, expenses, and upcoming business plans.

It’s not about perfection. It’s about visibility.

A financial forecast helps you:

  • Anticipate income dips or slower months
  • Plan for team growth or launches
  • Make proactive (not reactive) decisions
  • Avoid cash flow panic
  • Build confidence in your CEO decisions

Start With a Simple 90-Day Forecast

You don’t need an accountant or CFO to get started. All you need is 30 minutes, some honest numbers, and a willingness to look ahead.

Here’s how I map out my own 90-day forecast:

1. Estimate Your Income

  • What do you already have booked?
  • What retainers or repeat clients are locked in?
  • Are there any upcoming launches or promotions?
    Use conservative estimates, aim for grounded, not wishful.

2. List Your Expenses

  • Fixed costs (software, subscriptions, wages)
  • Variable costs (marketing, contractors, upcoming projects)
  • Profit First transfers or tax set-asides

3. Add In Key Dates

  • Product launches
  • School holidays
  • Team hires
  • BAS deadlines or tax payments

This gives you a visual plan, not just a report. You can easily see where you might need to cut back, ramp up, or shift resources.

Use It to Navigate Growth or Dips

Your forecast becomes a practical decision-making tool. Here’s how I use mine:

  • Slow Season? I batch content ahead of time and reduce costs in advance.
  • Launch Coming Up? I plan team support, budget for ads, and set realistic income targets.
  • Hiring? I forecast onboarding costs and track how new income supports the expansion.
  • What-if Scenarios? I model income variations so I can make decisions calmly, not reactively.

The Key Shift: Forecasting = Leadership

Forecasting isn’t just a finance task, it’s a leadership tool. When you see what’s coming, you can lead with intention. You’re no longer surprised by dips or stuck in reactive mode.

Even a messy forecast is better than none. It builds your confidence and helps you feel in control.

Take Action This Week

Block out 30 minutes in your calendar. Open a spreadsheet or Google Doc and build a simple 90-day forecast, income, expenses, key dates, and potential decisions.

It doesn’t have to be fancy. It just needs to exist.

Because when you put money first, the rest really does follow.
