Prioritize Your Next Move with a Runway Forecast

Stop guessing what to do next. Use a simple runway forecast to focus your effort on the highest-impact decision for your product.

Who This Helps

This is for Product Managers who feel stuck between a dozen good ideas. You know you need to prioritize, but everything feels urgent. The Founder Finance Basics Mission Pack gives you the tools to cut through the noise. It helps you turn product questions into measurable, confident decisions.

Mini Case

Ben’s team had revenue growth, but cash was flat. He had three possible next moves: launch a new feature, double down on a marketing channel, or hire a new engineer. Each one felt right. By building a quick runway forecast, he saw his cash would only support 5 months at the current burn. That number made the decision clear: the new feature could wait. He focused on optimizing the existing marketing channel first, which improved his payback period by 22 days. The runway number gave him the focus he needed.

Do This Now (5 Steps)

  1. Grab your last three months of bank statements and your current cash balance.
  2. Calculate your average monthly cash burn (money going out).
  3. Divide your current cash by that monthly burn. That’s your runway in months.
  4. Write that number on a sticky note and put it on your monitor. Seriously, do it.
  5. Review your top three product ideas. Ask: "Which one directly improves this number or protects it?"

Avoid These Traps

  • Chasing Shiny Objects: Don't prioritize a cool new tech stack if it doesn't affect your core economics or extend your runway.
  • Analysis Paralysis: Your first forecast doesn't need to be perfect. A good-enough number today is better than a perfect number next week.
  • Ignoring Payback: If you spend on growth, know when you expect to earn it back. A long payback period eats runway fast.
  • Mixing Personal & Business: Keep business cash separate. Blurred lines lead to inaccurate, scary forecasts.
  • Forgetting to Re-forecast: Update your runway number every month. It’s a living thing.
  • Optimizing for Vanity Metrics: More users is great, but not if your cost to acquire them is unsustainable.
  • Letting Emotion Drive Pricing: Use a model, like the Pricing Scenario Guardrails mission suggests, to test changes safely.
  • Hiring on a Hope: Always stress-test new hires against your runway. A new salary changes your burn rate instantly.

Your Win by Friday

By Friday, you will have one clear number: your runway. You’ll use it to kill one low-impact meeting or project. You’ll redirect that effort toward the single experiment most likely to improve your cash position. You’ll stop feeling scattered and start leading with focus. You’ve got this.
