Definition
Investing cash flow captures cash used for or generated from long-term investments (capex, acquisitions, asset sales).
Example
Buying $250k of servers shows as -$250k investing cash flow for the period.
How to use it
- Treat large capex as a runway event; it can shorten runway even if operating metrics are stable.
- Separate maintenance capex from growth capex for clearer planning.
- Review investing cash flow when planning hiring or marketing ramps.
- Track asset sales separately from operating performance to avoid noise.
Common mistakes
- Classifying operating expenses as investing cash flow to smooth burn.
- Ignoring one-time asset sales that temporarily inflate cash.
- Assuming investing cash flow is always negative (asset sales can reverse it).
Why this matters
This term matters because cash timing and risk are usually the difference between a plan that works on paper and a plan that survives. Use consistent definitions so decisions are comparable over time.
Practical checklist
- Write a 1-line definition for "Investing Cash Flow" that your team will use consistently.
- Keep the time window consistent (weekly/monthly/quarterly) when comparing trends.
- Segment results (channel/plan/cohort) before drawing big conclusions from blended averages.
- Use a calculator that references this term (e.g., Investment Decision Calculator) to sanity-check assumptions.
- Read the related guide (e.g., Runway and burn: gross vs net burn, working capital, and cash levers) for context and common pitfalls.
