Who This Helps
This is for founder-operators who feel that nagging worry about cash. You know revenue is coming in, but you're not sure how long your money will last. The Founder Finance Basics Mission Pack helps you move from gut-feel panic to calm, evidence-based decisions.
Mini Case
Ben's SaaS company had $180k in the bank and was burning $30k a month. He thought he had 6 months of runway. After building his Runway Forecast Card, he saw his true net burn was $38k when he accounted for a delayed enterprise deal. His real runway was under 5 months. This one-page truth gave him the clarity to delay a non-critical hire and extend his runway by 3 weeks.
Do This Now (5 Steps)
- Grab your last three months of bank statements and your P&L.
- Calculate your average monthly net burn (cash out minus cash in).
- List every known future cash event for the next quarter (big invoices, tax payments, payroll bumps).
- Divide your current cash balance by your adjusted monthly burn rate. That's your core runway number.
- Write that number at the top of a single page, with the three biggest factors that could change it below. Seriously, one page only.
Avoid These Traps
- Mixing personal and business finances. It blurs the real picture. Keep them separate.
- Using only the revenue number from your accounting software. It often doesn't match when cash actually hits your account.
- Forgetting quarterly or annual bills. That insurance payment in month 4 will sneak up on you.
- Being overly optimistic with "best-case" sales pipelines. Use committed deals only for your safe forecast.
- Not updating the forecast every single month. Runway is a moving target.
- Getting lost in a giant, complex spreadsheet. If you can't explain it in 60 seconds, it's too complex.
- Ignoring the impact of a new hire. Factor in their full cost (salary, benefits, tools) from day one.
- Letting the number paralyze you. The forecast is a tool for action, not for fear.
