This recipe produces a month-by-month personal financial plan that determines exactly how much runway you have, what minimum salary you need, and when (or whether) to transition from side-project to full-time founding. The output is a spreadsheet-based cash flow model with three scenarios (conservative, baseline, optimistic) and an explicit set of transition trigger criteria.
The plan covers 5 steps: (1) Expense Audit and Categorization dividing spending into essential and reducible categories using 6 months of actual bank data, (2) Runway Calculation across three scenarios (conservative, baseline, optimistic) with specific monthly burn rates, (3) Founder Salary Planning using 2025-2026 benchmark data by funding stage, (4) Full-Time Transition Decision Framework with explicit financial, validation, and opportunity triggers, and (5) Cash Flow Projection building a 24-month month-by-month model with milestone markers and contingency actions.
| Quality Metric | Minimum | Good | Excellent |
|---|---|---|---|
| Expense data source | Self-estimates | 3 months statements | 6+ months statements |
| Scenarios modeled | 1 (baseline) | 2 (baseline + conservative) | 3 scenarios |
| Runway length (conservative) | 12 months | 18 months | 24+ months |
| Transition criteria | Vague goals | Measurable triggers | Triggers + dates + metrics |
| Partner alignment | Not discussed | Discussed informally | Written agreement |
Wrong: Using optimistic scenario as the planning basis. Founders overestimate revenue speed and underestimate fundraising time. [src3]
Correct: Plan on conservative scenario, celebrate if optimistic materializes.
Wrong: Taking $0 salary indefinitely, draining personal savings completely. This creates desperation leading to bad decisions. [src7]
Correct: Pay yourself a sustainability salary. Even at pre-seed, plan for minimum living expenses.
