| Software | $300 |
| Freelancers | $1200 |
| Miscellaneous | $500 |
| Net Profit | $2000 |
This helps founders understand overall business performance.
Break-Even Analysis
Break-even analysis helps find the level of profitability attained by a new venture.
This is extremely important for bootstrapped businesses.
Break-Even Formula
Example
| Monthly Costs | Revenue Needed |
| $1000 | $1000 |
| $3000 | $3000 |
| $5000 | $5000 |
If revenue grows above expenses, profit begins.
Why Break-Even Matters
| Benefit | Explanation |

| Marketing | $200 | $250 | $300 |
| Software | $100 | $100 | $100 |
| Team Costs | $300 | $400 | $500 |

Simple financial projection templates help founders:
- Understand monthly performance
- Predict future expenses
- Plan business decisions
- Avoid cash shortages
