| CEO/Founder payroll |
Fixed |
Treat the $150,000 annual salary as recurring monthly overhead during the planning range. |
Leaving founder payroll out makes Month 31 break-even look easier than it is. |
| Office Rent |
Fixed |
Use $2,500 per month from Month 1 through Month 60 in the fixed overhead base. |
Spreading rent by user count hides the cash burn before scale. |
| Legal & Accounting |
Fixed |
Include $1,500 per month as fixed operating overhead, not as a launch-only item. |
Treating recurring compliance work as one-time understates monthly break-even needs. |
| Cloud Hosting & API Fees |
Variable |
Model as a revenue-linked charge: 8.0% in the first year, falling to 6.0% by the fifth year. |
Using a flat hosting dollar amount misses usage growth as paid subscribers rise. |
| Data Licensing Fees |
Variable |
Apply the revenue percentage: 5.0% in the first year, improving to 3.0% by the fifth year. |
Ignoring data fees overstates gross margin on subscription revenue. |
| Payment Processing Fees |
Variable |
Use 2.5% of revenue in the first two years, then reduce to 2.2% by the fifth year. |
Modeling this as 25% instead of 2.5% would crush contribution margin by error, not economics. |
| Customer Support |
Semi-variable |
Combine the revenue-linked support charge of 3.0% in the first year with support staffing that rises from 1.0 to 3.0 FTE. |
Counting only payroll misses ticket volume tied to subscriber growth. |
| Marketing Manager and acquisition budget |
Semi-fixed |
Treat the manager role and annual marketing plan as planned capacity steps, including the $150,000 first-year budget tied to CAC assumptions. |
Treating the first-year marketing budget as optional breaks the acquisition math. |
