| Technology Infrastructure, $15,000/month |
Fixed |
Carry as monthly overhead from Month 1 through Month 60. It must be covered before the model reaches operating break-even. |
Treating platform spend as fully usage-based and understating the base burn. |
| Regulatory & Compliance, $8,000/month |
Fixed |
Keep in fixed overhead because it runs every month across the forecast period, regardless of near-term account volume. |
Delaying compliance expense until revenue scales, which makes early losses look too low. |
| Office Rent, $3,000/month |
Fixed |
Include as a stable monthly charge when calculating the revenue needed to reach Month 30 break-even. |
Linking rent to assets or customers when the model treats it as a flat facility expense. |
| Core leadership and advisory payroll |
Fixed |
Model CEO / Founder, Head of Engineering, Senior Financial Advisor, and Marketing Manager as recurring payroll capacity already planned from the first year. |
Excluding founder and core team salaries from break-even, which hides true operating burn. |
| Third-Party Service Fees, 8.0% in Year 1 |
Variable |
Apply as a percentage tied to activity volume. The rate declines to 5.0% by Year 5, improving contribution as scale builds. |
Treating service fees as fixed overhead instead of a drag on each dollar of revenue. |
| Customer Acquisition Costs, 10.0% in Year 1 |
Variable |
Model as revenue-linked acquisition spend, falling to 7.0% by Year 5. This directly affects how much revenue converts into contribution. |
Locking acquisition spend as a monthly budget and missing the pressure from faster growth. |
| Cloud hosting over base capacity |
Semi-variable |
Keep the base platform charge in fixed overhead, then add usage-driven hosting as accounts, sessions, and data processing rise. |
Putting all cloud spend in fixed overhead and missing margin compression during volume spikes. |
| Compliance Officer and support hires |
Semi-fixed |
Add step changes when capacity is hired: Compliance Officer starts Month 13 at $110,000 annual salary, and Customer Support Specialist starts Month 25 at $60,000. |
Smoothing headcount evenly across all months instead of showing the payroll step-up when the team expands. |
