Why Revenue Projections Matter More Than You Think
Revenue projections serve two purposes: internal planning (how much can we hire?) and external signaling (are we worth investing in?). Bad projections don't just mislead investors — they mislead you. And making hiring, spend, or product decisions based on inflated projections is how companies run out of runway unexpectedly.
Bottom-Up vs Top-Down Projection Methods
Top-Down (The Wrong Approach)
"The market is $10B and we'll capture 1% in 3 years = $100M." This is financially meaningless. It tells investors nothing about your actual business mechanics.
Bottom-Up (The Right Approach)
Start with your sales capacity and work forward:
- Outreach capacity: 50 leads/week contacted by your team
- Conversion rate: 3% close rate = 1.5 new customers/week
- Average contract value: $299/month
- Churn rate: 3%/month
- Month 12 projection: 72 cumulative customers × $290 (accounting for churn) = $20,880 MRR
This is what investors respect. Use the Revenue Projection Calculator to model your bottom-up forecast with your specific conversion rates and unit economics.
The 3-Scenario Revenue Model
Never present a single revenue projection. Present three:
- Conservative: 30% below your expected conversion rates. "If we underperform significantly."
- Base: Your actual expected trajectory. Supported by current conversion data.
- Optimistic: 30% above base. "If key assumptions prove better than expected."
Investors who see three scenarios with underlying assumptions trust you more than founders who present only a hockey stick. The Revenue Projection Calculator runs all three scenarios simultaneously.
What Your Revenue Projection Must Include
For investors: New customer acquisition rate, churn rate, expansion MRR from upsells, gross margin % at scale.
For internal planning: Break-even headcount, hiring timeline triggers, runway impact at each revenue milestone.
For yourself: Which single input has the most impact on the outcome? That is your #1 operational priority for the next 90 days.
