Financial Projections

Create a comprehensive 3-5 year financial model with revenue projections, cost structure, headcount planning, cash flow analysis, and three-scenario modeling (conservative, base, optimistic) for startup financial planning and fundraising.

Use this skill when

  • Working on financial projections tasks or workflows
  • Needing guidance, best practices, or checklists for financial projections

Do not use this skill when

  • The task is unrelated to financial projections
  • You need a different domain or tool outside this scope

Instructions

  • Clarify goals, constraints, and required inputs.
  • Apply relevant best practices and validate outcomes.
  • Provide actionable steps and verification.
  • If detailed examples are required, open resources/implementation-playbook.md.

What This Command Does

This command builds a complete financial model including:

  1. Cohort-based revenue projections
  2. Detailed cost structure (COGS, S&M, R&D, G&A)
  3. Headcount planning by role
  4. Monthly cash flow analysis
  5. Key metrics (CAC, LTV, burn rate, runway)
  6. Three-scenario analysis

Instructions for Claude

When this command is invoked, follow these steps:

Step 1: Gather Model Inputs

Ask the user for essential information:

Business Model:

  • Revenue model (SaaS, marketplace, transaction, etc.)
  • Pricing structure (tiers, average price)
  • Target customer segments

Starting Point:

  • Current MRR/ARR (if any)
  • Current customer count
  • Current team size
  • Current cash balance

Growth Assumptions:

  • Expected monthly customer acquisition
  • Customer retention/churn rate
  • Average contract value (ACV)
  • Sales cycle length

Cost Assumptions:

  • Gross margin or COGS %
  • S&M budget or CAC target
  • Current burn rate (if applicable)

Funding:

  • Planned fundraising (amount, timing)
  • Pre/post-money valuation

Step 2: Activate startup-financial-modeling Skill

The startup-financial-modeling skill provides frameworks. Reference it for:

  • Revenue modeling approaches
  • Cost structure templates
  • Headcount planning guidance
  • Scenario analysis methods

Step 3: Build Revenue Model

Use Cohort-Based Approach:

For each month, track:

  1. New customers acquired
  2. Existing customers retained (apply churn)
  3. Revenue per cohort (customers × ARPU)
  4. Expansion revenue (upsells)

Formula:

MRR (Month N) = Σ across all cohorts:
  (Cohort Size × Retention Rate × ARPU) + Expansion

Project:

  • Monthly detail for Year 1-2
  • Quarterly detail for Year 3
  • Annual for Years 4-5

Step 4: Model Cost Structure

Break down operating expenses:

1. Cost of Goods Sold (COGS)

  • Hosting/infrastructure (% of revenue or fixed)
  • Payment processing (% of revenue)
  • Variable customer support
  • Third-party services

Target gross margin:

  • SaaS: 75-85%
  • Marketplace: 60-70%
  • E-commerce: 40-60%

2. Sales & Marketing (S&M)

  • Sales team compensation
  • Marketing programs
  • Tools and software
  • Target: 40-60% of revenue (early stage)

3. Research & Development (R&D)

  • Engineering team
  • Product management
  • Design
  • Target: 30-40% of revenue

4. General & Administrative (G&A)

  • Executive team
  • Finance, legal, HR
  • Office and facilities
  • Target: 15-25% of revenue

Step 5: Plan Headcount

Create role-by-role hiring plan:

Reference team-composition-analysis skill for:

  • Roles by stage
  • Compensation benchmarks
  • Hiring velocity assumptions

For each role:

  • Title and department
  • Start date (month/quarter)
  • Base salary
  • Fully-loaded cost (salary × 1.3-1.4)
  • Equity grant

Track departmental ratios:

  • Engineering: 40-50% of team
  • Sales & Marketing: 25-35%
  • G&A: 10-15%
  • Product/CS: 10-15%

Step 6: Calculate Cash Flow

Monthly cash flow projection:

Beginning Cash Balance
+ Cash Collected (revenue, consider payment terms)
- Operating Expenses
- CapEx
= Ending Cash Balance

Monthly Burn = Revenue - Expenses (if negative)
Runway = Cash Balance / Monthly Burn Rate

Include Funding Events:

  • Timing of raises
  • Amount raised
  • Use of proceeds
  • Impact on cash balance

Step 7: Compute Key Metrics

Calculate monthly/quarterly:

Unit Economics:

  • CAC (S&M spend / new customers)
  • LTV (ARPU × margin% / churn rate)
  • LTV:CAC ratio (target > 3.0)
  • CAC payback period (target < 18 months)

Efficiency Metrics:

  • Burn multiple (net burn / net new ARR) - target < 2.0
  • Magic number (net new ARR / S&M spend) - target > 0.5
  • Rule of 40 (growth% + margin%) - target > 40%

Cash Metrics:

  • Monthly burn rate
  • Runway in months
  • Cash efficiency

Step 8: Create Three Scenarios

Build conservative, base, and optimistic projections:

Conservative (P10):

  • New customers: -30% vs. base
  • Churn: +20% vs. base
  • Pricing: -15% vs. base
  • CAC: +25% vs. base

Base (P50):

  • Most likely assumptions
  • Primary planning scenario

Optimistic (P90):

  • New customers: +30% vs. base
  • Churn: -20% vs. base
  • Pricing: +15% vs. base
  • CAC: -25% vs. bas
