How to Build Financial Projections That Investors Actually Believe

Financial projections are one of the most scrutinized parts of any investor presentation. Get them right, and they demonstrate business acumen and market understanding. Get them wrong, and they destroy credibility and kill deal momentum.

This guide shows you how to build realistic, credible financial projections that stand up to investor scrutiny and support your fundraising narrative.

Why Financial Projections Matter

Investors know your projections won't be exactly right—that's not the point. They're evaluating whether you:

1. Understand your business model deeply
2. Know your unit economics and key drivers
3. Have realistic assumptions about growth and costs
4. Can think strategically about resource allocation
5. Understand the path to profitability and next funding round

Poor projections signal lack of business understanding, even if your product is strong.

The Three Core Components

Every financial projection includes three main components:

1. Revenue Model

Shows how you make money and how that grows over time.

Key Elements:

• Pricing structure
• Customer acquisition timeline
• Revenue per customer
• Growth rate assumptions
• Revenue recognition timing

2. Cost Structure

Shows what it costs to deliver your service and run your business.

Key Elements:

• Cost of goods sold (COGS)
• Sales and marketing expenses
• Research and development
• General and administrative costs
• Hiring plan

3. Key Metrics

Shows the underlying business health and efficiency.

Key Elements:

• Customer acquisition cost (CAC)
• Lifetime value (LTV)
• Gross margin
• Burn rate
• Runway

Before building projections, validate your business model assumptions to ensure realistic foundations.

Building Your Revenue Model

Step 1: Define Your Pricing Structure

Start with clear, well-justified pricing:

Example SaaS Pricing:

Starter Plan: $49/month
- Target: Individual users and freelancers
- Features: Basic functionality

Professional Plan: $199/month
- Target: Small teams (5-20 people)
- Features: Team collaboration + advanced features

Enterprise Plan: $999/month
- Target: Large organizations (50+ people)
- Features: Full platform + dedicated support

Validation Points:

• Have you validated willingness to pay at these prices?
• Are these prices competitive with alternatives?
• Do they support your target margins?

Step 2: Model Customer Acquisition

Project how many customers you'll acquire and when:

Early Stage Example (Months 1-12):

Month 1-3: Beta and Early Adopters
- 5 customers/month (founder-led sales)
- Average deal: $199/month
- Total: 15 customers, $2,985 MRR

Month 4-6: Initial Scaling
- 10 customers/month (first sales hire)
- Average deal: $250/month (mix of plans)
- Total: 30 new customers, $10,485 MRR total

Month 7-12: Early Traction
- 20 customers/month (2 sales reps)
- Average deal: $300/month
- Total: 120 new customers, $46,485 MRR

Key Assumptions to Document:

• Sales cycle length
• Conversion rates at each funnel stage
• Sales rep productivity ramp
• Seasonal factors

Step 3: Account for Churn

No projection is credible without churn assumptions:

Realistic Churn Rates:

Year 1: 5-7% monthly churn (early product, learning)
Year 2: 3-4% monthly churn (product-market fit)
Year 3+: 2-3% monthly churn (established product)

Monthly Revenue Impact:

Starting MRR: $50,000
New MRR: +$10,000
Churned MRR: -$2,500 (5% of base)
Ending MRR: $57,500
Net New MRR: $7,500

Step 4: Calculate Revenue

Combine acquisition and churn for realistic revenue projections:

Year 1 Example:

Month 1:
- Starting Customers: 10
- New Customers: 5
- Churned Customers: 0
- Ending Customers: 15
- MRR: $2,985

Month 12:
- Starting Customers: 138
- New Customers: 20
- Churned Customers: 7 (5% churn)
- Ending Customers: 151
- MRR: $45,300

Building Your Cost Structure

Step 1: Calculate Cost of Goods Sold (COGS)

These are direct costs to deliver your service:

SaaS COGS Example:

Infrastructure Costs:
- Cloud hosting: $0.50/customer/month
- Data storage: $0.25/customer/month
- CDN and bandwidth: $0.15/customer/month
- Third-party APIs: $0.30/customer/month

Support Costs:
- Support staff: 1 person per 200 customers
- Average cost per support person: $5,000/month

Year 1 COGS Projection:

Average Customers: 83
Infrastructure: $1,245/month
Support: $2,075/month
Total COGS: $3,320/month
Revenue: $24,225/month (average)
Gross Margin: 86%

Step 2: Project Operating Expenses

Break down into main categories:

Sales & Marketing:

Salaries:
- VP Sales (Month 4): $12,500/month
- Sales Rep 1 (Month 4): $7,500/month
- Sales Rep 2 (Month 7): $7,500/month
- Marketing Manager (Month 6): $8,500/month

Programs:
- Paid advertising: $5,000-$20,000/month (scaling)
- Content marketing: $3,000/month
- Events and sponsorships: $5,000/quarter
- Tools and software: $2,000/month

Research & Development:

Salaries:
- CTO (Founder): $10,000/month
- Senior Engineer 1: $12,000/month
- Senior Engineer 2 (Month 6): $12,000/month
- Designer (Month 8): $9,000/month

Tools & Infrastructure:
- Development tools: $1,500/month
- Testing and QA: $2,000/month
- Product management tools: $500/month

General & Administrative:

Salaries:
- CEO (Founder): $10,000/month
- Operations Manager (Month 9): $7,000/month

Services:
- Legal and accounting: $3,000/month
- Insurance: $1,000/month
- Office and equipment: $2,000/month
- Software subscriptions: $1,000/month

Step 3: Create Hiring Plan

Show when and why you're hiring:

Year 1-2 Hiring Plan:

Current Team (Month 0):
- 2 Founders (CEO + CTO)
- 1 Senior Engineer

Quarter 2:
- VP Sales (support $1M ARR target)
- Sales Rep 1 (to reach 20 customers/month)
- Marketing Manager (to scale inbound leads)

Quarter 3:
- Senior Engineer 2 (expand product capabilities)
- Sales Rep 2 (double sales capacity)

Quarter 4:
- Designer (improve user experience)
- Operations Manager (scale operations)

Year 2 Quarterly Adds:
- Q1: Sales Rep 3, Account Manager
- Q2: Senior Engineer 3, Support Lead
- Q3: Sales Rep 4, Marketing Specialist
- Q4: Product Manager, Engineering Manager

Calculating Key Metrics

Customer Acquisition Cost (CAC)

Formula:

CAC = (Sales + Marketing Expenses) / New Customers Acquired

Example Calculation:

Month 6:
Sales Expenses: $27,500 (2 sales reps + manager)
Marketing Expenses: $12,000 (ads + programs)
Total S&M: $39,500

New Customers: 10
CAC: $3,950/customer

Monthly CAC average should improve with scale:
Months 1-6: $4,000-$5,000
Months 7-12: $2,500-$3,500
Year 2: $1,500-$2,500

Lifetime Value (LTV)

Formula:

LTV = (Average Revenue Per Customer × Gross Margin) / Churn Rate

Example Calculation:

Average Revenue Per Customer: $250/month
Gross Margin: 85%
Monthly Churn: 4%

LTV = ($250 × 0.85) / 0.04
LTV = $5,313

LTV:CAC Ratio

Target Ratios:

< 1: Unsustainable (losing money on each customer)
1-3: Concerning (tight unit economics)
3+: Healthy (sustainable growth)
5+: Strong (efficient growth)

Example:

Year 1 Average:
LTV: $5,313
CAC: $3,200
Ratio: 1.66:1 (acceptable for year 1, needs improvement)

Year 2 Target:
LTV: $6,500 (lower churn, price optimization)
CAC: $1,800 (scaled efficiency)
Ratio: 3.61:1 (healthy, sustainable)

Use MaxVerdic's market research to validate your unit economics assumptions against industry benchmarks.

Payback Period

Formula:

Payback Period = CAC / (Monthly Revenue Per Customer × Gross Margin)

Example:

CAC: $3,000
Monthly Revenue: $250
Gross Margin: 85%

Payback = $3,000 / ($250 × 0.85)
Payback = 14.1 months

Target Payback Periods:

• < 12 months: Excellent
• 12-18 months: Good
• 18-24 months: Acceptable

• 24 months: Concerning

Creating Your 3-Year Projection

Year 1: Foundation and Learning

Goals:

• Achieve initial product-market fit
• Validate go-to-market strategy
• Build core team
• Reach $500K-$1M ARR

Example Metrics:

Revenue: $600K
Gross Margin: 75-80%
Operating Loss: -$800K
Ending Customers: 150-200
Team Size: 8-10 people
Burn Rate: $80K/month average

Year 2: Scaling and Optimization

Goals:

• Scale go-to-market engine
• Improve unit economics
• Expand product capabilities
• Reach $3M-$5M ARR

Example Metrics:

Revenue: $3.5M
Gross Margin: 80-85%
Operating Loss: -$1.2M
Ending Customers: 800-1,000
Team Size: 20-25 people
Burn Rate: $120K/month average

Year 3: Efficient Growth

Goals:

• Demonstrate path to profitability
• Efficient customer acquisition
• Strong team and culture
• Reach $10M+ ARR

Example Metrics:

Revenue: $10M

Ending Customers: 2,500-3,000
Team Size: 40-50 people
Burn Rate: Minimal or profitable

Common Projection Mistakes

1. Hockey Stick Growth Without Explanation

The Mistake: Projecting sudden, unexplained growth acceleration

Example:

Year 1: $500K revenue
Year 2: $2M revenue (4x growth)
Year 3: $12M revenue (6x growth) ← Unrealistic without explanation

Why It Fails: Investors have seen this pattern fail repeatedly

The Fix:

Year 1: $500K (founder-led sales, learning)
Year 2: $2M (first sales team, repeatable process)
Year 3: $6M (scaled team, proven channels)
  - 3 sales reps → 10 sales reps
  - $4K CAC → $2K CAC
  - Channel diversification

2. Ignoring Churn

The Mistake: Projecting all new customers as additive

Why It Fails: Every SaaS business has churn; ignoring it destroys credibility

The Fix: Include realistic churn rates (3-7% monthly for early-stage B2B SaaS)

3. Underestimating Costs

The Mistake: Only accounting for direct hires, not total costs

Example:

Year 2 Plan:
- 15 employees @ $100K average = $1.5M

Missing:
- Payroll taxes (7.65%): $115K
- Benefits (20-30%): $300-450K
- Recruiting costs (15%): $225K
- Equipment and software: $50-100K
Total missed: $690-890K

The Fix: Budget for fully-loaded costs at 1.4-1.5x base salary

4. Unrealistic Sales Ramp

The Mistake: Assuming new sales reps are productive immediately

Reality:

Month 1-2: Onboarding and training (0% productivity)
Month 3-4: First deals closing (25% productivity)
Month 5-6: Building pipeline (50% productivity)
Month 7+: Full productivity (100%)

The Fix: Model realistic ramp times based on sales cycle length

5. Missing Working Capital Needs

The Mistake: Not accounting for payment terms and timing

Example Issue:

• Customers pay Net 30
• You pay employees monthly
• Cash gap creates hidden funding need

The Fix: Include working capital buffer in fundraising ask

Scenario Planning

Create three scenarios to show thoughtful planning:

Conservative Scenario (70% confidence)

Slower growth, higher costs, assumes challenges

Example:

- Longer sales cycles than expected
- Higher churn in early months
- Slower rep ramp times
- Need additional hiring to hit targets

Base Scenario (50% confidence)

Realistic middle ground, used for planning

Example:

- Sales cycle assumptions based on data
- Standard churn rates for industry
- Normal rep ramp and productivity
- Reasonable hiring timeline

Optimistic Scenario (30% confidence)

Faster growth, better efficiency, ideal conditions

Example:

- Shorter sales cycles from brand/network effects
- Lower churn from better product-market fit
- Faster rep productivity from improved processes
- More efficient hiring and onboarding
