6 Startup Financial Model Templates (Google Sheets)

Financial models force clarity. How will you make money? What does it cost to acquire customers? When do you break even? Investors will ask, and you should know.

But building from scratch is tedious and error-prone. Templates give you the structure. You fill in your assumptions.

1. SaaS Financial Model For subscription businesses. Models MRR, churn, LTV, CAC, and growth scenarios.

Key inputs: Pricing, churn rate, customer acquisition cost, growth rate. Where to find: Christoph Janz's SaaS Financial Model (free), Baremetrics templates.

2. Marketplace Financial Model For two-sided marketplaces. Models supply, demand, take rate, and liquidity.

Key inputs: Take rate, transaction volume, supply/demand growth. Where to find: Point Nine Capital templates, Version One marketplace model.

3. E-commerce Financial Model For product-based businesses. Models COGS, inventory, marketing spend, and margins.

Key inputs: Product costs, average order value, return rates, ad spend. Where to find: Shopify's free financial templates, general e-commerce models on Slidebean.

4. Service Business Financial Model For agencies, consultancies, and freelancers. Models billable hours, rates, and utilization.

Key inputs: Hourly/project rates, utilization rate, team size. Where to find: SCORE templates, HubSpot service business templates.

5. Mobile App Financial Model For apps with downloads, conversions, and in-app purchases or ads.

Key inputs: Download projections, conversion rate, ARPU (average revenue per user). Where to find: Traction templates, app-specific models on Gumroad.

6. Hardware/Physical Product Financial Model For products with manufacturing, inventory, and supply chain.

Key inputs: BOM (bill of materials), manufacturing costs, shipping, inventory turns. Where to find: SCORE manufacturing templates, hardware-specific models.

Step 1: Understand the structure. Most models have: assumptions tab, revenue projections, cost projections, P&L summary, cash flow.

Step 2: Replace assumptions with yours. Don't change formulas first. Change inputs: your pricing, your costs, your growth assumptions.

Step 3: Test with scenarios. Create optimistic, realistic, and pessimistic cases. What happens if growth is 50% lower? What if churn doubles?

Step 4: Remove what doesn't apply. Templates include things you might not have. If you don't have employees yet, simplify that section.

Step 5: Add what's missing. Your business might have costs or revenue streams the template doesn't include. Add rows for your specifics.

Step 6: Document assumptions. Note why you chose each number. "CAC of $50 based on current Facebook ad performance" is better than unexplained numbers.

Revenue drivers:

• Customer growth rate (new customers per month)
• Pricing (and any changes over time)
• Churn/retention (what % of customers stay)

Cost drivers:

• Customer acquisition cost (CAC)
• Cost of goods sold (COGS) or delivery
• Fixed costs (rent, salaries, software)

Often overlooked:

• Payment processing fees (2-3% adds up)
• Hiring timeline (when you'll need people)
• Tax obligations
• Seasonal variation

Investors scrutinize assumptions more than outputs. Defensible assumptions beat impressive projections.

Clear assumptions. Every number should trace back to a documented assumption.

Scenarios. Show what happens under different conditions.

Conservative and aggressive cases. Investors want to see your realistic view, not just the dream.

Monthly detail for year 1, quarterly for years 2-3. Show you've thought through early stages.

Clean formatting. Inputs in one place, formulas in another. Color-coded for clarity.

Alignment with deck. Numbers in your model should match what you present in your pitch.

How far out should projections go? 3 years is standard. Year 1 in detail (monthly), years 2-3 more high-level (quarterly or annual).

Are Google Sheets good enough for investors? Yes. Most early-stage investors don't care if it's Sheets or Excel. Clarity matters more than tool choice.

What if my projections are completely wrong? They will be. Everyone's projections are wrong. The point is demonstrating you've thought through the business, not predicting the future perfectly.

Should I pay for a premium template? Free templates cover most needs. Premium templates ($50-200) might have better structure or support, but aren't necessary.

When do I need a real financial model vs a template? Templates work until you raise significant funding or have complex business logic. Series A and beyond often need custom models.
