What is Financial Modeling?
A financial model is a roadmap that outlines your business's financial trajectory, allowing you to:
Forecast revenue, costs, and cash flow.
Assess your profitability timeline.
Prepare for fundraising conversations with investors.
Whether you’re a SaaS startup, an e-commerce brand, or a fintech company, financial modeling examples can help you scale effectively and avoid pitfalls.
The Key Elements of a Financial Model
A comprehensive financial model revolves around three core components:
Revenue Drivers
Cost Drivers
Non-Operating Drivers (e.g., payment collections, interest payments, depreciation)
Let’s unpack each one.
1. Revenue Drivers: Fueling Growth
Revenue drivers are the foundation of your financial model, dictating how your business generates income. Depending on your industry and business model, you can approach revenue modeling in two key ways:
Top-Down Approach: Start with a revenue target (e.g., $1M annually) and determine the actions needed to achieve this goal.
Bottom-Up Approach: Base your projections on granular metrics, such as sales and marketing performance, to calculate how these factors drive revenue growth.
Most financial modeling examples combine both methods for accuracy. Established companies can rely on observable data, while newer businesses or those launching new lines may need to use assumptions or benchmarks.
Examples of Revenue Drivers
1. Average Sales Price (ASP)
The revenue per unit or subscription period (e.g., monthly, annually) is a critical input for your model.
Single Revenue Stream: Simple calculation based on one product or tier.
Multiple Revenue Streams: Requires assumptions for adoption rates and tiered pricing.
💡 Example: A SaaS company charging $50/month per user with a target of 1,000 users would project $50,000/month in revenue.
2. Sales Funnel Metrics
For a bottom-up approach, use funnel data to trace how marketing spend translates into revenue. Key metrics include:
Win Rate: Percentage of qualified opportunities converted into closed deals.
MQL to SQL Conversion: Rate at which marketing leads become sales-qualified opportunities.
Sales Cycle Length: Time from lead generation to customer acquisition.
💡 Example: If your MQL-to-SQL conversion is 10% and your win rate is 25%, you’ll need 400 MQLs to close 10 deals.
Sales Funnel Stages: From Visitors to Customers – TOFU (Top of the Funnel), MOFU (Middle of the Funnel), and BOFU (Bottom of the Funnel) explained with key stages like MQL (Marketing Qualified Lead) and SQL (Sales Qualified Lead).
3. Customer Acquisition Costs (CAC)
Calculate how much you need to spend on marketing and sales to acquire a customer.
Use benchmarks to estimate CAC if direct data isn’t available.
Optimize marketing budgets based on conversion rates and cost-per-lead metrics.
💡 Example: If CAC is $200 and your average customer generates $1,000 in revenue, your unit economics are favorable.
4. Retention rates:
Once a customer is acquired, the frequency in which they continue to purchase from you is a major driver for a business's long-term success. Understanding how long a customer will continue to pay for your service and if they pay more or less overtime will help inform how much it makes sense to invest in acquiring a customer. There are two ways to evaluate retention.
Gross Retention: Looking at a cohort of customers you acquired, what % of these customers are still active X months or years later? Alternatively, from the original revenue base you got from these customers, how much revenue are you still generating? The max gross retention ratio you can have is 100%, since the best you can hope for is to retain this revenue.
Net Retention: Works like gross retention but also factors in any up-sells. Even if you lose some customers, this could be offset by having the remaining customers pay more. Unlike gross retention, net retention has no upper limit and by definition can never be lower than your gross retention.
Gross Dollar Retention vs. Net Dollar Retention: Key formulas explained with examples to evaluate customer retention and expansion, critical metrics for financial modeling and growth analysis.
2. Revenue Drivers: Fueling Growth
Revenue drivers are the foundation of your financial model, dictating how your business generates income. Depending on your industry and business model, you can approach revenue modeling in two key ways:
Top-Down Approach: Start with a revenue target (e.g., $1M annually) and determine the actions needed to achieve this goal.
Bottom-Up Approach: Base your projections on granular metrics, such as sales and marketing performance, to calculate how these factors drive revenue growth.

💡 Example: If CAC is $200 and your average customer generates $1,000 in revenue, your unit economics are favorable.
4. Retention Rates
Retention significantly impacts long-term revenue. Evaluate retention in two ways:
Gross Retention: Percentage of customers or revenue retained over a set period.
Max gross retention is 100%, indicating no customer churn.
Net Retention: Includes upsell revenue, which can exceed 100%.
💡 Example: If 90% of customers stay after a year, but upsells increase total revenue by 20%, net retention is 120%.
Practical Insights for Startups
For venture-backed startups, rapid growth is expected, making these revenue drivers critical for aligning growth strategies and informing product decisions.
Some factors, like pricing, are easier to control. However, if customers resist your price point, adjust it to find the balance between maximum revenue and broad customer adoption.
3. Cost Drivers: Controlling the Burn
Managing costs is essential for maintaining cash flow and achieving profitability. Cost drivers can be divided into two categories, each affecting your business differently:
Fixed Costs
Fixed costs are not directly impacted by revenue and typically include:
Examples of Fixed Costs:
Employee Salaries: Fixed roles like developers, general administrators, and sales staff. These salaries recur regardless of revenue changes, though they may contribute to future growth.
General & Administrative Costs: Includes business insurance, office expenses, audits, and certifications (e.g., SOC2, ISO 27001).
Software Licenses: Subscriptions to SaaS tools like HR platforms (Rippling, UKG), CRMs (Salesforce, HubSpot), or developer tools (ChatGPT, Co-pilot).
💡 Key Insight: Fixed costs often increase in “steps.” For instance, as your customer base grows, you might eventually need additional employees or infrastructure. However, you can control the timing of these increases to match your revenue growth.
Variable Costs
Variable costs scale directly with your revenue, fluctuating as your business grows or contracts.
Examples of Variable Costs:
Cloud Hosting Fees: For SaaS businesses, costs like AWS or GCP increase with each additional customer.
Interchange and Service Fees: Fintech companies incur structural fees from payment processors like Visa, Mastercard, or Stripe.
Customer Support Expenses: Scaling your customer base often means higher support costs, whether outsourced or handled in-house.
💡 Key Insight: While variable costs are tied to growth, they can strain cash flow if poorly managed. Ensure that every new customer adds value to your bottom line.
Cost of Revenue Breakdown: Quarterly visualization of expenses related to human capital, software licenses, and hosting services. A key metric for tracking and forecasting operational costs
Most unit economics judges will include customer acquisition and support expenses within the variable cost components. If your customer acquisition cost (CAC) exceeds a customer's lifetime value (LTV), you risk losing money on every sale. As a founder, finding the optimal balance between growth, margins, and acquisition costs is vital to avoiding unit economics that erodes profitability.
With your revenue and cost drivers mapped, you’ll better understand your profitability timeline and funding needs. However, remember to also consider non-operating costs.
Customer Acquisition Cost (CAC) Formula: Calculate CAC by dividing total sales and marketing expenses by the number of new customers acquired, a key metric for evaluating startup growth and efficiency.
Optimized Section: Non-Operating Drivers: The Cash Flow Catalysts
Non-operating factors play a critical role in managing cash flow and determining the capital your business needs to survive and grow. These often-overlooked drivers can either strengthen your financial health or drain your cash reserves.
1. Working Capital
Efficient working capital management is essential for maintaining healthy cash flow. Key components include:
Payment Terms: Understand how customers pay—upfront, annually, or on a per-use basis. Shorter payment terms improve cash flow.
Collection Timelines: Monitor how long it takes to receive payments (e.g., Net 30, 60, or 90 days). Longer timelines can delay liquidity and strain operations.
💡 Example: If suppliers require payments within 30 days, but customers take 90 days to pay, the gap can create a cash crunch. Faster collections can bridge this gap, reducing the need for additional financing.
2. Depreciation
Although depreciation is a non-cash expense, it directly impacts cash flow planning for asset-heavy businesses.
Why It Matters: Assets like machinery and vehicles eventually need replacement. Ignoring depreciation schedules can lead to unexpected cash shortages.
Actionable Insight: Create a depreciation forecast to plan for replacement costs before they impact your cash reserves.
3. Interest Rates
Interest rates, though subtle, can significantly influence cash flow as your business scales.
Positive Impact: Idle cash in bank accounts can earn interest, contributing to revenue.
Negative Impact: Loans and credit lines increase cash burn through interest payments, particularly in high-rate environments.
💡 Pro Tip: Optimize your financing strategy by comparing the cost of debt to the interest earned on surplus cash. This can help balance your cash flow over time.
