What is Financial Modeling and why do we need it?
SaaS financial modeling is the process of creating a detailed representation of the financial aspects of your business, enabling you to forecast revenue, expenses, and profitability over a specific period. It allows you to gain a deeper understanding of your business’s financial health, identify potential risks and opportunities, and make informed decisions about pricing, growth strategies, and resource allocation. By developing accurate financial models, you can analyze various scenarios, assess the impact of different variables, and determine the viability of your products or services.
How does this apply to a SaaS business model?
There are many similarities in financial modeling for SaaS businesses versus other businesses. Although most of a SaaS startup’s activities can be centered around the product being built, the importance of financial modeling cannot be overlooked.
First and foremost, financial models help you assess the feasibility of your product or service and validate your go to market strategy. By considering your costs, including development, marketing, and support expenses, you can determine your gross margins and track your net profit. This information is essential for determining if your idea and approach makes sense financially. If your SaaS business is already established, financial models will help with evaluating your business’s financial performance, identifying areas for improvement, and optimizing your pricing and cost structures.
In the following sections we’ll cover the most important areas of SaaS financial modeling, and we’ll learn how these contribute to your business’s growth. But before we dig deeper into this, let’s cover a few terms that you’ll run into throughout the article:
Understanding SaaS Metrics
Which “financial aspects” should be included in your financial model?
Tracking and analyzing the right metrics is vital for measuring the success and growth of any business. But what is in fact a metric?
You can consider a metric as any quantifiable measure that provides objective data about a particular process, activity, or outcome. A metric is used to track and evaluate performance and provide insights into various aspects of a business or even a project. Metrics can be financial but also non-financial and can be used to monitor efficiency, productivity, quality, customer satisfaction, and other performance dimensions. For example, the number of units produced per hour, customer satisfaction ratings, or website traffic are all metrics. As we are talking about these in the context of financial models, we’ll focus more on the financial ones in the course of this article.
Now that you have an understanding of what a metric is, how do you know which ones should be tracked?
Choosing the key metrics, also known as key performance indicators (KPIs), is a process that needs to be tailored to the SaaS business model. KPIs are a subset of metrics that are specifically chosen to reflect the most critical areas of performance for an organization. They are aligned with strategic objectives and help gauge progress towards your goals. A few examples of the most commonly tracked KPIs for SaaS businesses are Monthly Recurring Revenue (MRR), Customer Acquisition Cost (CAC), Churn Rate, and Average Revenue Per User (ARPU) or Customer Lifetime Value (CLTV), sometimes referred to as simply Lifetime Value (LTV).

Once you have revenue and expense projections, calculate your gross margins and net profit.
- Consider Cash Flow
SaaS businesses often face unique cash flow dynamics due to subscription-based revenue models. Project your cash inflows and outflows, including operating expenses, capital expenditures, and any financing or investment activities. This will help you understand your cash position and potential funding needs.
- Incorporate Metrics
Integrate key SaaS metrics into your financial model, such as Monthly Recurring Revenue (MRR), Customer Acquisition Cost (CAC), Churn Rate, and Customer Lifetime Value (CLTV). This will provide a holistic view of your business’s financial health and allow you to monitor performance against your goals.
- Conduct Scenario Analysis
Perform sensitivity analysis by adjusting critical assumptions to assess how changes in variables impact your profitability. This helps you understand the potential risks and opportunities associated with different scenarios, evaluate the robustness of your business model, and guides your decision-making process.
- Validate and Iterate
Regularly review and validate your financial model against actual performance. Update your assumptions, incorporate new data, and refine your projections as your business evolves. Continuously iterate and improve your model to ensure its accuracy and relevance.
The above provides a quite detailed approach to creating a financial model. If building your first financial model seems like a daunting task, don’t be afraid to seek expert advice! Consult with finance professionals or industry experts to ensure the accuracy and relevance of your financial model. They can provide valuable insights and guidance throughout the process.
Although it’s already included as the last step in the list above, we cannot emphasize the importance of this enough: a financial model is a dynamic tool that should evolve alongside your business. Continuously refine and improve your model based on real-time data and feedback to make it a reliable resource for decision-making.
We will now discuss the specific steps involved in creating a financial model for SaaS and address the burning question of how to build a SaaS financial model
Forecasting Revenue for SaaS Companies
Forecasting revenue for SaaS companies involves estimating future revenue streams based on various factors and assumptions. While it’s impossible to predict revenue with absolute certainty, there are several methods and best practices you can follow to create a reliable revenue forecast model. Here’s a guide to help you in the process:
Methods for Forecasting Revenue for SaaS Companies
- Top-Down Approach
This approach starts with estimating the total addressable market (TAM) for your SaaS product. By considering the size of the market, market share potential, and competitive landscape, you can determine a realistic revenue projection. This method provides a broad overview but may require additional research and analysis.
- Bottom-Up Approach
This approach involves breaking down your revenue forecast by individual customer segments, pricing tiers, or subscription plans. By estimating the number of customers or subscribers in each segment and applying average revenue per user (ARPU), you can build a more granular revenue projection. This method requires a deep understanding of your target market and customer behavior so it might be difficult to adopt it if you are just starting up your business.
- Cohort Analysis
Cohort analysis focuses on understanding the behavior and revenue generation of specific customer cohorts over time. A cohort can be any group of users with shared characteristics. The defining characteristics of a cohort can vary from the industry in which the users are active, to job titles, demographics or even the usage patterns of the product. By analyzing the revenue patterns of different cohorts, you can project future revenue based on customer acquisition, retention, and expansion rates. This method provides insights into customer lifetime value (CLTV) and churn rates, enabling more accurate revenue forecasts. Similar to the Bottom-Up approach, this works better when you already have an active user base.
To create a revenue forecast model for a SaaS company, consider the following steps
- Define Assumptions
Start by identifying the key assumptions that drive your revenue projections, such as customer acquisition rate, churn rate, expansion rate, and pricing structure. These assumptions will form the basis of your model.
- Gather Historical Data
If available, analyze historical revenue data, including trends, growth rates, and seasonality. This data serves as a reference point and helps you identify patterns and factors influencing revenue fluctuations.
- Choose a Time Horizon
Determine the time period for your revenue forecast, whether it’s monthly, quarterly, or annually. Align the time horizon with your business goals, funding cycles, or reporting requirements.
- Build Revenue Drivers
Identify the revenue drivers specific to your SaaS business, such as the number of new customers acquired, customer retention rate, expansion revenue from upsells or cross-sells, and any one-time revenue sources. Develop formulas to project these drivers over time based on conversion rates.
- Consider External Factors
Closely related to #4 above, you need to take into account external factors that can impact revenue, such as changes in the competitive landscape, regulatory changes, or macroeconomic conditions. Stay informed about industry trends and market dynamics that can affect your forecast.
- Apply Pricing Strategies
Consider your pricing tiers, discount policies, and potential changes in pricing over the forecast period. Incorporate any pricing adjustments and their impact on revenue into your model.
- Involve Cross-Functional Collaboration
Collaborate with sales, marketing, and customer success teams to gather insights and validate your revenue forecast. Their input and expertise can provide a more holistic view of customer behavior, market trends, and revenue-generating opportunities.
- Validate with Data and Adjust
Regularly review and validate your revenue forecast against actual performance data. Adjust your assumptions and projections based on real-time insights and market feedback. Continuously iterate and improve your forecast model as your business evolves.
Revenue forecasting is a critical part of financial modeling. As such, it is likewise an iterative process that requires continuous refinement and adjustment.
Creating a SaaS Budget
So far we’ve managed to cover key aspects of the SaaS financial model related to revenue. Now it’s time to focus on estimating the costs or expenses and budgeting accordingly to understand what is required for meeting the revenue goals.
This process involves forecasting and planning for various expenses to ensure the financial health and sustainability of the business. Effective budgeting is essential for making informed decisions, setting financial targets, and monitoring performance.
Why is budgeting important?
- Financial Planning: Budgeting provides a roadmap for financial planning by outlining the expected revenue and expenses for a specific period. It helps in setting financial targets, allocating resources, and making informed decisions about investments, hiring, and growth strategies.
- Resource Allocation: Budgeting helps allocate resources effectively by identifying areas of high priority and optimizing expenditure. It allows you to allocate funds to critical functions such as product development, marketing, customer support, and infrastructure based on their strategic importance.
- Performance Evaluation: Budgets serve as a benchmark for evaluating the actual financial performance of the business. By comparing actual results with the budgeted figures, you can identify variances, analyze the reasons behind them, and take corrective actions if needed.
- Cash Flow Management: Budgeting helps manage cash flow by forecasting inflows and outflows of cash. It enables you to plan for expected cash needs, identify potential cash shortfalls or surpluses, and take necessary measures to maintain adequate liquidity.
What expenses should be considered in your SaaS budget?
Here are the main categories of expenses that should be considered in order to achieve a successful budgeting of your business operations:
- Product Development: Allocate resources and budget for product development activities, including research and development costs, design, engineering, and quality assurance. Consider new feature development, bug fixes, technical debt reduction, and other product-related investments.
- Marketing and Sales: Allocate funds for marketing campaigns, advertising, content creation, lead generation, events, and sales activities.
- Customer Success and Support: Budget for activities aimed at ensuring customer satisfaction and support, such as customer success programs, training and onboarding, customer support tools, and personnel costs associated with support teams.
Whereas the above 3 categories are most often taken into account, there are others which should not be overlooked:
- Infrastructure and IT: Allocate funds for cloud infrastructure, hosting services, data storage, server maintenance, security measures, and other IT-related expenses necessary to support your SaaS platform.
- General and Administrative Expenses: Include general overhead costs such as office rent, utilities, insurance, legal fees, accounting services, and other administrative expenses required to run the business.
Once you manage to estimate all the above costs you should have a pretty clear understanding of your inflows and outflows so putting together the budget consists of simply bringing this information together.
