How It Works
A transparent look at the logic behind the analysis.
Define Customer Acquisition Cost
Enter your average Customer Acquisition Cost (CAC). This is the total cost of your marketing and sales efforts divided by the number of new customers acquired during a specific period of time.
Input Customer Lifetime Value
Provide your average Customer Lifetime Value (LTV). This represents the total net profit you expect to generate from a single customer over the entire duration of their relationship with your business.
Account for Burn & Capital
Enter your Monthly Burn Rate (total operating expenses minus revenue) and your current total Cash In Hand. These figures are essential for determining your company's survival timeframe and fiscal health.
Review Viability Analysis
The calculator processes your inputs to deliver a detailed report including your efficiency ratio, months of survival remaining, and a summary status indicating the current health of your business model.
Why This Matters
Assess your business model's long-term sustainability by analyzing CAC, LTV, monthly burn rate, and total cash runway metrics.
Validate Business Fundamentals
By tracking your LTV to CAC ratio, you can determine if your core business engine is efficient. A strong ratio ensures that you are creating more value than you are spending to acquire it, which is vital for long-term survival.
Prevent Liquidity Crises
Use accurate runway data to identify potential cash flow shortages months before they happen. This foresight allows you to secure necessary financing or adjust your spending to ensure your business remains operational.
Inform Strategic Pivots
Enhance your decision-making with data-backed viability scores. If your metrics indicate your model is 'At Risk,' you can take proactive steps to improve your unit economics or extend your runway before it's too late.
Secure Investor Confidence
Provide potential investors or lenders with professional and transparent viability metrics. Demonstrating a clear understanding of your business's sustainability builds trust and increases your chances of securing funding.

Sample Output
Input Example
Interpretation
With an LTV five times higher than your CAC, your core unit economics are excellent. However, with only five months of cash runway remaining, your business is in a 'Moderate' status. While the engine is efficient, you need to either reach profitability or secure more capital within the next few months to ensure long-term survival.
Result Output
LTV : CAC Ratio: 5.00x; Runway: 5.0 Mo; Status: Moderate.
Common Use Cases
Fundraising Preparation
Determine your exact runway and efficiency metrics before meeting with venture capitalists. Providing data-backed viability scores builds founder credibility and helps in negotiating better valuation terms.
Strategic Health Audit
Regularly monitor the sustainability of your business to ensure you aren't heading toward a cash crunch. This is crucial for maintaining independence and making confident long-term investment decisions.
Scale Viability Analysis
Assess if your current acquisition channels can support aggressive scaling without breaking the business model. Crucial for identifying the point where diminishing returns may impact overall viability for the brand.
Budget Risk Assessment
Project the total viability impact of proposed departmental budgets to ensure the company remains on a sustainable path. Helps in high-level resource planning and risk mitigation.
Troubleshooting Guide
Inaccurate LTV Projections
Ensure your LTV calculation is based on net profit, not just gross revenue. Overestimating customer value will artificially inflate your viability score and lead to dangerous over-investment in acquisition.
Ignoring Churn Impact
High churn can quickly destroy a high LTV. Be sure your customer lifetime estimates accurately reflect your current retention rates to ensure your viability analysis remains realistic and actionable.
Monthly Burn Volatility
One-time expenses can skew your burn rate. Use a 3-month trailing average for your monthly burn to get the most accurate measure of your business's consistent cash requirements for your company.
Pro Tips
- Aim for an LTV to CAC ratio of at least 3x. This is widely considered the minimum benchmark for a healthy and scalable subscription or recurring-revenue business model for your brand.
- Monitor your 'CAC Payback Period' alongside your viability. Even with a high LTV, a long payback period can create significant cash flow challenges that threaten your business's survival.
- Use this calculator to determine your 'Breakeven Burn'. Identify the exact amount of revenue growth needed to stop burning cash and reach self-sustainability for your current operations.
- Factor in 'Internal OpEx' when calculating your CAC. Remember to include the salaries of your sales and marketing teams, not just your direct ad spend, for a true measure of acquisition cost.
- Regularly audit your high-value customer segments. Focus your resources on the cohorts that have the highest LTV to CAC ratios to improve your overall business viability and growth potential.
- Incorporate 'Net Negative Churn' into your long-term planning. If expansion revenue from existing customers exceeds lost revenue from churn, your business viability increases exponentially over time.
- Communicate viability metrics to your management team. Aligning everyone around clear efficiency and runway targets builds a shared sense of urgency and helps in driving the collective effort needed.
Frequently Asked Questions
What is the 3x LTV to CAC rule?
The 3x rule is a common benchmark in the SaaS and startup world, suggesting that a customer's lifetime value should be at least three times the cost to acquire them. This ratio ensures you have enough margin to cover operating expenses, support, and future growth while remaining profitable.
How can I improve my business viability effectively?
The most common and effective ways to improve viability include lowering your CAC through better targeting, increasing your LTV through upselling or price increases, and reducing your monthly burn rate by optimizing operating expenses.
Does a high runway always mean a business is viable?
No. A business can have a long runway because it recently raised capital, but if its LTV to CAC ratio is less than 1x, it is effectively 'buying' customers for more than they are worth. Without fixing the underlying economics, the business is not viable long-term.
Should I include my own salary in the burn rate?
Yes, for a true measure of viability, you should include all costs required to run the business, including fair market salaries for the founders. Excluding these costs provides a false sense of sustainability and runway for your company.
What is the difference between viability and profitability?
Profitability means you are making money now. Viability means your business model has the potential to survive and thrive over the long term. A startup can be viable (high LTV/CAC) even if it isn't currently profitable due to high growth investments.
How often should I re-calculate my business viability metrics?
You should review your viability metrics monthly and perform a deep-dive analysis quarterly. Because market conditions and acquisition costs shift quickly, staying on top of these KPIs is essential for ensuring your business remains on a sustainable growth path.
