The Quickest Way to Estimate How Much Your Startup Needs to Raise
Tell me three numbers and I can estimate the amount of capital your startup will need to raise. Which figures are those? The startups’ revenue target, the average revenue per customer and the average cost of customer acquisition.
For example, I’d like to estimate the cost for my SaaS startup to reach $100M in annual recurring revenue (ARR). My typical customer pays $25k average contract value (ACV) and my cost of customer acquisition (CAC) is $29k. I estimate a 14 month payback, which is the average according to the 2016 PacCrest survey. To calculate CAC, we take the 14 months of payback divide by 12 months and multiply by the ACV. To reach $100M requires 4,000 customers. Each of the 4,000 customers cost on average $29k. This math implies spending $116M to acquire those customers.
