What is a dynamic Startup Runway Calculator?
Unlike static runway calculators that assume revenues and expenses remain flat, a dynamic runway calculator applies compounding monthly growth rates. This matches real-world startup scenarios where ad spend and payroll grow, and subscription revenues increase over time.
How is AI Token Cost and ChatGPT API Pricing calculated?
AI pricing is based on the number of tokens (words or word fractions) processed. Standard API providers bill per 1 Million tokens. ChatGPT costs are split into prompt (input) tokens and completion (output) tokens, with output tokens generally costing 3x to 4x more than inputs due to higher compute power demands.
What is Net Revenue Churn and why is negative churn crucial?
Net Revenue Churn calculates lost revenues from cancellations and contractions, offset by expansions (upgrades). Negative Net Revenue Churn occurs when upgrades from existing clients exceed lost revenues from departing clients. It is the primary indicator of high product-market fit in SaaS.
What does the LTV to CAC ratio tell us?
The LTV:CAC ratio measures company acquisition efficiency. An LTV:CAC of less than 3x indicates that you are spending too much to acquire customers relative to what they yield. A ratio between 3x and 5x is the optimal industry benchmark. Higher than 5x indicates you could scale faster by spending more on marketing.
