Frequently Asked Questions

How are AI API costs calculated?

AI APIs charge per token — small units of text (roughly 4 characters each). You pay separately for input tokens (your prompt) and output tokens (the response). Multiply the per-token price by your usage volume to get your total cost.

Which AI model is the most cost-effective?

For most use cases, smaller models like GPT-4o mini, Claude 3.5 Haiku, or Gemini 1.5 Flash offer 10-100x lower cost than flagship models with only a modest quality drop. Use large models only when task complexity demands it.

What is a good LTV:CAC ratio?

A 3:1 ratio is considered healthy — your customer is worth 3x what you spent to acquire them. Below 1:1 means you are losing money. Above 5:1 may mean you are underinvesting in growth.

How is CAC calculated?

CAC = (Total Marketing Spend + Total Sales Spend) / Number of New Customers Acquired. Include all costs: ads, salaries, tools, content creation, commissions, and overhead.
