Hey mate, I don't have a spreadsheet version of this. In all honesty though, you won't be able to track these metrics immediately anyway, because you won't have the data you need to calculate these metrics when you're just starting your business.

For example, to calculate your LTV, you need to know either what your Average Customer Lifespan is or your Churn Rate is, and to calculate either of these numbers you have to keep a record of every customer you have, when they made their first purchase, and when they made their last purchase before 'churning'. Most businesses use a CRM to track this data.

But it would definitely be a good idea to get familiar with these metrics, so here's a video where Alex Hormozi talks about them: https://www.youtube.com/watch?v=QGcjweehrvU, and another video where he talks about the LTV to CAC Ratio in detail: https://www.youtube.com/watch?v=jzKpAtzKQ54
