What is your product LTV and CPA?

Hey guys. I know it's a very personal question for any product owner so don't stress if you're not ready to answer. Will start with mine numbers:

1. uvimate.com - LTV: ~9.5$, CPA: 0.0001$ (some initial investment in Icon+ASO+SEO)
2. openuv.com - LTV: ~300$, CPA: 100$ (currently just SEO, will need to do high touch sales going further and it will never scale).
3. fullstack.cafe - LTV: ~17$, CPA: 25$ (just launched, currently investing in SEO, blogging plus personal touch on LinkedIn and Dev.to)
