Thanks for reaching out, I hope you are well.
Congrats on your first post in the community, Whoop!
New Relic bills on just two factors: ingested data and billable users. In this doc, we’ll explain how our 2 different pricing model works, what you get for free, and other details.
Also I would suggest revising our New Relic pricing and billing doc for more details on ingested data billing and billable users. Its also worth noting New Relic accounts are 100% free to create and come with a 100GB free data per month.
Additionally I note that the accounts in question are both free accounts, once they both adhere to the free limits on free tier accounts they wont be charged. Should you choose to add extra full platform users or user more than the 100GB free data then charges would apply.
I hope this was helpful, should you have any questions or updates please do reach out.
