R2 pricing

I want to get started with cloudflare R2, I need to know that what is the minimum amount should I need to pay if I use more than 10gb, consider I used 5gb do I need to pay for the particular 5gb or a minimum of dollars, why because previously I’m using wasabi they charge minimum of 5$ whether you use 1TB or not you must pay 5$, that’s why I’m asking is there any minimum amount to pay for each month

In my case for example
$0.015 *50 = 0.075$
Only this much amount should I need to pay or a minimum of some dollars

R2 pricing is based on storage & operations performed,
