As Du poisson said, you do get R$21,900 after a year, but the annual OBC costs $129.95, which is actually a deal cause if you spent that much money on robux, you would only get around R$10,800 (or with BC/TBC/OBC = R$15,900)

so i would agree with you to save for OBC

but to answer your question you do get R$21,900 a year!
