How much is helix a month?

Excuse me, I'm a bit confused about the pricing structure for Helix. Could you please clarify for me how much it costs to use Helix on a monthly basis? I understand that prices can vary depending on factors such as usage and subscription levels, but I'm just looking for a general idea of what I might be expected to pay if I were to subscribe to Helix for one month. Thank you for your help.
