In the Commission Plans tab, you can see which commission plan is your Selected Plan and you can see your commission plan History.

For each commission plan you will be able to see the name, description, type, when it went into effective, when it is going to end, what the report is based on if it is a tiered plan, if it resets on anniversary date of the plan, and when transaction income counts towards this plan. It will also show the current contribution to the plan if it is currently the active plan and it is tiered.
