Keyword Planner Issue
In the keyword planner, I entered all of my keywords, set the bid for $2 and daily budget at $10. It says that I should be getting 179-242 clicks weekly, have 4.01K-5.42K impressions, and spend $20.6-$27.8 weekly. But if you calculate those estimated clicks based on the keywords bid which is $2, it is very far to the estimated spend of $20.6-$27.8 weekly. Please review it. Thanks!

Thanks for your feedback. The weekly estimated spend is impacted by the keywords, bid, budget, and account historical performance, etc.
In this case, the estimated spend was capped by budget thus you can see a shaded area in the graph.
You can try to increase your budget or decrease your bid to adjust.
