Quick answer
An $18 base rate with 2 kids (+$2) for 4 hours comes to $20/hour, or $80 for the evening.
How it works
Start with the going hourly rate in your area, then add a dollar or two per additional child. Multiply by the hours to get the total — rounding up is a nice gesture for a sitter you want to keep.
Formula
Rate = Base + (Extra children × Add-on); Total = Rate × Hours
Assumptions & limitations
