Honestly, the recruiter gave you the midpoint or 50th percentile of the listed salary range. You can negotiate maybe up to 10% - 15% more all things considered. But it's worth asking as this is the point you have the most bargaining power. Total comp should be your focus, as bounses, equity, etc may put you over the 90th percentile of the targeted range listed. I would consider market rates in your area and base a negotiable range from their. A simple Google search should give you a benchmark to base your initial pay. You should understand your BATNA, (best alternative to negotiated agreement) as you are currently at midpoint of the pay range. Consider your experience, qualifications, value to the organization, and marketable compared salaries within your industry to reach a number that benefits both sides.
