How to negotiate promotion and salary after expanding responsibilities?

[AaronHC]

I'm a senior project manager preparing to negotiate a significant promotion and salary increase with my company's leadership next month. My role has expanded far beyond its original scope over the past two years, and I've taken on direct reports and budget responsibility. For others who have successfully navigated this type of internal negotiation, what strategies did you use to quantify your value and build your case? How did you research an appropriate salary range beyond standard websites, and what was your approach for the actual conversation—did you lead with a number or let them make the first offer? I'm also unsure how to handle potential pushback about budget constraints.

Two quick things that helped me when negotiating a promotion: (1) build a concise business case that shows the expanded scope (teams, budgets, projects) and 3–4 measurable impacts (revenue lift, cost savings, efficiency or risk reduction). (2) anchor with a market-informed salary range, plus a concrete plan for growth. I used a one-page sheet plus a short slide deck and practiced delivering it aloud a few times.
