A fixed budget is often a fixed row in a salary band. It is not automatically a fixed total package. This page is built around that distinction. The script agrees that the band may be real, then asks whether a signing bonus or the equity grant sits outside it, and what a review in six months would require.
Separate the buckets
Ask which budget is fixed: base for this level, the whole cash package, or every form of pay including equity. People use “budget” for all three. The answer changes your move. If only base is fixed, talk about a signing bonus. If cash is fixed and equity is not, talk about the grant. If they say every bucket is closed, stop looking for a hidden one.
A six-month review is not a raise. It is a meeting unless the letter says what happens to pay if you meet a standard. If you are willing to join on that promise, ask for the standard and the timing in writing. If you are not, do not pretend the review closed the gap.
Stay collaborative. The person on the phone often cannot edit the band themselves. A clear question they can take upstairs is more useful than a speech about what you are worth. The sample numbers are only there so the anchor is concrete. Your gap may be smaller or larger.
Questions
Should I keep negotiating after they say the budget is fixed?
Ask which part is fixed. If the answer is “all of it,” decide. Repeating the target without a new fact does not change a band.
