At my company, per-year health-insurance premiums increase by $1044 once a salary is greater than or equal to A. A does not seem to change with time, and it is the highest value where a premium increase occurs. The premiums are piece-wise constant with respect to salary.
I currently make B, such that, if I received a 2.28% raise, I would make A. I expect my new salary to be between A and (A+$1300), with the latter being a 3.3% increase.
The only other factors that come to mind that would be affected by salary are 1) 10% company match for 401(k), and 2) raises are expressed in terms of percentages of existing salary; these percentages are functions of performance category and ratio of current salary to midpoint. Therefore, there is compounding, but the percentage can be reduced if the current salary is higher.
Based on some crude calculations that consider the premium increase and the 401(k) matching, it seems it would be better to make (A-$0.01) than it would be to make between A and (A+$950).
Therefore, if my new salary is between A and (A+$950), should I request (A-$0.01)? Are there other factors I should consider?
Update I ended up creating a spreadsheet of possible scenarios and noted the significantly more limited range for which it would take more than a couple of years make up the difference. I would have expressed concern if I ended up in that range.
Fortunately, however, my increase for this year exceeded my expectations, to the point that the premium increase was not an issue.
