I would love to help you figure this out. In order to give you an approximate take home pay for your new salary, I need to know what the pay period is (monthly?) and what do you claim on your W4?
Your current take home pay is not consistent with your current yearly salary (before raise)...
Do you have any other deductions, such as medical insurance, 401k, etc.? If so, how much per pay period?
If I assume Single, 2 on your W4, and post-tax medical deduction, I come up with approx 1905 for your takehome currently, and 2063 for your takehome with your raise.
(difference of approx. 158)
Please note that this is a rough estimate based on info provided and assumptions.---Let me know if you need any additional information!
