How to work out salary increase percentage 
Subtract your old salary from your new salary. 
Say you made $45 , 000 per year at your old job and that you accepted a new position making $50 , 000 per year. This means you would take $50 , 000 and subtract $45 , 000.
OPTIONS:
- $ 50 , 000-$45 , 000 = $5 , 000. If you receive hourly pay and don't know your total yearly earnings, you can simply use the old and new hourly rate in place of the salary.
- To get your current current salary, you must multiply $50 , 000 by. 50 which equals $5 , 000 you worked out together.
- You would subtract $50 , 000 from the $45 , 000 to get your new salary. For example, if your current salary is $150 , 000 you would subtract $150 to get your new salary.
- The remaining $70 , 000 would equal $100 , 000 in your new salary. If you have less in your previous salary than you did in your current position, you should subtract $100 , 000 from your current salary and make the difference.
$ 50 , 000-$45 , 000 = $5 , 000. If you receive hourly pay and don't know your total yearly earnings, you can simply use the old and new hourly rate in place of the salary.
