<prompt> Human: My boyfriend and I have been living together for 3 years and the question of how we split our finances to pay bills is source of issues. Because his basic salary is higher than mine, we decided to split proportionally according to our respective salary. The source of disagreement is about the extra income he earns due to the nature of his job which he doesnt want to add in the balance The extra income can be an additional 5 months salary bonusallowances. Due to the nature of my job, I do not have any bonusesallowances. All I earn is considered as my income. So for those of you who split proportionally, do you include extra allowances and bonuses as your total income? Or do you only consider your basic salary?  <response>: The people I know who splits according to income count everything paid out as income. When they deal with non predictable income like a bonus they adjust accordingly year to year.The main point isnt really what others do though. It is what you want to do and what you find fair. If you think it is unfair the way you do it now you have to address that. Either by accepting things as they are or by changing things. The hard part is reaching a compromise you and your SO can live with.
