<prompt> Human: Hi all, I started a full time job in January of 2017. I get paid bi-weekly, so every other Thursday in my case. Ive just found that the third paycheck I receive next month will be money that isnt accounted for within my budget. So this will be extra money I have received. Is this true? Or am I looking at this the wrong way?  <response>: So this will be extra money I have received. Is this true?Well, if your salary is Xyear, you should be getting X26 per paycheck. So in most months you get X26 2 but occasionally you get X26 3. Its not really extra money, but its an atypical amount. Its still adding up to X across the whole year.If your budget was based on receiving X26 2 every month, then you can think of this as extra because your system of accounting has been thinking you earn X26 2 12 months in a year. Thats 2426 X. If your system of budgeting was based on thinking that was your annual income, then it is extra money equivalent to 226 X across the year. But youre still not ending up with more than X across the year.
