<prompt> Human: I started a new job recently with a 70k salary, and the first paycheck for my first week I started in the middle of a pay period was 1080 net. However, when I got my second paycheck that was for my first full two week pay period, it was 1905 net.The weekly gross amount of 1346 was still the same, but why wasnt my two week paycheck 2160 1080x2? Isnt my tax rate based on my annual salary rather than what my paycheck is?Im wondering because Im trying to figure out what my new total monthly income will be, but maybe Im just missing something here. Should I just assume my monthly net income will be 3810 1905x2?  <response>: The first check assumed youd make 26 checks of that much. The second check uses what will be your rate for a full year and is what you should expect
