So let's say I make one hundred thousand dollars in a given year and these numbers will change as the tax code changes but the general idea is the same thing although the details might change so the way the rate schedule works is that the first eight thousand three hundred and fifty (8350) of my 100 000 dollars will be taxed at 10%. so the first 8350 dollars will be taxed at 10%. so I'll be paying what thats pretty easy to calculate I'll be paying eighthundred and thirty-five dollars on that first 8350 dollars. now the next 25 600 or the next from 8350 to 33950 that will be taxed at 15% that will be taxed at 15%. s so this amount right over here i will have to pay 15% on that. so the difference between 33950 and 8350 is 25600. so 25600 times 15%. i will calculate it all at the end using a calculator. now the next 48300 dollars is going to be taxed at 25% so let me draw that over here. so the next, this next slug over here is going to be taxed at 25%. this is the difference between 82250 and 33950 that is 48300. so its going to be 48300 times 25%. and then finally the remainder the amount above 82250 since I dont get into the next bracket above that this part right here is going to be taxed at 28%. so this part right over here is going to be taxed at 28%. let me get my trusty calculator out to figure out what that is so if that's going to be taxed at so the difference between 100000 dollars and 82250. so 100, 100 thousand dollars minus eighty two fifty is 17750 so is 17750 times 28%. and now i can use the calculator to calculate all of these. so its going to be lets do it all at once.
