I am using Project 2010 Standard. when I add a new task to a project then assign resources to that task, and the day(s) or percent of day, Project calculates one additional hour of cost per resource for each project. For example, if I have a developer and I need 8 hours and my cost for that developer is $50 per hour, I enter 1 day in the duration and the system shows 8 hours, but the cost calculates at $450 not $400. if I have the same task, for 1 day duration and 16 hours, with two developers, the cost will calculate at $900 and not $800.
I have changed the calendar to show that the day is 9 - 5 and the working hours per day is 8 hours. (I saw the same issue with 8 - 5 with 8 hours in a working day and suspected that it was calculating 9 hours internally per day but this isn't the issue.)
If I indicate that the task will take 2 days with 2 developers, it will calculate 32 hours, 2 days duration, but the costs will be $1700 which is equal to 8 hours * 2 people * 2 days, plus 1 additional hour per resource.

I tried to reproduce your issue using the following steps.
1. Create a new project
2. Create 2 new resources with an hourly rate of $50
3. Create a new auto scheduled task of 1 day, and assign resource 1. The cost is displayed as $400, which is correct.
4. I checked the Project calendar. The standard times are 8:00 - 12:00 and 13:00 - 17:00 (8 hours per day).
So basically, I was not able to reproduce your situation. Then I switched to the Task Usage View and added the hours in the date format in the general Project Options, to check if the starting time and ending time were on the same day. For me they were, but maybe for you not.
I also checked Work and Duration:
5. Add the cost column in the Task Usage. I saw that the Duration was 1 day, but the work for resource 1 was 9 hours (so $450). So maybe that is the same in your case.

Yes, this is exactly the issue. Point number 5 is that the work for resource 1 was 9 hours, it should be 8 hours. Project is adding an additional hour to the duration for the first day of any task. If the task is more than a day, then each subsequent day only has 8 hours.
How can I ensure that I only get 8 hours on the first day and not 9 for the resource? If there are two resources assigned to the task, they each get 9 hours for the first day and if the task exceeds one day, then they both only have 8 hours for each day there after. If there is less than 1 day, there is an additional hour per resource regardless of the number of hours assigned.

Tuesday, March 27, 2012 3:32 PMYes, both the cost use and standard rate are set at $50 per hour.
Tuesday, March 27, 2012 3:35 PMI also have one task, the Kickoff task that is for only 2 hours with 4 people all at $50 per hour. The cost for this task is $600 when it should be $400. Again because Project seems to be adding 1 additional hour per person per task.

It is not adding an hour per task. It is adding $50 per task. Cost per use should only be used in very specific cases where using a resource costs something in addition to the hourly rate. An example would be a delivery fee for some equipment or a setup fee.
I would set cost per use to 0 and you should start seeing what you expect.
