First, you have to check his contract -- he may not be able to receive compensation for vacation time not taken . . . which is a standard in the first year of many contracts....
If he does, and if the paid vacation begins to accumulate from Day One, then the simple answer would be to divide $210K by 52 to find out that Tom is paid $4,038.46 per week. Then, multiply 4 weeks (his annual vacation time) by 7/12th since he worked 7 of the 12 months, and that gives you $9,423.08.
Be prepared for HR to pare that back a bit since there are 52 weeks plus one day in a regular year, plus two days in a leap year....
