If I make 637.50 How much federal will I owe for that 2 weeks?

You really are asking a question that no one but your employer payroll department can possibly give you the correct numbers that you want or need.

You do not have a standard percentage tax deduction amount for this purpose of the withholding amounts from your gross pay for the pay period

The employer payroll department would be the only one that should be able to tell you how much they will be required to withhold from your earnings GROSS salary, wages, etc. for all of the different taxes and other amounts that they are required to withhold from your gross pay before they issue you the NET take home paycheck.

To compare the numbers that you will get from your employer payroll department you can go to www.Paycheckcity.com and you can use the online calculator that is available for your taxes only. Unless you choose some additional deduction amounts that would be withheld you’re your gross amount when using the online calculator at the below enclosed website address

Dear Dew: If it's $95 for Federal it's too much. You are looking at a $1000+ refund next year from Federal. If your wife works or you have another job = all bets are off and I need those numbers also.

You don't provide enough information to answer the question. The answer depends on your deductions claimed on your W-4 at the time you were employed. Also, if you are withholding at the single or married rate.

If you're asking how much you'll have after taxes, I generally calculate at about 15% tax rate. If it's less than, say, $200, I've noticed they take out less of a percentage.

You will need to know your state and your W-4 information.
