No way for us to know. Depends on how much more you need to have withheld by the end of the year.
(VERY ROUGHLY) For a person being paid twice a month at 2000 gross per paycheck
Withholding/paycheck for married and zero allowances is $165
Withholding/paycheck for single and zero allowances is $240
so ~$75 more per paycheck is withheld by going from M to Single and zero allowances on both.
IF you were doing Married and 2 allowances last year and switched to Single and 2
then it goes from 125-to-170 or $45 more per pay

So you should be able to figure out from that ~how much the extra withholding will add in to your total by the end of the year.
(But, of course, that's for ~2000 gross /paycheck twice a month)
