A: You don't need a budget—you need a reality check. Something isn't adding up. Your combined income is $7,250 a month; even in a state with a high income tax rate, your combined take-home pay is probably about $5,000 a month. I'm guessing that your nonmortgage bills eat up $1,100, so that leaves $3,900 for your mortgage and other living costs. You told me the rate on your mortgage but not the monthly cost. Why? Are you in a house you can't afford? At 8 percent, a $400,000 30-year mortgage would run you $3,000 a month—leaving not much money for food.
People with FICO credit scores of 700-plus have been locking in fixed-rate mortgages of no more than 6 percent. The fact that you are paying 8 percent tells me something's wrong somewhere, as does your fiancé's $24,000 in debt. And that's really the issue here, right? You were doing fine until you combined finances, but now your guy's poor money habits are dragging you down.
No budget on earth will work until you and your fiancé have a series of heart-to-hearts about your finances. For tips on how to do so, see Financial Couples' Therapy .
