How do I know if refinance is beneficial enough to me?
It would help if we had numbers to walk you through the analysis. Current balance, rate, remaining term, and the new mortgage details.  To echo and elaborate on part of Ben's response, the most important thing is to not confuse cash flow with savings. If you have 15 years to go, and refinance to 30 years, at the rate rate, your payment drops by 1/3. Yet your rate is identical in this example.  The correct method is to take the new rate, plug it into a mortgage calculator or spreadsheet using the remaining months on the current mortgage, and see the change in payment. This savings is what you should divide into closing costs to calculate the breakeven. It's up to you whether to adjust your payments to keep the term the same after you close.  With respect to keshlam, rules of thumb often fail. There are mortgages that build the closing costs into the rate. Not the amount loaned, the rate. This means that as rates dropped, moving from 5.25% to 5% made sense even though with closing costs there were 4.5% mortgages out there. Because rates were still falling, and I finally moved to a 3.5% loan. At the time I was serial refinancing, the bank said I could return to them after a year if rates were still lower. In my opinion, we are at a bottom, and the biggest question you need to answer is whether you'll remain in the house past your own breakeven time. Last - with personal finance focusing on personal, the analysis shouldn't ignore the rest of your balance sheet. Say you are paying $1500/mo with 15 years to go. Your budget is tight enough that you've chosen not to deposit to your 401(k). (assuming you are in the US or country with pretax retirement account options) In this case, holding rates constant, a shift to 30 years frees up about $500/mo. In a matched 401(k), your $6000/yr is doubled to $12K/year.  Of course, if the money would just go in the market unmatched, members here would correctly admonish me for suggesting a dangerous game, in effect borrowing via mortgage to invest in the market. The matched funds, however are tough to argue against.
