Break Even quantity is the formula that is used to determine the break-even point. Fixed Costs are those normal costs that are necessary to run any business.

To figure out whether it's in your best interest to refinance, you need to calculate your break-even point. The break-even point is the time it takes to make up in monthly savings what you paid in fees. You calculate it by dividing the mortgage fees by the monthly savings. For example, let's say you would save $100 a month by refinancing, and the closing costs would be $3,000. Your break-even point is 30 months from now: the $3,000 in fees divided by the $100 a month in savings.
