Every refinance has a cost — typically 2-5% of the loan amount in closing costs. Whether refinancing makes sense depends entirely on one question: how long will it take for your monthly savings to cover those costs? That's your break-even point, and it's the single most important number in any refinance decision.
This is the short version. For the full walkthrough, including when a cash-out refinance changes the math and how to weigh a shorter term, read Should You Refinance? Pros, Cons, and Break-Even.
The math is straightforward. Divide your total closing costs by your monthly payment savings. If closing costs are $8,000 and you save $200/month, your break-even is 40 months — about 3.3 years. If you plan to stay in the home longer than that, refinancing makes financial sense. If you might sell or move before then, it doesn't.
Your rate is meaningfully above what you could get today. The wider the gap between your current rate and a new one, the faster you reach break-even. You have an adjustable-rate mortgage coming out of its fixed period. You want to eliminate PMI — if your home has appreciated and you're above 20% equity. You want to shorten your term — moving from 30 to 15 years saves tens of thousands in interest. You need cash for a major expense, renovation, or investment.
You're planning to sell within 2-3 years. You won't hit break-even. Your rate is already competitive. Don't chase a marginal improvement that closing costs will swallow. You'd be restarting a 30-year clock when you're 15 years into your current mortgage — unless you refinance to a shorter term. The closing costs outweigh the benefit.
