When Should You Refinance?
Refinancing replaces your current mortgage with a new one, ideally at a lower interest rate. The key question is whether the savings from the lower rate outweigh the closing costs. Our break-even calculator shows exactly how many months it takes to recoup those costs.
The Rule of Thumb
A common guideline is that refinancing makes sense if you can lower your rate by at least 0.5-1% and plan to stay in your home long enough to pass the break-even point. If closing costs are $6,000 and you save $200/month, your break-even is 30 months.
Making Smart Mortgage Decisions
Understanding interest rate mechanics is the foundation of sound financial decision-making. Whether you are borrowing or investing, the rate determines how quickly money grows or how much debt costs over time. Our calculators demystify these calculations and put precise numbers behind decisions that are too often made on rough estimates. Users interested in refinance will find the specifics above most relevant.
