When Does Refinancing a Mortgage Make Sense?
The refinance calculator helps you quickly determine whether the math supports refinancing your current mortgage. Refinancing replaces your existing loan with a new one — typically at a lower interest rate, a different term, or both. The decision hinges on two things: how much you save each month and how long it takes to recover the closing costs.
The Break-Even Rule
The break-even point is the key metric for any refinance decision. Divide total closing costs by your monthly savings to find the break-even month. If you plan to stay in the home (or keep the loan) for longer than that, refinancing puts money in your pocket. If you might sell or refinance again before then, the upfront costs could outweigh the savings.
Rate Drop Guidelines
A common rule of thumb is to refinance when rates drop at least 1 percentage point below your current rate. However, this rule is outdated for today's higher-balance loans. Even a 0.5% drop on a $400,000 loan can produce enough monthly savings to recoup $5,000 in closing costs in under three years. Use the actual numbers rather than rule-of-thumb shortcuts.
Term Considerations
Refinancing into a shorter term (15 years vs. 30) dramatically reduces total interest paid and builds equity faster, but the monthly payment will be higher. Refinancing into a longer term lowers your payment but costs more over time. If your goal is cash flow relief, extend the term. If your goal is long-term savings and you can afford the higher payment, shorten it.
No-Closing-Cost Refinances
Some lenders offer refinances with no upfront closing costs by rolling costs into the loan balance or accepting a slightly higher rate. These can make sense if you plan to sell within a few years and want to avoid break-even risk. Enter $0 closing costs in this calculator to model that scenario.
Cash-Out Refinancing
A cash-out refinance lets you borrow against your home equity by refinancing for more than you currently owe and taking the difference in cash. This can fund renovations, debt consolidation, or other large expenses. Note that cash-out refinances typically carry slightly higher rates than rate-and-term refinances and increase your loan balance.
