When to Refinance
The Rule of Thumb
Refinance when you can lower your rate by 0.5-0.75%+ and will stay long enough to recoup closing costs. Closing costs typically run 2-5% of the loan amount.
Calculate Breakeven
Divide closing costs by monthly savings = breakeven in months. If breakeven is 18 months and you're staying 10 years, refinance. Moving in 12 months? Don't. Our refinance calculator does this math.
Good Reasons
Lower rate, switch ARM to fixed, remove PMI (20%+ equity), shorten term, or cash-out for renovations.
Bad Reasons
Extending term just for lower payments (more interest long-term), cash-out for discretionary spending, or refinancing when nearly paid off.
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. The to refinance context on this page provides additional perspective.
The power of extra payments: Even small additional payments toward principal create outsized, which is why the when to refinance breakdown above goes beyond surface-level statistics to provide the granular detail that supports real decision-making.
Rate shopping strategy: Mortgage rates can vary by 0.5-1.0% between lenders, which underscores why the when to refinance data above matters more than any single rule of thumb when it comes to making informed personal decisions.
Points vs. rate: Paying points (prepaid interest) at closing reduces your, and anyone researching when to refinance will benefit from applying this understanding to the specific situation and figures detailed in the sections above.

When comparing loan options, focus on total cost rather than monthly payment alone. A lower monthly payment often means a longer term and significantly more total interest paid. Our calculator displays both figures prominently so you can weigh the tradeoff between monthly cash flow and long-term cost. Users interested in to refinance will find the specifics above most relevant.
For the most accurate results, use the interest rate from your actual loan offer or pre-approval letter rather than advertised rates, which may require specific credit scores or down payment amounts to qualify for. Also factor in any fees, points, or closing costs that are not reflected in the base interest rate, as these increase your effective cost of borrowing. The to refinance information on this page illustrates these principles directly.
