Mortgage Refinance: When Should You Refinance and How Does It Work?

Rate-and-Term vs Cash-Out Refinance

Rate-and-Term Refinance: This is the most common type of refinance. You replace your current mortgage with a new one that has a lower interest rate, a different loan term (e.g., switching from a 30-year to a 15-year mortgage), or both. The goal is to reduce your monthly payment or pay off your loan faster. Closing costs for rate-and-term refinances are typically the lowest because the loan amount stays the same as your remaining balance. Most borrowers choose this when interest rates have dropped at least 1% to 2% below their current rate. The math is straightforward: calculate the monthly savings, divide the closing costs by that amount, and determine if you will stay in the home long enough to break even.

Cash-Out Refinance: Here you take out a new mortgage for more than you currently owe and receive the difference as cash at closing. For example, if you owe $200,000 on a home worth $400,000, you could refinance with a $280,000 loan and walk away with $80,000 in cash (minus closing costs). Cash-out refinances typically have slightly higher interest rates than rate-and-term refinances because the lender is taking on more risk. The cash can be used for home renovations (which may increase your property value), consolidating high-interest debt, or investing. Most lenders cap cash-out at 80% of your home's value. The risk is that you increase your loan balance and monthly payment, so the cash should be used for something with a strong expected return. Check your credit score before applying →

The Break-Even Calculation

The break-even period is the single most important number when evaluating a refinance. It tells you how many months it will take for the monthly savings to overcome the closing costs. The formula is simple: break-even = total closing costs / monthly savings. If closing costs are $5,000 and your monthly savings are $200, your break-even is 25 months. If you plan to stay in the home longer than 25 months, refinancing makes financial sense. If you plan to move or sell before 25 months, you will lose money.

Closing costs for a refinance typically range from 2% to 5% of the loan amount. On a $250,000 loan, expect to pay $3,000 to $7,500. These costs include the application fee, origination fee, appraisal fee, title search and insurance, attorney fees, recording fees, and prepaid interest. Some lenders offer "no-closing-cost" refinances, but this usually means the costs are rolled into the loan balance or offset by a higher interest rate. Always ask for a Loan Estimate document from multiple lenders and compare the total costs, not just the interest rate. The difference of 0.25% in rate or $1,000 in fees can significantly change your break-even calculation. Explore real estate investing strategies →

Current Rate Environment Considerations

As of 2026, mortgage rates are significantly higher than the historic lows of 2020–2021. If you currently have a 3% mortgage from that period, refinancing to current rates of 6% to 7% would increase your monthly payment substantially. In this environment, a rate-and-term refinance likely does not make sense for borrowers with sub-4% mortgages. However, a cash-out refinance might still be worth considering if you need capital for debt consolidation, home improvements, or investment purposes — as long as you are comfortable with the higher payment.

For borrowers with higher existing rates — say 6.5% or above — a refinance to a current rate of 5.0% can produce meaningful savings. The 1% to 2% drop rule of thumb still applies: you generally want rates to be at least 1% to 2% below your current rate for a refinance to be worthwhile. But even a 0.5% drop can make sense if your loan balance is large enough or if you plan to stay in the home for many years. Always run the break-even calculation with your specific numbers before making a decision. Start here with our beginner's investing guide →

When should I NOT refinance?

Do not refinance if you plan to move or sell the home within the break-even period — you will never recoup the closing costs. Avoid refinancing if you have a low interest rate from 2020–2021 (e.g., 3% or lower) and current rates are higher. Also think twice if you have poor credit (below 620 FICO) because you may not qualify for a rate that makes refinancing worthwhile. Finally, do not refinance to consolidate debt if you have not addressed the underlying spending habits — you risk running up new debt on top of the refinanced loan.

What is a no-closing-cost refinance?

A no-closing-cost refinance means the lender covers the closing costs in exchange for a higher interest rate. Alternatively, the costs may be rolled into the loan balance. This eliminates the upfront out-of-pocket expense but increases your monthly payment or total interest over the life of the loan. This option makes sense if you plan to sell the home within a few years and want to avoid paying thousands upfront. However, if you plan to stay long-term, paying closing costs upfront and getting a lower rate typically saves you more money.

Can I refinance with bad credit?

Yes, but it may be harder and more expensive. For a conventional refinance, most lenders require a minimum credit score of 620. FHA Streamline Refinance may accept scores as low as 500 if you already have an FHA loan. VA Interest Rate Reduction Refinance Loans (IRRRL) for veterans do not require a credit check. With bad credit, you will likely face higher interest rates, which reduces the potential savings from refinancing. Improving your credit score by paying down debt and correcting errors on your credit report before applying can help you qualify for better rates.

Should I refinance to a 15-year mortgage?

Refinancing from a 30-year to a 15-year mortgage can save you tens of thousands in interest over the life of the loan. The catch is that your monthly payment will be significantly higher because you are paying off the same balance in half the time. For example, refinancing a $250,000 loan from 30 years at 6.5% ($1,580/month) to 15 years at 5.5% ($2,043/month) increases your monthly payment by $463 but saves over $200,000 in total interest. This makes sense only if you have stable income, a robust emergency fund, and your other financial goals (retirement savings, college funds) are on track.
