The Break-Even Rule

Refinancing always costs money upfront. The break-even point tells you how many months until your monthly savings cover the closing costs. If you plan to move before that, don't refinance.

The 1% Rate Rule

A common rule of thumb: refinancing is worth it if you can lower your rate by at least 1%. But that depends heavily on how long you plan to stay. Our calculator gives you the exact personalized answer.

The Hidden Trap

Refinancing to a new 30-year term resets your amortization clock. Even at a lower rate, you can end up paying MORE total interest. This calculator exposes that trap clearly.

Should You Refinance Your Mortgage? The Complete Analysis

Mortgage refinancing replaces your current loan with a new one — ideally at a lower interest rate or better terms. It can save significant money, but it's not always the right move. The key questions are: how much do you save monthly, how much does it cost upfront, and how long until you break even?

When Refinancing Makes Sense

Refinancing typically makes sense when: your new rate is at least 0.75–1% lower than your current rate, you plan to stay in the home long enough to break even on closing costs (typically 2–5 years), and you're not resetting to a much longer term that eliminates the interest savings.

The Hidden 30-Year Trap

Many homeowners refinance a loan that has 20 years remaining into a new 30-year loan. Monthly payments drop dramatically, but the total interest paid over the life of the loan can actually increase. Always compare total interest, not just monthly payments.

How much do refinancing closing costs typically run?
Closing costs for a refinance typically run 2–5% of the loan amount. On a $280,000 loan, that's $5,600–$14,000. Some lenders offer "no-closing-cost" refinances where costs are rolled into the rate — you pay a slightly higher rate but nothing upfront.
How long does refinancing take?
A typical mortgage refinance takes 30–45 days from application to closing. Some lenders offer streamlined refinances (especially for FHA/VA loans) that can close in 2–3 weeks.
Can I refinance if my home value dropped?
It's harder but not impossible. If you owe more than your home is worth (underwater mortgage), conventional refinancing is difficult. HARP and FHA Streamline programs exist specifically for underwater homeowners.
