When to Refinance

Rate Drop Rule
Consider refinancing when rates are 0.75-1% lower than your current rate, unless you have a very large loan balance.
Break-Even Point
Only refinance if you plan to stay in the home longer than it takes to recover closing costs through monthly savings.
Loan Term Consideration
Switching to a shorter term can save thousands in interest, but will increase your monthly payment.

Frequently Asked Questions

What is the break-even point?
The number of months it takes for your monthly savings to equal your closing costs. You should stay in the home beyond this point.
Should I roll closing costs into the loan?
Only if you can't afford to pay them upfront and the interest cost doesn't outweigh the refinance benefits.
How much can I save by refinancing?
Savings depend on your loan balance, rate difference, and how long you keep the loan. Use this calculator to see your specific savings.
