What is the formula for calculating mortgage refinance break-even?

The simple refinance break-even formula is: Break-Even Period (Months) = Total Refinance Closing Costs / Monthly Payment Savings. For example, if closing costs total $6,000 and your monthly principal and interest payment drops by $200: $6,000 / $200 = 30 months (2.5 years) to break even.

What are typical closing costs when refinancing a home mortgage?

Mortgage refinance closing costs generally range between 2% and 5% of the total loan amount. On a $400,000 mortgage, closing costs typically fall between $8,000 and $16,000, covering lender origination fees, home appraisal, title search, attorney fees, and recording taxes.

When does refinancing NOT make financial sense?

Refinancing is inadvisable if you plan to sell the home or relocate before reaching your break-even month. Additionally, if you are 12 years into a 30-year mortgage and refinance into a new 30-year loan, you may lower your monthly bill but pay substantially more total interest over time.

What is a 'no-closing-cost' mortgage refinance?

In a 'no-closing-cost' refinance, the lender does not eliminate fees. Instead, the lender either rolls the closing costs directly into your new loan balance (increasing the principal you owe) or charges a slightly higher interest rate in exchange for a lender credit that covers upfront fees.

How does refinancing from a 30-year to a 15-year mortgage affect interest?

Refinancing into a 15-year mortgage typically secures an interest rate 0.5% to 0.75% lower than 30-year rates. While your monthly payment may increase due to the accelerated principal repayment, you can cut total lifetime interest payments by 55% to 65% and build equity twice as fast.
