The True Cost of Mortgage Refinancing

Back to Blog
Refinancing your mortgage can be one of the smartest financial moves you make, if you do it for the right reasons and look beyond just the interest rate. While many homeowners focus on the advertised rate, lender fees and closing costs play a major role in determining whether refinancing actually saves you money.

When you refinance, you replace your existing mortgage with a new one, ideally at a lower interest rate. This can reduce your monthly payment, lower the total interest you pay overtime, or both. However, these benefits come with costs. Just like when you purchase a home, refinancing includes closing costs charged by the lender. These may include application fees, appraisal fees, title work, and lender fees. How those fees are structured can significantly affect how long it takes to break even, meaning the point when your savings outweigh the cost of refinancing.
 

Credit Unions: A better Deal on Fees

One important detail borrowers often overlook is how closing costs are calculated. Some lenders charge fees as a percentage of your loan amount. For example, a lender charging 2 percent on a $300,000 refinance would add $6,000 in closing costs before other fees are even considered. Michigan First Credit Union takes a different approach by using a flat fee structure. This means the fee stays the same regardless of loan size, which can save borrowers thousands of dollars upfront. If your goal is to save money through refinancing, choosing a lender with predictable, lower fees can help you reach your break-even point much sooner.
 

How Long Until You Break Even?

Let’s look at a real example:
  • Original mortgage: $300,000 at 7% interest
  • New refinance rate: 6% on a 30-year fixed
  • Monthly savings from refinance: approximately $200 per month

Now compare two lenders:
 
Lender Type Closing Cost Break-Even (Months)
Traditional lender (2%) fee $6,000 30 months (~2.5 years)
Credit union (flat $1,350) $1,350 ~7 months

Here’s how the math works:
  • Saving $200 per month means each month you recoup $200 in savings
  • With $6,000 in closing costs, it takes about 30 months to break even
  • With $1,350 in flat fees, the break-even point drops to just six to seven months
In this scenario, refinancing with a credit union not only costs less upfront, it delivers net savings much sooner.
 

What You Should Do Before Refinancing

When evaluating a refinance:
  • Requesting loan estimates from multiple lenders and comparing both the interest rate and total closing costs
  • Ask whether lender fees are flat, or percentage based
  • Calculate your break-even point by dividing total costs by your monthly savings
  • Think about how long you plan to stay in your home. If you expect to move before reaching the break-even point, refinancing may not make sense, even with a lower rate
 

What Closing Costs Mean for Your Savings

A lower interest rate is important, but closing costs matter just as much. Working with a lender that offers lower, flat fees, such as many credit unions, can help you reach your savings goals faster and keep more money in your pocket. When refinancing, do not just chase the lowest rate. Take the time to evaluate the full financial picture.
