Real-Life Examples

Example 1: Refinancing a Point Lower

A $300,000 mortgage at 6.5% ($1,896.20 a month) is refinanced at 5.5% ($1,703.37) for $4,500 in closing costs.

Given

ClosingCosts = $4,500.00OldPMT = $1,896.20NewPMT = $1,703.37

Step-by-Step

1.Monthly saving = 1,896.20 − 1,703.37 = $192.83
2.Break-even = 4,500 / 192.83
3.Break-even in months ≈ 23.34
Result:23.34

The refinance pays for itself in under two years. Staying in the home longer than that makes it a clear win.

Example 2: Larger Loan, Smaller Rate Cut

A $500,000 mortgage at 6% ($2,997.75) refinanced at 5% ($2,684.11) for $6,000 in costs.

Given

ClosingCosts = $6,000.00OldPMT = $2,997.75NewPMT = $2,684.11

Step-by-Step

1.Monthly saving = 2,997.75 − 2,684.11 = $313.64
2.Break-even = 6,000 / 313.64
3.Break-even in months ≈ 19.13
Result:19.13

Just over a year and a half. The bigger the balance, the more a given rate cut saves each month and the faster costs are recovered.

Frequently Asked Questions

Not by itself. Resetting a loan to a new 30-year term can lower the payment while raising lifetime interest. Compare Total Interest Cost on both loans, not just the payments.

Yes. Financed costs are still costs; they simply appear as a higher balance and payment on the new loan.
