Expert Tip

Refinancing makes financial sense if you plan to stay in the home longer than the calculated break-even period.

How this Calculator Works

This calculator estimates the break-even month and net savings when refinancing a home mortgage. It compares refinancing closing costs against the monthly payment savings to determine when the move becomes profitable.

Formula & Methodology

Monthly Savings = Current Monthly Payment - Refinanced Monthly Payment Break-Even Months = Refinancing Closing Costs / Monthly Savings

Step-by-Step Calculation Example

Here is a step-by-step example showing how the calculations are performed:

A homeowner pays $3,000 in closing costs to refinance, lowering their monthly payment from $1,800 to $1,650. 1. Calculate monthly savings: $1,800 - $1,650 = $150. 2. Divide closing costs: $3,000 / $150 = 20 months. Result: The refinance break-even period is 20 months.

FAQ

What is Capitalization Rate (Cap Rate) in real estate?
Cap Rate = Net Operating Income (NOI) / Current Property Value. It measures an unleveraged property's natural rate of return independent of debt financing.
How does Cash-on-Cash Return differ from Cap Rate?
Cash-on-Cash Return calculates Annual Net Pre-Tax Cash Flow divided by Total Out-of-Pocket Cash Invested (down payment + closing costs + rehab). It incorporates debt leverage effects.
What DTI ratio limits do mortgage lenders enforce?
Most conventional lenders prefer a front-end housing DTI under 28% and a total back-end debt DTI under 36% to 43% (up to 50% for FHA/VA backed loans).
