This Refinance Calculator is an advanced mortgage tool designed to help homeowners determine if switching to a new loan offer makes financial sense. By comparing your current debt structure against new market rates, it provides a data-driven analysis of your potential savings.
How to Use the Refinance Calculator
Step 1: Enter Current Loan Data
Start by inputting the details of your existing mortgage to establish a baseline for comparison.
-
Remaining Balance: The total amount you still owe the bank.
-
Interest Rate: Your current fixed or variable APR.
-
Remaining Term: How many years are left until the loan is fully paid off.
-
Extra Monthly Payment: If you are currently paying more than the minimum, include it here to see how it affects your current payoff timeline.
Step 2: Input New Loan Offer
Enter the terms of the refinance offer you are considering.
-
New Interest Rate: The target rate offered by the lender.
-
New Term: Select a new duration (10, 15, 20, or 30 years). Note that shortening your term usually increases your monthly payment but significantly reduces total interest paid.
-
Closing Costs: Refinancing isn't free. Enter the estimated fees (typically 2%–5% of the loan amount).
-
Roll In vs. Pay Upfront: Decide if you want to pay the closing costs out of pocket or add them to the total balance of your new loan.
Step 3: Analyze the Results
The tool focuses on four Key Performance Indicators (KPIs):
-
New Payment: Your projected monthly principal and interest.
-
Monthly Savings: The immediate impact on your monthly cash flow.
-
Breakeven Point: Perhaps the most important metric; this tells you exactly how many months it will take for your monthly savings to "pay back" the initial closing costs.
-
Lifetime Δ: The total amount of interest you will save (or lose) over the entire life of the loan.
Understanding the "Breakeven" Concept
The calculator includes a Breakeven Progress Bar. If you plan to move out of your home before reaching this point, refinancing may actually cost you more money than it saves, even if the interest rate is lower.
