What is a Home Loan Refinance?
Refinancing a home loan involves replacing your existing mortgage with a new one—usually with better terms such as a lower interest rate or a different repayment period. The goal is to either reduce monthly payments, save on interest over time, or switch from an adjustable-rate mortgage (ARM) to a fixed-rate one.
Purpose of the Home Loan Refinance Calculator
Our Home Loan Refinance Calculator is designed to help you:
- Determine the break-even point for your refinancing cost
- Compare total interest costs between current and refinanced loans
- Estimate monthly savings
- Understand whether refinancing aligns with your financial goals
How to Use the Home Loan Refinance Calculator
Using the calculator is straightforward. Here’s how to get the most accurate results:
Input Fields:
- Current Loan Amount – Enter the remaining balance on your current mortgage.
- Current Interest Rate (%) – Your current mortgage rate.
- Monthly Payment – What you’re currently paying each month.
- Remaining Term (Years) – Number of years left on your existing mortgage.
- New Loan Amount – Typically the same as the current loan amount unless you’re borrowing more/less.
- New Interest Rate (%) – The rate offered on the refinanced mortgage.
- New Loan Term (Years) – The number of years for the new loan.
- Closing Costs – Any fees associated with the refinance process.
Output Details:
- New Monthly Payment
- Monthly Savings
- Total Interest Saved
- Break-even Period
Formula Used in Refinance Calculation
Here’s how the calculator computes the values step-by-step:
Monthly Payment Formula:
iniCopyEditM = P * r * (1 + r)^n / ((1 + r)^n – 1) Where:
- M = monthly payment
- P = loan principal (amount borrowed)
- r = monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = total number of payments (years × 12)
Interest Savings:
sqlCopyEditTotal Interest (Current) = Monthly Payment × Remaining Months - Current Loan Amount Total Interest (New) = New Monthly Payment × New Term Months - New Loan Amount Interest Savings = Total Interest (Current) – Total Interest (New) Break-even Point:

Let’s look at a real-world example to demonstrate how the calculator works.
Input:
- Current Loan Amount: $200,000
- Current Interest Rate: 5.5%
- Monthly Payment: $1,135
- Remaining Term: 25 years
- New Loan Amount: $200,000
- New Interest Rate: 4%
- New Loan Term: 25 years
- Closing Costs: $3,000
Output:
- New Monthly Payment: $1,056
- Monthly Savings: $79
- Interest Savings Over Loan Term: $23,700
- Break-even Period: 38 months
This tells us the refinance will begin saving you money after a little over 3 years and result in long-term savings of over $20,000.
