What Results You’ll Get

After entering your details, the tool calculates:

• New monthly mortgage payment
• Monthly savings (or increase)
• Total interest paid on new loan
• Interest savings compared to current loan
• Break-even point in months

How the Calculation Works

Mortgage payments are calculated using the standard amortization formula:

Monthly Payment = P × [r(1+r)^n] / [(1+r)^n − 1]

Where:

• P = Loan amount
• r = Monthly interest rate
• n = Total number of payments

The calculator compares your current mortgage with the proposed refinance loan and determines financial impact.

Practical Example

Let’s assume:

• Current balance: $250,000
• Current rate: 6.5%
• Remaining term: 25 years
• New rate: 5.5%
• New term: 25 years
• Closing costs: $4,000

Results may show:

• Monthly payment reduction: $150
• Break-even: 27 months
• Total savings over loan: $40,000+

This means if you stay in your home longer than 27 months, refinancing is beneficial.
