🏠 Refinance Calculator — See If Refinancing Your Mortgage Is Worth It

Just enter your current loan details and the new offer you're considering. Tap Calculate. That's it.

📊 WHAT GETS CALCULATED
🔹 New monthly payment based on the refinance offer
🔹 Monthly savings compared to your current payment
🔹 Lifetime interest savings (net of closing costs)
🔹 Break-even point — how long until closing costs are recovered
🔹 A clear verdict on whether refinancing looks like a good move
All calculations use standard, industry-accepted amortization formulas — the same math your lender uses — so the numbers you see are the numbers you can trust.
