💡 Example: See the Calculator in Action
Let’s say you currently owe $250,000 on your mortgage at a 4.5% interest rate with 25 years remaining.
You’re thinking of refinancing to a 3.5% rate over 30 years, and your closing costs are $5,000.
When you enter these values into the calculator, you’ll see something like this:
| Detail | Old Loan | New Loan |
|---|---|---|
| Monthly Payment | $1,389.35 | $1,122.61 |
| Monthly Savings | $266.74 | |
| Break-even Point | ~19 months | |
| Total Interest Saved | $37,000+ (after closing costs) |
👉 That means after around 1 year and 7 months, your refinancing starts saving you real money.

🧠 Why Refinancing Can Be a Smart Move
Refinancing can help you:
- Lower your monthly payment and increase savings.
- Switch from an adjustable-rate to a fixed-rate mortgage.
- Tap into home equity for renovations or debt consolidation.
- Shorten your loan term and save on interest over time.
But it’s not always the right move — especially if you’re close to paying off your loan or plan to move soon. That’s why this calculator is invaluable for previewing your potential gains (or losses).
