Refinancing your mortgage to a 15-year term can offer significant savings on interest payments compared to a 30-year loan. This calculator helps you estimate your potential monthly payments, total interest paid, and savings when comparing a 15-year refinance to your current mortgage.
How to Refinance Your Mortgage
Refinancing involves replacing your current mortgage with a new one, typically with better terms. For a 15-year refinance, you're essentially shortening the loan term while maintaining the same loan amount. Here's the general process:
- Check your credit score and debt-to-income ratio to ensure you qualify
- Compare current rates with new rates from lenders
- Choose between a rate-and-term refinance or cash-out refinance
- Apply for pre-approval from multiple lenders
- Select the best offer and complete the refinancing process
- Receive closing costs and pay off your old mortgage
Important Considerations
Before refinancing, carefully evaluate the closing costs, which typically range from 2% to 5% of the loan amount. Also consider whether you'll save enough on interest payments to justify the costs.
Benefits of a 15-Year Refinance
A 15-year mortgage offers several advantages over longer-term loans:
- Lower monthly payments: Shorter loan terms mean you pay less each month
- Faster payoff: You'll own your home sooner and avoid years of interest payments
- Potential tax benefits: You may qualify for mortgage interest deductions
- Reduced interest costs: Lower interest rates can save thousands over the life of the loan
- Improved cash flow: More disposable income each month
However, shorter loan terms also mean you'll pay more in total interest over time compared to a 30-year mortgage. Use this calculator to determine if the savings justify switching to a 15-year term.

Calculator Limitations
This calculator provides estimates only. Actual results may vary based on your specific financial situation and the terms offered by lenders. Always consult with a mortgage professional before making refinancing decisions.
Calculation Formula
The calculator uses the standard mortgage payment formula to estimate your monthly payments:
The calculator then compares this 15-year payment with your current monthly payment to show potential savings.
Worked Example
Let's look at an example to see how a 15-year refinance might work for you:
| Scenario | Loan Amount | Interest Rate | Term | Monthly Payment | Total Interest |
|---|---|---|---|---|---|
| Current 30-year mortgage | $250,000 | 4.5% | 30 years | $1,432.76 | $156,466 |
| 15-year refinance | $250,000 | 3.5% | 15 years | $1,825.49 | $108,847 |
In this example, while the monthly payment increases by $392.73, the total interest paid over 15 years is significantly less ($108,847 vs. $156,466). The refinance saves $47,619 in interest over the life of the loan.
Frequently Asked Questions
How much can I save with a 15-year refinance?
Savings depend on your current interest rate, the new rate you qualify for, and your loan amount. Generally, you can save thousands in interest payments over the life of the loan, though you'll pay more each month. Use our calculator to estimate your specific savings.
What are the closing costs for refinancing?
Closing costs typically range from 2% to 5% of the loan amount. These may include appraisal fees, title insurance, origination fees, and other charges. Be sure to factor these costs into your decision-making process.
Can I refinance if I have bad credit?
It's more difficult to refinance with bad credit, but not impossible. Some lenders specialize in helping borrowers with less-than-perfect credit scores. You may need to pay higher interest rates or closing costs to qualify.
How long does refinancing take?
The refinancing process typically takes 30 to 45 days from application to closing. This includes time for loan approval, document preparation, and the closing process itself.
Should I refinance if my home value has decreased?
Refinancing when your home value has decreased can be risky. You may be required to put down more money to avoid defaulting on the loan. It's generally better to wait until your home's value has increased before refinancing.
