15 Year Refi Calculator

Use our 15 year refi calculator to determine if refinancing your mortgage to a 15-year term could save you money. Compare your current mortgage payments with potential 15-year refinance payments, factoring in interest rates, loan amounts, and closing costs.

What is a 15-year refinance?

A 15-year refinance is a process where you replace your existing mortgage with a new loan that has a 15-year repayment term instead of the original 30-year term. This can potentially lower your monthly payments and reduce the total interest paid over the life of the loan.

Benefits of a 15-year refinance

Lower monthly payments compared to a 30-year mortgage
Potential savings on total interest paid
Faster payoff of your mortgage
Potential tax benefits from interest deduction
Opportunity to take cash out while refinancing

Considerations before refinancing

While a 15-year refinance can offer financial benefits, there are several factors to consider:

Current interest rates - Make sure you're getting a better rate than your existing mortgage
Closing costs - These can offset some of the savings
Credit score - You'll need good credit to qualify
Loan term - A shorter term means you'll pay more in interest over time
Future interest rate changes - If rates rise, your payments may increase

How to use this calculator

Our 15-year refinance calculator is designed to help you estimate your potential savings. Follow these steps to use it effectively:

Enter your current mortgage balance in the "Current Loan Amount" field
Input your current interest rate in the "Current Interest Rate" field
Enter the new interest rate you're considering for your 15-year refinance
Add any estimated closing costs associated with the refinance
Click the "Calculate" button to see your results

The calculator will display your estimated monthly payments, total interest paid, and potential savings compared to your current mortgage.

Formula used

The calculator uses the standard mortgage payment formula to calculate your monthly payments:

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

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate divided by 12)
n = Number of payments (loan term in years × 12)

The calculator then compares the 15-year payment with your current payment and calculates the potential savings, factoring in closing costs.

Example calculation

Let's look at an example to illustrate how the calculator works:

Example Scenario

Current mortgage: $200,000 at 4.5% interest for 30 years

Refinance offer: $200,000 at 3.5% interest for 15 years

Closing costs: $3,000

Using the calculator:

Enter $200,000 as the current loan amount
Enter 4.5% as the current interest rate
Enter 3.5% as the new interest rate
Enter $3,000 as the closing costs
Click "Calculate"

The calculator would show:

Current monthly payment: $1,073.64
15-year refinance payment: $1,372.54
Total interest paid over 15 years: $18,903
Potential savings: $1,101.10 per month

Note that while this example shows potential savings, actual results may vary based on your specific financial situation and market conditions.

Frequently Asked Questions

Is a 15-year refinance right for me?

A 15-year refinance might be right for you if you want to pay off your mortgage faster, lower your monthly payments, or take advantage of lower interest rates. However, consider your financial goals, credit score, and ability to handle higher payments if rates rise. Our calculator can help you estimate potential savings.

How much can I save with a 15-year refinance?

Savings depend on your current mortgage terms, the new interest rate, and closing costs. Generally, you can save hundreds to thousands of dollars per month compared to a 30-year mortgage. Use our calculator to get a personalized estimate based on your specific situation.

What are the closing costs for a 15-year refinance?

Closing costs typically range from 2% to 5% of your loan amount, including fees for appraisal, title insurance, origination, and other charges. These costs can offset some of the savings from lower monthly payments. Our calculator includes a field for closing costs to help you factor them into your decision.

Can I get cash out with a 15-year refinance?

Yes, many lenders offer cash-out refinances that allow you to take out additional funds while refinancing to a 15-year term. However, this can increase your monthly payments and total interest paid. Consider whether the cash is worth the additional cost before proceeding.

What happens if interest rates rise after refinancing?

If interest rates rise after you refinance, your monthly payments may increase. A 15-year term means you'll be paying more in interest over time compared to a 30-year mortgage. Make sure you understand the potential risks before refinancing.
