Refinancing to A 15 Year Mortgage Calculator

Refinancing your mortgage to a 15-year term can significantly reduce your monthly payments and save you money over the life of the loan. This calculator helps you estimate the potential savings and costs of switching from your current mortgage to a 15-year term.

Why Refinance to a 15-Year Mortgage?

Refinancing to 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 can pay off your mortgage in about half the time of a 30-year loan.
Potential tax benefits: You may be able to deduct mortgage interest and points.
Improved cash flow: More money each month can help with other financial goals.

However, refinancing also has costs, including closing costs and potential fees. It's important to carefully compare the pros and cons before deciding.

How the Calculator Works

This calculator estimates the potential savings and costs of refinancing to a 15-year mortgage by comparing your current mortgage payments with what you would pay on a new 15-year loan.

Monthly Payment Formula

The monthly payment for a mortgage is calculated using the formula:

M = P [ i(1 + i)ⁿ ] / [ (1 + i)ⁿ - 1 ]

Where:

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

The calculator uses this formula to estimate your current and potential new monthly payments, then compares the two to show your potential savings.

Example Calculation

Let's look at an example to see how refinancing to a 15-year mortgage could save you money.

Example Scenario

Current mortgage:

Loan amount: $200,000
Interest rate: 5% (0.4167% monthly)
Term: 30 years
Monthly payment: $1,073.64

Potential new 15-year mortgage:

Loan amount: $200,000
Interest rate: 4.5% (0.375% monthly)
Term: 15 years
Monthly payment: $1,486.64

In this example, refinancing would increase your monthly payment by $413.00 but pay off your loan in just 15 years instead of 30.

This example shows that while refinancing to a 15-year term would increase your monthly payment, you would save significantly on interest and pay off your loan much faster.

Key Factors to Consider

Before refinancing to a 15-year mortgage, consider these important factors:

Factor	Consideration
Closing costs	Refinancing typically costs 2-5% of the loan amount in closing costs.
Interest rate	Compare current rates with potential new rates to ensure you're saving money.
Loan term	15-year terms are shorter, so you'll pay off the loan faster but with higher monthly payments.
Credit score	You may qualify for better rates with a higher credit score.
Cash flow	Consider whether you can afford higher monthly payments.

Weighing these factors can help you make an informed decision about whether refinancing to a 15-year mortgage is right for you.
