Should I Refinance to 15 Year Mortgage Calculator

Reviewed by Calculator Editorial Team

Deciding whether to refinance your mortgage to a 15-year term can significantly impact your long-term financial situation. This calculator helps you evaluate the potential savings and costs of switching to a shorter-term loan.

When to Refinance to a 15-Year Mortgage

Refinancing to a 15-year mortgage might be beneficial in several scenarios:

  • Lower interest rates: If current interest rates are significantly lower than your existing mortgage rate, you could save thousands over the life of the loan.
  • Debt consolidation: If you have high-interest debt, refinancing could help you pay it off faster while reducing your overall interest costs.
  • Cash-out refinance: If you need funds for home improvements or other expenses, a cash-out refinance might make sense.
  • Early payoff: If you plan to sell your home soon, refinancing to a 15-year term could help you pay off the mortgage faster.

Before refinancing, consider closing costs, loan terms, and how the change will affect your overall financial plan.

How the 15-Year Refinance Works

A 15-year mortgage typically offers lower monthly payments compared to a 30-year mortgage, but the interest costs are higher over the life of the loan. Here's how it works:

Monthly Payment 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 (15 years × 12 = 180 months)

Key considerations when refinancing to a 15-year term:

  • Closing costs: Refinancing typically involves fees that can range from 2% to 5% of the loan amount.
  • Interest savings: The shorter term means you'll pay more in interest over the life of the loan.
  • Cash flow: Lower monthly payments could free up cash for other expenses.
  • Home equity: Refinancing can access your home's equity, which could be used for improvements or other financial goals.

Real-Life Examples

Let's compare a 15-year and 30-year mortgage for a $200,000 loan at 5% interest:

Term Monthly Payment Total Interest Paid Total Cost
15 years $1,387.76 $106,267.60 $306,267.60
30 years $995.44 $124,664.80 $324,664.80

In this example, the 15-year mortgage has lower monthly payments but higher total interest costs. The decision depends on your financial goals and situation.
