Overview

The Refinance Calculator helps you determine if switching to a new loan will result in long-term financial savings by comparing your current mortgage terms against potential new rates and associated closing costs.

When to Use

  • When market interest rates drop significantly below your current mortgage rate.
  • When you are considering consolidating debt or taking out equity through a cash-out refinance.
  • When you want to calculate your break-even point to see how long it takes for monthly savings to cover your closing costs.

How It Works

  • Enter your current loan balance, existing interest rate, and the remaining term of your current mortgage.
  • Input the proposed new interest rate, the desired loan term, and the estimated closing costs for the new loan.
  • Optionally include any cash-out amount if you plan to withdraw equity during the refinancing process.
  • Review the calculated monthly payment difference and the total interest savings to decide if refinancing is the right financial move.

Use Cases

Evaluating if a 1% drop in interest rates justifies the upfront cost of refinancing.
Determining if extending your loan term to lower monthly payments is worth the increase in total interest paid over time.
Assessing the financial impact of pulling equity out of your home for renovations or debt consolidation.

FAQ

What is a break-even point in refinancing?

It is the amount of time required for your monthly savings to equal the total closing costs you paid to refinance the loan.

Do I need to include closing costs?

Yes, including accurate closing costs is essential, as these fees significantly impact whether refinancing will actually save you money.

How does a cash-out refinance affect my savings?

A cash-out refinance increases your total loan balance, which may increase your monthly payment and total interest paid, even if the interest rate is lower.

Can I use this for non-mortgage loans?

While designed for mortgages, this calculator can be used for any fixed-rate loan where you are comparing current terms against a new offer.

Does this tool account for tax deductions?

No, this calculator provides a mathematical comparison of loan terms and does not factor in individual tax implications or interest deductions.
