Mortgage Comparison Calculator


Refinancing a mortgage can be an excellent financial decision for many homeowners. By refinancing, you may take advantage of lower interest rates or adjust the terms of your loan to fit better with your goals. But before making any decisions, knowing how much money can be saved through refinancing; that's where a mortgage refinance calculator comes in handy.

What is a Mortgage Refinance Calculator?

A mortgage refinance calculator is an online tool designed to help you estimate potential savings from refinancing your mortgage. Input information about your current loans, such as their amount, interest rate, and remaining term, plus select information about any new loans you are considering. The calculator then estimates your new monthly payment, total interest paid, and time until breakeven on refinancing costs.

Comparing Rates and Fees

A mortgage comparison calculator can help determine which mortgage lender will offer you the best rate and fees. The calculator will consider the amount of your down payment, the loan length, and the interest rate. It will also compare closing costs, points, and other fees associated with the loan. You can understand which lender will offer you the best deal by comparing different mortgage lenders.

Calculating Your Monthly Payment

In addition to helping you compare mortgage lenders, a mortgage comparison calculator can also be used to calculate your monthly payment. The calculator will consider the amount of your down payment, the loan length, and the interest rate. It will then calculate your estimated monthly payment, giving you an idea of what you can expect to pay each month. This can help determine if a specific mortgage is right for you and your budget.




A mortgage comparison formula can be expressed as:

Monthly Payment = P * (r*(1+r)^n)/((1+r)^n-1)


  • P is the principal amount borrowed
  • r is the monthly interest rate (annual interest rate divided by 12)
  • n is the number of monthly payments over the life of the loan

For example, let's say you want to compare two mortgage options:

Mortgage A: $200,000, 30-year term, 4% interest rate. Mortgage B: $200,000, 30-year term, 4.5% interest rate

Using the formula, we can calculate the monthly payment for each mortgage option:

For Mortgage A: P = $200,000 r = 4%/12 = 0.00333 n = 30*12 = 360

Monthly Payment = $954.83

For Mortgage B: P = $200,000 r = 4.5%/12 = 0.00375 n = 30*12 = 360

Monthly Payment = $1,013.37


These factors include:


Interest rates: The interest rate is the percentage of the loan amount charged by the lender. A lower interest rate can save you thousands of dollars over the life of the loan.

Repayment terms: The length of the loan and the frequency of payments can impact your overall cost. A shorter loan term can save you money on interest but will result in higher monthly payments.

Closing costs: Closing costs are the fees associated with obtaining a mortgage, such as an appraisal and origination fees. Be sure to factor in these costs when comparing different loans.

Down payment: The amount you put down upfront can impact your interest rate and monthly payments. A larger down payment can result in lower interest rates and monthly payments.

Loan Type: There are several types of mortgages available, such as fixed-rate, adjustable-rate, and government-backed loans. Each loan type has pros and cons, so it's important to research and compares your options.

Benefits of Using a Mortgage Comparison Calculator

Using a mortgage comparison calculator can provide several benefits, including:


Saving time: A mortgage comparison calculator can provide quick and accurate results instead of manually comparing multiple loan options.

Saving money: By identifying the most affordable loan option, you can save thousands of dollars over the life of the loan.

Empowering decision-making: With the ability to compare and analyze different mortgage options, you can make an informed decision and choose the loan that best fits your needs and goals.
