The Real Impact Of Refinancing Your Mortgage

Understanding the Implications of Refinancing on Your Amortization Schedule

Refinancing your mortgage can offer significant financial benefits, from lowering interest rates to reducing monthly payments or accessing home equity. However, it’s crucial to understand how refinancing impacts your amortization schedule—the timeline and structure of how your loan is paid off over time. This article will explore the key implications of refinancing on your amortization schedule and what it means for your financial goals.

 

1. What Is an Amortization Schedule?

An amortization schedule outlines the breakdown of each monthly mortgage payment into two components: principal and interest. In the early years of a mortgage, payments are primarily applied toward interest, with a smaller portion going to the principal. Over time, the balance shifts, and more of your payment goes toward the principal. You may be surprised to see just how little your payment affects your equity early on, see the graph below for an example:

2. How Refinancing Resets Your Amortization Schedule

When you refinance your mortgage, you’re essentially replacing your existing loan with a new one. This process resets the amortization schedule even if you’ve been paying down your original loan for several years. Here are some important points to consider:

  • Restarting the Clock: Refinancing into a new 30-year mortgage means starting over with a new schedule, where the initial payments are again heavily weighted toward interest.
  • Extended Loan Term: Extending the loan term can reduce monthly payments but may increase the total interest paid over the life of the loan. It's important to consider how much interest you will be saving at the end of the loan.
  • Shorter-Term Options: Opting for a shorter-term loan, such as 15 years, can help you build equity faster and reduce total interest costs, though monthly payments may increase.

3. Impact on Equity Building

The amortization schedule plays a significant role in how quickly you build equity in your home. Refinancing resets this process:

  • Delayed Equity Growth: Restarting a 30-year loan slows down equity accumulation, as the majority of early payments go toward interest. Back to the starting line you go!
  • Accelerated Equity Growth: A shorter-term loan accelerates equity building, as a larger portion of each payment goes toward the principal. This may help keep you in the race if you're far along your mortgage journey but your monthly payment won't be as dramatically different. 

It is essential to consider the impact on equity building when deciding to refinance especially if you are going to rely on your home as a staple of retirement.

4. Total Interest Costs

Refinancing affects the total interest paid over the life of the loan. Here are two ways it can impact your overall wealth:

  • Increased Interest Costs: Restarting a long-term loan means paying more interest in the early years, potentially increasing overall costs if you don’t stay in the home long-term or refinance again within the first few years.
  • Interest Savings: If refinancing lowers your interest rate or shortens your loan term, it can lead to significant savings, even with the reset amortization schedule.
It is important to calculate how much you will be saving by comparing your new monthly savings and the total cost of new the loan plus the costs already incurred on your previous one.

 

5. Aligning Your Loan with Financial Goals

Your amortization schedule should align with your financial goals. Consider the following scenarios:

  • Retirement Planning: If you plan to retire soon, extending your loan term may not align with your goal of being mortgage-free by retirement.
  • Investment Opportunities: Lower monthly payments from refinancing can free up cash for other investments, but ensure this aligns with your overall financial strategy and always measure the cost of refinancing against the expected investment returns. 
  • Future Moves: If you plan to sell your home in a few years, restarting a long-term loan may not make sense. Instead, consider a shorter-term refinance or another financial strategy.
  • Cash out Refi: Refinancing can help you access the equity in your home and use it for purchases such as starting a business or paying off credit card debt. 

Remember to always weight the costs of the refinance with the savings such as paying off high interest debt or the yield of an investment such as starting a business or investment portfolio. 

 

6. Tools to Analyze Amortization Changes

Use online amortization calculators to visualize the impact of refinancing on your loan. Input different scenarios—such as new loan terms, interest rates, and loan amounts—to see how the changes affect your payment breakdown and total costs.


Final Thoughts

Refinancing your mortgage can provide valuable financial benefits, but it is essential to consider the impact of the amortization schedule on equity building when deciding to refinance. If you are in the early stages of your mortgage, you will likely not have paid down much principal and will restart your amortization schedule - pushing off principal payments even further. If you sell again in the short term, you may realize that you have barely paid down any of your principal over 10+ or even 20 years due to multiple refinances. 

ways to mitigate this:

  • Pay extra every month. After you refinance, any extra amounts paid are applied to the principal so it can mitigate the impact of the amortization schedule on your overall wealth and help you pay off the mortgage years early. Consider splitting the difference and paying half of your total saved amount on top of your new monthly payment.
  • Try and refinance only once. You will be in much better shape at the end of your mortgage if you refinance to a lower interest rate but try to only do it once so you don't constantly reset your amortization.
  • Buy down the rate. Buying down the rate will cost more upfront but in a refinance you can work those costs into the loan. You will likely recoup those costs within a few years and will spend the remaining 20+ reaping the rewards as long as you don't refinance again. This should help to limit the need to refinance again in the future.

If you are in the later stages of your mortgage, you are likely paying a significant amount towards your principal which means even if monthly payments are high, you're essentially paying it to yourself and not the bank; think of it as forced savings. Refinancing at the end of the loan is comparable to running a race up hill and getting to the downhill portion before the finish line. But, too tired to go on, you choose to restart the race at a reduced incline instead of just finishing. There are plenty of good reasons for refinancing at this time but consider the implications and try and keep the new loan on a shorter term.

Refinancing CAN and often IS a great decision but remember to arm yourself with knowledge and have all of the facts and implications ready before moving forward.
