The pros and cons of variable and fixed-rate mortgages

More and more people are opting for fixed rates over variable rates because they offer stability and peace of mind. That being said, there are pros and cons to each type of rate.

You might know the difference between a variable and a fixed-rate mortgage (if you don’t, click here) but do you know the advantages and disadvantages of each? And do you know which rate would be best suited to your needs?

In this guide, we discuss the pros and cons of variable and fixed-rate loans and also look at why more and more people seem to be opting for fixed-rate loans these days.  

Variable rates


Flexibility is definitely the greatest asset to a variable rate. You don’t need to worry about penalties if you want to increase your monthly mortgage repayment, pay off your mortgage early, or switch to another lender and you could also benefit from falling ECB interest rates (if your lender responds to them).     


Variable rates don’t offer stability or predictability, meaning you're at the mercy of changing rates. Yes, your rate might go down over the term of your mortgage but equally it could go up! Rate changes are difficult to predict and a lot can happen over a 20 or 30-year mortgage term so you could be putting yourself in a financially vulnerable position by choosing to go with a variable rate.

Fixed rates


Fixed-rate mortgages bring certainty, and that can be worth a lot to many house-hunters. Mortgage repayments tend to be the biggest monthly outgoing for most households so knowing exactly what you’re going to be paying every month for a fixed period of time can bring peace of mind and really help with budgeting.


If you lock yourself into a fixed rate for say, 20 years, there is a chance that interest rates could fall over that time, leaving you stuck paying more than you otherwise would have. Another drawback of a fixed-rate mortgage is that you may be hit with penalty fees if you want to increase your monthly repayments at any stage. 

If you receive a lump sum and want to use it to knock a chunk off your mortgage, you may also be charged an "additional funding fee" for doing so. These fees don’t apply to variable-rate mortgages. However some banks now allow you make an overpayment of up to 10% of your outstanding balance each year without being penalised.

Similarly, you may be charged a breakage fee if you switch lenders or switch to a variable rate with your existing lender before your fixed-rate period has ended.

Another important thing when considering a fixed rate is whether you're going to move in the future, as you may incur a penalty here too. Some lenders will allow you carry your rate and mortgage balance to a new property, but it would mean that in order to avoid any penalty, you must stay with that lender.

Basically, if you’re committing to a fixed rate, it may only be worth it if you’re happy to stick to that rate and repayment for the agreed term while staying in the same property.

Fixed rates, particularly those longer than 10 years, are also usually more expensive than variable rates as you're paying for the extra costs associated with fixing the payment over a number of years. In general the longer the fixed term you choose, the higher the interest rate, so the higher your monthly repayment will be. 

To fix or to vary?

Whether you choose to fix or vary will ultimately come down to several things such as:

  • The value you place on stability and predictability
  • Whether you think you'll want to increase your monthly repayments at some stage in the near future 
  • Whether you think you'll want to pay a lump sum off your mortgage at some stage in the near future  
  • Whether you think you'll want to switch mortgage at some stage in the near future 
  • Whether you think you'll want to move home at some stage in the near future 

Why are more people opting for fixed-rate mortgages in Ireland?

Fixed rates have long been common in the rest of Europe so one could argue that the trend towards fixed rates here has been overdue. 

Recent figures from the Central Bank of Ireland show that over 80% of new mortgages in Ireland are now fixed. This is a huge change from several years ago when around 80% of all new mortgages were on variable rates.  

Fixed rates provide certainty - and in today's world that means a lot to many people.   

Before you decide, always compare!

Taking out a mortgage can be a very stressful and nerve-wracking time. Choosing between a fixed rate or a variable rate is one of a number of key decisions you’ll have to make and it’s important to have all of the information available before committing.

Whatever way you look at it, choosing what rate to go with is going to be a gamble. Irish property prices and global interest rate trends are notoriously difficult to predict, but by knowing the value you place on certainty and peace of mind, you will be in a good position to decide whether you should fix or vary your repayment rate.
