Fixed vs Variable Mortgage Rate: Which Is Better?
Complete comparison of fixed vs variable mortgage rates. Understand the pros, cons, and which option suits your financial situation.
Fixed vs Variable Rate: Which Should You Choose?
Choosing between a fixed and variable mortgage rate is one of the most important financial decisions you will make. Here is a clear breakdown.
Fixed Rate — Predictability Comes at a Price
A fixed rate guarantees your monthly payment will not change for a set period, regardless of market fluctuations.
Pros: Payment certainty, protection from rate hikes, easy budgeting
Cons: Higher initial rate (typically 0.5-1% above variable), early repayment charges may apply
Best for: Risk-averse borrowers, first-time buyers, those on tight budgets
Variable Rate — Lower Cost, Higher Flexibility
A variable rate follows market conditions. You benefit when rates fall but face higher payments when they rise.
Pros: Lower starting rate, no early repayment penalties, more flexible
Cons: Payments can increase unexpectedly, harder to budget long-term
Best for: Those who can absorb payment fluctuations or plan to sell/refinance within a few years
Comparison Example
On a €250,000 mortgage over 30 years:
Fixed at 5.5%: ~€1,419/month, total ~€511,000
Variable at 4.5%: ~€1,267/month, total ~€456,000 (if rate stays constant)
Risk: If variable rises to 6.5%, payment becomes ~€1,580/month
A hybrid strategy — fix for 3-5 years then switch to variable — can offer a good balance.
Frequently Asked Questions
What is a fixed mortgage rate?▼
A fixed mortgage rate stays the same for a set period — typically 2, 3, 5, 7, or 10 years. During this period your monthly payment remains constant regardless of what happens to market interest rates. This provides predictability and protects you from rate increases.
What is a variable mortgage rate?▼
A variable (or floating) rate changes periodically based on a reference rate (like EURIBOR or a central bank rate) plus a fixed margin set by the lender. Your payments can go up or down over time. Variable rates are typically lower than fixed rates initially.
Which is cheaper overall — fixed or variable?▼
Historically, variable rates tend to be cheaper over the full loan term because they start lower and you benefit when rates drop. However, fixed rates offer protection against rate spikes. The trade-off is paying a premium (usually 0.5-1% more) for the security of knowing exactly what you will pay each month.
What happens when my fixed-rate period ends?▼
When the fixed period expires, the loan typically switches to a variable rate based on the lender's standard variable rate or a reference rate plus a margin. At this point, you have the option to refinance with a new fixed-rate deal, either with your current lender or by switching to a different one.
Can I switch from a variable rate to a fixed rate?▼
Yes, in most cases you can refinance your mortgage to switch from a variable to a fixed rate. This involves applying for a new mortgage deal, which may come with some costs (arrangement fees, valuation fees). Use our calculator to compare the total costs of both options before making a decision.
