What This Page Covers
A fixed-rate mortgage locks in the same interest rate for the entire loan term. A variable-rate mortgage (adjustable-rate) changes periodically based on a benchmark rate like EURIBOR or the prime rate.
How It Applies
Fixed: $300,000 mortgage at 6.5% for 30 years = $1,896/month, always. Variable: Same mortgage starting at 5.5% = $1,703/month, but could rise to 8% = $2,201/month. The risk is rate increases; the reward is lower initial payments.
Details
Fixed rates provide certainty and are best when rates are low and expected to rise. Variable rates offer lower initial payments and are better when rates are high and expected to fall.
Context
In Spain, most mortgages are variable (EURIBOR + spread). In Germany, fixed rates dominate (10-20 year fixes). In the US, 30-year fixed is the standard. In the UK, 2-5 year fixed terms are common, reverting to variable afterward.
Frequently Asked Questions
When is a fixed rate the safer choice?
A fixed rate suits a borrower who needs a predictable monthly payment and protection if rates rise. You pay for that certainty with a slightly higher starting rate than a variable loan would offer.
What makes a variable rate cheaper at the start?
A variable rate usually starts below the fixed rate because the lender passes on a lower benchmark. The trade-off is that the payment can rise when that benchmark rises.
How often does a variable mortgage rate change?
Most variable mortgages are revised every 6 or 12 months, when the benchmark is republished. The fixed spread stays the same; only the benchmark part of the rate moves.
Can I switch from a variable to a fixed rate later?
Often you can, by refinancing or converting with the same lender. Check the early-repayment or conversion fees first, because they can outweigh the benefit of the switch.
