The Impact of Interest Rates on your Mortgage: What You Need to Know
If you’ve been thinking about buying a home—or already have a mortgage—you’ve probably heard a lot of talk about interest rates.
Think of interest rates as the “price tag” for borrowing money. When you take out a mortgage, you’re not just paying back the amount you borrowed—you’re also paying the lender for the privilege of using their money. That price tag changes based on things like the economy, inflation, and decisions made by central banks.
When rates go up: Your monthly payments can climb, especially if you’re on a variable or tracker mortgage.
When rates go down: You might breathe a sigh of relief, as repayments shrink and affordability improves
Fixed vs. Variable Mortgages
Not all mortgages work the same way:
- Fixed-rate mortgages: Your payments stay the same for the length of the deal. Great for peace of mind, but you might miss out if rates drop.
- Variable or tracker mortgages: These move with the Bank of England’s base rate. That means your payments can rise or fall depending on the economy
If you’re someone who likes a steady plan, fixed-rate might feel more comfortable. If you’re planning to move or refinance in a few years, a variable or tracker rate could save you money early on.
What’s Driving Rates Right Now
Rates aren’t random—they’re shaped by inflation, government policy, and global events. For example, the Bank of England adjusts rates to keep inflation under control. If inflation is high, expect rates to rise. If the economy slows, rates may be cut to encourage spending.
For example, if you have a £200,000 mortgage. A 1% increase in interest rates could add hundreds of pounds to your monthly bill. That’s why even small changes feel like a big deal.
- Higher rates: Can cool down the housing market, making homes less affordable.
- Lower rates: Often encourage more people to buy, pushing demand (and sometimes prices) up
If interest rates fall after you already have a mortgage, you might think about remortgaging to lower your monthly payment or repay your loan faster. However, this isn’t always the right move for everyone, but it’s worth checking when rates drop.
If you’re shopping for a home and rates rise, your buying power may shrink a bit. You might qualify for a slightly smaller loan or have a higher monthly payment.
If you have a variable rate mortgage, rising rates can mean your payment increases when your loan resets. If this makes you nervous, refinancing into a fixed-rate mortgage might be a good option to explore.
