What Are Interest Rates and Why Are They So Important?
While interest rates might seem confusing at first glance, they’re actually fairly simple. Essentially, they refer to the cost of borrowing money or the reward for saving it.
For example, imagine you’ve got your eye on a new mountain bike but don’t have enough money to afford it. You could always borrow the extra money from your local bank.
However, you can’t borrow from your bank for free. In return for borrowing, you'd not only be expected to pay back what you owe in the near future, but also an extra charge which we call “interest”. Pretty straightforward so far, right?
However, interest also works in another way too. For example, interest can actually benefit you when you start to deposit money into your own bank account. Over time, whatever you’ve entered will slowly grow as the bank pays you said interest.
Why do banks pay interest? Well, they typically use the money their customers deposit for various investments and loans to other customers. In their own way of saying thank you, they pay you for allowing them to use your hard earned cash.
Who Controls the Interest Rates?
But who decides how much interest rates are? Well, in the UK, the Bank of England is in charge of setting the base interest rate, which influences all other interest rates in the economy - including those for loans, mortgages and saving accounts.
The decisions about the base rate are made by a group within the Bank of England called the Monetary Policy Committee (MPC) who meet regularly to review the economic situation of the country and decide whether to raise, lower, or maintain the base rate.

Factors Influencing Interest Rates
There are many different factors influence how high or low interest rates are, including:
- Inflation: When inflation is super high, the Bank of England may make the decision to raise interest rates to help control the rising prices of both goods and services. Higher rates make borrowing more expensive and saving more rewarding, helping to slow down inflation.
- Economic Growth: If the economy is growing too rapidly, the bank may also raise rates to prevent it from overheating, which can lead to unsustainable levels of spending and investment. Similarly, if the economy is slowing down, lower rates can help stimulate growth by making things like borrowing cheaper.
- Employment Levels: Lastly, higher employment usually leads to higher spending, which can drive up inflation. In such cases, the Bank may raise interest rates. Lower employment might lead to lower rates to encourage economic activity.
How Do You Calculate Interest on Savings?
So is it possible to calculate what sort of interest you would get on your savings? Yes, if you use this straightforward formula.
Interest = Principal × Rate × Time
Let’s break down these terms together:
Principal: the initial amount of money that you have saved or invested.
Rate: The annual interest rate, expressed as a decimal. For example, 3% becomes 00.3.
Time: Basically how long the money has been invested or saved.
£1,000× 0.03 ×1 = £30
So, as you can see above, if you had £1000 in your account, your savings would have grown by £30, making the total amount £1030.
How Do Changes in Interest Rates Affect Producers of Goods?
Interest rates don’t just affect consumers, they also have a pretty sizable impact on businesses too. How? Well we know that high interest rates make borrowing money more expensive, right? As a result, companies may make the decision to delay or reduce their investments in new projects, equipment, or any plans to expand.

Additionally, higher borrowing costs can also steeply drive up the price of production, which are commonly passed on to everyday consumers through increased prices.
On the other hand, low interest rates may mean companies decide to invest more in their operations instead, leading to an increased rate of production, more hiring, and potentially much lower prices for customers.
What Are the Main Sources of UK Government Revenue?
In order to get a better picture of how the national economy works, understanding the main sources of government revenue and spending is pretty important too.
The main way the UK government generates its revenue is through taxation, of which there are primarily two main types - direct taxes and indirect taxes. But what’s the difference between the two?
The first of these, direct taxes, are generally levied on the wealth of individuals and corporations. For example, two of the main types include income tax (charged on earnings) and corporation tax (on company profits). Additionally, insurance contributions are also a form of direct tax too.

Direct taxes are considered progressive because they take a larger percentage of income from higher earners, thereby reducing income inequality.
On the other hand, indirect taxes are applied to goods and services, meaning they ultimately affect consumers like you and me. Ever heard of VAT? That stands for Value Added Tax, which is included in the price of most products and services. Therefore every time you buy something, a portion of what you pay is this tax.
These types of taxes tend to be regressive, as they take up a larger portion of the income of lower earners and make everyday goods and services that much more expensive for them.
What Are the Main Sources of UK Government Spending?
Government spending in the UK is another key element of the national economy. The government allocates funds to various sectors to make sure they’re running properly.
- Healthcare: The National Health Service (NHS) receives significant funding to provide healthcare services to the public
- Education: Government funds are directed towards schools, colleges, and universities to ensure quality education for all.
- Public Services: Funding for police, fire services, and other essential public services the general public rely on.
Conclusion
In conclusion, the UK economy is deeply influenced by interest rates, which are set by the Bank of England. These rates play a crucial role in determining whether individuals and businesses decide to save or borrow money. Additionally, government revenue, which is usually collected through direct and indirect taxes, goes a long way in funding critical public services like healthcare, education, and safety.
