About Inflation and Buying Power

What is Buying Power?

Buying power, or purchasing power, refers to the amount of goods or services that can be purchased with a unit of currency. As inflation increases, the same amount of money buys fewer goods and services over time.

1970-1979: Average 7.1% annually
1980-1989: Average 5.6% annually
1990-1999: Average 2.9% annually

Tips for Maintaining Buying Power

Invest in assets that historically outpace inflation (e.g., stocks, real estate)
Consider inflation-protected securities like TIPS
Review and adjust your budget regularly to account for rising costs
Negotiate salary increases that at least match the rate of inflation
Be strategic about major purchases, especially during high-inflation periods

What Is the Buying Power Calculator?

The Buying Power Calculator is a handy tool that helps you understand how inflation affects your money over time. It shows how much you need in the future to buy the same amount of goods and services you can today. This can help you plan your finances better and make informed decisions about your spending and savings.

Why Does Purchasing Power Matter?

Your purchasing power is important because it determines how far your money will go. If prices rise due to inflation, the same amount of money will buy you less. Knowing how inflation affects your buying power helps you:

Budget for future expenses more accurately.
Make smarter Financial decisions.
Set realistic savings goals based on future prices.

How to Use the Buying Power Calculator

Using the Buying Power Calculator is straightforward. You start by entering an initial amount of money and the years you want to examine. You also need to input an average annual inflation rate. Once you have all the information, the calculator estimates how much you would need in the future to maintain your current purchasing power.

Inputting Your Data

When using the calculator, you’ll fill in several fields. It's essential to provide accurate information for the best results. You'll need to enter:

Your initial amount of money (e.g., £1,000).
The start and end years for your calculation.
The expected average annual inflation rate, which can vary.

Understanding Your Results

Once you input your data, the calculator generates results that show the future value needed to keep the same buying power. It will also reveal how much purchasing power you've lost due to inflation and the total percentage change over time. This information helps you grasp the impact of inflation on your finances.

Comparing Everyday Costs

The Buying Power Calculator allows you to compare the future costs of common items like groceries and gas. You can add multiple items, such as:

A gallon of petrol.
A movie ticket.
A loaf of bread.

This feature gives you a clearer picture of how inflation may affect your daily expenses.

Visualising Inflation's Impact

The calculator also includes visualisation tools that illustrate how your buying power changes over time. Charts and graphs can help you see trends in inflation and how it might affect your future spending. This visual aspect makes it easier to grasp complex financial concepts.

Keeping Track of Inflation

Staying informed about inflation rates can greatly benefit your financial planning. The calculator provides data on historical inflation rates and tips to maintain your purchasing power. By understanding these rates, you can make better decisions about investments or savings to protect your finances against inflation.
