How to Calculate your Personal Inflation Rate

Open the finance section of any newspaper or tune into the evening news, and the word inflation is inescapable. In the past year, we have seen fuel prices go up, electricity bills rising as well as an increase in the price of produce and other food items. 

While we sit and lament about how the economy is suffering, it is also important to assess how this affects you. Inflation does not affect every individual in the same way, it all depends on your spending habits. And this is why it is important to know what your personal inflation rate is.

What is a personal inflation rate?

Your personal inflation rate measures the change in prices based on your personal expenses, as opposed to the national average. It gives you a clear picture of how much more you are spending every year.

Your personal inflation rate is not the same as what is reported in the news for a variety of reasons:

If you choose to spend on more expensive brands and products, then your personal inflation rate will be higher than the national average.

Conversely, if you spend on less expensive brands and products, then your personal inflation rate will be less than the national average. SImple, right?

How can I calculate my inflation rate?

Track your spending. You can use apps like You Need a Budget or Africa’s Pocket’s budgeting tool or you can simply do this on a spreadsheet.

The easiest way to do this is total up your expenses for the year and compare them to last year’s expenses:

(2022 expenses - 2021 expenses) / 2021 expenses  * 100

For example:

- 2022 expenses = KES 2,000,000

- 2021 expenses = KES 1,650,000

- Do the math = (2,000,000-1,650,000)/1,650,000 *100

Personal inflation rate = 21.21%

This is the most basic way to calculate this. However, oftentimes we make unique large expenses one particular year that we are not likely to make the next year, such as buying a car.

There are two ways to manage this:

  1. Do not include such expenses in your calculation. 
  2. Spread out this expense over a course of time. In the car example, if you expect to use your car for the next 10 years, then add 10% of the cost to your expenses every year. So for instance, if the car cost you KES 500K, then put in KES 50K as a line item in your expenses for the next ten years.

You can choose which option you prefer.
