Inflation is one of the most important economic indicators that not only affect people’s purchasing power but also play a key role in the country’s monetary and financial policies. In this article, to examine different methods Calculating inflation We will provide practical tips for predicting inflation next year. If you are looking for better understanding of economic trends and careful financial planning, this article will be useful to you.
The proper understanding of the concept of inflation is the first step to calculate inflation and analyze its effects on the economy. Inflation is called the constant increase in the general level of prices in an economy. In other words, over time and in the event of inflation, the value of the money decreases and the cost of purchasing goods and services increases.
Inflationary factors
Several factors can affect inflation, including:
- Money supply: The rapid increase in money supply without increasing commodities can lead to inflation.
- Total demand: Increasing demand for goods and services, especially during economic prosperity, can raise prices.
- Production Cost: Increasing production costs, such as rising raw material prices or wages, raises the final costs of the goods.
- Government Policies: Financial and monetary policies, such as changes in interest rates or customs tariffs, can directly affect inflation.
Understanding these factors helps us to have more accurate predictors and predictions for calculating inflation.
Inflation calculation methods
There are several ways to calculate inflation, which we will mention here to the most important and practical:
1. Consumer Price Index (CPI)
This index measures changes to a specific basket price changes of consumer goods and services. Inflation calculation based on CPI is performed as a percentage of index change in specified time periods (eg year by year).

2. Producer Price Specific (PPI)
This index measures price changes at the level of production and wholesalers. Although mostly used to analyze production trends, it can also provide clues of inflation at the consumption level.
2. Statistical and econometrics
The use of predictive models such as time series models (such as ARIMA) and econometric regagues help analyze historical data and predict future inflation. These models provide a more accurate picture of the inflation process by combining economic data and effective factors.
Predicting next year’s inflation
Predicting inflation for the coming year requires integration of historical data, analysis of current economic trends, and investigating possible changes in economic policies.
As a result, we need to consider the following:
- Past data analysis: Investigating price indicators changes in previous years and determining the average inflation growth can be a basis for prediction.
- Review of Economic Policy: Any change in monetary and financial policies, such as changing interest rates or economic support policies, can have a direct impact on inflation.
- Supply and Demand Changes: Analyzing the market conditions of commodities, changes in consumer demand and production trends are other important cases in inflation forecast.
- Use Statistical Models: With the help of predictive models, such as the ARIMA model, the inflation process can be modeled with higher accuracy and the possibility of sudden changes can be examined.
By combining these factors, a relative estimate of next year’s inflation rate can be obtained as a guide to economic and financial decisions.
Practical example of inflation calculation
Suppose the consumer price index was 2 units this year and last year. Calculating this year’s inflation is done as follows:
The average inflation rates of previous years or statistical models can be used to predict next year’s inflation. For example, if the average inflation of the past three years was about 1 % and changes in economic policies show relative stability, one might expect to be about 1 to 2.5 % next year. Naturally, for Iran, which has experienced inflation over 2 and 5 percent, it could not expect a 2 or even 2 % tour for the following year.
Online tools and resources for inflation analysis
A) formal databases
- Iran Statistics Center: You can access the latest economic statistics and indicators, including the Consumer Price Index (CPI).
- Central Bank: Information on monetary policies and periodic reports is published in this system, which is very useful for analyzing inflation.
B) Statistical software
- Excel and Google Sheets: These tools allow them to enter historical data, draw charts and calculate the inflation rate automatically.
- Specialized software (such as SPSS, EViews or R): These software are used for deeper analysis and statistical modeling such as ARIMA. Using these tools will help you identify past trends and make more accurate predictions.
A few tips about predicting and calculating inflation
Keep up to date: Keep up to date: To make a more precise prediction, it is important to update economic data regularly. Using monthly or quarter data can provide a more comprehensive image of inflation.
Combination of quantitative and qualitative analysis: In addition to numerical data, consider analyzing economic news, change in government policy, and international events. These factors can play an important role in the sudden change in inflation.
Forecast Models Test: After selecting the appropriate statistical model (eg ARIMA), test it on historical data to ensure its accuracy. If needed, adjust the model parameters to get the best possible results.
Use of Combined Indicators: Instead of relying on one index, incorporate a combination of CPI, PPI and other related indicators into your analysis. This method helps you prevent the influence of the fluctuations of a particular index and have a more comprehensive image of the inflation process.
Why should we know the calculation of inflation to some extent?
You might say what the pain is to calculate inflation? If we were in normal economic conditions, calculating inflation and even knowing its meaning would not have been necessary. However, in Iran, inflation has an inevitable effect on our lives, it is necessary to get acquainted with concepts such as inflation, inflation, and economic risk. We have to get How to invest And the prerequisite for this learning is familiar with these concepts.
