Macro-Economics Formulas

The following are the top 8 macroeconomics formulas –

#1 – Gross Domestic Product

The gross domestic product can be expressed per the expenditure approach and net income approach. As per the expenditure approachExpenditure ApproachThe Expenditure Approach is one of the methods for calculating a country’s Gross Domestic Product (GDP) by adding all of the economy’s spending, including consumer spending on goods and services, investment spending, government spending on infrastructure, and net exports.read more,

the gross domestic product is expressed as the sum of private consumption investments followed by government expenditures and the net exports happening in the nation. On the other hand, the income approach is determined as the sum of labor, interest, rent, and the remaining profits.

Mathematically, two formulas can be expressed as follows: –

Here,

The consumption is represented by C.G represents the government expenditures.I represent an Investment.The net exportsNet ExportsNet exports of any country are measured by calculating the value of goods or services exported by the home country minus the value of the goods or services imported by the home country. It includes various goods and services exported and imported by the government, like machinery, cars, consumer goods.read more are represented by NX.
The labor is represented by W.I represent the Interest.The rent is represented by R.The remaining profits are represented by P.

#2 – Unemployment Rate

The economics can also be assessed as per the unemployment rate in the country. It is normally determined as the ratio of the count of the unemployed labor force to the count in the employed labor force.

Mathematically it can be represented as follows: –

#3 – Money Multiplier Rate

The next metric to understand the situation of the economy is by utilizing the money multiplier metricMoney Multiplier MetricThe money multiplier formula depicts the impact of change in initial deposit on the change in money supply in the economy. It is evaluated as the inverse of the reserve ratio or by dividing the change in money supply by the monetary base fluctuation.read more. It is normally defined as the inverse of the reserve ratio maintained by the bank. Mathematically, it can be represented as follows: –

This metric helps assess how the money deposits can be utilized to enhance the supply of money in the system.

#4 – Real GDP

The real GDP is determined as the ratio of nominal GDPNominal GDPNominal GDP (Gross Domestic Product) is the calculation of annual economic production of the entire country’s population at current market prices of goods and services generated by four main sources: land appreciation, labour wages, capital investment interest, and entrepreneur profits calculated only on finished goods and services.read more and the GDP deflatorGDP DeflatorThe GDP deflator measures the change in the annual domestic production due to changes in price rates in the economy. Hence, it measures the change in nominal GDP and real GDP during a particular year calculated by dividing the nominal GDP with the real GDP and multiplying the resultant with 100.read more. The real GDP is instrumental in the computation and assessment of economic output along with the adjustment for deflationDeflationDeflation is defined as an economic condition whereby the prices of goods and services go down constantly with the inflation rate turning negative. The situation generally emerges from the contraction of the money supply in the economy.read more or inflation. The nominal GDP assesses economic output without the effect of inflation and hence Real GDP is considered a better measurement tool than the Nominal GDP.

The Real GDPReal GDPReal GDP can be described as an inflation-adjusted measure that reflects the value of services and goods produced in a single year by an economy, expressed in the prices of the base year, and is also known as “constant dollar GDP” or “inflation corrected GDP.“read more is expressed as follows: –

#5 – Consumer Price Index

The consumer price indexConsumer Price IndexThe Consumer Price Index (CPI) is a measure of the average price of a basket of regularly used consumer commodities compared to a base year. The CPI for the base year is 100, and this is the benchmark point.read more is determined as the ratio of the cost of products and services for a given year to the cost of products and services for a determined base year. This metric helps in comparing prices for products and services and the changes in the inflation levels. The basket for products and services is to be updated daily, followed by the determination of the cost of the basket and the determination of the Index.

Mathematically, it can be represented or described as follows: –

#6 – Inflation Rate

The inflation rate signals how the prices of services and products have shaped up from year to year. The rate is computed as the difference between the current year CPI level and last year’s CPI level with last year’s CPI level. It is further expressed in percentage terms.

The inflation rate can be expressed as follows: –

Changes in CPI Levels = Levels of CPI for current-year – levels of CPI index last year.

#7 – Real Interest Rate

The real rate of interestReal Interest RateReal interest rates are interest rates calculated after taking inflation into account. It is a means of obtaining inflation-adjusted returns on various deposits, loans, and advances, and thus reflect the real cost of funds to the borrower. read more is determined as the difference in the nominal interest rateNominal Interest RateNominal Interest rate refers to the interest rate without the adjustment of inflation. It is a short term interest rate which is used by the central banks to issue loans.read more and inflation rates. Alternatively, it can be determined using Fischer’s Equation. As per Fischer’s Equation, it is determined as the ratio of nominal interest rates and inflation rates.

Mathematically, it can be expressed as follows: –

As per Fischer’s equation, it can be expressed as follows: –

#8 – Quantity Theory of Money

This relationship can be described as a direct relationship between money and output levels. John Maynard Keynes postulated this relationship.

Mathematically, this relationship would be described or illustrated as follows:

M represents the supply of money.The circulation or speed of the money is expressed as V.The mean level of prices is expressed as P.The transaction volume of services and goods.

Therefore, in Macroeconomics, the following can be summarized as follows: –

Microeconomics Formulas

The following are the top 9 microeconomics formulaMicroeconomics FormulaMicroeconomics is a branch of Economics that evaluates, analyzes, & studies the performance of firms & individuals towards delivering sustainable results through employing scarce resources. Also, it examines the interaction between these firms & individuals. read more –

As per the microeconomics, the help of the following formula in understanding the position of the economy is as follows: –

#1 – Total Revenue

It is defined as the situation wherein demand is assessed in terms of price elasticity. It is expressed as the product of the overall price and the quantity in demandQuantity In DemandQuantity demanded is the quantity of a particular commodity at a particular price. It changes with change in price and does not rely on market equilibrium.read more. If the prices are high, it will result in inelastic demand on prices wherein higher prices result in more revenues. Demand is elastic when the prices are high and results in low volumes.

Mathematically, it can be illustrated as follows: –

#2 – Marginal Revenue: –

The marginal revenueMarginal RevenueThe marginal revenue formula computes the change in total revenue with more goods and units sold.” The value denotes the marginal revenue gained. Marginal revenue = Change in total revenue/Change in quantity sold. read more is expressed as the ratio of total revenue changes with respect to the modifications in the quantity retailed. Marginal revenue is the additional revenue earned for the additional quantity sold. Mathematically, it can be illustrated as follows: –

#3 – Average Revenue

Revenues can be described as the receipts a firm received once it sold finished goods to its consumers. The average revenue is the total revenue ratio concerning the overall quantity sold. Mathematically, it can be illustrated as follows: –

#4 – Total Cost

Under economics, the total cost is determined as the sum of fixed and variable costs. Fixed costs are the type of costs that endure being the same throughout the levels of quantity sold by the business. The variable costs are the costs that tend to vary with the level of goods sold by the organization.

#5 – Marginal Cost

This is defined as the appreciation or deterioration in the overall costs that the business incurs while it prepares finished goods ready for the sale. Graphically, marginal costsMarginal CostsMarginal cost formula helps in calculating the value of increase or decrease of the total production cost of the company during the period under consideration if there is a change in output by one extra unit. It is calculated by dividing the change in the costs by the change in quantity.read more are plotted as a U-shaped curve wherein the costs appreciate initially and as the production rises, the costs deteriorate.

#6 – Average Total Cost

The average total cost is the total costs incurred by the business involved in manufacturing and production to the number of items produced by the business. In such a relationship, determine the total costs and total quantity to arrive at the average total costs. Mathematically, it can be illustrated as follows: –

#7 – Average Fixed Costs

The average fixed costAverage Fixed CostAverage Fixed Cost refers to the company’s fixed production expenses per unit of goods produced. Fixed costs are costs that do not vary with the amount of output produced by the company and are independent of the number of goods or services produced by the business.read more

is the total fixed costs incurred by the business involved in manufacturing and production to the number of items produced by the business. In such a relationship, determine the total fixed costs and total quantity to arrive at the average total fixed costs.

Mathematically, it can be illustrated as follows –

#8 – Average Variable Costs

The average variable costAverage Variable CostAverage Variable Cost refers to the cost that directly varies with the output incurred on each unit of goods or services. It is evaluated by dividing the total variable cost incurred during the period by the number of units produced.read more is defined as the total variable costs incurred by the business involved in manufacturing and production to the number of items produced by the business. In such a relationship, determine the total variable costs and total quantity to arrive at the average total variable costs. Mathematically, it can be illustrated as follows: –

#9 – Profit Made by the Firm

In microeconomics, profit could be computed using several relationships. Firstly, it can be computed as the difference between total revenues and costs. It can be computed as the difference between marginal revenue and marginal costs. Whenever the profits are lesser than average variable costs, the business can no longer sustain itself, and it has to be shut down. Mathematically, it can be illustrated as follows: –

It can additionally be illustrated as follows: –

When marginal revenue exceeds marginal costs, the organization or firm should produce more items to enhance its profitability. Similarly, the organization or firm should produce fewer items to lower costs when marginal revenue deteriorates below marginal costs.

Therefore, in Microeconomics, the following can be summarized as follows: –

Relevance and Use of Economics Formula

The world bank monitors the nation’s overall financial progress utilizing economic indicators determined by them on periodic intervals. Such reports are made available to the general public utilizing government publications. The nation can be doing well economically if it presents fairly stable economic indicators. Therefore, these economic indicatorsEconomic IndicatorsSome economic indicators are GDP, Exchange Rate Stability, Risk Premiums, Crude Oil Prices etc. read more are broadly recognized as the measure of economic formula.

The popular economic formulas are based on the fact of how the economy is being The popular economic formulas are based on how the economy is being analyzed. For example, suppose the analysis is done on the microeconomic level. In that case, the economic formula is determined as the difference between total revenues generated by the business and the cost incurredCost IncurredIncurred Cost refers to an expense that a Company needs to pay in exchange for the usage of a service, product, or asset. This might include direct, indirect, production, operating, & distribution charges incurred for business operations. read more to generate the revenue. However, when an analysis is performed at the macroeconomic level, the economic formula is derived by employing the gross domestic product.

An economy always displays how the well human being has utilized the available resources to derive the maximum value addition. Therefore, economics is more related to social science and broadly focuses on spending, consumption, investment, and overall trade achieved in a given financial period.
