National Income Calculator

Our National Income Calculator helps you find a country's total factor income. We developed this tool so you can work out national income with ease. Choose a method, enter the needed values, and click Calculate. The tool supports the GDP, income, spending, and production methods. It can also show domestic income and income per person when you enter a population value.

National Income Formula

The main formula is:

National Income = GDP at Market Price + NFIA − Depreciation − Indirect Taxes + Subsidies

GDP at Market Price is the value of final goods and services made within a country. NFIA is factor income earned by residents abroad minus factor income earned by foreign residents in that country.

Depreciation is the loss in value of fixed assets over time. Indirect taxes are taxes on goods and services. Subsidies are funds paid by the state to support goods or services.

First, find net indirect taxes:

Net Indirect Taxes = Indirect Taxes − Subsidies

Then find gross national product:

GNP at Market Price = GDP at Market Price + NFIA

Next, find net national product:

NNP at Market Price = GNP at Market Price − Depreciation

At last:

National Income = NNP at Market Price − Indirect Taxes + Subsidies

In the traditional macroeconomics model, this result is called NNP at Factor Cost. It shows net factor income earned by a nation's residents. Market price includes net taxes on goods and services. Factor cost removes those net taxes.

GDP tracks output within a country. GNP, also called GNI in modern accounts, adds net factor income from abroad. NDP is GDP minus depreciation. NNP is GNP minus depreciation. NNI is the net national income measure used in modern accounts. These terms are linked, but their use can vary by accounting system.

How to Use Our Online National Income Calculator

1. Choose a method. Select GDP, Income, Expenditure, or Production. The GDP method is the default choice.

2. Enter the main values. For the GDP method, add GDP at market price. You can also enter depreciation, indirect taxes, and subsidies.

3. Add NFIA. Enter net factor income from abroad. Or choose the parts option and enter income received from abroad and income paid abroad.

4. Set the units and currency. Choose a unit, such as billion or million. You can also choose a currency sign. Add population if you want income per person.

5. Click Calculate. The tool checks your entries and shows the result if they pass. The GDP and Expenditure methods also show GNP and NNP at market price. The tool can show domestic income and income per person when you enter population.

For the Income method, enter employee pay, operating surplus, and mixed income. For the Expenditure method, enter consumption, investment, state spending, exports, and imports. For the Production method, enter output and intermediate use. The tool applies the matching formula for each method.

Example of National Income Calculation

Suppose a country has these values. GDP is $1,000 billion. NFIA is $50 billion. Depreciation is $100 billion. Indirect taxes are $80 billion. Subsidies are $30 billion.

First, find GNP:

GNP = 1,000 + 50 = $1,050 billion

This adds income from abroad to local output.

Next, find NNP at Market Price:

NNP at Market Price = 1,050 − 100 = $950 billion

This step takes away the loss in value of fixed assets.

Now find national income:

National Income = 950 − 80 + 30 = $900 billion

The result is $900 billion. Think of it as a total pool of net income earned by the nation's factors of production. The tax and subsidy step turns the market price value into a factor cost value.

Frequently Asked Questions

What is a National Income Calculator?

It is an online tool that works out a country's national income from key economic data. This tool has four methods.

How do you calculate national income?

Use GDP plus NFIA, then subtract depreciation and net indirect taxes. You can also use the income, spending, or production method.

What is the formula for national income?

National Income = GDP at Market Price + NFIA − Depreciation − Indirect Taxes + Subsidies.

What is NNP at factor cost?

It is net national product after net indirect taxes are removed. In the traditional model, it equals national income.

What is the difference between GDP and GNP?

GDP counts output made within a country. GNP adds net factor income from abroad.

What is Net Factor Income from Abroad?

NFIA is income residents earn from work and assets abroad, minus income foreign residents earn in the home country.

What are the three methods of calculating national income?

The three methods are the income method, expenditure method, and production method. The production method is also called the value added method.

How does depreciation affect national income?

Depreciation lowers national income. It accounts for the wear and loss of value of fixed assets.

What is the difference between factor cost and market price?

Market price includes net taxes on goods and services. Factor cost removes indirect taxes and adds subsidies.

Can I calculate national income online for free?

Yes. You can use this National Income Calculator online. Enter your values and run the calculation.
