The first method is to add up every dollar of spending, that is can only count final goods when the final buyer buys them. An example would be if a bag was made in November 2020, but did not get sold until February 2021. It would only count for 2021's GDP because that is when the final buyer purchased it. This method does not count when items are produced.

The second method is adding up every dollar value of output produced. This amount increases as the product go through each stage of production. Sticking with the bag example, add up the cost of material and cost producing it, then subtract the retail value we want to sell it for. This tells us the profit we made on this item.

The final method is adding up every dollar value of income earned. This is total wages and total profits. This only focuses only on the worker's wages, and the profits the bosses and business owners earn

Economic growth is usually determined by how much the production function is producing in terms of GDP per person. Like any function, this production function takes inputs: labor--human capital, and physical capital-- and translates those into production in the form of GDP. Technological progress shifts the production upward because the new progress allows for more products to be made with the same amount of inputs.
