The following article will guide you to know why cost curve is “U” shaped. The addition of fixed and Variable Cost gives us total costs, which when divided by the output give us Average Costs in the short period.

It is generally believed by economists that the long-run average cost curve is normally U shaped, that is, the long-run average cost curve first declines as output is increased and then beyond a certain point it rises.

Because the short run marginal cost curve is sloped like this, mathematically the average cost curve will be U shaped. Initially, average costs fall. But, when marginal cost is above the average cost, then average cost starts to rise. Marginal cost always passes through the lowest point of the average cost curve.
ATC (Average Total Cost) = Total Cost / quantityAVC (Average Variable Cost) = Variable cost / QuantityAFC (Average Fixed Cost) = Fixed cost / QuantityThe long-run cost curves are u shaped for different reasons. It is due to economies of scale and diseconomies of scale. If a firm has high fixed costs, increasing output will lead to lower average costs. However, after a certain output, a firm may experience diseconomies of scale. This occurs where increased output leads to higher average costs. Fo...

The long-run average cost curve shows the cost of producing each quantity in the long run, when the firm can choose its level of fixed costs and thus choose which short-run average costs it desires. If the firm plans to produce in the long run at an output of Q 3 , it should make the set of investments that will lead it to locate on SRAC 3 ...
Shapes of Long-Run Average Cost Curves. While in the short run firms are limited to operating on a single average cost curve (corresponding to the level of fixed costs they have chosen), in the long run when all costs are variable, they can choose to operate on any average cost curve.

The long-run cost function is crucial for strategic planning and long-term decision-making, as it provides insight into the optimal scale of production and how costs behave when the firm has the complete freedom to adjust all inputs.
