# Relationship between total cost marginal and average variable

### Marginal cost and average total cost (video) | Khan Academy

Average variable costs are found by dividing total fixed variable costs by output. It is important to note that marginal cost is derived solely from variable costs, and not fixed costs. The general rules governing the relationship are: Marginal . Marginal Cost (MC) & Average Total Cost (ATC). Total cost is variable cost and fixed cost combined. TC=VC+FC. Now divide total cost by quantity of output to get . The total cost, in this reference, is the sum total of the total fixed cost plus total The marginal cost curve bears relationship to the average cost curve. If the marginal cost first falls and then rises, it will be equal to the average variable cost at.
