The answer to this question depends on several things, the most important of which is the fitness evaluation. I'm going to ignore evaluation- you must determine this for yourself based on your application.
Some of the things the effect the time complexity are:the data structures used to represent the individuals and the population, the genetic operators used, and the implementation of the genetic operators. Roulette wheel selection, for example, can be anywhere from O(n^2) when done naively, to O(log(n)), or even O(n) using something like Vose Alias Algorithm.
The simplest case- roulette wheel selection, point mutation, and one point crossover with both individuals and populations represented by fixed length vectors- has time complexity O(gens * (mut + cross + select)) where gens is the number of generations, mut is the complexity of point mutation (n*m with n the size of the population and m the size of the individuals), cross the time complexity of crossover (n*m again), and select the time complexity of selection (n in the case of an efficiently done roulette wheel).
Therefore, the time complexity of a simple Genetic Algorithm is O(gens*n*m) as this is the dominating term.
I'm sure a much better explanation can be found in the literature.

What is time complexity of an algorithm?
Time complexity is a function which value depend on the input and algorithm of a program and give us idea about how long it would take to execute the program
Why time complexity is better than actual running time?
Finding a time complexity for an algorithm is better than measuring the actual running time for a few reasons: # Time complexity is unaffected by outside factors; running time is determined as much by other running processes as by algorithm efficiency. # Time complexity describes how an algorithm will scale; running time can only describe how one particular set of inputs will cause the algorithm to perform. Note that there are downsides to time complexity measurements: # Users/clients do not care about how efficient your algorithm is, only how fast it seems to run. # Time complexity is ambiguous; two different O(n2) sort algorithms can have vastly different run times for the same data. # Time complexity ignores any constant-time parts of an algorithm. A O(n) algorithm could, in theory, have a constant ten second section, which isn't normally shown in big-o notation.
Time complexity of backtraCking algorithm?
O 2^(n)
How is time complexity of an algorithm calculated?
The usual definition of an algorithm's time complexity is called Big O Notation. If an algorithm has a value of O(1), it is a fixed time algorithm, the best possible type of algorithm for speed. As you approach O(∞) (a.k.a. infinite loop), the algorithm takes progressively longer to complete (an algorithm of O(∞) would never complete).
What are the two crucial factors that are used to evaluate the behavior of any implemented algorithm?
Time complexity and space complexity. More specifically, how well an algorithm will scale when given larger inputs.
What is time complexity and space complexity?
"Running Time" is essentially a synonym of "Time Complexity", although the latter is the more technical term. "Running Time" is confusing, since it sounds like it could mean "the time something takes to run", whereas Time Complexity unambiguously refers to the relationship between the time and the size of the input.
What is the time complexity of infix to post fix conversion algorithm?
