Big-O Operation Count Calculator

Compare operation counts across common Big-O complexity classes for a given input size, from constant time up to factorial time

Frequently Asked Questions

What does Big-O notation describe?

Big-O describes how the amount of work an algorithm does grows as the input size increases. This tool shows the raw operation count for each complexity class so you can compare how they scale for a given input size.

Why do exponential and factorial counts show as overflow?

Exponential and factorial growth explode so quickly that the counts exceed the range a standard double-precision number can hold. The tool labels these as overflow to show that the algorithm is intractable at that input size.
