Augmenter vs. accroître vs. s'accroître vs. croître
The French language offers an array of choices for expressing the idea of increase, each with its own nuance. Augmenter, accroître, 's'accroître', and croître are such options that can sometimes be confusing due to their similarities. Understanding the differences can greatly improve the precision in communication.
Augmenter
A2Augmenter is a commonly used transitive or intransitive verb meaning to increase in size, quantity, or intensity.

(The company's expenses have increased.)

(The company seeks to increase its turnover.)
S'accroître
B2'S'accroître' is the pronominal form of accroître, meaning to grow or to rise, often used in a general or economic context. It emphasizes the action as happening by itself, without specifying an agent.
La population mondiale continue de s'accroître rapidement.
(The world's population continues to grow rapidly.)

(The company's profits have increased over the last quarter.)
Croître
B1Croître carries the idea of natural growth and is often used in reference to living organisms or things having a life-like development pattern. It's less commonly used than augmenter. Croître is an intransitive verb only.

(Plants grow faster in spring.)

Summary
While augmenter, accroître, 's'accroître', and croître all convey the notion of increase, they differ in usage, context, and nuance. Augmenter is versatile and common, appropriate for many everyday contexts involving increases; accroître carries a more formal tone, often related to abstract or numerical growth; 's'accroître' emphasizes self-driven growth typically seen in populations or economies; while croître denotes natural or inherent growth, frequently related to living beings or personal attributes such as interest or knowledge. Understanding these subtleties can greatly enhance one's expressing capabilities in French.
