Meaning
The kanji 利 (ri) is a versatile character that encompasses the concepts of benefit, profit, advantage, and effectiveness. At its core, it signifies gaining something positive or being in a favorable position. It often appears in contexts related to finance, such as interest on money (利子), or in discussions of personal or corporate gain (利益). Beyond mere financial gain, it also extends to general advantage (利点) and convenience (便利).
The character is composed of two radicals: 禾 (nogi-hen), representing grain or harvest, and 刀 (katana), representing a knife or sword. The ancient form of 利 depicted a knife cutting grain, symbolizing the act of harvesting or reaping. This visual metaphor effectively illustrates the idea of extracting value or gaining something useful from a situation or resource. Just as a farmer reaps the harvest, one gains a 'benefit' or 'profit' from an endeavor. This connection between cutting grain and a positive outcome forms the etymological basis for the kanji's diverse meanings. This kanji has 7 strokes and is taught in Grade 4 of elementary school, making it a Jōyō kanji.

Memory Tip
Visualize a field of abundant 禾 (grain) ready for harvest. A farmer arrives with a sharp 刀 (knife) and efficiently cuts down the stalks. This act directly results in a great harvest, signifying 'profit' and 'benefit'. Thus, the 'knife' cuts the 'grain' to yield a 'profit' or 'advantage'. The more efficiently the knife works, the greater the benefit! This vivid story should help you recall that 利 is all about gaining something positive.
