Amount means the total quantity or extent of something. Rate means the measure or quantity of something in relation to another quantity or measure.

Key Differences

Amount refers to the total quantity or sum of something, without considering time or rate. Rate, however, measures the frequency or speed of something over a period of time.
When discussing finances, amount could mean the total sum of money, while rate often refers to interest rates or charges per unit time.
Amount is often used to quantify things in bulk or as a whole, such as the amount of water in a tank. Rate usually involves a ratio or comparison, like speed (miles per hour).
In recipes, amount can refer to the quantity of ingredients, whereas rate could be used to describe the rate of pouring or mixing.
Amount can pertain to non-quantifiable aspects, such as the amount of effort. Rate tends to be more quantifiable, like the rate of success.
