Compound interest is contrasted with simple interest, where previously accumulated interest is not added to the principal amount of the current period. Compounded interest depends on the simple interest rate applied and the frequency at which the interest is compounded.

Index (statistics) In statistics and research design, an index is a composite statistic – a measure of changes in a representative group of individual data points, or in other words, a compound measure that aggregates multiple indicators. [1] [2] Indexes – also known as composite indicators – summarize and rank specific observations.

[1] An example of a composite measure is an IQ test, which gives a single score based on a series of responses to various questions. Three common composite measures include: typologies ...
The wheat and chessboard problem (sometimes expressed in terms of rice grains) is a mathematical problem expressed in textual form as: If a chessboard were to have wheat placed upon each square such that one grain were placed on the first square, two on the second, four on the third, and so on (doubling the number of grains on each subsequent ...
Compound interest at a constant interest rate provides exponential growth of the capital. See also rule of 72. Pyramid schemes or Ponzi schemes also show this type of growth resulting in high profits for a few initial investors and losses among great numbers of investors. Computer science.

The nominal interest rate, also known as an annual percentage rate or APR, is the periodic interest rate multiplied by the number of periods per year. For example, a nominal annual interest rate of 12% based on monthly compounding means a 1% interest rate per month (compounded). [2] A nominal interest rate for compounding periods less than a ...
Not all interest rates work the same. Your choice among these two main types come down to how you save and how you borrow. Here's what to know about fixed and variable rates.
