Richard Witt's book Arithmeticall Questions, published in 1613, was a landmark in the history of compound interest. It was wholly devoted to the subject (previously called anatocism), whereas previous writers had usually treated compound interest briefly in just one chapter in a mathematical textbook. Witt's book gave tables based on 10% (the ...
Compound interest is the interest earned on that higher balance. Often described as earning interest on your interest, compounding is done on a schedule — such as daily, monthly or annually.
These rules apply to exponential growth and are therefore used for compound interest as opposed to simple interest calculations. They can also be used for decay to obtain a halving time. The choice of number is mostly a matter of preference: 69 is more accurate for continuous compounding, while 72 works well in common interest situations and is ...
Over the 30-year period, compound interest did all the work for you. That initial $100,000 deposit nearly doubled. Depending on how frequently your money was compounding, your account balance grew ...

The 49 cents is compounded interest earned from the first to second year, as it is interest earned on top of the initial $7 in interest earned after the first year. The $7 gained in year one is ...
This is a reasonable approximation if the compounding is daily. Also, a nominal interest rate and its corresponding APY are very nearly equal when they are small. For example (fixing some large N), a nominal interest rate of 100% would have an APY of approximately 171%, whereas 5% corresponds to 5.12%, and 1% corresponds to 1.005%.
