The effective annual rate is the total accumulated interest that would be payable up to the end of one year, divided by the principal sum. When you buy stocks in a brokerage account and they gain value over time, you’re not getting compound interest. Rather, you’re getting the option to take advantage of compounded returns, since stocks don’t pay interest like bonds and savings accounts do.

Zero-coupon-bond issuers use the power of compounding to increase the value of the bond so it reaches its full price at maturity. The same logic applies to opening an individual retirement account (IRA) and taking advantage of an employer-sponsored retirement account, such as a 401(k) or 403(b) plan. Start early and be consistent with your payments to get the maximum power of compounding. Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one.

For example, monthly capitalization with interest expressed as an annual rate means that the compounding frequency is 12, with time periods measured in months. Compound interest is contrasted with simple interest, where previously accumulated interest is not added to the principal amount of the current period, so there is no compounding. The simple annual interest rate is the interest amount per period, multiplied by the number of periods per year.

It saddens me to see such disregard for the future. Everyday, we have people who live in a mindset of scarcity instead of abundance. People who are destroyers instead of creators.

Similarly, replacing the “R” in R/200 on the third line with 2.02 gives 70 on the numerator, showing the rule of 70 is most accurate for periodically compounded interests around 2%. For higher rates, a larger numerator would be better (e.g., for 20%, using 76 to get 3.8 years would be only about 0.002 off, where using 72 to get 3.6 would be about 0.2 off).

If you are the participant lending out the money, you receive the interest. If you deposit money in your bank account, it is similar to “lending” money to the bank and therefore you receive interest on the amount you deposit. First, the yield, which is calculated as the dividend payout divided by the market valuation of the company.

Since the principal P is simply a coefficient, it is often dropped for simplicity, and the resulting accumulation function is used instead. The accumulation function shows what $1 grows to after any length of time. For continuous compounding, 69 gives accurate results for any rate, since ln(2) is about 69.3%; see derivation below.
