“Compound interest is the eighth wonder of the world,” is a quote commonly attributed to Albert Einstein. Ultimately, it’s unknown whether the famous physicist truly ever uttered those words.
Let be the purchasing power of a dollar at time t (the number of bundles of consumption that can be purchased for $1). Then π t = 1 / ( P L t ) {\displaystyle \pi _{t}=1/(PL_{t})} , where PL t is the price level at t (the dollar price of a bundle of consumption goods).
As the number of compounding periods tends to infinity in continuous compounding, the continuous compound interest rate is referred to as the force of interest . For any continuously differentiable accumulation function a(t), the force of interest, or more generally the logarithmic or continuously compounded return , is a function of time as ...
For continuous compounding, 69 gives accurate results for any rate, since ln(2) is about 69.3%; see derivation below. Since daily compounding is close enough to continuous compounding, for most purposes 69, 69.3 or 70 are better than 72 for daily compounding. For lower annual rates than those above, 69.3 would also be more accurate than 72. [3]

For example, if someone purchases 100 shares at a starting price of 10, the starting value is 100 x 10 = 1,000. If the shareholder then collects 0.50 per share in cash dividends, and the ending share price is 9.80, then at the end the shareholder has 100 x 0.50 = 50 in cash, plus 100 x 9.80 = 980 in shares, totalling a final value of 1,030.
