At every compounding date the balance is multiplied by the periodic rate. With a nominal annual rate the periodic rate is the annual rate divided by the number of periods in a year; with an effective annual rate it is de-compounded, so that a full year of compounding reproduces exactly the rate you entered.
Compounding more often raises the effective annual rate, but the effect is smaller than people expect. At 7% nominal, moving from yearly to monthly compounding lifts the effective rate to about 7.23%; moving on to daily adds only a few more hundredths of a percent. Compoundly shows the effective figure under the chart so the difference is never overstated.
