Exponential growth and decay can be determined with the following equation: N = (NI)(e^kt). In this equation, "N" refers to the final population, "NI" is the starting population, "t" is the time over which the growth or decay took place and the "k" represents the growth or decay constant. If necessa

An element's radioactive decay can be determined through a single equation which requires imputing the isotope's half life, its rate of decay and the decay time since the rate of decay is measured.

To calculate percent sales growth over a period, subtract the previous sales figure from the current sales figure, divide the result by the previous sales figure, and then multiply this number by 100, explains Michael Marz for the Houston Chronicle. In order to obtain the most accurate growth percen

Subtracting a past population value from the present population value, and dividing this result by the past population value, yields the population-growth rate. Multiplying the population-growth rate by 100 yields the growth percentage.

Calculate population growth rate by dividing the change in population by the initial population, multiplying it by 100, and then dividing it by the number of years over which that change took place. The number is expressed as a percentage.

According to Investopedia, to calculate an annual growth rate, take the ending value and divide it by the beginning value. Place that amount to the power of one over the number of years of growth, and subtract one from that amount. This averages growth over a period of years.

The basic equation for calculating population growth multiplies the population size by the per capita growth rate, which is calculated by subtracting the per capita death rate from the per capita birth rate. This simplistic calculation does not factor in the effects of migration or immigration on a

The internal growth rate of a firm is calculated by subtracting its rate of earnings retention from its return on assets, according to Boundless. A company's return on assets is derived from dividing its net income by its total number of assets. Growth is not always favorable.
