It is the ratio of the percentage change in operating income to the percentage change in units sold.<\/p>\n\n\n\n<p>The relationship can be expressed by the following equation:<\/p>\n\n\n\n<p>$$ \\text{DOL}=\\cfrac {\\text{Percentage change in operating income}}{\\text{Percentage change in units sold}} $$<\/p>\n\n\n\n<p>Operating income is, however, equal to the difference between revenue and total operating costs (variable and fixed costs). Taking into account the fact that fixed costs do not change, operating income will, therefore, change based on the contribution margin i.e. the product of the quantity sold and the difference between the price per unit and the variable cost per unit.<\/p>\n\n\n\n<p>This simplifies the equation to:<\/p>\n\n\n\n<p>$$ \\text{DOL}=\\cfrac {Q(P-V)}{Q(P-V)-F} $$<\/p>\n\n\n\n<p>Where:<\/p>\n\n\n\n<p>Q = the number of units;<\/p>\n\n\n\n<p>P = the price per unit;<\/p>\n\n\n\n<p>V = the variable operating cost per unit;<\/p>\n\n\n\n<p>F = the fixed operating cost;<\/p>\n\n\n\n<p>P &#8211;
