About Discount Break-Even Volume
Offering a discount shrinks per-unit profit, so the calculator finds how many extra units must sell to hold gross profit at its pre-sale level. Most promotions never lift volume enough to pay for the price cut, and knowing the break-even volume exposes promotions that only give money away.
Formula
Discount Break-Even Volume
Break-even volume = current profit / (discounted price - cost)
