Overview
The High-Low Method is a fascinating albeit simplistic tool used in accounting to predict how costs change along with varying levels of activity. It’s akin to using a ruler to measure the waves of the ocean—somewhat useful, but you might miss out on predicting a tsunami.
What It Is
Imagine plotting a year’s worth of your caffeine expenditures against your productivity levels at work. By connecting your cheapest (least productive) and most expensive (most productive) coffee days, you form a straight line of ‘caffeine cost behavior.’ This is, in a nutshell, what the high-low method does with business costs. It plots costs at the highest and lowest points of activity, draws a straight path through these extremities, and voila!—you have a model to interpret how costs behave as activity levels fluctuate.
Applications and Limitations
The beauty of the high-low method is in its simplicity. It doesn’t require advanced mathematics or even a calculator; just a keen eye for the most and least extravagant points. However, this simplicity is also its Achilles’ heel. The high-low method takes just two points into consideration, assuming they are representative of the entire dataset. Real life, much like your coffee consumption, is rarely that predictable.
Implications in Business Strategy
Using the high-low method can be akin to using a flip phone in the era of smartphones—it gets the job done but lacks finesse and features. It’s particularly useful for quick back-of-the-envelope calculations or preliminary analyses where getting a rough estimate is more critical than precision.

Remember, while the high-low method can serve as the training wheels of cost behavior prediction, eventually, you might want to upgrade to a more robust bike—that is, a more sophisticated analytical tool. After all, training wheels are helpful, but nobody wants to tour the French countryside with them on.
