A Bad Metric for Good Pricing

A Bad Metric for Good Pricing

How do you measure the effectiveness of a pricing transformation? If you invest in improving pricing policy, how will you know that you succeeded in driving improvement? More specifically, how will you prove that a pricing improvement drove profitability? Moreover, how will you demonstrate that an improvement in profit was driven by improving pricing and not some other exogenous or endogenous factor? 

“If you can’t measure it, you can’t manage it” is a common quip. In response, we put metrics on aspects of a business that matter. Moreover, the KISS principle (Keep It Simple Silly) drives us towards using commonly understood metrics. Unfortunately, simple metrics applied broadly leads to everything between clear mandate and a perverse incentive. This is as true for corporate governance as it is for sales incentive plans and even metrics of a pricing transformation effectiveness.

In this article, we look at how I have often seen pricing improvements measured and why I have some serious reservations with this common metric. I do this in the hopes of generating responses on how you accurately measured the effectiveness of pricing at your company.

Profit Drivers

Starting with the standard profit equation of the firm, the profitability in two different periods is defined as

R1 = Q1 (P1 - V1) – F1

R2 = Q2 (P2 – V2) – F2

where R is profit, Q is quantity sold, P is price, V is variable cost, and F is fixed cost. The numbers 1 and 2 denote two different periods, perhaps 1 for the year before a pricing transformation and 2 for the year after the pricing transformation. 

The change in profit between any two periods, DR, would be simply the difference in profits between those periods,

DR = R2 – R1

where we have used “D” to denote the difference between the two years.

Inserting the definitions of the standard profit for the two periods in the change of profit equation, and making some notation changes, we find

DR = DQ (AP – AV) + AQ DP - AQ DV - DF

where we have used “A” to denote the average of the two years.

The above expression deceptively looks like a simple way to disaggregate the impact of improving a business function from overall changes in profits. One might be tempted to assign an increase or decrease in sales impacts profits through the first term DQ (AP – AV), that from a change in pricing through the second term AQ DP, that from a change in costing through the third term -AQ DV, and that from a change in overhead through the fourth term -DF. But this is just as often a deception as it is insightful – which makes it a suspect assignment. 

Don’t Be Deceived 

Consider the impact of an improvement in pricing. Yes, the product of the average quantity sold and change in price does include the difference in prices over the two periods and hence may seem like a good way to measure part of the impact of a new pricing policy, but it is woefully incomplete and misleading.

As long as prices went up, this metric would imply that the new pricing policy improved profits. As such, it perversely provides an incentive for every pricing professional, consultant, and pricing software vendor to always raise prices and decrease discounts, even when higher prices are not justified. While I am all for raising prices when they can be, measuring pricing effectiveness as only about raising prices oversimplifies and misrepresents what good pricing is about. 

Good pricing does not always mean higher prices. It means more accurate pricing. By accurate, I mean prices that accurately reflect the value of the offering to the customer compared to their alternative possibilities, pricing policy that accurately provides discounts and rebates where warranted and doesn’t where unwarranted, prices that accurately capture the firm’s fair share of the value delivered to customers while still encouraging the right target market to purchase.

Sometimes, accurate pricing leads to lower prices. If we always define the profit impact of a pricing improvement as AQ DP, then we would perversely state that more accurate prices which are lower is always bad. This is nonsense.  

We also know very well that price increases are generally associated with volume decreases. If prices went up driving volumes down which in turn drove overall profits down, the simple metric of AQ DP would imply that the pricing project was a success even though it harmed profits.  Conversely, if more accurate pricing led to lower prices but significantly higher volumes which in turn drove profits up, the simple metric of AQ DP would imply that the pricing project was a failure even though improved profit. 

Hence, we must consider the term that reflects the impact of a change in volume on profits, DQ (AP – AV). If all we have is the business factors in the two different periods, we can’t objectively state that any change in volume was due to changes in market conditions, selling effort, or pricing. From basic microeconomics, we strongly suspect that at least some of the change in volume reflects the impact of a pricing improvement effort. How much? We would need to precisely know the price elasticity and this is rarely measurable with any meaningful usefulness at the firm level.  

We might be tempted to ignore this term in evaluating a pricing improvement effort as price changes moderating impact on volume is a secondary effect. Unfortunately, this would quite frequently be a large error. Numerically, I have observed that the term describing the impact of volume changes on profits often dwarfs that of the impact of price changes on profits. Without considering the impact on volume changes driven by price changes, any measurement of a pricing improvement effort will be erroneous. 

Similarly, we could make arguments for including some of the term  -AQ DV in the profit impact of a pricing effort, especially if the pricing effort drove changes in portfolio mix and therefore variable costs. And, if the pricing improvement effort added headcount our software, we would also need to include a portion of the term -DF. How much? We wouldn’t know from just the standard business factors that are commonly measured.

That is: measuring the impact of a pricing improvement effort by the change prices and the the quantity sold alone is deceiving, misleading, oversimplifying, and perverse. It is a bad metric when applied universally.

Ok, now what?

If we can’t simply measure the impact of a price improvement effort between two different periods from business factors alone, then what can we do? What objective metric should we use to measure the impact of all pricing improvement efforts? I can accept that this is a useful metric some of the time, but I also know full well it is a bad metric at other times. And by bad, I mean misleading at best and deceptive at worst. So, what should be used? Another common metric, margin percentage, has even greater challenges.

Why do I care? Increasingly I am hearing from pricing professionals that they have been driving pricing improvement efforts for a number of years and are hitting a ceiling. They say they can’t raise prices any more and expect customers to buy. When prices can’t be raised, a skeptic on the management team will suggest reducing the overhead associated with the pricing department. That is, someone says “I can’t see how pricing is driving profitability anymore. Why not downsize the pricing department and put resources in a better place?” But once they do reduce pricing headcount, they find that pricing decision-making accuracy goes into reverse and thus profits begin to suffer. Rather than let such a misguided approach to management become engrained, I would like to head it off with a good, universally applicable, metric. 

Unfortunately, I don’t have a universally good metric yet. 

Instead, I find reverting to management testimonials and story-telling reveals the truth. This may be more accurate and less deceptive, but it requires accepting nuance. Overriding hard, overarching quantitative metrics with qualitative and detailed facts is never easy, but bad metrics for good pricing can lead to disaster.

This is indeed a tough question, mostly because the world doesn’t stay constant: market and competitor actions can pollute the pure pricing impact. I’ve found two things helpful: one is to measure price increase realization around the time of a price increase. If the increase is at a point in time one has a signal that is unlikely to be confused by something else going on at exactly the same time. The other is to measure “pricing” and not just “prices”. Pricing is measuring the process on the basis that if we do pricing right, prices will follow. It also has the advantage of being a leading indicator. It doesn’t tell you the financial Impact however. Overall measuring the impact of pricing often requires some triangulation.

Tim: Great thoughts as usual. Measuring pricing impact when programmatic changes often need to be done in concert with other efforts such as improving sales force or marketing effectiveness is highly problematic. I have sometimes gone with a version of price-volume-mix analysis as it can account for improvements in business performance due to both price increases and decreases. It also allows for consideration of the impact of complimentary efforts such as improved segmentation and targeting. While the analysis itself is complicated and you can get different "answers" depending how you approach it, it does provide a relatively comprehensive view. The key issue then becomes attributing results with the specific activities that might have driven them. Your approach of using qualitative data and story telling is often the best path. I've found that if management gets overly focused on attribution of results then they are either missing the point or are doing so because of some underlying risk aversion that needs to be surfaced and discussed.
