How Inflation Deflates A Law Firm's Bottom Line
I received an email earlier this week from a reader who corrected an error I made when discussing the effects of inflation within the post How Law Firms Can Increase Income By $100k Per Partner In 1 Year. Rather than re-working the example in the original post(where few would notice it), I decided to dedicate a post to the effects of inflation on your bottom line and clarify the point, which was not in error. Considering the overwhelming negativity flowing through the minds of many regarding our current economy, a discussion on inflation's affect on profitability appears ripe anyway.
During the 1990's inflation increased an average of 3% per year. In fact, many of us have become accustomed to using the standard of 3% when adjusting any cost by the rate of inflation. From 2000-2006, inflation was even a little better, increasing on average of only 2.85% per year.

In 2007, the average rate of inflation was still only 2.85%. However, in the last 2 months of 2007, a trend began that is continuing this year. From November, 2007 until January, 2008, inflation has exceeded 4%. On March 14, the February inflation percentage will be released. It will be interesting to see if this trend continues [MARCH 14 UPDATE: Core inflation was unchanged in February - news that, while perhaps temporary, opens the door to another interest rate cut by the Federal Reserve.]. Regardless, January's inflation was highest in the month of January since 1991.

Inflation has actually has been moving up since 2000, except for an interruption after the impact of Hurricane Katrina caused inflation to first spike just after the storm, then drop to under 2% in late 2006. It wasn't until late 2007 that rates returned to the 6 year trend, according to the below chart.

Whether inflation is going to stay at plus 4% in 2008 remains to be seen, but let's just consider the effect of inflation based on the average from 2000-2007 (2.85%). In the following example, annual revenues are $1 million (for simplicity). To determine the effect of inflation on your bottom line, the scenario I am using utilizes fixed margin percentages of 10%, 11%, 15%, 20%, 30%, 40% and 50%. (Using these percentages alone make business owners of other industries indignant, as many can't imagine pulling margins of 50% - though the best performing law firms in the 2007 Law Firm Economic Survey were doing just that) As well as factoring inflation, I also factor in a 6.5% increase in revenue (based on predicted rate increases from firms in the 2007 Survey). Will this offset inflation?
Not hardly. In fact, at low margins, inflation is deadly. If margin is 10%, even with a rate increase of 6.5%, income purchase power is reduced by 22%. Even at 15% margin, your purchase power is reduced 13%. It is not hard to see how small businesses with low margins struggle to survive even moderate inflation.

With margins up to 40%, you are still losing money when revenue increases 6.5% and inflation is as low as 2.85%. However, at least when margins are 40% you are close to offsetting inflation - so long as revenue increases more than double the rate of inflation.
The above model takes into consideration a rise of expenses that includes both inflation and the revenue increase. The assumption is, as Parkinson's Second Law states, that "expenses rise to meet income". When you increase revenue, it is likely due to an investment, whether that investment is additional staff, timekeepers, technology, pay increases, etc. The numbers above change if you only apply inflation to expenses, but that would assume that you are not investing in the above to increase revenue. One way to accomplish increased revenue without additional cost is through increasing productivity, at least in the short term (for those who increase productivity will soon seek financial reward).
In the above, you can see the drastic difference taking "revenue cost" out of the equation. If you can increase revenue without adding cost, inflation is suddenly no longer a threat - all you must do is keep up with the rate of inflation and inflation is abated. In the above, you actually see a higher percentage increase with lower margin. In any event, income across the board goes up. The above, however, is accurate only in the short-term, as costs inevitably increase with revenue.
What can be concluded from this?
- Rate increases must be much higher than the rate of inflation to offset its effects (ie, rate alone isn't a path to increasing income);
- The higher your margin, the less inflation affects income;
- Higher productivity with higher rates can substantially increase income in the short term and minimize its effects in the long run.
For subscribers of the blog, I have attached a spreadsheet with both formulas for you to use to plug in your own numbers and forecast how inflation will affect your profits in both the short run (if you budget for higher revenue without additional cost - such as increasing productivity) and the long run.
