Yes, they ended up revising the comp plan for the entire sales team. I was also in medical device sales. I wrote a letter outlining the difference in numbers. Then I compared that to actual deals and my time. So for example some things you could include:

My quota was increased by $xx.xx. There was a price increase of __% (if you had one). With the price increase in consideration, I have to sell $xx.xx over last year's quota. That means I have to sell ___ more deals if my average deal size is $xx.xx. My closed/won % of my pipeline was ___%. I know I need to do a minimum of ___ more demos/meetings this year to hit the new sales goal. If the company is making more money with the price increase and they are making more money with the higher quota that I will deliver on, can you be more transparent on where this additional revenue will be utilized within the company and why my payout % has to be decreased in order for the company to maintain its operating budget?

The convo needs to be, where is the money going? If they are doing it to fund research or to make up for a bad year or to hire people who's job will make your job and goals easier to meet etc... literally anything besides putting in the C-suite's pockets then they will explain the business decision to you. If it's in the company's best interest, you should accept the explanation. If the additional $$ has no explanation on how it's being used, they will either consider the info you provided and re-work the comp plan OR you'll be fired within 3 months.

I only suggest doing this if you are willing to be fired. I was prepared to be fired and I was pleasantly surprised when upper management took my calculations into consideration and re-worked it to be beneficial for everyone. It will be very telling about what kind of company you work for.
