Is the Acceptance Percentage based on 30 days? On 60 days? Fixed or rolling? More often than not, the math doesn't work out regardless of how you run the numbers. You accept a load, or refuse a load, and you watch your percentage do unexpected things. The math doesn't work out. So how is it actually calculated? I put in a call to Research via Driver Relations, and they called me back the next morning with the formula for how it is all calculated.
It is neither a 30-day or a 60-day rolling average, although it could be 60 or even 61 days, and it could be as few as 29 days.
It is calculated using all of the days in the current calendar month, plus all of the days in the previous calendar month.
The only time the average is calculated on 60 days (or 61) is on the first day of a month, before that day has been completed and is in the books. At all other times it is the previous month plus the days completed in the current month.
On March 1st, the first day of March won't be over with until after midnight, so you are dealing with all of February, which is 28 days, and all of January, which is 31 days, so when you look at your percentage as shown on March 1, it is calculated on 59 days.
On March 2nd, you have one full day completed in March, and 28 days for February, so your percentage is based on 29 days.
As of the time of this posting, on March 13, there have been 12 days of March and 28 days of February, for a total of 40 days. When using this formula for calculations, the math works out. Tomorrow, it will be calculated on 41 days. On April 1 there will be 59 days to figure, all of February and all of March. On April 2nd, all of February drops off and it will be calculated using all of March and the first day of April, which is 32 days.
It is calculated based on the number of loads offered versus the number that are accepted, which is not necessarily the same thing as loads offered minus loads refused. In most cases it is, but loads that are offered which are not responded to within the allowable time frame will also count as a load offered but not accepted, essentially counting against you in the same manner as a refusal.
Reduced rate loads and loads offered that pickup more than 8 hours in advance (more than 24 hours on weekends) do not count as a load offered, therefore a refusal will not count against you.
The Driver Web shows acceptance for the last 7, 14 and 30 days, which is great, but it does not show your current true Acceptance Rate that dispatch sees, the one that can be found on the Owner Web, the one that gets used, in part, to determine your board position. So, drivers who do not have access to the Owner Web should probably be aware of how the percentage is actually calculated.

) points out, if you don't know the rules and how the numbers are calculated, you will be shocked a couple of times by dramatic and unexpected variations in your percentage, and will be more likely to just start accepting all loads out of fear that your percentage will suddenly take a dive.
