I have a stream of data that is active and i need to calculate where a number is relative to the percentile range. I have a static 25th,50th,65th, 75th,90th range. When I enter a number I want a calculation to tell me what percentile it is between that range.

Below is my static percentile range. I would like to calculate where what percentile is 5,312 based off of this range. I know about the percentile function but with that one you seem to have to tell it the percentile, I want a calculation that would tell me what the percentile is based off a percentile range 25th to 90th and where it is between those values or sometimes outside of those values.

25th 50th 65th 75th 90th
3,991.71 4933.69 5,472.96 5,896.16 7,066.05

Maybe someone already encountered this issue.

Thanks.
