I got my kidney transplant last years. Here are some of the allocation calculators used in the US. https://optn.transplant.hrsa.gov/data/allocation-calculators

For kidney transplants, for example the EPTS score, compatibility, time on the list, geographic distance and antibody levels are used to generate the wait list ranking. For scale, you accrue 1/365 points for each day waiting on the list. Kids under 10 get 2 extra points. Kids under 20 get 1 extra point. Those with high antibody levels can get up to 20 extra points to increase their chance of getting a match.

The KDPI score is an estimate of how risk of graft failure of the donor organ. The lower the number the better the odds. Those with low EPTS (<20%) will get those with KDPI <20%. Age and diabetes heavily factor in an EPTS score. The donor KDPI is something they will tell you when you get a call. You can always pass on any donor organ.
