Thanks for your illustration, Kevin. Using the figures for yesterday's close:
Quantity 25,000.000
Price $98.656
Current Balance $25,217.51
Using your calculations, I get 101.000067 for the adjusted price using the inflation factor you gave and $98.656 for price. This yields $25,250.01 as the current balance, but they show $25.217.51. Wonder why the difference. I realize this was yesterday's closing.
The index ratio (aka inflation factor) changes daily. The IR for the auction is for the settlement date, 6/30/2022.
There are different ways to get the index ratio, but an easy way for me is to look at the bond details for the quote at Fidelity. For the 4/15/2027, IR for this issue bought today is 1.02319 (this is for settlement Monday 6/27), and the historical IR, which Fidelity says is for yesterday, is 1.02244. Using the IR from yesterday I get adjusted price of 100.869841, and amount of 25,217.46, so within a few cents of number you show.
A complete source for IRs can be found here:

If I make a calculation error, #Cruncher probably will let me know.
