Okay, so, obviously, the reader, Y/n, is incredibly strong so, here's a quick break down.
Current Base Y/n > Current Base Goku and Vegeta
Super Saiyan Goku/Vegeta > Kaioken Y/n
Kaioken times 20 Y/n > Super Saiyan Goku/Vegeta
Super Saiyan 2 Goku/Vegeta > Kaioken times 20 Y/n
Kaioken times 100 Y/n > Super Saiyan 2 Goku/ Vegeta
Kaioken times 100 Y/n > Super Saiyan 3 Goku
Kaioken times 100 Y/n = Super Saiyan God Goku/ Vegeta
Super Saiyan Blue Goku/Vegeta > Kaioken times 100 Y/n
UI Omen Y/n > Super Saiyan Blue Goku/ Vegeta
UI Omen Y/n > SSGSS Kaioken times 10 Goku
UI Omen Y/n ≈ Vegito Blue
Ultra Instinct Y/n > Vegito Blue
So, Kale is roughly equal to Kaioken times 3 Y/n, but Kaioken times 4 Y/n wipes the floor with her. So she's around Super Saiyan Goku/Vegeta level for reference. I just got the urge to do this, this isn't necessary to read, it's hardly important to the story because like a wise man once said " Power levels are bullshit! ".
