This would be the math for 7% annual raises over 3 years.
7% x 2020
14.5% x 2021
22.5% x 2022

Assuming flat wages of 200,000 per year it comes out to $88,000 retro or 44% of an average year.

Two key factors are compounding the raises and applying it to all years of back wages that are owed to the pilots.
