Revenue Reporting over the new year

I'm trying to answer the simple question, "How much revenue did your projects generate in 2022, compared to the potential revenue of your projects in 2022."  However, I have a problem because some of my projects started in 2021, but will carry over to 2022. 

For example, if a project started in 2021 is worth $100k, and on December 31st it is 80% complete, $80k worth of revenue has been counted in 2021. However, I don't want my 2022 report to show the full $100k of potential revenue when I will only be able to realize $20k this year.

Is there a way to show that only $20k of that $100k is potential revenue for 2022?
