Calculating prorated value based on a condition

I have the below table.

I need to calculate the annual contract based on the start date and end date of the contract.

As you can see from the above table, the first contract starts at 1 July 2019 and ends at 31 Aug 2019. So the annual contract price for 2019 would be (Comprehensive Price * 60/180) where 60 is the number of days between start date of contract and end date of contract and 180 is the number of days in that year starting from July 2019.

So here is the expected output with calculation for your reference:

The above calculation applies only if we have two contracts falling on the same year with different comprehensive price. On the other hand if you have the below table where there is just one contract a year

the below should be the output:

So for 2017 here, the price is 380 since it is 380*365/365 eventhough contracts starts only from 1 April 2017 and then from 2018 onwards it is prorated. So it will be (380*90/365)+(410*240)/365

How do I create a DAX that satisifes both these conditions?
