I believe it calculates the damage on hit. I think that is the case for different traps such as Teemo mushrooms and Shaco boxes so it would make sense it works like this for all abilities. In the case of dots you can also purchase an item while they are taking damage to gain the effects. For example, if you're playing Brand and you die while your passive is active on someone you can buy a Rylai while dead to slow them. So it would make sense if all damage is calculated when the damage is being done, not when the ability is cast.
