Calculating interest from debt on the claim

[Claimant]

I am owed 10K - debt and 1K agreed interest on debt (10%). I am working on the MCOL and cant figure out how to calculate the interest that i need to claim.
I envisage that I would have to go via attachment to earnings route, and it is hard to predict how many months it might take. I, obviously want the interest on 11K to be paid up until the moment the debt is paid in full, but I can’t see how I can communicate it on the MCOL form.
appreciate any advice!

Thank you for your response! Of course I have read it before asking a question here. It doesn’t describe my situation. I want to claim 10% on 10K according to my agreement, then, from the moment the debtor defaulted, 10% on 11K until the debt is paid. It is not a specified amount, as I don’t know how long it might take him. It is possible that I am not getting something in a way its explained.
