Thanks
This makes sense
I have requested Nedbank to go into my profile and to give me a complete rundown of exactly what is happening.
Since in my case, my Nedbank bond is now directly linked to the interest rate, I would like to know why the amount left over after Payment - Interest - Fees goes to available and not capital and I requested that they change that. I don't want to have money available that in my mind should be reducing capital.
My Absa bond doesn't behave this way though.
The amount left over after Payment - Fees - Interest - A piece for capital goes into available.
You are missing the point. On both of your bonds the total value of (Payment - Fees - Interest) reduces your capital balance. It's illegal for it not to. What is different between the two bonds is how the limit is behaving. In the Nedbank case, your limit is static therefore 100% of the capital balance reduction is available. Your ABSA bond has an amortising limit so your capital balance decreases but the limit also decreases (by a smaller amount) so your available amount goes up but not by the full value of the capital reduction.
E.g. Nedbank bond:
Balance at start of month: 700,000
Limit at start of Month: 750,000
Available at start of month: 50,000
Interest: 5,500
Fees: 69
Payment: 6,500
Balance at end of Month: 699,069
Limit at end of month: 750,000
Available at end of month: 50,931
ABSA bond:
Balance at start of month: 700,000
Limit at start of Month: 750,000
Available at start of month: 50,000
Interest: 5,500
Fees: 69
Payment: 6,500
Balance at end of Month: 699,069
Limit at end of month: 749,500
Available at end of month: 50,431
As you can see, the capital balance is the same and changes in the same way in both cases. It is the limit's behaviour that is affecting the available amount's behaviour.
