The fact that you try to measure how certain your beliefs are impresses me. I try to do the same thing. I think that's why I no longer believe many of the things I have been told. For example, everyone believes that Jimmy Savile was one of the UKs worst sex cases and I was probably about 90% in agreement with them. But when I started thinking about it and looking at the evidence or lack of it this this certainty went down very quickly. I now believe he is probably innocent.

You don't need any maths to see that I am right. You can do it with a spreadsheet quite easily. Use one column for the new total each year and the other for the principal plus the interest plus the annual payment. But if you doubt me then just put these figures into the input boxes at this site : 0,45000,10,Annual,81

If after doing that you have found that a 99% certainly about a belief is wrong then ask yourself what other beliefs might be wrong?
