Sorry, I forgot to add that the regular payments cover mostly interest charged each month with small principal amounts left over.

Is A's payment all principle, or is some of it interest?
Knowing the exact amounts of the payments that reduce the principal is necessary to make accurate calculations.

Each person's payment only reduces the principal by about $10.  $290 of the $12,000 is interest.

Recalculate "After monthly payments" using the amounts actually applied to the principal.
Then calculate the percents.

Thanks, Mark.  I think I just needed to think it through with someone else.
