the correct amount of trs is being paid.
218,000 * 1.65% = 3597 interest per year
3597 * 30% = 1079.10 trs per year
1079.1 / 12 = 89.92 trs per month.
your wife has a trs ceiling of 3,000
you have a trs ceiling of 10,000
total is 13,000
but as your interest is less than the ceiling, the ceilings are not relevant at this time.
in 2015 your ceiling will reduce to 3,000
you wife will still have a ceiling of 3,000
the total ceilings of 6,000 will continue until the end of 2017
