How it is worked out
The published maximum in full at or below the published phase-out threshold, nothing at or above the published amount where it is fully phased out, and in between the same share of the maximum as the share of the range your income has left to run. Rounded to the nearest cent.
It uses Annual IRA contribution limit, $5,500 and Phase-out start, single filers, $120,000 and Phase-out end, single filers, $135,000, published above.
Figures in this colour are computed from the amounts above. They are not published figures and no document states them.
