History of how NASCAR calculated points through the years – FOXSports.com
In 2011, NASCAR changed the point system again: The race-winner got 43 points, plus 3 bonus points for winning. Second-place paid 42 points, decreasing in 1-point intervals so that the last-place finisher got just one point. Leading a lap was worth 1 point and leading the most laps was worth an additional 1 point.
To accommodate smaller 40-car fields, NASCAR adjusted this formula in 2016 so that the winner gets 40 points, plus 3 bonus points. From there, it decreased by one point per position.
