How is Accuracy Calculated?

I just played a horrible game with a bunch of blunders but got a higher accuracy than a game with with 0 blunders or mistakes. What goes into the calculation? Is it percentage of best moves?

It's a trade secret which chess.com hasn't revealed. There have been many speculations but no one has really quite figured it out.

Evidently...

Because also while reviewing a game's "Key Moments" the engine states there's a better way for Mate. My move gave Mate in 3. The Engine's 'better way'? Also gives Mate in 3....???

It is probably some internal algorithmic functions which we are not aware about. It is possible that you made much more inaccuracies in the second which causes your % accuracy to decrease. Playing a near perfect game in 50 move game with few blunder is more accurate than playing a game with most of the moves being subpar quality.

I asked myself the same question today.  Today I outplayed one of my opponents and checkmated him. But he got a much higher accurancy than me?
