This form calculates estimated post-tournament ELO ratings using the exact, not the approximate, USCF formulas. The rating is still estimated, though, because the USCF calculation is done in two passes and requires the complete tournament cross-table.

In the results box, enter your tournament results, game by game, using 'w' for win, "l" for loss, and "d" for draw, and then giving the opponent's rating. Leave a space between each game. So if you won a game against a 1313 player followed by a loss to a 2090 player and a draw with a 1589 player, enter

w1313 l2090 d1589

If the event is half-K, or you played the same opponent more than once, check the appropriate box; likewise if all of your prior tournament games were wins or losses, check the matching box.
