Overall Yield from a Multistep Reaction Calculator

Y_overall = Π Y_i / 100^(n−1).

Compute the overall yield of a multistep synthesis as the product of the individual step yields. Up to 5 steps are supported — enter 100 for unused steps. Even high per-step yields drop the overall result quickly: 5 steps at 90 % each = 59 %; 5 steps at 70 % each = 17 %.
