Revenue per variant

Every conversion carries the money that came with it, and revenue is attributed to the variant the visitor was in. Values are stored as integer cents rather than floating point, and the total includes tax and shipping as the platform receives them.

It is a goal in its own right rather than a column beside the real one. Significance and intervals are computed on revenue as well as on conversions, so a revenue result can be read with the same standard of evidence as a conversion-rate result.

The implementation queue reads both, in order: conversions first, because that is the primary objective and its maths carries no approximation, then revenue, so an experiment that won on revenue alone still reaches the people who could ship it.

Revenue always needs a currency chosen, and that is not a limitation to work around. Adding kronor to euros produces a number that means nothing, so the console makes the currency explicit rather than quietly summing.
