I suppose brevity is the essence, but what's wrong with that? It's easily understood.
I think we are at cross purposes. I meant that this construction:
action, predicted consequence
e.g. Marry in haste, repent at leisure, buy cheap, buy twice, etc,
works well enough if the number of words is not too great, in fact the brevity serves to hammer home the message. However I that it can get unwieldy (and confuse English learners) and give an impression of hasty writing and poor editing if it is used in long complex statements.
Marry without due and mature consideration, for example because of sexual lust or unresolved loneliness or self esteem issues, later on have ample cause to regret the haste with which the union was contracted.
Calculate the average dose energy needed to discumbobbulate the zygote anterior membrane over repeated multiple flange operations, and the cost is prohibitive.
See what I mean? I accept that it is a matter of taste.
In fact the sentence proposed by the OP seems to suggest that the cost that is prohibitive is that of the calculation.
