I'm looking for a word for the larger amount from which a salesman's commission might be calculated.
Something like sale price presupposes that his commission is calculated from that particular figure.
I have used principal before because it's a very similar concept to interest being calculated from the principal of a loan, but it's technically incorrect for this purpose.
I've considered dividend (i.e. dividend ÷ divisor = quotient) but this has other connotations
Whereas multiplicand (i.e. multiplicand × multiplier = product) is too obscure.
Anyone got a winner?
