Teired rates

[Normanbykid]

Hi

Just need some help with a formula. We sell 150 units at 0.25 cents then after 150 the price is reduced to 0.10 cents. We can get excel (2013) to calculate 150 at 25 but cannot get a formula to calculate unit price of 10 after 150.

Many thanks

Try this, assuming the number of units is in A2

=SUMPRODUCT(--(A2>{0;150}),--(A2-{0;150}),{0.25;-0.15})

[Bob Phillips]

In this case, because you only have two variable rates, this might be simpler

=A2*0.1+MIN(A2,150)*0.15

[Bob Phillips]

Or even

=MIN(A2,150)*0.25 +MAX(0,A2-150)*0.1
