Pricing Tier Lookup formula
Here is an interesting twist on the good old VLOOKUP. How to find the pricing applicable for given quantity of a product?
Something like this:
Writing pricing tier lookup formula:
Meet the data:
Let’s say you have data like this:
Assume the data is in a table named pricing
Okay, I am kidding. There is no PLOOKUP formula (P for Price). But we can whip our own version of PLOOKUP using other powerful formulas in Excel.
Let’s say we have product name in cell C6 and quantity in cell D6.
To find the applicable unit price of D6 units of C6 (for example 12 units of Mountain Bikes),
We can use below formula:
=SUMIFS(pricing[Unit price], pricing[Product],C6, pricing[Min. Qty],"<="&D6, pricing[Max. Qty], ">="&D6)
Remember: product prices are in the table named pricing.
How does this formula work?
This is a simple SUMIFS formula that looks at the unit price column of pricing table and sums up all unit prices that match with given product name (C6), with quantity (D6) between [Min. Qty] and [Max. Qty] columns.
In other words, this SUMIFS will narrow down to the one row containing Mountain Bike (11-25) tier and returns the price as $300, if our input is 12 units of Mountain Bike.
Oh wait..! What if the quantity is 32?
You are right, our SUMIFS is too lame to handle cases where the input quantity doesn’t fit in any of the tiers.
But, we can use a simple logic to fix this problem.
Here is the final formula that works in all situations:
=MAX( SUMIFS(pricing[Unit price], pricing[Product],C6, pricing[Min. Qty],"<="&D6, pricing[Max. Qty], ">="&D6),SUMIFS(pricing[Unit price],pricing[Product],C6,pricing[Min. Qty],""))
As you can see, we try to find the MAXIMUM of our original SUMIFS and a second SUMIFS that just looks at given product (C6) and blank value for [Min.Qty] column.
Of course, this assumes that prices go down with each tier. If your case is different, you need to alter the formula.
