Bulk Buy and Cost Per Unit Sheet

A free printable bulk buying comparison — what you paid, the quantity in the pack, where it was bought and the cost per unit worked out on paper, one line per pack size.

First page of the Bulk Buy and Cost Per Unit Sheet — See whether the larger pack is genuinely cheaper, by putting the shelf prices side by side in the same unit instead of trusting the sticker.

What this sheet is for

See whether the larger pack is genuinely cheaper, by putting the shelf prices side by side in the same unit instead of trusting the sticker.

Who it is for

Anyone stocking a pantry in quantity, households buying from a cash and carry, and small kitchens comparing suppliers.

How to use it

  1. Write the same item on two or three consecutive lines, one per pack size or shop.
  2. Put every quantity into the same unit before you compare anything.
  3. Divide the price paid by the quantity and write the result in the cost per unit column.
  4. Note the date, because a comparison stops being true once the prices move.
  5. Use the notes column for offers, storage and how quickly it gets used.

What is on the sheet

One page, top to bottom:

Printed under the title: Working out on paper whether the big pack is actually cheaper — the price paid, the quantity in the pack, and the cost per unit you get when you divide one by the other.

How to use the last two columns. Write the same item on two or three lines in a row, one line per pack size or shop, and put every quantity into the same unit before you divide. The cost per unit column is yours to fill in: divide what you paid by the quantity, and the cheaper line is obvious. No prices are printed here — they are yours, and they change.

Questions

Why are no prices or unit costs filled in?

Because they are yours, they differ by shop and country, and they change. The sheet gives you the columns and the arithmetic; the numbers have to come off the shelf edge in front of you.

Is cheaper per unit always worth buying?

Not if it goes off first, or if it will not fit anywhere. That is what the notes column is for — a lower cost per unit on something you throw half of away is not a saving.
