Formula Used

1) List Price
List Price = Shelf Price × Quantity

2) Discount Amount
Percent Discount = List Price × (Discount % ÷ 100)
Fixed Discount = Entered Fixed Value

3) Final Cost
Final Cost = (List Price − Discount + Shipping) + Tax

4) Usable Weight
Usable Weight = Gross Weight × (1 − Waste % ÷ 100)

5) Price per Weight
Price per Chosen Unit = Final Cost ÷ Chosen Basis Weight

Decision Rule
The lowest final price per chosen unit is the best value.

FAQs

1) What does price per weight mean?

It shows how much you really pay for each gram, kilogram, ounce, or pound. This makes differently sized packages easy to compare.

2) Why use usable weight instead of gross weight?

Usable weight accounts for trimming, bones, peels, moisture loss, or unavoidable waste. It often gives a truer shopping comparison than package weight alone.

3) Can I include taxes and shipping?

Yes. Enter tax percentage and any extra fees. The calculator adds them into final cost before computing price per weight.

4) Which weight units are supported?

You can compare values in milligrams, grams, kilograms, ounces, and pounds. The calculator converts every entry into a common internal unit first.

5) Why can a cheaper package still be a worse deal?

A lower shelf price may hide smaller weight, higher waste, shipping fees, or weak discounts. Unit pricing reveals the real cost efficiency.

6) Does quantity change the outcome?

Yes. Buying multiple packs can improve or reduce value depending on discount size, added shipping, and the total usable weight received.

7) What does the target weight feature do?

It estimates how many packages you need to reach a required amount. It also shows the likely total spend for that target.

8) Can I use this outside grocery shopping?

Yes. It works for pet food, detergent, supplements, coffee, produce, meat, bulk grains, and many other weight-based purchases.
