Calculation result
Formula and calculation method
Total base quantity = quantity per pack × pack count × conversion factor. Unit price = total option price ÷ total base quantity. Equal-quantity saving versus A = (A unit price − lowest unit price) × A quantity.
Worked example
Option A: ₹180 for 750 g → ₹240/kg. Option B: ₹276 for 1.2 kg → ₹230/kg. At 1.2 kg, B saves ₹12 versus buying the same quantity at A’s unit price. For A’s 750 g reference quantity, the saving is ₹7.50.
Assumptions and limitations
Use total price for all packs in that option, not a per-pack price with a multipack total quantity. Prices exclude delivery unless entered. Quality, waste, taxes and package availability can change the practical choice. Weight and volume are different dimensions.

Frequently asked questions
What price should I enter for a multipack?
Enter the total price for all packs, then the quantity in each pack and the number of packs.
Can I compare grams and kilograms?
Yes. Both convert to kilograms. Millilitres and litres convert to litres; weight cannot be compared directly with volume.
