Price per Unit Calculator

Indian kiranas still win by selling a 750 g pouch that looks dearer than a 500 g pack. ₹100 for 500 units versus ₹130 for 750 units is ₹0.20 versus about ₹0.173 per unit — item 2 is the better value on this page. The display rounds rupees without paise, so read the winner line, not a rounded ₹0.

The price tag, not a checkout

A household in Rajkot comparing oil tins and a hostel warden in Varanasi buying atta in bulk both get tricked by “bigger is costlier.” IndiaKit divides price by quantity twice and names the lower per-unit pack. GST-inclusive MRP is fine; just keep both packs in the same unit (grams versus grams).

Discount and unit maths

Per-unit = price / quantity. Compare a and b. Defaults: ₹100/500 versus ₹130/750 → pack 2 wins. If a quantity is 0, that side is treated as infinitely expensive.

Do not compare 500 g with 500 ml of different densities as if they were the same unit. Convert first.

Festival combos with a free spoon are not in the quantity field unless you assign the spoon a rupee value yourself.

500 g versus 750 g atta in Rajkot

A Rajkot household sees atta at ₹100 for 500 g and ₹130 for 750 g. The calculator names item 2 as better value. They still check the date of packing; a cheaper per-gram pack that expires next week is not a win.

Common questions

Why does the line say ₹0 per unit?

The money formatter rounds to whole rupees. 20 paise becomes ₹0 on that line. Trust the “better value” label and do the paise on paper if you need it: 100/500 = ₹0.20.

Can I compare three packs?

Run the winner against the third pack in a second calculation.

Should I include a bag’s empty weight?

If you care about net grams, use net quantity from Legal Metrology on the pack, not gross.
