Grocery Shopping Calculator (Total, Budget, Unit Price)

How it works

• Basket: adds price × quantity for a running total and shows what is left of your budget. The list is saved only in this browser.
• Unit price: compares packs of different sizes (e.g. 500 g for ₩4,980 vs 1 kg for ₩8,900) per 100 g, 100 ml or per piece.
• Korean shelf labels show the same “단위가격” (unit price).

FAQ

How do I compare prices of different pack sizes?

Divide the price by the size and multiply by 100 to get the price per 100 g or ml; the lower one is better value.

Worked example

Unit price example: 500 g for ₩4,980 is ₩996 per 100 g; 1 kg for ₩8,900 is ₩890 per 100 g. The larger pack is about 10.6% cheaper per gram — worth it only if you will use it before it expires.

Counting by item: 30 eggs for ₩9,900 cost ₩330 each, while 15 for ₩5,500 cost about ₩367 each. Switch the unit to "ea" to compare products sold by count.

Common mistakes

• "1+1" and multipack deals are not always cheaper; compare the price per gram or millilitre.
• Only compare products in the same unit (g with g, ml with ml).
• Korean shelf labels show unit prices per 100 g, 10 g or per item, so check the base before comparing.
• Use the price you actually pay after coupons.
