Six 500ml bottles or three 2L bottles? Compare the cost of the same amount, include multipack offers and percentage discounts, and save your usual buys.
Different packs. One clear comparison.
Six 500ml bottles for 5,900 KRW or three 2L bottles for 8,900 KRW—which is the better deal? Ttakgap is a unit price calculator for grocery shopping. Enter product prices, sizes and pack quantities to compare the cost of the same amount, from bottled water to dish soap and everyday groceries.
Compare on the same basis
Enter one pack’s price, each item’s size and the number of items. Ttakgap calculates the price per 100g, 100ml or item. It converts g and kg, or ml and L, and compares 2–6 products within the same measurement category. See the best unit price and its difference from the highest unit price at a glance.
Include multipack offers and discounts
Apply buy one, get one free (1+1), buy two, get one free (2+1) and percentage discounts together. The calculation uses the total amount you receive and the amount you pay, making bulk packs and special offers easier to compare.
Keep your usual buys close
Duplicate a product and change its price. Current entries save automatically. Name and save comparisons, then reopen your latest 100 from Saved. Delete individual records or reset all comparison data when you choose.
Choose your display
Use Korean, English, Spanish, Portuguese (Brazil), Indonesian, Hindi, Japanese, German or French and follow your device appearance or choose light or dark mode. Select KRW, USD, EUR or JPY for entered prices. Every product in one comparison uses the same currency; changing it does not convert the amounts.
No account required
Calculations and saved comparisons work offline. Product entries and comparison records stay on your device. A Google AdMob banner appears below comparison results; ads and privacy choices use an internet connection.
Ttakgap calculates the prices you enter. It does not retrieve live retailer prices or exchange rates, and does not automatically include shipping, separately charged taxes or conditional coupons. The products and prices above are calculation examples.
