PricePen Unit Price Calculator

Is the bigger pack really cheaper? Is today’s price better than last time? PricePen helps you answer both. Compare unit prices while you shop. Then record a price worth remembering, so your next decision starts with your own history. COMPARE THE SAME AMOUNT Enter each option’s price and pack size. See which costs less per unit and the cost difference for the same quantity. Compare g with kg, oz with lb, ml with L, or price per item. Compare multipacks and include percentage discounts, fixed-amount discounts, or bundle prices. REMEMBER ONE PRICE FOR NEXT TIME Save a selected price under an item name, with an optional store note. Choose an existing price note to keep its history together. You can link a note during a comparison without clearing what you have typed. SEE WHAT CHANGED AFTER SAVING When a comparable earlier record exists, see how the price you just recorded differs from it. Higher prices can be recorded too. Review dated entries, your recorded minimum and your personal price range before your next grocery trip. LOOK BEYOND THE STICKER PRICE A smaller pack can hide a higher unit price. Confirm that two records are for the same product under matching conditions to check changes in pack size and unit price. START WITH A SIMPLE EXAMPLE Try the optional first-run example, or skip straight to your own prices. PricePen supports English, Korean, Japanese, French, Spanish and Brazilian Portuguese. Prices are entered manually and records stay on this device. Your recorded minimum covers only your own comparable entries, not live store prices. Ads may appear.
