Enter item price and usage count to see cost per use and value grade
Value grades are general guidelines and may vary by item category.
When buying things, 'how many times will I use it' matters more than the sticker price. Divide the price by usage count to find the real value.
Based on cost per use: S (<₩500), A (<₩1,000), B (<₩3,000), C (<₩5,000), D (≥₩5,000).
Daily=30/month, 2-3×/week=10/month, weekly=4/month, monthly=1/month.
Electronics, clothing, sports gear, subscriptions — any repeatedly used item.
