The cost planner and checklist need JavaScript. The budget formula is: Known subtotal = item price + domestic shipping + service or payment fee + international shipping + other known costs. Blank fields are excluded. An illustrative example is 24 + 3 + 2 + 18 + 5 = 52 in one hypothetical currency, not a quote.
