A setup fee and lower item price: when does the order become cheaper?
By Erik Nilsen · Kroni2 min read
A low price per item can hide a fixed setup charge. For a small purchase, an option costing more per item may therefore cost less overall. Compare identical quantities and keep the setup charge on its own line.
Calculate two orders side by side
In a hypothetical example, your child wants personalised paper prints. Offer A charges 30 units for setup and 3 per print. Offer B has no setup charge and costs 8 per print. These arbitrary prices are invented; both supply the same size and quality for this exercise.
For four prints, A costs 30 + 4 × 3 = 42 units. B costs 4 × 8 = 32. B is 10 cheaper despite its higher item price.
For six, A costs 30 + 18 = 48 and B also costs 48. For seven, A costs 30 + 21 = 51 while B costs 56. The difference per print is 8 − 3 = 5. Six such differences cover the setup charge of 30; only from seven does A become cheaper.
Choose quantity before pricing structure
A practical snag is increasing the order from four to seven to choose the “cheapest” offer. Four from B cost 32; seven from A cost 51. The family pays 19 more and receives three extra prints. That may be a wanted purchase, but it is not a saving on the original four.
First write the number your child actually wants to use. Then calculate both totals for that exact quantity. Check the actual agreement before ordering: a setup charge may apply per order, design or something else. This exercise assumes one setup for all prints.
Ask your family: “How many do we need, and at that quantity does the lower item price cover the setup charge?”
Carry the calculation into your family agreement
Kroni can keep track of your child's virtual balance. The app does not transfer money, so any actual purchase is paid for outside it. Agree on what you will record, then check the amount with your child afterwards. Do not deduct a possible cost as though the purchase had already happened. Read about allowance in Kroni.
