The price is a range: check whether your child can afford the upper end
By Erik Nilsen · Kroni3 min read
A price stated as a range is not a finished purchase price. The midpoint can be useful for an exercise, but it does not make the highest possibility affordable. Show the complete range and obtain a specific price before ordering.
Calculate three possible payments
In a hypothetical example, your child wants an optional frame for a personal picture. The price list shows 80 to 120 units depending on size and finish. Your child has 110 units. The arbitrary amounts and pricing rule are invented, and your family has not yet received a price for the exact frame.
At 80 units, the amount remaining is 110 − 80 = 30. At 100, it is 10. At 120, your child needs another 120 − 110 = 10 units. All three payments fall within the range, but only the first two fit the budget.
The midpoint is (80 + 120) / 2 = 100 units. It is neither a promised price nor evidence of what is most likely. The range tells you nothing about how often the frame costs 80, 100 or 120.
If planning must cover the full price list, write “unknown, up to 120”. Do not write “100 paid” or deduct 100 from your child's record before anything has actually been purchased.
Ask for the selected option's price
Choose the size and finish together, then ask the seller what that exact choice costs in total. At 108 units, your child can pay and keep 2. At 118, you must change the choice, wait, or agree another specific contribution before purchasing.
A realistic snag is your child already promising to buy the frame because “it costs about 100”. Separate the wish from an order. Explain that you are still considering the purchase until the final price is known. An adult handles actual ordering conditions; this exercise does not establish whether an order is binding.
If keeping at least 10 units matters, the purchase limit is 110 − 10 = 100. The price of 108 then fails the plan even though your child could pay it. Make that distinction visible before choosing.
Ask your family: “Which price do we know for certain, and does the highest relevant amount also fit our plan?”
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.
