Fee included or added afterwards: compare completed prices
By Erik Nilsen · Kroni2 min read
Two price labels may show a fee differently. Your child needs to know whether the extra already belongs in the displayed amount or is calculated afterwards. Compare final payments before calling an offer cheaper.
One offer shows a total, the other a base price
In a hypothetical example, an optional personal order costs 110 units at A, including a fee equal to 10 per cent of the base price. B shows a base price of 100 and adds a fee of 10 per cent of that amount. The arbitrary prices and fee rules are invented, with identical contents and no other costs. This is not a tax example or an actual fee arrangement.
At B the fee is 100 × 0.10 = 10 units. The final price is 100 + 10 = 110. A and B therefore require the same payment despite 100 appearing lower on one label.
Do not add the fee again at A. Calculating 110 + 11 = 121 introduces another fee not agreed. To check the base price, calculate 110 / 1.10 = 100. Ten per cent of the total 110 is 11 rather than the included fee of 10.
Label what the amount already includes
A practical snag is comparing A's total with B's base price. Write “completed total” and “before extra” beside the amounts, then calculate a completed total for both.
Neither purchase fits a budget of 105. You need not choose B because its first label falls below the limit. Request the confirmed amount actually payable before ordering.
If the terms use another base or additional charges, change the calculation. Follow the specific agreement.
Ask your family: “Is the fee already included, and which amount is its percentage based on?”
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.
