Question 1

How do I calculate allocated prices with this tool?

Accepted Answer

Enter each product's price and quantity, then add any shared fees or discounts that apply to the whole order. The tool spreads each fee or discount across every item in proportion to that item's original subtotal.

Question 2

How are shared fees and discounts split between items?

Accepted Answer

Each adjustment is allocated proportionally by each item's original subtotal, which is its price multiplied by quantity. Items with a larger subtotal absorb a larger share of the fee or discount.

Question 3

Should I enter a discount as a fee or a separate discount?

Accepted Answer

Enter charges that increase the total as fees and reductions that lower the total as discounts. Both are allocated by the same proportional rule, so the difference is only the direction of the amount.

Question 4

Is this calculator free and does it work offline?

Accepted Answer

Yes, it is completely free with no account required. Once the page has loaded it runs entirely in your browser, so it keeps working even without a network connection.

Question 5

Are the prices and quantities I enter uploaded anywhere?

Accepted Answer

No. All prices, quantities, fees, and discounts stay on your device and are processed locally in your browser, with nothing sent to any server.
