Frequently Asked Questions

3 answers
Can I enter pounds or Canadian dollars?

Use one currency consistently for the input and interpret both outputs in that currency. The tool performs arithmetic, not currency conversion.

Does the final price include tax or shipping?

No. Only the entered price and discount percentage are used.

Can I combine two discount percentages?

There is one discount field. Sequential discounts apply to successive reduced prices and should not simply be added together.
