Question 1

How do I calculate the total after tax and discount?

Accepted Answer

Enter your base amount and line items. The simulator applies discount before tax by default and updates the current total instantly.

Question 2

Should tax be applied before or after discount?

Accepted Answer

This simulator uses a clear default order: discount first, then tax. The order is shown in the results summary.

Question 3

Can I add multiple line items and see each item’s contribution?

Accepted Answer

Yes. Each line shows its parsed amount and its contribution to the current total.

Question 4

What happens if I enter a negative value?

Accepted Answer

Negative values are allowed where useful, and invalid numeric input is highlighted with an error message instead of crashing the page.

Question 5

Can I copy or share the result without creating an account?

Accepted Answer

Yes. The page provides a shareable plain-text summary and a copy button, with no login required.
