FAQ
- Is the discount applied before or after tax?
- The standard order is discount first: the discount comes off the list price to give the pre-tax sale price, and sales tax is then charged on that reduced amount to reach the final total.
- What if I leave the sales tax rate blank?
- Leave the tax field empty or set it to 0 and you'll get the plain discounted price with no tax added.
- Can it handle stacked discounts applied together (like 20% off, then an extra 10%)?
- The tool is built around a single discount-rate input, so it doesn't handle stacked discounts directly. For a case like 20% off followed by an extra 10%, calculate the first discount, then plug that resulting price back in as the new original price and apply the 10% discount a second time — that gets you the correct sequential result.
