常見問題
04Can the discount be more than 100%?
No. A discount above 100% would make the final price negative, so the tool treats it as invalid input.
Does this include sales tax or VAT?
No. It calculates the price after the discount only. Use the Tax / VAT Calculator to add or remove tax.
Can I use this result as financial advice?
No. The result is an informational estimate based on the values you enter. Check the math, fees, taxes, and local rules before making financial decisions.
