Common Mistakes to Avoid

Confusing discount percentage with final percentage
A 20% discount means you pay 80% of the original price, not 20%.
Forgetting tax on discounted price
Tax is applied to the discounted price, not the original price. Use the tax feature for accuracy.
Applying multiple discounts incorrectly
Successive discounts should be applied one after another, not added together.
Not checking for minimum purchase requirements
Some discounts require a minimum purchase. This tool calculates the discount amount, not eligibility.

Limitations

Calculates a single discount only (no compound discounts).
Tax rate is a simplification; actual rates may vary.
Does not include shipping costs or other fees.
Not a substitute for professional financial advice.
