Discount Calculator
Calculate Final Price, Savings & Stacked Discounts
Calculate the final price after applying discounts by percentage or fixed amount. Supports double/triple stacked discounts and tax calculations.
🏷️ What is Discount Calculation?
Discount calculation determines the final price after applying discounts to the original price. Stacked discounts (double, triple) are applied sequentially, so the effective discount is less than the simple sum of individual discount rates.
📝 How to Use
- Enter the original price
- Select discount type (percent or fixed amount)
- Enter the first discount value
- Optionally add 2nd and 3rd stacked discounts
- Toggle tax option and enter tax rate if needed
💡 Smart Shopping Tips
- Apply larger discounts first for stacked discounts
- 20% + 30% stacked discount equals ~44%, not 50%
- Tax is applied after all discounts
- Combine coupons with sale discounts for extra savings
- Always check the effective discount rate against the original price
❓ FAQ
Stacked discounts are applied sequentially. E.g.: $100 with 20% + 30% off = $100 x 0.8 = $80 x 0.7 = $56 (total 44% off).
Percentage discounts deduct a proportion of the price, while fixed amount discounts deduct a set value. For expensive items, percentage discounts often save more.
Tax is applied to the final discounted price. So the more discount you get, the less tax you pay.
