Step-by-step instructions (English)
- Enter the original price and first discount percentage.
- If applicable, enter a second discount and the tax percentage applied after discounts.
- Compare the discounted amount, effective discount, savings before tax, and final price.
計算式と方法
Subtract the first discount from the original price. Apply any additional discount to the reduced price, then apply tax to the remaining amount. Effective discount compares both discounts with the original price; savings are shown before tax.
使用例
A 2,500 currency units item with 20% off costs 2,000 currency units. Another 10% off reduces that to 1,800 currency units. The combined effective discount is 28%, not 30%.
When this tool is useful
Check a sale offer with stacked reductions or estimate a checkout price before buying. Enter the exact discount sequence shown by the retailer, then compare the final total with the checkout before paying.
Common mistakes and limitations
- Two discounts do not usually add together: 20% followed by 10% is an effective 28% reduction.
- Shipping charges, fixed-value coupons, and store-specific tax treatment are not added automatically.
Practical questions about this tool (English)
Why are savings shown before tax?
Savings compare the original price with the price after discounts. Tax is then applied to the reduced amount, so a final total with tax should not be mistaken for the discounted base price.
Can I use a currency other than the default?
Yes. Select the currency used by your purchase. The selection changes monetary formatting; it does not convert a price using an exchange rate.
