How do stacked discounts work?

A second discount is applied to the already-discounted price, not the original. For example, 50% then 20% off equals 60% off in total, not 70%.

Can I calculate the original price from a sale price?

This tool works forward from the original price. To reverse it, divide the sale price by (1 − discount/100).

Does it handle tax?

No, this calculates the discount only. Add sales tax afterwards with our Sales Tax Calculator.

打折后多少钱怎么算？

用原价 ×(1 − 折扣率) 即可。例如 8 折就是原价 ×0.8。本工具直接输入原价和折扣率就出结果。

满减和打折哪个更划算？

分别算一遍再比较最稳妥。满减通常有门槛（如满 200 减 30），打折无门槛，小额订单打折往往更优。

结果包含税费吗？

本工具计算的是折扣后的商品价格，不含税、不含运费，税费请另外估算。
