FAQ

Questions Discount Stack Calculator owners ask.

  • 01

    How does percentage stacking work?

    The engine uses a multiplicative approach. For example, applying a 20% discount followed by a 10% discount results in an effective total reduction of 28%, not 30%. Use the percentage_stacking capability to calculate this accurately.

  • 02

    Can I calculate taxes for different regions?

    Yes. The regional_taxation capability allows you to specify whether tax should be applied using 'pre_discount' or 'post_discount' logic, accommodating both US and European VAT standards.

  • 03

    Does it support BOGO promotions?

    Yes, the bogo_logic capability handles patterns like 'buy_one_get_one_free' and 'buy_two_get_one_free', calculating exactly how many units are at full price and the total savings achieved.
