FAQs
Can I apply the same result to differently priced items?
This model uses its stated unit-price assumptions. A basket of differently priced products can produce a different effective discount and needs a corresponding calculation.
Which inputs do I need for BOGO (Buy X Get Y Free) Effective Discount & Margin Calculator?
Use Buy Quantity (Paid Units X); Get Free Quantity (Free Units Y); Regular Unit Price (₹); Unit Product Cost (COGS) (₹). The built-in examples show how those fields fit together.
What should I check before using this result?
Assumes equal unit price across items in the BOGO cart. Check the assumptions and output against your intended task before relying on the result.
