Overview
What is Tanzhang Surplus Calculator?
Know a market event’s surplus after sold-item costs, losses and expenses.
Tanzhang is a free Chinese/English browser calculator for a single CNY market-stall event. Enter net sales after refunds, actual sold-item costs, unsellable losses and event expenses. It calculates operating surplus from those four inputs. Clearly hypothetical examples can be restored for learning.
The free refund tutorial explains why resalable returned stock differs from a refund without goods returned. No purchase is needed to use the calculator or read the tutorial.
This is not tax accounting, a payment processor, a POS, multi-event inventory or currency conversion. The webpage has no dedicated results export or saved history. Mainland access restrictions have been reported; availability varies by network. An optional Chinese workbook is sold separately for CNY19.90, with WPS testing limits disclosed; Excel/mobile workbook compatibility and real paid-order-to-auto-message delivery are unverified.
