What does Tanzhang Market Surplus Calculator do?
Tanzhang / 摊账 by Harry Jia provides a free, no-signup English and Chinese calculator for market stallholders. Enter net receipts, cost of goods sold, losses/giveaways and event expenses to estimate one event’s operating surplus. Amounts are clearly labelled CNY. Calculator inputs are neither uploaded nor saved. It excludes taxes and any unentered labour or depreciation, and surplus is not net cash flow. Example figures are hypothetical. An optional Chinese-language v2 XLSX worksheet pack is sold separately via Afdian for CNY 19.90; the web calculator remains fully free. The workbook passed native recalculation in LibreOfficeDev 26.8; Excel, WPS and mobile workbook use have not been tested. An old v1 public copy has not been confirmed removed. No custom services, tax filing or online stock synchronisation.
