Free business calculators.
A growing library of free, no-signup calculators for finance, sales, and procurement teams. Built by the Procupy team.
Each calculator does one sum in the browser. There is no account. They are the arithmetic a buyer or a finance colleague already does on paper: add or remove GST, estimate TDS, turn a cost into a selling price, or see whether freight and tax change which vendor is cheaper.
The GST calculator and the TDS calculator use the rates you type. They do not file a return. Margin, markup, discount, ROI, break-even, EMI and inventory turnover are general commercial sums, and the landed cost calculator adds freight, duty and handling to a product cost. The quotation comparison tool lines up to five vendors on the same basis and exports a sheet. The MSME delayed-payment interest calculator applies the section 16 formula to dates and a bank rate you enter. It does not look up today's rate, and it is not tax advice.
