About these tools

These calculators handle the numbers behind everyday pricing and invoicing work. Money is calculated with exact decimal arithmetic and rounded to the paisa, so the totals you see reconcile line by line.

Every result shows its working. You can check how each figure was produced before you copy it into an invoice, a quotation or a spreadsheet.

The tools run entirely in your browser. The amounts you enter are never sent to a server.
