About this tool
This Invoice Generator turns your inputs into practical results. Provide Tax rate, Discount, and Subtotal to calculate Discount amount and Tax amount.
Adjust values to compare scenarios and see how sensitive the result is. The calculation uses the numbers as entered, so double-check units and expect small differences from rounding in the displayed totals.
