How this calculation works
The invoice generator calculator creates a clear subtotal, discount, tax amount, and total for a single line item. It is useful for quoting work quickly before you prepare a formal invoice. It does not issue a legal invoice, validate tax registration, apply multi-line rounding, or connect to accounting software.
Mathematical formula and logic
Subtotal = quantity times unit price; tax is applied after the percentage discount.
Worked example
One INR 10,000 service at 18 percent tax produces a subtotal, tax amount, and invoice total.
Calculation assumptions
- The tool calculates one line item at a time.
- Discount is applied before tax.
- Tax rate is entered manually and not validated.
- Use compliant invoicing software for records and filings.
