Gross vs net billed revenue
Gross revenue is price times quantity. Discounts reduce the amount before tax in this calculator. Tax treatment varies by jurisdiction, so use the page as a quoting estimate unless local rules are confirmed.
Example
If unit price is 100 and quantity is 50, gross revenue is 5,000. A 10% discount lowers the pre-tax amount to 4,500; a 20% tax on that amount brings the billed total to 5,400.
Common mistakes
Revenue is not the same as profit. Payment fees, product cost, refunds, shipping, tax remittance and labor still need to be considered separately.
Limitations
This calculator does simple line-item arithmetic. It does not decide accounting revenue recognition, VAT or sales tax rules, refunds, deferred revenue or multi-currency invoicing.
