How to Read Your Results
The subtotal is the quantity multiplied by the unit price before discounts and tax.
The discount amount is a reduction from the subtotal, not a reduction from the final tax-inclusive total.
The amount before tax is the discounted value used as the tax base in this calculator.
The tax amount is added to the amount before tax to produce the invoice total.
The invoice total is an estimate of the amount due before any separate adjustments such as deposits or expenses.
Assumptions & Important Notes
- All billed units use one unit price.
- The discount applies to the whole subtotal rather than selected invoice lines.
- One tax rate applies after the discount.
- Amounts are shown to two decimal places for illustration.

Frequently Asked Questions
Can I use these examples for an hourly invoice?
Yes. Use hours as the quantity and your hourly fee as the unit price.
What happens when there is no invoice discount?
Enter 0%. The subtotal becomes the amount before tax.
Why is the tax lower after a discount?
In these examples, tax is calculated from the discounted amount rather than the original subtotal.
Can I add multiple invoice lines together?
Calculate each line separately when prices, discounts, or tax rates differ, then combine the appropriate amounts.
