📄 Invoice Total
Subtotal, discount, tax and grand total
About this calculator
Build an accurate invoice total in seconds. Enter line items (description, quantity, unit price), apply discounts, and add the correct Canadian sales tax — GST, HST, or GST+PST/QST depending on the province — and the calculator produces the subtotal, tax breakdown, and grand total. It supports percentage or flat discounts per line or on the subtotal, and produces a clean summary you can copy into your accounting software.
Tip: always show the tax as a separate line item — it's required for GST/HST registrants claiming input tax credits, and clients expect to see it.
