How this calculator works
Line discounts apply before the invoice discount. The selected invoice discount reduces the subtotal and the resulting amount is treated as the taxable base. Tax is illustrative and jurisdiction-dependent; totals are rounded half-up to two decimal places. Enter estimates that match your situation. All amounts stay in the currency selected above, and calculations update locally as you edit.
Example
Use the starting values as a simple example, then replace them with your own assumptions. The results are illustrative and may differ from actual outcomes.
Limitations
This free tool provides estimates for planning and education. It does not account for every lender, tax jurisdiction, contract, fee, or personal circumstance. Verify important decisions independently.
Frequently asked questions
How are invoice discounts applied?
Line discounts reduce their own line first. Then the invoice-level discount reduces the subtotal and the remainder forms the taxable base.
Is this tax-compliant everywhere?
No. Tax rules vary by jurisdiction, product, customer, and invoice. This calculator uses one illustrative convention only.
Can I send this invoice?
No. This public calculator does not store or send invoices. Use the authenticated GridHub invoicing tool to create and manage invoice records.
