Formula Used

Line Total = Quantity × Rate

Subtotal = Sum of all line totals

Discount Amount = Subtotal × Discount % or Fixed Discount

Tax Base = Taxable Subtotal − Discount applied to taxable amount

Tax Amount = Tax Base × Tax Rate

Grand Total = Subtotal − Discount + Tax + Shipping + Late Fee

Balance Due = Grand Total − Deposit − Paid Amount

Collection Ratio = (Deposit + Paid Amount) ÷ Grand Total × 100

FAQs

1. What does this invoice generator calculate?

It calculates line totals, subtotal, discount amount, taxable base, tax, extra charges, grand total, paid value, and remaining balance due.

2. Can I use percentage or fixed discounts?

Yes. You can choose a percentage discount for flexible pricing or a fixed discount for flat promotional adjustments.

3. Does it support deposits and partial payments?

Yes. Enter both deposit and already paid amounts to see the actual outstanding balance clearly.

Use clear descriptions, accurate dates, itemized charges, taxes, and concise terms. Transparent invoices usually improve payment confidence and speed.
