How Invoice Calculations Work
Line Total = Quantity × Unit Price Subtotal = Sum of all Line Totals Discount Amount = Subtotal × (Discount% ÷ 100) Taxable Amount = Subtotal − Discount Amount Tax Amount = Taxable Amount × (Tax Rate% ÷ 100) Grand Total = Taxable Amount + Tax AmountCalculation Components
- Line Total: Each item's total computed by multiplying the quantity ordered by the unit price per item.
- Subtotal: The sum of all individual line totals before any discounts or taxes are applied to the invoice.
- Discount: A percentage reduction applied to the subtotal. For instance, a 10% discount on ₹10,000 subtotal saves ₹1,000.
- Tax Amount: Calculated on the discounted amount. GST at 18% on ₹9,000 (after discount) equals ₹1,620 in tax.
- Grand Total: The final payable amount combining the taxable amount plus calculated tax, which is what the client pays.
For example, a freelance web developer in Pune invoicing a client for website development at ₹50,000 with 3 months of hosting at ₹2,000 each would have a subtotal of ₹56,000. With a 5% early-payment discount (₹2,800) and 18% GST on the remaining ₹53,200, the tax comes to ₹9,576, making the grand total ₹62,776. The tool handles all these calculations automatically and displays them clearly on the generated invoice.

What Is an Invoice Generator?
An invoice generator is a professional business tool that helps freelancers, entrepreneurs, small businesses, and consultants create structured, itemized invoices for their products and services. Instead of manually formatting documents in word processors or spreadsheets, an invoice generator automates the layout, calculations, and formatting to produce clean, professional invoices that clients take seriously and process quickly.
Our free online invoice generator is specifically designed for Indian professionals and international users who need a fast, reliable way to create invoices without installing software or subscribing to paid services. It supports Indian GST calculations at standard rates of 5%, 12%, 18%, and 28%, includes GSTIN fields, and offers multiple currencies including Indian Rupees, US Dollars, Euros, British Pounds, and Japanese Yen. This makes it equally useful for domestic billing and international freelancing.
The tool is built by the StoreDropship team with a focus on privacy and simplicity. Every calculation happens in your browser — your business data, client information, and financial details are never transmitted to any server. Whether you are a chartered accountant in Chennai preparing client invoices, a content writer in Jaipur billing for articles, or a software developer in Hyderabad invoicing overseas clients, this tool delivers professional results instantly. The generated PDF invoices are clean, watermark-free, and ready for immediate business use.
