Type in the base amount — the price before any tax or discount is applied. This could be a product price, a service invoice total, or an order subtotal from your e-commerce store. For a full invoice with line items, use our Invoice Generator — it handles everything including tax in one place.
Pick one of the preset buttons (5%, 8.5%, 13%) or type in any custom rate — including decimals like 6.25% or 17%. If there's a discount involved, add that percentage too. The calculator always applies the discount first and then calculates tax on the reduced amount, which is the standard accounting method used worldwide.
The result updates instantly — you'll see the subtotal, discount amount, tax amount, and grand total all laid out clearly. Hit the Download button to save a timestamped text report. That's useful for bookkeeping, client invoices, or just keeping records of your calculations.
If you've ever been confused about whether you're dealing with Sales Tax, VAT, or GST — you're not alone. Different countries call the same basic concept by different names, and the rates vary quite a bit. Here's a clear breakdown of what each one actually means, and what rate to enter for your country.
In the US, sales tax is charged at the point of sale and varies by state — sometimes even by city or county. There's no federal sales tax. Common rates range from 0% (in states like Oregon and Montana) to around 10% in places like Tennessee. California sits around 7.25% as the base state rate, but local additions can push it higher. If you're selling online across state lines, you enter the rate for the buyer's state. The calculator handles any rate you type in — just look up your specific state rate and enter it directly.
VAT is used across Europe, the UK, Australia, and many other countries. Unlike sales tax, VAT is collected at each stage of production, but the end consumer pays the full amount. Standard rates in Europe typically range from 17% to 27% — Hungary has one of the highest at 27%, while Germany and France sit at 19–20%. The UK's standard VAT rate is 20%. Australia uses GST at 10%. The math is identical to sales tax — just enter the percentage that applies in your country.
GST is the name used in Canada, India, New Zealand, Singapore, and several other countries. In Canada, the federal GST is 5%, but provinces add their own PST or HST on top — Ontario's combined HST is 13%, for example. India's GST has multiple slabs: 5%, 12%, 18%, and 28%, depending on the product category. Pakistan charges GST at 17% as the standard rate. New Zealand has a flat 15% GST. For any of these, just type in the applicable rate and the calculator does the rest.
If you're a freelancer billing international clients, you typically need to apply your own country's tax rate — or no tax at all if the client is in another country and you're exporting services. For example, a Pakistani freelancer on Upwork or Fiverr billing a US client usually doesn't charge GST on that export. But a freelancer billing a local Pakistani business needs to factor in 17% GST if they're registered. When in doubt, check with a local tax professional — this tool just handles the math once you know the right rate to apply.

Most people doing freelance work, running a small online store, or managing business invoices need to calculate tax dozens of times a week. Spreadsheets work but they're clunky. A full accounting platform is overkill for a quick calculation. A calculator buried in an ad-heavy page wastes your time. This tool exists for one reason: give you the correct breakdown instantly, let you download it if needed, and get out of your way.
Whether you're a Daraz seller working out GST on a product listing, a freelancer adding VAT to a UK client invoice, a Shopify store owner calculating US sales tax, or an accountant double-checking a quick figure — the math here is the same. Enter your amount, enter your rate, get your answer.
Tax calculations come up in more situations than most people expect. Here's a look at the most common use cases this tool handles well, from everyday shopping to professional invoicing.
If you're selling on Daraz in Pakistan, you need to add 17% GST to product prices when issuing tax invoices to registered buyers. If you're on Shopify selling to customers in multiple US states, each state has a different rate — you look it up, enter it here, and get the number you need for the order total. Amazon FBA sellers often need to verify the tax already calculated by the platform — this tool is quick for that spot-check.
Freelancers on Upwork, Fiverr, or working directly with local businesses often need to add a tax line to their invoices. A Pakistani freelancer billing a local company might need to add 17% GST. A UK-based freelancer adds 20% VAT to domestic client invoices. A Canadian freelancer might add 13% HST for Ontario clients. Enter your service fee as the subtotal, add your applicable rate, and the breakdown is ready to copy into your invoice. Combine this with our Invoice Generator for a complete professional invoice.
A shop owner quoting a price to a customer, a contractor estimating a project total including tax, a retailer calculating the final price on a discounted item — these are everyday situations where a quick, reliable calculator matters. The discount feature is particularly useful for retail: apply 20% off first, then add sales tax on the discounted amount, which is both the standard practice and how customers expect the math to work.
For accountants verifying client calculations or students learning how tax formulas work, this tool shows the complete breakdown — taxable amount, tax rate applied, and grand total — in a clear, transparent format. The downloadable report is useful for audit trails. For students, seeing the formula applied to real numbers makes the concept concrete in a way that textbook examples often don't.
Buying something online from another country and wondering what the final cost will be including import VAT? Planning a purchase in a country with a different tax rate than you're used to? Just enter the item price and the destination country's VAT/GST rate to see what you'll actually pay. It's a quick sanity check before you commit to a purchase.
