Example 1
- Direction: net → gross
- Net amount: 1000
- Rate: 7%
Tax 70
Gross 1070
VAT / sales tax: 1000 net at 7% → tax 70, due 1070.
VAT Calculator
Enter an amount and a combined US sales-tax rate. From 1000 net at 7%, tax is 70 and the amount due is 1070. Under Extra options you can add quantity, a discount before tax, or reverse a receipt total. In the US this works like a sales-tax split: net, tax, and total.
Result
Net → Gross is on. Enter the net amount and rate. Tax and gross appear here.
Take-home pay is on net to gross pay. Here you split a price into net, sales tax, and gross — not income tax on a paycheck.
How results are calculated
Net1000
Rate7%
Tax70
Gross1070
The United States has no federal VAT. This page still splits one amount into net (the pre-tax price), the tax line, and gross (what the customer pays). In US retail that tax line is sales tax, usually added at the register. The starting rate is 7% — a round combined example, not a nationwide law. From 1000 net at 7%, tax is 70 and the amount due is 1070, the same as multiplying by 1.07.
Net → Gross is the usual path when you know the shelf or quote price before tax. Gross → Net removes tax from a tax-included total by dividing by 1 + rate/100. Tax → Net and gross treats the amount field as the tax line alone: net = tax × 100 ÷ rate, then rounded to the cent. At a 0% rate there is nothing to divide by, so the calculator will not run that direction. After rounding, more than one net can produce the same tax, so reversing tax does not always recover the original quote.
Optional quantity multiplies the base before tax. A percent discount, if you enter one, first reduces the chosen amount, then tax is computed. Amounts are rounded to the cent, so tax taken from gross with rate ÷ (100 + rate) can differ by one cent from tax from net. The table under the result shows the same net at typical combined rates such as 0%, 6%, 7%, and 8%.
The result is only multiplication or division by the rate you enter. There is no EIN, state, ZIP code, or filing export. A 0% rate on this page does not decide whether a sale is exempt. Take-home pay belongs on net to gross pay — that rate is income tax on wages, not sales tax on a receipt.
How to use
- In step 1 choose I know net, I know gross, or I know tax.
- In step 2 enter that one amount. The hint under the field says whether it is net, gross, or tax alone.
- In step 3 leave 7 as a round combined example, tap a rate button, or enter your city rate in Sales tax rate (%).
- Optionally, under Extra options, enter quantity and a percent discount before tax. An empty quantity means one unit; an empty discount means 0%.
- Click Calculate. From 1000 net at 7% you should read 70 tax and 1070 gross.
Formula
tax = net × rate / 100 (rounded to the cent)
gross = net + tax. At 7% that is also net × 1.07. From gross: net = gross / (1 + rate/100). From tax alone: net = tax × 100 / rate. A discount reduces the chosen amount before tax. Quantity multiplies that same base.

Frequently asked questions
What is a VAT calculator on this page?
The calculator converts net, tax, and gross at a rate you enter. At 1000 net and 7% the tax is 70 and the amount due is 1070. You can add quantity, a pre-tax discount, or reverse a receipt total. Not a sales-tax return.
Is this also a sales tax calculator?
Yes for US use. The math is the same add-on percent: net × rate/100. Defaults use a combined sales-tax style rate, not a European 20% VAT invoice.
How is sales tax (or VAT) calculated from a net amount?
At 1000 net and 7%, tax is 70 and gross is 1070. The calculator multiplies 1000 × 0.07 = 70, then adds 1000 + 70 = 1070. Seven percent is a round combined example, not a federal rate.
Does the United States have VAT?
No federal VAT. US states and localities levy sales tax, usually on the pre-tax price. This page keeps the title VAT calculator and uses that same net / tax / gross split for a US sales-tax rate you enter.
How do I reverse a gross receipt to net?
Divide gross by 1 + rate/100. At 7% you divide by 1.07. 1070 ÷ 1.07 = 1000 net, and tax is 70.
Why can tax from gross and tax from net differ by one cent?
The calculator rounds to the cent. Tax from gross is gross × rate ÷ (100 + rate). After rounding, that fraction and tax from net can differ by one cent. The check field shows both numbers.
Does 0% mean the sale is exempt?
In this formula tax = 0 and gross = net. A legal exemption and a 0% rate you type are not the same thing. The calculator only applies the rate you enter.
Can I book this into a sales-tax return?
No. There is no EIN, state, ZIP code, or product category. This is a quick way to split an amount, not a filing. Bookkeeping needs a system or an accountant.
Is this a European VAT return tool?
No. It is a net/gross percent converter. It does not file VAT returns, OSS, or US sales-tax remittance.
How is this different from net to gross pay?
Here you have sales tax on a price. There you estimate take-home pay: income tax, optional social charges, and a flat other amount. Different fields, different formula.
Does the header currency multiply the result?
No. The amount stays the same figure. The symbol only labels the result. A comma and a period in an amount mean the same thing.
Knowledge sources
The calculator multiplies the amount by the combined US sales-tax rate you enter. It splits the price; it is not a state filing.
