VAT: adding it and pulling it out of a price
VAT, which is charged at each step from production to sale even though you see it as a single rate printed on the shelf price, moves along the chain as businesses add it to net prices when they issue invoices and pull it out of gross prices when they need to see the real net underneath, a two-way need that is exactly why the calculator gives you both directions instead of forcing you to do the reverse math by hand.
TL;DR
- Unlike a general sales tax, which in the United States is only collected once when the final consumer buys the product at the till, VAT is collected incrementally throughout the supply chain, which means at each stage the seller adds VAT to the sales price, collects it from the buyer, subtracts the VAT they previously paid on their own inputs, and remits only the difference to the state, while the end consumer, who cannot reclaim the tax in the same way a business can, ultimately bears the full cost, a mechanism that sounds more complicated than the single calculation you actually need to run when you just want the net or the gross.
- Formula: Adding VAT: Gross = Net × (1 + (VAT Rate ÷ 100)) | Extracting VAT: Net = Gross
- Example 1: Adding 22% Italian VAT to a net invoice
How it works
Unlike a general sales tax, which in the United States is only collected once when the final consumer buys the product at the till, VAT is collected incrementally throughout the supply chain, which means at each stage the seller adds VAT to the sales price, collects it from the buyer, subtracts the VAT they previously paid on their own inputs, and remits only the difference to the state, while the end consumer, who cannot reclaim the tax in the same way a business can, ultimately bears the full cost, a mechanism that sounds more complicated than the single calculation you actually need to run when you just want the net or the gross.
The math
VAT work splits into two practical operations, adding VAT to a net amount to get the gross and extracting VAT from a gross amount to get back to the net, and while adding is the straightforward part, just net times one plus the rate, extracting is where most people slip because it requires a careful division, gross divided by one plus the rate, rather than a simple subtraction that always produces a figure that looks plausible but is off by enough to matter on an invoice.
To add VAT, convert the tax rate to a decimal, add 1, and multiply by the net price. To extract VAT from a gross price, divide the gross amount by 1 plus the tax rate as a decimal. The absolute tax amount is the difference between the gross and net prices.

VAT in practice: reverse, rates & costly slips
When you search add VAT vs remove VAT or reverse VAT, the real question is direction. Adding is net ×1.20, but extracting VAT is gross ÷1.20, not gross −20%. A 22% reverse on €122 done as 22% of gross gives €26.84 vs correct €22. For reduced rates (4%/10% IT, 5.5%/20% FR) or quarterly VAT prepayment, use the reverse correctly.
| Case | Net | VAT 22% | Gross |
|---|---|---|---|
| Add | 100,00€ | 22,00€ | 122,00€ |
| Extract | 100,00€ | 22,00€ | 122,00€ |

Examples
Example 1: Adding 22% Italian VAT to a net invoice
- Identify the net service value: €500.00
- Identify the applicable VAT rate: 22%
- Convert tax rate to factor: 1 + (22 ÷ 100) = 1.22
- Calculate gross invoice price: €500.00 × 1.22 = €610.00
- Calculate tax amount: €610.00 - €500.00 = €110.00
Example 2: Extracting (scorporating) 20% UK VAT from a gross bill
- Identify the gross purchase amount: £120.00
- Identify the applicable VAT rate: 20%
- Convert tax rate to factor: 1 + (20 ÷ 100) = 1.20
- Divide gross to find net price: £120.00 ÷ 1.20 = £100.00
- Isolate the VAT tax amount: £120.00 - £100.00 = £20.00
When to use it
✦ Freelance Invoicing and Compliance
Freelancers and companies must prepare compliant invoices for clients. They must list the net cost, the exact VAT rate applied, the calculated tax amount, and the final gross total due.
✦ Reclaiming VAT on Business Expenses
Registered corporations can often reclaim the VAT they pay on raw materials and business operations. Bookkeepers must extract the exact VAT amount from receipts to claim these tax credits.
✦ Cross-Border International Trade
Importers and exporters deal with complex tax rules. Understanding VAT allows companies to calculate land costs, declare customs values, and price products competitively in foreign markets.
⚠ Common mistakes
- Direct Multiplication Subtraction: The most common invoicing error is trying to subtract VAT by multiplying the gross amount by the percentage. For example, subtracting 20% directly from a gross price of £120 results in £96 (which is incorrect!). The correct net price is £100, and the correct VAT amount is £20. You must always use division to extract tax.
- Using Incorrect Regional Rates: Applying the wrong local tax rate can lead to audits, tax penalties, and billing disputes with clients. Always double-check current official tax rates.
FAQ (7)
What is the difference between Net and Gross price?
The net price represents the cost of an item before taxes are added. The gross price is the final amount, which includes the net cost plus the calculated tax.
Can individuals reclaim VAT on shopping?
Standard citizens cannot reclaim VAT on daily purchases. However, international tourists can often claim a VAT refund at airport customs when leaving a country.
Why do tax rates differ between products?
Many governments apply lower VAT rates (like 4% or 10%) to essential items like fresh food, books, and medical supplies, while luxury goods face standard standard rates (like 22%).
If I type my salary or prices here, do you store them?
No — and that's deliberate. Everything runs locally in your browser, nothing leaves your device. We don't see your net salary, your margins, or the VAT numbers you test. For a finance tool that matters: you can run a quick check on a payslip or an invoice while on public Wi-Fi and close the tab knowing no trace is kept server-side.
Can I use it on the train without signal to check an invoice?
Yes. Load the page once, then it works offline. VAT, discount and mortgage math are all pure JavaScript — no API call. I often test it in airplane mode: open the mortgage page, type 250,000 at 4.5% for 25 years, you get the schedule instantly, even in a tunnel.
Can I file taxes with these results?
Use it as a fast sanity check, not as the final filing. Formulas are standard (e.g. Net = Gross / 1+VAT) and verified against official sources listed at the bottom, but rates and thresholds change — Italy's 22% vs Germany's 19%, or IRPEF brackets. For the actual declaration, double-check with your accountant or Agenzia delle Entrate / HMRC / IRS.
How do I send a calculation to my accountant?
Hit 'Share Link' under the results. It encodes the inputs in the URL — e.g. ?price=1200&vat=22 — so your accountant opens the exact same view, no screenshot needed. You can also copy the result with one tap and paste it into an email.
