Global Blue Tax Refund Calculator: What You Actually Get Back
Tax-free shopping returns part of the VAT included in a purchase to visitors who export the goods. The headline VAT rate is never what lands in your account: VAT is a share of the pre-tax price, and refund operators keep a commission on top.
The two-step calculation
- Extract the tax: VAT paid = gross price ÷ (1 + rate) × rate. At 20%, a 1,000 purchase contains 166.67 of VAT, not 200.
- Deduct the commission: operators typically retain 30-50% of that tax, so the cash refund on 166.67 is often 85-115.
- Net effect: expect roughly 8-13% of the purchase price back on a 20% VAT country, less if you take cash.
Conditions that apply almost everywhere
You normally must be resident outside the tax area, spend above a minimum threshold in one store on one day, request the tax-free form at the point of sale with your passport, and have the form validated by customs when you leave with the unused goods in your luggage. Missing the customs stamp is the most common reason a refund never arrives, and validation windows are usually about three months from the date of purchase.
Cash desk or card refund
Airport cash desks pay immediately but charge an extra fee per form and often use an unfavourable exchange rate, so the same purchase can be worth noticeably less in cash than by card. Card refunds take several weeks but avoid both deductions. If you are refunding several forms at once, the per-form cash fee compounds quickly.
