Wise (formerly TransferWise) is the standard for transparent international money transfer. UK businesses regularly save 60-80% vs bank international transfers. Calculator above shows the per-transfer cost; below explores the wider use cases.
The transparent-fee model
Wise charges: 1. Small fixed fee (typically £0.40-£1.50) 2. Variable percentage based on currency pair (0.4%-0.8%) 3. Mid-market FX rate (the rate banks use between themselves — no hidden margin)
Banks typically charge: 1. Flat international transfer fee (£20-£25 SWIFT fee) 2. FX margin built into exchange rate (1-3% hidden cost) 3. Receiving bank fee (sometimes £5-£15 on the other side)
The hidden FX margin is what makes traditional bank transfers expensive. Wise’s transparency reveals it.
When to use Wise
- Paying overseas suppliers (UK to international supplier in their local currency)
- Receiving payments from international customers (multi-currency account with local account details)
- Travel/relocation (Wise debit card for low-fee overseas spending)
- International payroll (paying international contractors at fair FX rate)
- Tax obligations in multiple countries (paying foreign tax bills at fair FX)

Tax considerations for UK businesses
International transactions can trigger:
- VAT on imports (above £135 from outside UK, or any from EU since Brexit)
- Customs duties (depending on product type and origin)
- Tax on overseas-source income (UK self-employment income from international clients still UK-taxable)
Wise transfers don’t change tax treatment — but they make tracking easier with clear transaction records and FX rates documented.
What this calculator doesn’t model
- Volume discounts (Wise Business offers reduced rates above £100k/month)
- Receiving-bank fees on the destination side
- Instant-transfer surcharge (extra fee for immediate vs standard 1-2 day)
- Multi-currency ‘hold’ usage (no conversion = no fee)
- Wise debit card spending fees
