Real all-in estimate for 2 travelers over 7 days — including every fee most people forget to budget for.
London is one of the most expensive cities in the world, and most Americans are surprised by the bill even after budgeting carefully. The pound sterling exchange rate, VAT on everything, expensive pints, and the sheer cost of Heathrow transfers all add up fast.

These are the costs most travelers don't budget for until they see the final bill. They're included in the estimate below.
Practical ways to cut your actual trip cost
The Oyster card or contactless bank card is the cheapest way to use the Tube — single fares cap out daily so you never overpay even with unlimited rides.
Many of London's best attractions are completely free: the British Museum, National Gallery, Natural History Museum, Tate Modern, and more. Budget accordingly and save your activity spend for paid experiences like the Tower of London.
US citizens don't need a visa for visits under 6 months, but starting in 2025 you need to apply for an ETA (Electronic Travel Authorisation) for around £10. Small cost but don't miss it.
Most credit cards charge 2–3% on every international purchase. On a $4,620 trip, that's real money. A no-fee travel card costs nothing extra per transaction and often comes with a sign-up bonus worth $500+.
