FIRE Score Based on safety, healthcare, infrastructure & expat friendliness

London is one of the world's great cities — a global financial capital with unmatched theater, world-class museums, and a dizzying diversity of cuisine and culture. The NHS provides universal healthcare, and the city's public transit system is among the best on earth. However, London is brutally expensive for housing and dining, making it a challenging FIRE destination unless your portfolio is substantial.

Cost of Living Breakdown for London

All cost and FIRE figures assume a single adult.

Lean FIRE Lifestyle

$2.38M

A small 1-bedroom flat in Zone 3 or 4 -- areas like Lewisham, Walthamstow, or Tooting. Cooking most meals at home, with pub meals and market street food as affordable outings. Getting around on a monthly Oyster card. NHS healthcare is a significant financial advantage. London is brutally expensive, so this budget means real constraints on housing size and dining out, but the free museums, parks, and Tube access to the entire city keep life rich.

FIRE Lifestyle

$3.84M

An elegant flat in Kensington, Notting Hill, or a converted warehouse in Shoreditch. Regular dining at top restaurants, premium private health insurance with Harley Street access, and first-class Eurostar to Paris. Royal Opera House season tickets, unlimited Oyster travel, and regular Uber rides. London is one of the world's most expensive cities, so even at this budget housing absorbs a large share, but daily life is genuinely affluent with excellent restaurants, culture, and travel.

Fat FIRE Lifestyle

$11.52M

A grand townhouse in Belgravia or Knightsbridge, or a penthouse overlooking Hyde Park. A cook several times a week, a full-time housekeeper, and full private healthcare with top Harley Street specialists. Business class as default, first class for longer trips. A nice car and driver. Regular fine dining at three-star restaurants. London is arguably the most expensive city on this list, so even at this level the budget has real limits -- but daily life is premium, comfortable, and you rarely think about costs.

Retirement Confidence

The 4% rule is a great starting point. Here we go a step further and test your plan against real market history.

Enter your portfolio on the homepage to backtest a retirement in London against market history.

How this is calculated

This is a real historical backtest. We run your plan through every retirement-length window in US market history (1871–2022): a 75% stock / 25% bond portfolio, rebalanced annually, with withdrawals raised each year for that period's actual inflation. The success rate is the share of those historical start years in which the money lasted the full length without running out.

Your confidence level sets the bar: at Balanced (90%), a survival rate of 90% or more reads "You can retire here", within 10 points below is "Close — worth a closer look", and lower is "Not quite yet". The same level sizes the "Needed to retire here" target. Retirement length also drives it — early retirees planning 40–50+ years see lower survival than the 30-year baseline.
