Why we build these
Answers you can't get from a guidebook
Most London travel advice stops at “get an Oyster card”. That leaves the questions people actually have unanswered: will four days of sightseeing cost me £35 or £90? Does the weekly cap help if I arrive on a Thursday? Is it really faster to take the Tube one stop?
Those are arithmetic problems, not opinions, so we built calculators rather than writing another list of tips. The calculations run in your browser and each tool explains the assumptions behind its result.
One £4.99 payment gives you access to all thirteen paid planning tools and all 35 London area day guides. The emergency and healthcare card is free for everyone. No subscription, automatic renewal or scheduled expiry.

The tools
Thirteen paid planning tools and one free safety tool, built for visitors and honest about their limits. In the order you may need them.
Daily Budget Estimator
How much spending money?
Build a realistic London spending allowance for your whole party. Choose age groups, trip length, dining style, travel zones, attractions and shows to get a transparent daily breakdown and trip total.
Your London spending plan
- Separate under-11, 11–15 and 16–17 fare assumptions
- Current TfL daily caps with important exceptions explained
- Budget, moderate and comfortable food benchmarks
- Free or paid sightseeing and theatre allowances
- Calculations run locally in your browser
Spending-money estimate only. Accommodation, travel to London, airport transfers, shopping and insurance are excluded.
Airport transfer calculator
Getting in from the airport
Trains charge per person. A car charges per car. That one difference decides which is cheaper for you, and no timetable can tell you because it doesn't know how many of you there are. Pick your airport and party and it prices every sensible route.
Heathrow, two adults and two under-11s
- Heathrow, Gatwick, Stansted, Luton, City and Southend
- Priced for your whole party, not for one imaginary solo traveller
- Three age bands, because every operator draws the child line elsewhere
- Exact landing time and day, so a 3am arrival isn't told to take the Tube
- Metered black cabs and fixed-price cars kept separate
Checked 22 August 2026. Express trains and taxis shown as ranges, because that's how they're priced.
Tube fare calculator
What your travel will cost
Tell it your zones, your dates and roughly how many journeys a day, and it works out what you'll actually be charged — including the daily and weekly caps that quietly stop you paying once you've spent enough.
A day in Zones 1–2, off-peak
- Day-by-day breakdown of what you'll be charged
- The Monday-to-Sunday weekly cap that catches out midweek arrivals
- Tells you plainly whether to tap or buy a 7 Day Travelcard
- Buses, Hopper transfers and Heathrow included
- Zone finder for your hotel, and a printable summary
Adult fares as at 1 March 2026. Caps frozen until at least March 2027.
Walk it instead
When the Tube is slower
A single stop takes about ninety seconds on the train — and seven more minutes of stairs, waiting and climbing back to the street. This puts the walk against a realistic door-to-door Tube time for any two central stations.
Leicester Square to Covent Garden
- 118 stations across Zones 1 and 2, plus 23 landmarks
- Shows exactly where the Tube's time actually goes
- Cross-river journeys routed via the nearest bridge
- Three walking paces, and an interchange allowance
- Ranks London's most pointless one-stop journeys
Estimates from TfL station coordinates, not routed directions.
Zone finder
Which zone is my hotel in?
Your fare zone decides your single fare, your daily cap and your weekly cap — so it quietly sets what a week of travel costs before you've booked anything. Type a station or a neighbourhood and get the answer, plus what it means for your money.
Staying in Shoreditch
- Every station in TfL's published list
- Search by neighbourhood, not just station name
- Boundary stations flagged — TfL charges the cheaper zone
- What staying further out really costs per week
- Browse every station grouped by zone
Underground stations only. Zones from TfL's published station data.
Attraction pass calculator
Is a London pass worth it?
Select the attractions you genuinely plan to visit, enter the pass price you've been quoted, and compare it with buying the same tickets separately. Free museums are included so they don't accidentally make a pass look better than it is.
Your itinerary against the pass
- Major paid attractions and their checked gate prices
- Your own quoted pass price, including flash sales
- Free museums included as a realistic itinerary check
- Clear saving or overspend for the sights you selected
- Calculations run locally in your browser
Planning estimate only. Confirm current prices and pass inclusions with the provider.
Child & Teen Fare Checker
How should my children travel?
Enter the adults and children in your group to get an age-by-age London travel checklist. It explains under-11 free travel, the Young Visitor discount for ages 11–15, and the practical options for 16 and 17-year-olds.
The rule most visitors miss
- Checks the four-under-11s-per-adult allowance
- Explains Oyster and Visitor Oyster card options
- One step-by-step checklist for the whole family
- Flags airport trains and National Rail exceptions
- Calculations run locally in your browser
*Subject to TfL's accompanying-adult and service rules. Check current rules before travelling.
Luggage Storage Locator
Where can I leave my bags?
Select a station or area, your bag count and storage time. The locator compares the official station counter with typical local app-network pricing, so you can see the likely difference before booking.
Official counter vs local app storage
- Major rail stations and useful central London areas
- Calculates for your number of bags and storage duration
- Keeps official counters separate from app-based shops
- Explains booking, payment and final-price checks
- Calculations run locally in your browser
Planning estimates only. Confirm availability, restrictions and the final price with the provider.
Tipping Calculator
What (if anything) to tip
UK tipping is quieter than visitors expect, and the usual trap is tipping twice. Tell it the bill, whether a service charge is already on it, and where you are — restaurant, pub, taxi or hotel — and it tells you plainly what to add.
£60 restaurant bill
- Spots when a service charge means you're already done
- Restaurants, pubs, taxis and hotels covered separately
- Round-up guidance for taxis, not a fixed percentage
- Per-night and per-bag ranges for hotel staff
- Calculations run locally in your browser
General guidance only, not a fixed rule. Tipping in the UK is discretionary.
Free Museums Savings Calculator
Will free museums cut the cost?
London's national museums are free by long-standing policy, not luck, and most itineraries mix them with paid sights without realising how much that's already saving. Tick what you're planning to visit and see the paid total against the free ones.
A day mixing free and paid sights
- Ten of London's best-known free and paid sights
- Adult and child pricing kept separate
- Clear on the catch — special exhibitions still charge
- Pairs well with the Attraction Pass Calculator
- Calculations run locally in your browser
Planning estimate only. Gate prices change — confirm current prices with each venue.
What to pack for London
Packing for the weather you'll get
Choose your travel month and trip length and get the weather London actually has — average high and low, rain days, sunset time and daylight hours — with a packing list and quantities built from those figures rather than from generic seasonal advice.
Your London packing list
- Met Office 1991–2020 averages for the Heathrow station
- Sunset and daylight hours, so short winter days don't catch you out
- Quantities scaled to your nights, with a laundry point past a week
- Shows the spread around the average, not just a single number
- Printable, with a paperwork checklist covering ETA and adapters
Climate averages describe a typical month, not your particular week — always check a forecast before you fly. Entry requirements are summarised only; confirm yours on GOV.UK.

How they're built
What you can expect from them
Four rules we hold ourselves to on every tool.
Your tool inputs stay private
Every calculation runs in your browser. The travel details you enter into a tool are not submitted to our server.
- Your calculations are separate from checkout
- Anything remembered is stored in your own browser
- No analytics on what you type into a tool
The working is visible
The tools show the figures and assumptions behind the result so you can understand how an estimate was reached.
- Key figures shown beside the result
- Methods and limitations explained
- Links to official sources where useful
Figures are dated
Every tool shows the date its main figures were last checked, so you can judge the information before using it.
- Source dates shown on the relevant page
- Important assumptions stated
- Official confirmation recommended
Honest about the limits
A calculator that pretends to certainty it doesn't have is worse than no calculator. Each tool explains its method and says where it might be wrong.
- Working shown, not hidden behind a result
- Estimates labelled as estimates
- Pointed at TfL's own tools where they're better
Good to know
Questions about the tools
The practical answers.
How do I get access?
One £4.99 payment gives you access to all thirteen paid planning tools and all 35 London area day guides, with no subscription, automatic renewal or scheduled expiry. The London Emergency & Healthcare Card is separate and free for everyone. Payment is handled securely by PayPal. Go to the access page.
Do I need an internet connection?
You need an internet connection to open a protected tool and confirm access. Calculations then run in the page in your browser. The free emergency and healthcare card works offline after you have opened it once on that device.
Do you track what I put into them?
The values you enter into the calculators are processed in your browser and are not submitted to our server. Checkout and access use separate necessary records and cookies, as explained in our Privacy Policy.
How can I tell when the figures were checked?
Each tool shows the relevant source or checking date beside its data notes. Always confirm important fares, routes and prices with the official operator before travelling or buying.
Can I rely on them for an important journey?
Use them for planning and budgeting, not as the last word. Fares depend on the exact stations and route you use, and walking times are calculated estimates rather than routed directions. For a specific journey on a specific day, TfL's own fare finder, journey planner and zone map are definitive, and we link to them from every tool.
Can you build a tool for something else?
Quite possibly — suggestions are welcome and they're where most of these came from. The airport transfer, attraction pass and child fare tools all began with questions visitors repeatedly asked. If there's a London question you keep having to work out by hand, tell us about it.
What should we build next?
These tools exist because visitors kept asking the same questions. If you're working something out on paper before your trip, there's a good chance we can turn it into a calculator.
