Estimate Your Black Cab Fare
Enter your journey details below to get a quick estimate. This tool uses practical tariff assumptions and common extras to give you a realistic fare range.

How this black cab price calculator works
Black cab fares are influenced by more than just miles traveled. Time in traffic, time of day, and fixed extras can all push the final amount up or down. This calculator combines those factors into a simple estimate so you can budget before you travel.
Instead of trying to copy every local tariff rule exactly, this tool is designed for practical planning. You get a total fare estimate, a reasonable low-to-high range, and a cost-per-passenger split if you are sharing the ride.
1) Distance and travel time both matter
A common mistake is to estimate a black cab ride by distance alone. In real city journeys, traffic and signals can heavily affect price because cabs charge for time as well. That is why this calculator asks for both:
- Distance (miles) — captures the route length.
- Travel time (minutes) — captures congestion and slower city movement.
- Waiting time — includes stops or delays you already expect.
2) Tariff periods change your fare
Most black cab systems use different pricing bands depending on day and time. You can choose from day, evening/weekend, or night/holiday-style rates. Night and peak periods usually cost more per mile and per minute.
3) Extras are often forgotten
Flat fees can make a noticeable difference, especially on short rides. For example, airport drop-off charges or booking fees can add several pounds quickly. This is why the calculator includes optional tick boxes for typical add-ons.
Example journeys and expected costs
To give you a feel for results, here are common scenarios:
- Short inner-city run: 2 miles, 15 minutes, day tariff — usually a lower fare band, but still affected by traffic.
- Cross-city evening trip: 6 miles, 35 minutes, evening tariff — moderate to higher due to time and tariff uplift.
- Late-night airport transfer: 12 miles, 50 minutes, night tariff + airport fee — often significantly higher than daytime equivalents.
Tips to get a more accurate black cab estimate
- Use map apps for realistic time and distance, not just distance.
- If traveling at rush hour, add a few extra waiting minutes.
- Include all expected fixed fees before confirming your budget.
- Use passenger split to compare solo vs shared trip cost.
- Treat the high-end estimate as your safer budget number.
Black cab vs ride-hailing: when is a cab a better choice?
Ride-hailing can be cheaper in some moments, but black cabs can be competitive during surge periods and may offer advantages in busy centers where pickup reliability matters. If you value predictable service, local driver knowledge, and legally regulated fare structures, a black cab can still be an excellent option.
Frequently asked questions
Is this an official TfL fare calculator?
No. This is an independent estimator designed for planning and budgeting. Official fare meters and local authority tariffs always control the final fare.
Why does my final fare differ from this estimate?
Actual routes, diversions, sudden traffic changes, and specific local rules can all affect the meter. Think of this tool as a smart pre-trip guide.
Can I use this for business travel budgeting?
Yes. It is useful for quick expense forecasts, especially when you include realistic travel time and extras. For reimbursement, always keep the official receipt.
Final thoughts
A black cab fare is usually easiest to understand when you break it into components: base fare, distance, time, waiting, and extras. This calculator does exactly that in seconds. Use it before your trip to avoid surprises and make better travel decisions.
