Congestion Charge Calculator

Free Congestion Charge Calculator: quick congestion charge calculator for everyday decisions. No signup needed.

A congestion charge calculator estimates the daily and annual cost of driving into an urban road pricing zone. The London Congestion Charge Zone (CCZ) applies a Daily charge of £15 (2024 rate) to most vehicles entering central London, operative Monday to Sunday 07:00–18:00 (excluding Christmas Day). The Auto Pay scheme reduces this by £2 per day for registered regular drivers. London also operates the Ultra Low Emission Zone (ULEZ), a separate £12.50 daily charge for non-compliant vehicles across a much wider area of Greater London. Loan Payment Calculator helps model total motoring costs including road pricing alongside fuel and running costs.

Other UK cities and international markets operate similar schemes — Stockholm, Singapore, Milan, and New York all apply congestion or road pricing charges. This calculator supports any daily charge rate, making it applicable to any road pricing zone worldwide.

Select your zone type or enter a custom Daily charge rate — check the current charge on the relevant authority's website as rates are revised periodically.
Enter the number of days per year you plan to drive into the zone (e.g. working days only, or including weekends if the charge applies seven days a week).
Apply applicable discounts: Auto Pay (£2/day off the London CCZ standard charge for registered regular drivers), 90% resident discount, or fleet account discount.
The calculator outputs your estimated annual congestion charge cost after all applicable discounts are deducted.

Congestion charge cost calculation

Annual congestion cost = (Daily charge − Applicable discount) × Zone-entry days per year

London CCZ rates (2024): Standard £15.00/day | Auto Pay registered £13.00/day | Resident (90% discount) £1.50/day

Worked example: 200 commuting days/year at the standard £15 daily charge = £3,000/year. Registering for Auto Pay reduces this to £13 × 200 = £2,600/year — a £400 annual saving from a one-time registration step.

Current exemptions and discounts (London CCZ, 2024)

Vehicles currently exempt from the London Congestion Charge include: vehicles registered for disabled road tax or in receipt of qualifying mobility allowance; certain military vehicles; NHS Patient Transport Service vehicles. Note: electric vehicles lost their 100% CCZ exemption in December 2025 — check the current TfL exemption list for your specific vehicle before assuming exemption applies. ULEZ-compliant vehicles (petrol Euro 4 or newer, diesel Euro 6 or newer) avoid the £12.50 ULEZ daily charge but still pay the CCZ daily charge if entering the CCZ boundary. Motorcycles pay a reduced rate. Always verify current exemptions at tfl.gov.uk.

Everyday Life tips and best practices

Register for Auto Pay (TfL's account-based billing system) if you enter the CCZ more than once a month — the £2 daily charge saving from Auto Pay registration adds up to £400+ per year for a daily commuter.
Check whether your journey can begin or end outside charged hours — the London CCZ operates 07:00–18:00 on all days except Christmas Day; travel outside these hours avoids the daily charge entirely.
Consider cycling, public transport, or car sharing for CCZ trips — the daily charge plus parking can make a single central London car trip cost £25–45 all-in, often exceeding the equivalent public transport cost significantly.
Self-employed drivers and sole traders can claim road pricing charges as an allowable business expense against tax — retain all TfL Auto Pay statements as evidence.

London Congestion Charge daily rate (2024): £15 standard | £13 Auto Pay | £1.50 resident (90% discount).
London ULEZ daily charge for non-compliant vehicles (2024): £12.50 per day across the expanded Greater London zone (since August 2023).
Annual revenue from the London Congestion Charge: approximately £250–300 million, ring-fenced for Transport for London transport investment.
Traffic volumes in the London CCZ fell by approximately 10–15% in the years following introduction in 2003 — road pricing demonstrably reduces peak-hour central-area demand.

Common mistakes to avoid

Assuming EV exemption still applies — electric vehicles lost their Congestion Charge exemption in December 2025; check the current TfL exemption list before every year's annual budget.
Confusing the CCZ and ULEZ — these are separate daily charges for different geographic zones and compliance criteria; a vehicle can be subject to both, one, or neither depending on its age and emission standard.
Not paying before the midnight deadline — the standard daily charge must be paid by midnight on the following charging day; failure results in a Penalty Charge Notice of £160 (reduced to £80 if paid within 14 days).
Relying on outdated charge rates — TfL can revise the daily charge, zone boundary, and operating hours; always verify the current rate at tfl.gov.uk before budgeting.

The London Congestion Charge is operated by Transport for London (TfL) under powers granted by the Greater London Authority Act 1999 and the Transport for London (Congestion Charging) Order 2011. The daily charge, discounts, exemptions, and operating hours are set by TfL and are subject to revision by the Mayor of London. Penalty Charge Notices for non-payment are issued under the Road User Charging Schemes (Penalty Charges, Adjudication and Enforcement) (England) Regulations 2013. Similar schemes in other cities operate under their respective local authority powers. Always check current rates and eligibility on the relevant authority's official website before relying on figures in this calculator.
