The charge applies in its set hours (check current times and rates on TfL: they change): auto-pay avoids the GBP 90+ penalty for a forgotten day and shaves admin. It stacks with ULEZ for non-compliant vehicles: a non-compliant car in central London pays BOTH daily. Residents inside the zone get a heavy discount: worth checking if you're borderline on the boundary.
What The Congestion Charge Calculator Works Out
- Per week: days in the zone multiplied by the daily charge. GBP 15 a day across a four-day central-London working week is GBP 60. The charge applies in its set hours, which have shifted over the years, so the rate is an input and TfL's site holds the truth.
- Per year: the weekly figure multiplied by working weeks: GBP 2,700 plus for that four-day pattern, before parking joins at central rates that often double it. The totals are engineered to exceed the annual travelcard they compete with; that is the policy working as designed since 2003.
- What else it buys: the annual total against a zones 1-2 travelcard, the comparison the charge was built to make drive-in commuters perform.
- Central parking and fuel (advanced): the daily costs that sit beside the charge. Central parking alone can match or exceed the charge, and fuel for the drive is the third line.
- ULEZ stacking (advanced): a non-compliant vehicle pays the Congestion Charge and ULEZ together, about GBP 27.50 a day, the sum that has largely retired the old diesel from the West End.
- Residents' discount (advanced): registered residents inside the zone get 90% off, so the card shows the discounted daily and annual charge. The exemption architecture has narrowed steadily: the electric exemption sunset as EVs mainstreamed.
- All-in per year and per charged day (advanced): charge, ULEZ, parking and fuel together, annually and per day. Auto-pay prevents the forgotten day's GBP 90 plus penalty, the difference between a charge and a fine as a lifestyle.
- Versus the annual travelcard (advanced): the all-in driving cost against the travelcard price you enter, and which wins by how much. Driving that looks cheaper here still carries the car's own depreciation, insurance and servicing.
- Break-even days (advanced): the days a week below which all-in driving costs less than the travelcard, for occasional drivers weighing a hybrid of park-and-ride at the zone's rail perimeter and the odd drive in.
- Days table (advanced): the charge, all-in cost and travelcard comparison for 1 to 5 days a week. Paying is defensible for tool-carrying trades and multi-stop work the railways cannot do, which is why vans dominate the zone's paying traffic; through-drivers simply route around a zone that was never aimed at them.
