Estimate the standard charge for a vehicle class before you sign up. No account or card needed. The starting example is a Birmingham van over two chargeable days.
£8.00 per chargeable day × 2 days. This assumes your vehicle must pay the standard charge. It does not check emissions, exemptions or discounts.
Use the official GOV.UK vehicle checker before driving or paying. A class rate alone cannot tell you what your own vehicle owes. CAZ Cost is an independent service.
GOV.UK defines a chargeable day as midnight to midnight. Crossing midnight can cover two chargeable days. This calculator does not calculate a route or your time inside a zone. London charges are separate schemes and are not included in this form.
These are transcribed rates, not a live council feed. Birmingham's £8 van rate and Bath's £9 van rate were checked against council pages on 8 October 2026. Check the linked sources for current conditions.
