Annual cost of driving through a charge zone.

A 15 daily charge for 4 commute days a week over 46 working weeks is 2,760 a year. With 30% of trips deductible as business use, the personal portion drops to 1,932. Many drivers under-estimate this until they total it.

What the result means

Gross annual cost is the simple total. Net cost takes off the share you can recover via business expenses. Compare this to the cost of public transport, parking outside the zone, or switching to an exempt vehicle.

The math handles any city's daily charge — Low Emission Zones, Ultra Low Emission Zones, downtown congestion fees, Stockholm or Milan all work the same way.

Quick example

With daily charge of 15 and commute days per week of 4 (plus weeks per year of 46 and business portion of 30%), the result is 2,760.00. Change any figure and watch the output shift — it's often more useful to see the pattern than to memorise the formula.

Which inputs matter most

You enter Daily Charge, Commute Days Per Week, Weeks Per Year, and Business Portion. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.

What's happening under the hood

Annual gross is daily charge times weekly days times weeks per year. Personal net subtracts the business-deductible share. The tool does not validate eligibility for business deductions — confirm with your accountant. The formula is listed in full below. If the number looks off, you can retrace the calculation by hand — that's the point of showing the working.

Why see the number at all

Small recurring spending is invisible by design — every individual transaction is forgettable. Compounded over years, the total often surprises. Seeing the figure doesn't mean you typically need to cut the spending; it just makes the trade-off conscious.

What this doesn't capture

The tool prices the money; it can't weigh the enjoyment. A coffee habit, gym membership, or streaming bundle might cost what the math says but deliver value that's harder to quantify. Use the number to make the trade-off visible — the decision is yours.
