Mobility budget
Company car or mobility budget?
Start from the car you are entitled to. We calculate what it costs you net, and what the same budget yields if you trade it in.
Net cost through the benefit in kind: ≈ €68 per month
In return you drive a fully paid car: no own purchase, insurance, maintenance or fuel.
Estimated annual budget: ≈ €10,579
If you spend everything in pillar 2 (bicycle, public transport, rent or mortgage within 10 km of work), every euro is fully exempt: €882 net spending power per month.
If you have everything paid out as cash (pillar 3), a 38.07% special contribution comes off but no tax: €546 net cash per month.
Converting everything, the budget yields at best €949 per month more than what the car costs you. In return, you arrange and pay for your own transport.
Rule of thumb: if you live close to work or drive little privately, the budget often wins. If you drive a lot, the car usually remains the strongest choice.
Indication. Budget per the statutory formula (catalogue value x 25% plus fuel component at 0.4440 euro/km, third quarter of 2026), capped at 20% of annual pay, minimum €3,233 and maximum €17,244. The CO2 solidarity contribution comes on top in reality. Net car cost at your marginal rate. Your employer determines the exact budget calculation (formula or actual costs).

The federal mobility budget lets you trade a (right to a) company car for an annual budget: in 2026 at least 3,233 and at most 17,244 euros (capped at 20 percent of your gross annual salary). You spend it on a more environmentally friendly car, sustainable mobility or housing close to work; the remainder is paid out in cash after a social security contribution.
The three pillars
Pillar 1: an environmentally friendly car; from 2026 only fully electric cars qualify. Pillar 2 is fiscally the most favourable (fully exempt): (electric) bicycles and subscriptions, public transport, shared mobility, and even your rent or mortgage repayment if you live within 10 kilometres of work or mainly work from home. Pillar 3 is the balance: cash at the end of the year, after an employee contribution of 38.07 percent but without tax.
How much is your budget?
The budget is based on the total employer cost of the car you are entitled to (TCO): either the actual annual costs or a statutory formula. In 2026 a minimum of 3,233 euros applies and a maximum of 20 percent of your gross annual salary, with an absolute ceiling of 17,244 euros. For an average mid-range car the budget often lands between 6,000 and 10,000 euros per year.
Who is it attractive for?
If you live close to work, like cycling or drive little, pillar 2 often yields more net benefit than the car itself, especially through the rent or mortgage option. If you drive a lot or long private distances, the company car usually remains stronger. Calculate both scenarios with the benefit calculator on the company car page and the gross-to-net calculator.
Frequently asked questions
Am I entitled to the mobility budget?
Only if your employer introduces it (their choice) and you have a company car or are entitled to one under the car policy. Your employer may attach conditions to eligibility but must apply the scheme consistently. Ask your HR department or raise it during pay negotiations.
Does the mobility budget count towards my pension and holiday pay?
No: the budget replaces a benefit (the car) and is not gross pay. The pillar 3 balance does build certain social rights through the special contribution, but your holiday pay and year-end premium are not calculated on it. Keep that in mind when weighing pay against budget.
