About Service Cost Per Year Calculator

Annual servicing cost is services per year times the average cost, where the average blends minor services with the more expensive major one that comes round every third or fourth interval. Time-based intervals also apply, so a low-mileage car may still need annual servicing.

Formula

Servicing cost

services per year = annual mileage / interval; average cost blends minor and major services

In particular, this calculator does not take inflation or tax into account.
Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Does low mileage mean less servicing?

Not proportionally. Oil degrades with time as well as use, so most schedules specify whichever of distance or twelve months comes first.

Is a main dealer worth the premium?

For warranty compliance and complex diagnostics, often yes. For routine servicing on an older car, an independent specialist typically costs 30-50% less.
