Free tools: service interval

Workshop service interval calculator.

Most service schedules say 'every so many kilometres or months, whichever comes first'. This works out which one comes first.

The vehicle

From the vehicle's service schedule.

Enter 0 if you do not know; the date then comes from the time interval only.

Fix the highlighted fields to see the result.

How it works

The date by time is the last service date plus the interval in months; a date such as 31 August moves to the last day of a shorter month. The date by distance is the last service date plus the number of weeks it takes to drive the interval at your average distance per week. The next service is due on whichever date is earlier. When time comes first, the odometer shown is an estimate at your average distance. With no weekly distance entered, no odometer estimate is shown.

Driving habits change, so treat the distance date as an estimate. Always follow the vehicle manufacturer's service schedule.
