Work out when your next vehicle service is due and set a reminder before it. Enter the date and odometer reading of your last service, your reading now, and the service interval from your manual or workshop, in km, in months, or both. The calculator shows the due reading, the due date by time, an estimated date by distance, and which comes first. You can also download a calendar reminder.
You supply every interval. This tool does not suggest one for any vehicle.
Use the intervals from your vehicle’s manual or your workshop. This tool does not suggest any interval. Fill in the km interval, the months interval, or both.
Nothing you enter is sent anywhere or stored. The calendar file is created in your browser.
How to use the calculator
- Enter the date of your last service and the odometer reading at that service.
- Enter your odometer reading today.
- Enter the service interval from your vehicle manual or workshop: in km, in months, or both.
- For a date estimate by distance, enter your average km per month. If you leave it empty, the tool uses your two odometer readings, but only once at least 30 days have passed since the last service.
- Press “Calculate next service”, then download the calendar file if you want a reminder.
How the results are worked out
- Due reading = odometer at last service + service interval in km. Km left = due reading − current reading.
- Estimated date by distance = today + km left ÷ your km per day (average per month ÷ 30.4375, or km driven since the last service ÷ days since it).
- Due date by time = last service date + the interval in months. If the due month is shorter, the date moves to its last day.
- Whichever comes first = the earlier of the two dates. If either limit has already passed, the tool says the service looks overdue.
What this calculator does not include
- It does not know the service schedule of any bike or car. Use your vehicle manual or your workshop for the interval, the oil type and the work needed.
- It does not show service costs or parts prices.
- The distance-based date is an estimate that assumes you keep driving at the same rate. A change in how much you drive changes the real date.

Vehicle service reminder calculator FAQs
How do I know when my next service is due?
Add the service interval to the odometer reading and the date of your last service. The interval is in your vehicle manual or given by your workshop. The calculator does the sums and shows whichever limit comes first.
Which interval should I enter?
Enter the figure from your own manual or workshop. We do not suggest an interval for any vehicle.
Can I use only km or only months?
Yes. Fill in one interval or both. If you fill in both, the earlier due date is the one to follow.
Can I get a calendar reminder?
Yes. After you calculate, download the calendar file. It adds a reminder before the due date and an event on the due date.
Is my data stored?
No. The calculation and the calendar file are made in your browser, and nothing you enter is sent to our servers.
