How it's calculated

Service due = the earlier of (last service date + interval in months) and (today + the days it takes to cover the remaining km). Remaining km = service interval − (current odometer − odometer at last service). Days to cover them = remaining km ÷ (average km per month × 12 ÷ 365.25).

Average km per month is calculated automatically = (current odometer − odometer at last service) ÷ days since the last service × 30.4. It needs at least 30 days of history. If no service date is entered, it uses the purchase date and assumes the car was new. You can overwrite the value at any time, and the dates update using your number.

Insurance expiry = policy start date + term in years − 1 day.

PUC expiry = test date + validity in months.

Warranty end = the earlier of (purchase date + warranty years) and the date you are expected to reach the warranty km limit, based on your current odometer and average monthly driving.

Status labels: Overdue if the date has passed, Due today, Due soon within 30 days, otherwise On track. Dates are estimates. Always confirm with your insurance policy, PUC certificate, service book and warranty booklet.

Frequently asked questions

How is my next service due date worked out?

Service is usually due at whichever comes first: a number of months since the last service or a number of kilometres driven. The calculator works out both dates from your last service date, odometer readings and average monthly driving, then shows the earlier one.

What service interval should I enter?

Use the interval in your car's service book or owner's manual, as it differs by manufacturer and model. The 10,000 km or 12 months pre-filled here is only an example value.

When does my car insurance expire?

A policy normally runs for the chosen term from its start date and ends the day before the anniversary. For example, a 1-year policy starting on 15 March ends on 14 March of the next year. Check the exact end date on your policy document.

What happens if my car insurance lapses?

Driving without valid insurance is not permitted in India, and a break in cover can lead to losing no-claim bonus benefits or needing an inspection when you renew. Renewing a little before the expiry date avoids these problems. Confirm the details with your insurer.

How long is a PUC certificate valid?

The validity is printed on your PUC certificate and can depend on the vehicle and state rules. Enter the validity in months from your certificate. The 12 months pre-filled here is only an example.

How does the warranty end date work?

Most car warranties end at whichever comes first: a time limit (for example 3 years) or a kilometre limit (for example 1,00,000 km). Enter the terms from your warranty booklet. The calculator estimates when you will cross the km limit from your driving rate and shows the earlier date.
