Start with the sample garage
The demo shows a 2019 RAV4 Adventure at 64,210 miles. Its previous reading was 63,360 miles; the illustrative pace is about 850 miles per month. This is sample data, not a live reading from a customer’s car.

The starting point for this projection.
Sample pace

Estimated from logged readings in the demo.
Project the mileage point
The sample oil-service card says “near 70,000 miles.” That leaves 5,790 miles from the current reading. At 850 miles per month, the simplified calculation is 5,790 ÷ 850 ≈ 6.8 months. From a late-September 2026 starting point, that lands around April 2027, matching the demo’s illustrative forecast.
Planning estimate: the app’s actual forecast can respond to new readings and its own rate calculation. The simplified division here explains the relationship; it is not a promise that a service will be due on an exact day.
What if driving slows down?
Move the control to see the same 5,790 remaining miles at a different monthly pace. For this teaching example, compare the mileage projection with an illustrative June 2027 calendar limit. The demo itself says only that its calendar deadline is later; this date is added here to show the comparison.
At 850 miles/month, the mileage point is roughly 6.8 months away. In this example, mileage arrives before the illustrative calendar limit.
The manufacturer’s interval itself does not change as you move the control. Only the estimate of when the odometer may reach it changes. See how mileage and time deadlines work.
History and conditions still matter
A forecast needs a reliable starting service record. When the last completed service is unknown, it should remain unknown rather than appearing as a precise due date. The exact maintenance action and interval come from the manufacturer’s instructions for your vehicle and driving conditions. The RAV4 Adventure guide explains those source notes; the records guide explains what to save.
