7. Real example: calculation of a trip Moscow - Rostov-on-Don
Let's consider a step-by-step calculation for a passenger car Kia Rio (category B), traveling from Moscow to Rostov on weekdays during the day:
- Route: Moscow (118 km) → Rostov-on-Don (1060 km).
- Payment areas:
- 118–550 km (Moscow—Voronezh): 1 850 ₽.
- 550–1060 km (Voronezh—Rostov): 2 300 ₽.
- Total without discounts: 1 850 + 2 300 = 4 150 ₽.
- Discounts:
- Payment through the application (0% commission).
- Purchasing a round-trip ticket: 10% → 3 735 ₽ one way.
- Fuel: 50 l × 50 ₽/l = 2 500 ₽.
- Refueling on the highway (price is 1 ₽/l higher): +50 ₽.
- Total cost of the trip: 3,735 (road) + 2,550 (fuel) = 6 285 ₽.
For comparison: on a free route the costs will be ~4 500 ₽ (fuel only), but travel time will increase from 12 to 15 hours.
If you frequently use the M4, apply for a “T-pass” transponder - it gives a discount of up to 15% and simplifies payment. For example, on the Moscow–Rostov route the savings will be ~600 ₽ one way.
