Our data shows no toll plazas on the fastest route, so the cost of the drive is essentially fuel. On a drive this long that is unusual: if you switch to a national highway or a new expressway you may meet plazas that aren't in the NHAI dataset yet, so keep a small buffer.

Around ₹2,094 one way for a petrol sedan (fuel ₹2,094 + toll ₹0), or ₹4,188 for a same-day return. Split between four people that is ₹524 each, one way.
Plan on about 6 h 10 min including short breaks. Free-flowing traffic can do it in 4 h 32 min, but towns, trucks and plaza queues usually add time.
No toll plazas sit on the fastest route, so commercial vehicles pay no toll either.
Yes, plazas charge the same fee in both directions, so the Tirunelveli to Kochi toll is the same ~₹0 for a car. Fuel cost differs only if you fill up at Tirunelveli's state price.
Fees are revised every 1 April and some plazas change mid-year, so treat results as a close estimate. Spotted a wrong fee or a missing plaza? Tell us — we fix reported errors within 72 hours and log them on our corrections page.
