Martian gravity penalty

To get off earth's surface & achieve orbit, a rocket must first get above the atmosphere. I've heard this takes about 2 km/sec and is known as the gravity penalty.

I would guess a ship leaving the surface of Mars would also need to get above Mars' atmosphere before doing the big burn. Does anyone know what the Martian gravity penalty would be?

Thanks in advance,
