It’s a great question if you really want to take a closer view of the industry before you dig in.
Billboard advertising costs roughly $1,500 to $4,000 in most small- to mid-size US cities, though it can dip as low as $250 in rural areas and can reach $14,000 or even higher in larger markets such as New York City.
You will also need to consider the cost associated with producing and designing your billboard advertisement.
Vinyl is the standard material used for the ad itself because of its resistance to weather. Printing an advertisement on vinyl for a bulletin billboard (14’ by 48’, or almost 700 square feet of material) will cost between $300-$500.
There will also be costs to designing the billboard. Budgeting $500 to $1,000 for billboard design would be wise. But before you make the investment, we recommend that you hire an expert to design the most creative and affordable billboard for you to promote your brand hugely.
