It depends on the size of your yard and the severity of the slope. A professional landscaping company will likely charge anywhere from $100 to $300 to level a sloped yard, but you could do it yourself for much less. If you have a small yard with only a slight slope, you could probably use some rubble (e.g., broken concrete, bricks, tiles) to fill in the low spots and create a more level surface. If you have a larger yard or if the slope is more severe, you'll likely need to bring in some topsoil or sand to fill in the low spots and create a more level surface.

It depends on the size of your yard and the severity of the slope. Generally, it costs around $4-8 per square foot to have a yard leveled. So, for example, if your yard is 1000 square feet and it's severely sloped, it will likely cost between $4000 and $8000 to have it leveled.
