Fence Concrete Bag Estimate

Estimate concrete bags for fence posts by post count, hole size, bag yield, and waste.

Count posts

Include line posts, end posts, corner posts, and gate posts.

Use hole diameter and depth to estimate concrete volume per post.

Multiply by post count, divide by bag yield, and round up to whole bags.

Gate posts and corner posts may need larger holes or more concrete than line posts.

Can I use dry-setting concrete?

Some products are designed for dry setting, but follow the product instructions.

How much extra should I buy?

Add extra for oversized holes, uneven digging, and gate posts.

Does post size matter?

Yes. A larger post displaces more volume, but rough estimates often ignore this for margin.

Open the calculators and enter your dimensions to estimate materials before you shop.
