Common questions.
How accurate is this fence calculator?
It is a planning estimate based on the dimensions, spacing, product sizes and prices you enter. Verify the final takeoff with your supplier or installer, especially for slopes, corners, gates and local code.
How many posts do I need for a fence?
A simple straight run usually needs one more post than the number of fence sections, plus extra posts for corners and gates. Fence Cost Lab adds those extra points and a waste allowance.
How much concrete goes around each fence post?
That depends on hole diameter, hole depth and the yield printed on your concrete bag. Enter those values in the concrete calculator instead of relying on a generic default.
Can I use my local material prices?
Yes. The cost calculator keeps prices editable so your estimate can use the quote from your local store or contractor.
