A concrete budget isn't just "square footage times price per foot" — it's five separate pieces, and most first-time budgets only account for two of them. This guide walks through material, labor, site prep, permits, and contingency planning, with a full sample worksheet, a fair payment schedule, and the mistakes that most often blow a budget over.
A standard concrete slab costs $6-$12 per square foot installed in 2026, averaging around $8/sq ft — but that number bundles material, labor, reinforcement, and finish together. This guide breaks down each piece, explains why small slabs cost more per square foot, and compares real DIY vs. professional totals across three project sizes.
Bag prices average $4.50-$6.50 for 80 lb concrete mix in 2026, but the real project cost includes tax, delivery, sub-base, and reinforcement too.
