Rebar Cost Calculator
Rebar cost is driven by weight, unit price per kilogram, and waste for offcuts and laps. This calculator also supports labor cost for bending, tying, and placing rebar.
What Is Rebar Cost?
Rebar cost estimates the total material and labor expense for steel reinforcement in concrete. It is calculated from rebar weight, price per kg, and a waste allowance for offcuts and laps. Adding labor covers bending, tying, and placing rebar cages.
Formula: Weight x Price per unit x (1 + Waste%)
Example
Formula: Weight x Price per unit x (1 + Waste%) = 800 kg x 0.75 per kg x (1 + 5%) = 630.00
Enter rebar weight, unit price, and waste percentage to estimate cost.
Tip: Add extra for laps and offcuts.
Step-by-step calculation
- Enter rebar weight and unit price.
- Add a waste percentage.
- Calculate the total cost.
How this is calculated
Cost = rebar weight times price per kg, plus wastage (3–5%) and fixing labor.

FAQ
- How do I calculate rebar cost by hand?
- Multiply weight by price per kg, then by (1 + waste%). Add labor if needed.
- What is the formula for rebar cost?
- Cost = Weight x Price per kg x (1 + Waste%). Example: 800 kg x 0.75 x 1.05 = 630.
- Rebar cost vs steel cost
- Rebar is a specific grade of steel for concrete; general steel cost may include fabrication.
- What units should I use?
- Use kg for weight and per kg for price.
- Does this include chairs or spacers?
- No, material cost only. Add chairs and ties separately if needed.
