Calculate your TMT requirement quickly. Use the preliminary estimate if you are still budgeting, or the BBS calculator if you already have your bar bending schedule.
A rough steel quantity for budgeting, worked out from your built-up area.
Enter your built-up area and number of floors to see an estimated range.
This is only a preliminary estimate for budgeting purposes. Actual reinforcement steel quantity depends on the structural design, structural drawings and Bar Bending Schedule (BBS). The final quantity should be confirmed by a qualified structural engineer.
Add one line for every bar size in your schedule. Lengths are in metres.
| Diameter | No. of Bars | Length / Bar (m) | Total Length | Weight | Actions |
|---|
Optional. Many contractors add a small allowance for cutting and lapping losses.
Enter at least one complete bar size above to see your total.
Please note: This tool totals your quantity from the bar details you enter, using the standard theoretical unit weight of d²/162 kg per metre. Actual delivered weight can vary slightly within permitted rolling tolerances. The result is a quantity calculation, not a structural design – the bar details themselves should come from drawings prepared by a qualified structural engineer.
