Rebar Cut List Calculator: Turn a Bar Schedule Into Quantities, Weight and Stock Cuts

Paste reinforcement lines in a simple format and generate a consolidated cut list. The tool totals quantities and lengths by diameter and can also produce a practical first-pass stock-bar cutting plan.

Enter the reinforcement schedule

One line per item: Mark | Quantity | Diameter mm | Cut length m. Example: B1 | 12 | 16 | 4.80

Why a cut list needs more than total steel weight

Two reinforcement schedules can have the same total steel mass but very different fabrication requirements. A useful cut list must preserve the individual cut lengths and quantities because stock-bar optimization depends on how pieces fit together.

What the calculator does

It parses each schedule line, expands quantity, groups pieces by diameter, calculates theoretical mass from nominal diameter, then attempts a simple longest-first packing of pieces into stock bars. Kerf is deducted from usable stock length for each cut after the first piece.

Why this is a first-pass fabrication plan

Real bar bending schedules include bend shapes, hooks, bend allowances, machine constraints, preferred stock lengths, coupler details, end trims and shop practices. The packing algorithm here is intentionally transparent and conservative rather than claiming to replace a fabricator's production software.

Important: The generated cut plan is an estimating aid. Always compare it with the approved bar bending schedule and fabrication requirements before cutting reinforcement.

FAQs

Can I paste dozens of lines?

Yes, each non-empty line is processed independently. Keep the four fields separated by vertical bars.

Does it calculate bend allowance?

No. Enter the final fabrication cut length from the approved schedule. Use the dedicated bend allowance tool when deriving lengths from bend geometry.

Does it optimize all diameters together?

No. Different diameters are never mixed into one stock-bar plan.
