Pipe Material Takeoff Calculator
Turn a run length into a material list: how many sticks to order with waste, how many couplings join them, how many hangers the Massachusetts code calls for, plus your fittings. Copy the list straight into a text or an order.

How the takeoff is figured
- Sticks to order = ceil(run × (1 + waste %) ÷ stick length). Waste covers cut-offs and mistakes.
- Couplings = sticks laid end to end in the run − 1, figured on the run itself (ceil(run ÷ stick length) − 1), so the waste allowance doesn't add joints that aren't there.
- Hangers = ceil(run ÷ spacing) + 1, with the spacing from 248 CMR 10.11(4) for the material, size and orientation. See the hanger calculator for the full table.
- Fittings are added as you enter them. Soldered, threaded or glued, each one is a joint to make and a fitting to buy.

Study aid — confirm with the current 248 CMR and your inspector. Hanger intervals are from 248 CMR 10.11 as published by Cornell LII (amended effective 12/8/2023). The list is an estimate for a straight run; check it against the actual layout before ordering.
