Calculators for decisions made before cutting material.
Five calculators, each for a decision that costs money if wrong: cutting dimension, material yield, cost per part, production balance. All run in your browser, no account required, and your data never leaves your device.
Metal Weight
Weight of a part from sheet metal, tube, bar or profile, by material and dimensions. The foundation of every accurate quote, because material is bought by kilogram.
Open calculator →Press Brake Bend Allowance
Bend deduction and the cutting dimension for the blank. A half-millimeter error over four bends can put the part outside assembly tolerance.
Open calculator →Plywood Nesting Yield
How many parts fit in a sheet, how many sheets you need, and how much waste remains. The sheet is the largest variable cost line in a furniture factory.
Open calculator →Cardboard Cost per Box
Dies, die-cutting and setup divided by quantity, plus the run size where material preparation becomes negligible. Run volume decides price, not cardboard quantity.
Open calculator →Aggregate from Rubble
Distribution across four size fractions, recovered reinforcement, and financial balance with your own pit and transport rates. All prices are yours to set.
Open calculator →Each calculator comes from a guide explaining why that number matters and what happens when it is wrong. If you want the reasoning behind the figure, the guides are here.
The same calculator on your phone, even offline
The weight calculation works the same way in the Android app, together with the press brake flat pattern, time and cost estimates for laser cutting, and building a quote price. All calculations run on the phone, so it works in a hall with no signal, in the warehouse or at the customer's site.
No account, no ads, no permissions, and no data collection. Your prices per kilogram and machine costs are saved locally and are there every time you open the app.
