Saw kerf and cutting waste calculator
Kerf is the width removed by a cut, not the blade's nominal body thickness. Measure a sample cut when precision matters. Material yield counts finished parts divided by purchased stock; offcuts, saw kerf and end trim are reported separately so you can check the balance.
How to use it
Enter the stock lengths and available quantities, blade kerf and end trim. Add each part length, quantity and optional name, or import a CSV. Calculate, check the offcuts, then print the workshop sheet. Save an order file to move it to another browser.
How are kerf and end trim counted?
End trim is removed from both ends of each stock piece. Between parts, a cut consumes the blade-width kerf. At the stock end, only the material remaining beyond the finished part is removed, up to one kerf; an exact fit needs no cut. Parts, kerf, trim and offcut are counted separately.
