The bend allowance is the length of the bend as measured on the materials neutral axis. Here is where geometry and trigonometry come into play. Bend allowance = [(0.017453 × Inside bend radius) + (0.0078 × Material thickness)] × Complementary Bend angle. You can insert the value of the inside bend radius as determined by the 20 percent rule.
