Worked example

20.00 venue + 10.00 travel + 15.00 ammunition + 0.00 other = 45.00. The figure describes the costs you included.

How the calculation works

The calculator sums amounts as whole cents to avoid binary decimal rounding errors. Enter an attributable portion of a bulk cost when that is the basis you intend. Do not mix the full purchase price and the same portion used.

What the result does not establish

The result is not proof of spending. An estimate remains an estimate. It does not transfer to Coldbore automatically.
