How the calculation works
Planned spend = tool + missing batteries/charger + accessories + support equipment + delivery + chosen allowance. Remaining budget = spending limit − planned spend.
Use the result with care
This adds your entries; it does not prescribe suitable equipment or an adequate safety budget. An allowance is a planning choice, not a sourced estimate. Do not remove equipment required for the task just to make the result fit.
