Audited planning profile
This standard half-year profile applies a 1× editable baseline across 6 model periods to the school term breakeven model.
Compare the break-even period with the time you realistically expect to keep or use the option. Use this as the central case, then compare a lean and conservative profile. Review the assumptions midway because prices and usage may already have changed.
Public holidays, legal notice periods, calendar conventions, time-zone cutoffs and eligibility rules are not inferred unless entered.
Confirm the governing time zone, official calendar and any contractual or legal deadline.
