Audited planning profile
This freelance ten-year profile applies a 1.5× editable baseline across 120 model periods to the passport renewal buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Separate personal and business costs, unpaid time and tax reserves. Use a wide uncertainty range; small recurring assumption errors compound substantially over ten years.
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.
