Audited planning profile
This freelance three-year profile applies a 1.5× editable baseline across 36 model periods to the home lighting unit model.
Use the per-unit result to compare vendors, formats or operating choices on the same basis. Separate personal and business costs, unpaid time and tax reserves. Run an adverse case for inflation, downtime and changing demand over three years.
Local tariffs, taxes, seasonal efficiency and regulated charges are not inferred automatically.
Check a recent bill, device specification and current tariff before committing to a purchase or retrofit.
