Audited planning profile
This couple ten-year profile applies a 2× editable baseline across 120 model periods to the dishwasher use compare model.
Use the difference between option A and option B; keep the scale and horizon identical for both. Agree on shared inputs and ownership before comparing the two-person result. Use a wide uncertainty range; small recurring assumption errors compound substantially over ten 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.
