How it works
- Price per comparison unit = Price ÷ (Items per pack × Quantity × f)
- Worked example: 4 ÷ 0.5 kg = 8/kg; 5.25 ÷ 0.75 kg = 7/kg
- Supported input limits: Entries: 2–6
Assumptions and limitations
Amounts use the selected currency without conversion. Rates, prices, fees and index values are assumptions you supply, not current offers or legal tax rates. Financial simulations retain full period precision and stop at 1200 periods; displayed currency uses its minor units. Taxes, fees and market changes are included only where entered.
