How to interpret the result
A comparison is useful only when its quantities and periods match. The result helps organise a decision; it does not predict future prices, household behaviour or unexpected costs.
Hold the quantity or time horizon steady while changing a price or option. Then check whether delivery fees, restrictions or a changed purchase quantity would reverse the comparison.
Common mistakes to avoid
- Do not compare different pack sizes without converting to a common quantity.
- Avoid mixing monthly and annual figures without a deliberate conversion.
- Include the actual terms of discounts, subscriptions and payment plans where supported.
Assumptions and sources
Enter ticket costs yourself. Car fixed costs paid regardless are excluded; include depreciation/maintenance per km as needed.
