Our Methodology

How We Calculate Value

We look up the individual retail price of every product inside each calendar, then let you personalise the value based on what you'd actually use.

Individual Retail Price

The total cost of every product if you bought each one separately at its current retail price. This is typically close to the value stated by the brand.

Prices and availability are sourced from retailer websites and may change.

Personal Value

Mark products you'd skip and we subtract them from the total. Marking "want" helps us learn your preferences for better recommendations.

You don't have to vote on every product — only skip the ones you know you wouldn't use.

Why this matters: Even one product you'd never use changes what a calendar is really worth to you. We help you see that before you buy.
