Subscriptions end date, lower price when getting closer to that date

Hi,

I'm organizing the layout of a website of a sport organisation, there you have to pay annually. But the sport year runs from January until december, and our prices drop when the year advances.

For example

• When you join in January it'll cost you 100$
• When you only join in March it only costs you 80$

Is it possible to set such tings up? I couldn't find anything like this in my research.

greetings Glenn
