There is no predetermined amount that is "too much" for a Christmas gift because it might differ based on individual preferences and spending limits. However, it's crucial to take into account your relationship with the recipient of the gift as well as your own financial situation.
A larger gift might be suitable if you are close with the recipient; but, if you are not as close, a smaller gift might be more appropriate. It's also crucial to take into account your own budget; you shouldn't ever strain your finances in order to purchase a gift.
It's crucial to keep in mind that a meaningful present need not be pricey. A sincere letter or a handcrafted present might be just as memorable as something more pricey.
In general, the most crucial thing is to express your gratitude and appreciation through the gift you offer. The amount of thought and effort you put in are more important than the money you spend.
It's also crucial to take into account the recipient's social mores and traditions; for instance, gift-giving may be less valued in some cultures than in others.
