How much tzedakah does the Beit Yosef recommend giving?

The Beit Yosef, authored by Rabbi Yosef Caro, discusses the obligation of tzedakah (charity) and specifically recommends that individuals should give one-fifth of their wealth. This guideline reflects a balance between being generous and ensuring that one does not overextend their financial capacity to the detriment of their own needs or those of their family.

In Jewish law, giving one-fifth is considered a significant act of kindness and fulfills the mitzvah of supporting those in need while still allowing the giver to maintain a reasonable level of personal financial integrity. The recommendation of one-fifth stems from a combination of biblical interpretations and Talmudic discussions that highlight the importance of generosity while also recognizing the practical limitations faced by individuals in their obligation to give.

While it's beneficial to give more than this amount when possible, especially in times of greater prosperity or need, the Beit Yosef offers this specific guideline as a foundational level of giving that is both attainable and commendable.
