25% of membership dues to Toastmasters International is redistributed back to the district. This money is entrusted to the district leadership team so it can carry out its mission and achieve major goals of the organisation. The District team prepare a budget for the coming year (submitted to Toastmasters International no later than September 30) and this is the guideline for how much money is available to be spent.

Toastmasters International has a ton of information on district finances available here: https://www.toastmasters.org/leadership-central/district-leader-tools/district-management/district-finance.aspx
