The spending limit increases every cycle due to inflation. The FEC estimates that the limits for the primary election will be $40.9 million, of which a candidate must abide by state limits of 65.4 cents per person of voting age population in a state, or $817,800, whichever is greater. Certain fundraising expenses (up to 20 percent of the expenditure limit) and legal and accounting expenses incurred solely to ensure the campaign's compliance with the law do not count against the expenditure limits.
