There’s a formula, but typically it increases $100 each election cycle. It’s $2700.00 from each adult in the family for the primary, and the same for the General. That’s to his FEC account.
No limits to the SuperPAC

From the contribution page at TedCruz.org:
“1. The first $2,600 from any single individual’s contribution shall go to the Ted Cruz for Senate primary election account. The next $2,500 shall go to the Jobs, Growth and Freedom Fund for that individual’s 2014 contribution. The next $2,600 will go to the Ted Cruz for Senate general election account. The next $2,500 shall go to the Jobs, Growth and Freedom Fund for that individual’s 2014 contribution.”
I didn’t see a Presidential FEC account at FEC.gov yet. However, candidates are allowed to move money between their own FEC election accounts. A donation at TedCruz.org would find its way into Presidential Campaign accounts.
