Big Brother 13 (U.S.) Voting Chart

Notes
 * 1) The HouseGuest with a yellow box is paired with the current week's Head of Household, and is immune from nomination for the week.
 * 2) The HouseGuest with a brownish box survived an eviction vote or lost their partner during the first three weeks of the game, and received a "Golden Key" as a reward, granting them – among other perks – automatic immunity until ten HouseGuests remain.
 * 3) The Power of Veto competition was played as individuals. Due to the fact that the duos were still in play, the PoV winner had a choice to remove the nominated duo from eviction.
 * 4) A live battle was held after the eviction and before the Head of Household competition on Day 41 to determine which evicted HouseGuest would be able to return to the House. The viewing public voted all week for Keith, Cassi, Dominic or Brendon to participate in the live battle. Brendon won the public vote and competed against Lawon, the then most recent evictee. Brendon won the battle and was reinstated as a full HouseGuest eligible to win.
 * 5) Week 7 was a double eviction week. Following the first eviction, the remaining HouseGuests played a week's worth of game – including HoH and Veto competitions, and Nomination, Veto, and Eviction ceremonies – during the remainder of the live show, culminating in a second eviction for the week.
 * 6) As Head of Household, Kalia was forced to break the tie on Day 55.
 * 7) Porsche opened Pandora's Box on Day 56 and the remaining six were put into new duos for the week. The new duos are Adam & Shelly (A), Jordan & Rachel (B), and Kalia & Porsche (C).
 * 8) As Head of Household, Rachel was forced to break the tie on Day 67.
 * 9) During the finale, the jury members voted for which finalist should win Big Brother and in a 4–3 vote, Rachel was crowned the winner of Big Brother 13.
