Quick Overview

  • Starwood Preferred Guest (SPG) is an old rewards program that earned rewards called Starpoints.
  • Starpoints were worth about 2 cents each on average and sat alongside Hyatt in terms of most valuable hotel rewards points.
  • SPG was bought out by Marriott in 2018. If you had Starpoints in your SPG account, they were converted to Marriott Rewards Points as long as you had a linked Marriott Rewards account at the time.
  • The Marriott Rewards program was re-branded as Marriott Bonvoy and all Starwood credit cards were officially re-named February 2019.

Use this calculator to calculate the conversion of Starpoints into Marriot Rewards points and vice-versa. This calculator and info is pretty much here for historical reasons.
