Marriott To SPG Point Conversion

Conversion Calculator

Calculate the conversion of Marriott Points to Starpoints and vice-versa using this calculator. Starpoints are from the old Starwood Preferred Guest program.

This Starwood Preferred Guest Points to Marriott Rewards Points Calculator converts points between both programs. Starpoints are a thing of the past as of August 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. If you didn't have a linked account, you will be asked to update some information and you will receive one when you create a Marriott Bonvoy account.

Marriott Rewards Points were renamed Marriott Bonvoy Points under the new program in Feb 2019.

Point Conversion Calculator

Input the total number of Starpoints or the total number of Marriott Rewards Points and it will reflect the amount it is equal to in the adjacent field. The SPG to Marriott point conversion ratio is 3 to 1. That means 1 Starpoint is worth 3 points in Marriott's Rewards program. This is a simple calculator just to help people with the math.
