Subject: Re:How much do you tip a massage therapist for a 60 minute massage? Standard tip for massage is flat rate, not percentage. 30 minutes= $5- $10, 60 minutes= $15- $20, and 90 minutes= $25 to $30. (Obviously this varies based on whether or not your needs were met.) Also, if you belong to a Massage Envy or similar chain, those massage therapists are paid a very low wage.
