Sweat equity
Sweat equity is a party's contribution to a project in the form of effort and toil, as opposed to financial equity such as paying others to perform the task. Sweat equity has an application in business for example where the owners put in effort and toil to build the business, in real estate where owners can do D.I.Y. improvements and increase the value of the real estate and in other areas such as an auto owner putting in their own effort and toil to increase the value of the vehicle.
