TOGAF provides a set of tools that help an architect to execute his or her work. If you ask yourself whether a TOGAF certification leads to a higher salary, ask yourself this question:
Would a painter request a higher price for a painting because he or she bought a new brush? If there were two painters with the same skills, the one with the better brush would definitely create the better outcome. However, if the painter with the better brush has only little skills, the outcome of his or her work is very likely to be not as good as the one from the other painter.
A TOGAF certification can be compared to the brush in the above story. Having a TOGAF certification is therefore likely to not have a strong positive impact on your salary.
